Description

Pen and touch input system and controller

Technical Field

The present invention relates to a pen and a controller, and more particularly, to a controller for controlling a touch input system and apparatus including a sensor section capable of interacting with a stylus.

Background

A variety of touch input devices such as a mobile phone, a smart phone (smart phone), a notebook computer (laptop computer), a digital broadcasting terminal, a personal digital assistant (personal digital assistants, PDA), a portable multimedia player (portable multimedia player, PMP), a navigator, a touch screen tablet (tablet PC), a tablet PC, an ultra book (Ultrabook), and a wearable device (wearable device) are provided with touch sensors.

In such a touch input device, the touch sensor may be located on a display panel on which an image is displayed, or may be located at a part of the touch input device. The user interacts with the touch input device by touching the touch sensor, which may provide an intuitive user interface to the user.

The user may use a stylus for accurate touch input. The stylus may be classified into an Active (Active) stylus and a passive (passive) stylus according to whether a battery and electronic components are provided therein.

Active styluses have the advantage of excellent basic performance compared to passive styluses, being able to provide additional functions (pen pressure, hover, button), but have the disadvantage that the pen itself is expensive, requires a power supply, is a charging means, and therefore actual users are not many except for some advanced uses.

Passive styluses have the advantage of being inexpensive and requiring no battery compared to active styluses, but have the disadvantage that accurate touch recognition is difficult to achieve compared to active styluses. However, recently, in order to realize a passive stylus capable of precise touch recognition, techniques of an electromagnetic resonance (Electro Magnetic Resonance, EMR) system and a capacitive (capacitive) resonance system have been proposed as an induced (inductive) resonance system.

Although the EMR system is advantageous in terms of writing/drawing quality as a core function of the stylus pen, it is necessary to add an EMR sensor panel and an EMR driving IC in addition to the capacitive touch panel, and thus there is a disadvantage in that the thickness is thick and the cost is high.

The capacitive resonance mode is a mode in which a general capacitive touch sensor and a touch controller IC are used, and the performance of the IC is improved without additional cost, thereby supporting a pen touch.

In the EMR mode or the capacitive resonance mode, the touch sensor must have a large amplitude of the resonance signal to more accurately recognize the touch of the stylus, so that the frequency of the driving signal transmitted to the stylus is almost the same as the resonance frequency of the resonance circuit built in the stylus. However, in the conventional EMR system or capacitive resonance system, even if the resonance frequency is identical to the frequency of the driving signal, there is a problem in that signal transmission is difficult due to a very large attenuation of signal transmission. As a result, although many touch controller IC suppliers have long tried, they have not generated sufficient output signals, and thus, there has been virtually no commercial enterprise that has succeeded in mass production so far.

Therefore, how to design the internal resonant circuit and the structure of the pen becomes a very important factor in order to manufacture an EMR system or a capacitive resonant stylus capable of generating a maximum output signal.

Detailed Description

Various embodiments of the present specification are described below with reference to the drawings. However, the technology described in this specification is not intended to be limited to the specific embodiments, and is to be understood as including various modifications, equivalents (equivalents), and/or alternatives (equivalents) of the embodiments of this specification. With respect to the description of the drawings, like reference numerals may be used for like components.

The size and thickness of each of the components shown in the drawings are arbitrarily shown for convenience of explanation, and therefore the present invention is not necessarily limited to the drawings. In the drawings, the thickness is exaggerated for clarity of illustration of the layers and regions. In the drawings, the thickness of a part of layers and regions is exaggerated for convenience of explanation.

Also, when a portion of a layer, film, region, sheet, or the like is described as being "on" or "over" other portions, this includes not only the case immediately after "on" other portions but also the case with other portions in between. Conversely, where a portion is referred to as being "on" another portion, it means that there are no other portions in between. The term "on" or "above" a reference portion means that the reference portion is located above or below the reference portion, and does not necessarily mean that the reference portion is located "on" or "above" the gravitational counter direction side.

In this specification, the expressions "having", "including" or "including" etc. mean that the feature (e.g., a numerical value, a function, an action, or a constituent element of a component, etc.) is present, and the presence of an additional feature is not excluded.

In this specification, the expression "a or B", "at least one of a or/and B" or "one or more of a or/and B" may include all possible combinations of items listed together. For example, "a or B", "at least one of a and B" or "at least one of a or B" may refer to (1) a case comprising at least one a, (2) a case comprising at least one B or (3) a case comprising at least one a and at least one B.

The expressions "first", "second", "first" or "second" used in the present specification may modify various components, irrespective of order and/or importance, but are used to distinguish one component from another, and are not limited thereto. For example, the first user device and the second user device may represent different user devices, regardless of order or importance. For example, a first component may be named a second component, and similarly, a second component may be named a first component without departing from the scope of the claims set forth in this specification.

When it is described that a certain component (for example, a first component), (functionally or communicatively) is connected (operatively or communicatively) to another component (for example, a second component), it is to be understood that a certain component may be directly connected to another component or connected through another component (for example, a third component). In contrast, when a description is given of a "direct connection" or "direct access" of a certain component (for example, a first component) to another component (for example, a second component), it is understood that no other component (for example, a third component) exists between the certain component and the other component.

The description "configured to" used in the present specification may be used interchangeably with "suitable for", "having capability (having the capacity to)", "designed to", "changed to", "made to" or "capable of being made to", for example. The term "configured (or arranged) to" may not necessarily mean only "specifically designed (specifi cally designed to)" in hardware. Conversely, the expression "a device configured to" may in some cases mean that the device may be "capable of" along with other devices or components. For example, the phrase "a processor configured (or arranged) to perform A, B and C" may refer to a special purpose processor (e.g., an embedded processor) for performing the action or a general purpose processor (e.g., CPU or application pr ocessor) that may perform the action by executing one or more software programs stored in a memory device.

The terminology used in the description is for the purpose of describing particular embodiments only and is not intended to be limiting of the scope of other embodiments. Singular descriptions may include plural descriptions in other cases where it is not explicitly indicated herein. Including technical or scientific terms, which may have the same meaning as commonly understood by one of ordinary skill in the art to which this specification refers. Terms defined on a general dictionary among terms used in the present specification may be interpreted as having the same or similar meaning as the context of the related art, and are not interpreted as ideal or excessively formal meanings unless explicitly defined in the present specification. According to circumstances, even the terms defined in the present specification do not exclude the embodiments of the present specification.

Touch input devices according to various embodiments of the present description may include, for example, at least one of a smart phone, a tablet (tablet personal computer), a mobile phone, a video phone, an electronic book reader (e-book reader), a notebook (laptop personal computer), a netbook computer (netbook computer), an ambulatory medical device, a camera, or a wearable device (webcam). According to various embodiments, the wearable device may include at least one of an ornamental type (e.g., a watch, a ring, a bracelet, a foot chain, a necklace, glasses, a contact lens, or a head-mounted device (HMD)), a fabric or clothing integrated type (e.g., an electronic garment), a body attached type (e.g., skin pad or tattoo), or a bioimplanted type (e.g., implanted circuit (implantable circuit)).

The controller according to an embodiment of the present invention is a controller for controlling a touch input device including a sensor section capable of interacting with a stylus pen, described below with reference to required drawings.

In describing the controller according to the embodiment of the present invention, a pen and a touch input system including a touch input device including a sensor portion and a control portion controlling the sensor portion, and a stylus capable of interacting with the touch input device will be described in detail.

Fig. 1a is a conceptual diagram illustrating a pen and touch input system including a stylus and a touch input device.

Referring to fig. 1a, the stylus 10 may receive (or upload) a signal output from the touch input device 2 or the touch screen 20 near the touch screen 20 of the touch input device 2 and transmit (or download) a signal to the touch screen 20.

Fig. 1b is a schematic diagram for explaining uploading (uploading) and downloading (downloading) of the pen and touch input system shown in fig. 1 a.

Referring to the left side view of fig. 1b, the coil inside the stylus 10 of fig. 1a forms an electromotive force (V2, or Vem f) in the case of uploading. Referring to the right side diagram of fig. 1b, an electromotive force (V1, or Vemf) is formed at the sensor portion of the touch input device 20 in the case of downloading. That is, the coil inside the stylus and the sensor portion of the touch input device work as a transformer (transducer) with each other.

Fig. 1c is a schematic diagram for explaining the interval between the + drive channel and-drive channel in the case of uploading.

Referring to fig. 1c, in the case of uploading, there is an optimal interval for the interval between the + driving channel and the-driving channel according to the shape and position of the inductor inside the stylus. Based on a typical stylus design, it is preferable that the + drive channel and-drive channel are separated by at least one channel spacing (4 mm).

Fig. 2 is a schematic diagram schematically illustrating a signaling action between the stylus and the touch input device.

Referring to fig. 2 (a), the touch screen 20a includes a digitizer 29, a display panel 251, a sensor section 21, and a window 22.

In the case of an electromagnetic resonance (EMR) type pen in a passive stylus, the digitizer (digitizer) 29 resonates the magnetic signal B in a resonant circuit included in the stylus 10a when transmitting the magnetic signal B to the EMR type stylus 10 a. In this case, digitizer 33 receives resonant magnetic signal B from stylus 10 a.

The digitizer 29 may be attached to the lower portion of the display panel 251, and includes a flexible printed circuit board (Flexible Printed Circuit Board, FPCB) formed with a plurality of conductive antenna loops and a ferrite sheet (ferrite sheet) shielding a magnetic field generated by the antenna loops, and shielding eddy currents that may be generated in other electronic components and constituent elements when the antenna loops form the magnetic field.

On the FPCB, a plurality of antenna loops for sensing a resonance signal input position are configured as a plurality of layers. One antenna loop has a form overlapping with at least one other antenna loop in the Z-axis direction. The thickness of the FPCB is thick. Therefore, it is difficult to reduce the thickness and size of the touch input device 2 when the digitizer 29 is used.

In the case where such a digitizer 29 is mounted on the foldable/flexible touch input device 2, the FPCB attached to the folded region may be deformed when folded. Repeated folding may cause stress to the wiring member forming the antenna loop, and as a result, damage to the wiring member may be caused. The ferrite sheet shields the influence of the magnetic field generated by the antenna loop on the inside of the touch input device 2. The ferrite sheet is also thick, and is easily deformed when the touch input device 2 is folded, and may be damaged by repeated folding.

Referring to fig. 2 (b), the touch screen 20b includes a display panel 251, a sensor portion 21, and a window 22.

In the case of the stylus 10 including the resonance circuit, when the electrode (or pattern) of the sensor portion 21 transmits the magnetic signal B to the stylus 10, the resonance circuit included in the stylus 10 resonates the magnetic signal B. In this case, the electrodes (or pattern) of the sensor portion 21 may receive the resonating electromagnetic signals E and/or B from the stylus 10. When the electrode (or pattern) of the sensor unit 21 is formed of a metal mesh (metal mesh) having a small resistance, a magnetic signal from the stylus pen 10 can be detected.

Also, the touch screen 20b does not require an additional unit or module for transmitting the magnetic signal to the stylus pen 10 as compared with the digitizer 29, and thus can achieve a thin touch screen 20b, which is also advantageous in terms of manufacturing costs.

Referring to fig. 2 (c), the touch screen 20c includes a loop coil 264, a display panel 251, a sensor portion 21, and a window 22.

In the case of the stylus 10 including the resonant circuit, the loop coil 264 resonates the magnetic signal B in the case of transmitting the magnetic signal B to the stylus 10, the resonant circuit included in the stylus 10. In this case, the electrodes (or pattern) of the sensor portion 21 may receive the resonating electromagnetic signals E and/or B from the stylus 10.

In contrast to the digitizer 29, the loop coil 264 does not receive the magnetic signal B for detecting the touch position, and therefore the wiring structure is simple, and the touch panel 20c can be thinned. Thereby, the touch input device 2 can be thinned and miniaturized. Also, the loop coil 264 may be formed in a variety of locations in a variety of sizes, and thus such a touch screen 20c may also be suitable for use with the foldable/flexible touch input device 2.

Loop coil 264 may include a substrate on which the antenna loop is located and a ferrite sheet. The antenna loop may be formed of a conductive material such as copper, silver, or the like. The antenna circuit may be located on the same layer as the sensor portion 21 in addition to the substrate, and in this case, the antenna circuit may be formed of a high-transmittance, low-impedance conductor material such as a metal mesh, ITO, graphene, or silver nanowire. And the antenna loop may be located at the lower portion of the window, in which case the substrate may not be included in the loop coil 264.

In the structure, the sensor section 21 may include a plurality of electrodes (or patterns) for detecting touch coordinates. For example, the sensor section 21 may include a plurality of first touch electrodes for detecting touch coordinates in a first direction and a plurality of second touch electrodes for detecting touch coordinates in a second direction intersecting the first direction. Although the sensor portion 21 is shown as one layer in fig. 2, the first touch electrode and the second touch electrode may be located on different layers, may be disposed so as to overlap each other, may be disposed so as not to overlap each other, and may be disposed between the first touch electrode and the second touch electrode without being limited thereto.

Referring to fig. 2 (d), the touch screen 20d includes a display panel 251, a sensor portion 21, and a window 22.

In the case of the active stylus 10' including a resonant circuit, the resonant circuit included in the active stylus 10' resonates with a power source (for example, a battery for storing electric energy (including a secondary battery) and a capacitor such as an electric double layer capacitor (electric double layered capacitor, EDLC)) within the active stylus 10 '. In this case, the electrodes of the sensor portion 21 may receive the resonating electromagnetic signals E and/or B from the stylus 10'. When the electrode (or pattern) of the sensor portion 21 is formed of a metal mesh having a small resistance, a magnetic signal from the stylus pen 10' can be detected. The active stylus 10' may include a circuit for outputting electromagnetic signals E and/or B having a predetermined frequency with a power source in addition to the resonant circuit in order to generate the electromagnetic signals. Also, the active stylus 10' may include both a resonant circuit and a circuit outputting electromagnetic signals E and/or B having a predetermined frequency.

The touch screen 20d is also capable of receiving electromagnetic signals from the stylus 10 'without transmitting magnetic signals to the stylus 10'. That is, since the touch panel 20d does not require an additional unit or module for generating a signal for resonating the resonant circuit included in the stylus pen 10', the touch panel 20d can be thinned and miniaturized, and is advantageous in terms of power consumption and manufacturing cost.

The touch input device 2 according to the embodiment is explained below with reference to fig. 3.

Fig. 3 is a block diagram schematically illustrating a touch input device capable of interacting with a stylus.

As shown, the touch input device 2 may include a wireless communication section 210, a memory 220, an interface section 230, a power supply section 240, a display section 250, a touch section 260, a control section 270, and the like.

Fig. 4 is a schematic diagram illustrating a stylus according to an embodiment.

The stylus of fig. 4 includes a resonant circuit section 12 within a housing.

The resonance circuit 12 is an LC resonance circuit, and resonates a driving signal output from the touch panel 20 of fig. 2 and 3. The driving signal may include a signal (e.g., sine wave, square wave) having a frequency corresponding to the resonance frequency of the resonance circuit portion 12, and the like. For resonance, the resonance frequency of the resonance circuit portion 12 and the frequency of the driving signal should be the same or extremely close. The resonant frequency of the stylus 10a, 10b complies with the design value of the resonant circuit section 12 of the stylus 10a, 10 b. When the sensor unit 21 in fig. 2 (b) or the loop coil 264 in fig. 2 (c) generates an electromagnetic field based on a driving signal, the resonance circuit unit 12 of the stylus pen 10a or 10b resonates with a signal received by a change in the magnetic field.

The elements of the stylus 10a, 10b may be housed in a housing. The housing may have a cylindrical shape, a polygonal column shape, a cylindrical shape with at least a part thereof being curved, a convex column (enasis) shape, a truncated pyramid (frustum of pyramid) shape, a truncated cone (circular truncated cone) shape, or the like, and is not limited to this shape. Since the interior of the case is hollow, the elements of the touch pens 10a and 10b such as the resonant circuit 12 can be accommodated therein. Such a housing may be composed of a non-conductive substance.

As shown in fig. 4 (a), the EMR-type stylus 10a includes a resonant circuit portion 12. The resonance circuit section 12 includes an inductor section 14 and a capacitor section 13. The inductor section 14 includes a ferrite core 115 and a coil 116 wound on the outside of the ferrite core 115.

The EMR-mode stylus 10a may further include a tip 11a. The tip 11a is an end portion of the stylus 10a, and may be disposed to penetrate the ferrite core 115, or may protrude from the ferrite core 115, as shown in fig. 4 (a). The tip 11a may be a non-conductor or a conductor, and may be constituted by an electrode core made of a hard resin mixed with a conductive metal or conductive powder, for example. However, the tip 11a may not be electrically connected to the resonance circuit 12.

The ferrite core 115 may be, for example, a ferrite material in the shape of a cylindrical pattern. The ferrite core 115 may be formed with a through hole in the axial direction for insertion through a predetermined diameter (for example, 1 mm) of the tip 11a. The ferrite core 115 may be formed in a cylindrical shape, a polygonal column shape, a column shape at least a part of which is curved, a convex column shape, a truncated pyramid shape, a truncated cone shape, a ring shape (toroid), a ring shape (ring) or the like.

The coil 116 may be wound over the entire length of the ferrite core 115 in the axial direction, or over a portion of the length. The coil 116 is electrically connected to the capacitor portion 13.

The capacitor portion 13 may include a plurality of capacitors connected in parallel. The capacitors on the printed substrate may have different capacitances and may be trimmed within the manufacturing process.

As shown in fig. 4 (b), the stylus 10b of the electrically coupled resonance ECR (Electrically Coupled Resonance, ECR) system includes a conductive tip 11b and a resonance circuit portion 12. The resonance circuit section 12 includes an inductor section 14 and a capacitor section 13 and can be grounded (Ground). The inductor portion 14 includes a ferrite core 115 and a coil 116 wound around the outside of the ferrite core 115.

The conductive tip 11b may be entirely or at least partially formed of a conductive substance (e.g., metal, conductive rubber, conductive fabric, conductive silicone, etc.), not limited thereto.

Fig. 5 is a conceptual diagram specifically illustrating an inductor portion of the stylus pen shown in fig. 4 (a) and (b).

Referring to fig. 5, the inductor portion 14 includes a ferrite core 115 and a coil 116 wound around the ferrite core 115.

Here, the inductance (inductance) of the inductor section 14 is determined by the following < equation 1 >.

[ math 1 ]

As can be seen from < equation 1>, the inductance L is proportional to the permeability (permaability) of the ferrite core 115, the cross-sectional area of the coil 116, and the square of the number of windings, and inversely proportional to the winding length of the coil 116.

The design of the inductor portion 14 in the resonant circuit portion 12 housed in the stylus pen shown in fig. 4 (a) and (b) is extremely important. In particular, in terms of the design of the inductor section 14, as shown in fig. 6, the inductance L and Q values are extremely important parameters. Where the Q value is an amount representing the coil characteristic as a resonant circuit element, given q=2 efL/R. Where L, R is the inductance and resistance of the coil, respectively, and f is the frequency. The sharper the resonance characteristic can be obtained by using a coil having a larger Q value.

In the stylus design shown in fig. 4 (a) and (b), L should have a sufficiently large self-resonance (self-resonance) frequency for the frequency to be used, and preferably the Q value has a maximum value at the frequency to be used. To meet this, the material of the ferrite core, the kind of coil, and the winding method (winding scheme) need to be optimized. Also, a method capable of obtaining a high output signal while maintaining the diameter of the pen is required.

In the following embodiments, the design of an optimum stylus pen in the material of the ferrite cores, the type of the wires of the coils, and the winding method (winding scheme) will be described.

(1) Ferrite core material

Manganese (Mn) and nickel (Ni) are used as materials of the ferrite core used in the present embodiment.

(2) Wire type

Enameled wires and stranded wires are used as the types of wires of the coil used in the present embodiment.

As shown in fig. 7, an enameled wire 100 is a wire formed by coating an insulating varnish 102 on the surface of a copper wire 101 and heating the coated wire at a high temperature, and is used for winding and wiring electronic equipment, communication equipment, electronic equipment, and the like. In this embodiment, an enameled wire having a total thickness T of 0.2mm, a wire diameter Φ of 0.18mm, and a coating thickness T of 0.01mm is used.

As shown in fig. 8, a LITZ wire 200 is a special insulated wire in which a plurality of thin insulated wires 100 (e.g., enamel wires) having a diameter of about 0.1mm are twisted into one strand and covered with an insulating coating 201 of nylon or the like thereon. The twisted wire 200 can reduce the skin effect by increasing the surface area, be used for a coil of a high-frequency circuit, or the like.

In the present embodiment, a twisted wire having a total thickness T of 0.2mm, a wire diameter Φ of 0.06mm, and a coating thickness T of 0.007mm was used.

(3) Winding mode

In the embodiment of the present invention, a winding method having a multilayer winding structure is used in order to obtain a sufficient inductance value (i.e., a sufficient number of windings) in a limited space of the stylus pen. Specifically, as shown in fig. 9 (a) and (B), two types of multilayer winding systems are used.

The winding method of fig. 9 (a) is the simplest winding method, and is a sequential layer winding method (sequential layer windings cheme) in which one layer is directly wound on the wire after the winding of the lower layer is completed. Here, the method (a) of fig. 9 is a method in which the winding of the upper layer is directly started at the position where the winding of the upper layer ends, and is hereinafter referred to as a U-shaped winding method.

The winding method of fig. 9 (B) is a method (alternate layer winding scheme) in which adjacent winding layers are alternately wound, and the winding of the adjacent layers is a method in which the winding of the adjacent layers is inclined in a zigzag manner. This is hereinafter referred to as a zigzag winding method. Specifically, the method is a method in which the second layer of wire is wound around the first layer of wire in sequence, the third layer of wire is wound between the first layer of wire and the second layer of wire, the fourth layer of wire is wound around the second layer of wire, and the fifth layer of wire is wound between the second layer of wire and the fourth layer of wire. The zigzag winding method can minimize the voltage difference between the windings of adjacent layers, so that the winding self-capacitance (self-capacitance) can be reduced. The self-capacitance of the wire, which is one of the parasitic capacitances, is a parameter indicating the electric field energy (electric field energy) stored in the wire.

Comparative experiment 1 (comparing characteristic values under different materials)

The Q value was measured by changing the material of the ferrite core to manganese, nickel, and magnesium in a state where the wire is wound in a U-shaped winding manner with the enamel wire as the type of the wire of the coil.

The measured Q value is not enough to realize the product because the Q value of the material of each core has almost no characteristic difference.

Comparative experiment 2 (comparison of characteristic values for different winding types)

The Q values of the inductor 1 and the inductor 2 manufactured by using the wire types of the coil as the enameled wire and the twisted wire, respectively, were measured in a state where manganese (Mn) was used as the material of the ferrite core and wound in a U-shaped winding manner.

Fig. 8 is a schematic diagram showing Q values of the inductor 1 and the inductor 2 measured during frequency change by an E4980A precision LCR meter (E4980A precision LCR meter) of KEYSIGHT TECHNOGIES company (german technology).

Fig. 10 a shows a waveform showing a change in Q value of the inductor 1 (manganese core/wire/U-turn type), and b shows a waveform showing a change in Q value of the inductor 2 (manganese core/wire/U-turn type).

The Q value shows almost the maximum at a frequency (frequency f 1) around 400kHz for the inductor 2 made of twisted wire, and shows almost the maximum at a frequency (frequency f 2) around 150kHz for the inductor 1 made of enameled wire.

By comparing a and b of fig. 10, the maximum Q value of the inductor 2 is almost 1.5 times greater than the maximum Q value of the inductor 1. Therefore, it is known that the twisted wire is more excellent than the enamel wire as the coil of the inductor forming the resonance circuit of the stylus pen.

The maximum Q value of the inductor 2 measured in comparative experiment 2 was also only the target value (Q _{Target object} ) To the extent of 1/2.

Comparative experiment 3 (comparison of characteristic values in different winding modes)

The Q value was measured for the inductors 3 to 5 which were manufactured by changing the winding method to U-shape and zigzag shape with the wire enamel wire and the twisted wire as the types of wires in the state where manganese (Mn) was used as the material of the ferrite core.

Fig. 11 is a schematic diagram showing Q values of the inductors 3 to 5 measured during frequency change by an E4980A precision LCR meter (E4980A precision LCR meter) of KEYSIGHT TECHNOGIES company (german technology).

Fig. 11 a shows a waveform showing a change in Q value of the inductor 3 (manganese core/wire/U-shaped winding method), b shows a waveform showing a change in Q value of the inductor 4 (manganese core/wire/zig-zag winding method), and c shows a waveform showing a change in Q value of the inductor 5 (manganese core/twisted wire/zig-zag winding method) with respect to frequency.

As is clear from the waveform c of fig. 11, the inductor 5 manufactured by the litz wire/zigzag winding method exhibits almost the maximum value of Q value at a frequency (frequency f 3) around 300 kHz. The Q value of the inductor 4 manufactured by the wire-enamel/wire-zigzag winding method and the Q value of the inductor 3 manufactured by the wire-enamel/U-wire winding method show almost the maximum value at a frequency (frequency f 2) around 150 kHz.

As is clear from a, b, and c of fig. 11, the maximum Q value of the inductor 5 is almost 1.5 times higher than the maximum Q value of the inductor 4, and is two times or more higher than the maximum Q value of the inductor 3. Therefore, it is known that the winding method of the inductor forming the resonant circuit of the stylus pen is superior to the U-shaped winding method.

However, the inductor 5 (manganese core/strand/zigzag winding method) measured in comparative experiment 2 was also only a commercially required target value (Q _{Target object} ) To a 3/4 extent.

Comparative experiment 4 (comparison of characteristic values under different core materials)

In this embodiment, manganese and nickel are used as the ferrite core material, and it is known that nickel generally has a magnetic permeability of 200 to 300 and manganese has a magnetic permeability of 3000 to 5000.

Since the magnetic permeability of manganese used in the present embodiment is about 15 times higher than that of nickel, the number of windings of manganese can be reduced by about 4 times as compared with that of nickel in order to obtain the same inductance value assuming that the sectional area and length of the coil are the same. Therefore, manganese is more effective than nickel from the viewpoint of the number of windings.

In addition, the inductor portion 14 has a complicated structure including a coil wound around a core, and thus parasitic capacitance is also formed. The Q value decreases due to such parasitic capacitance, and thus has a problem of decreasing the amplitude of the resonance signal.

Parasitic capacitance formed in the inductor portion 14 may occur between each coil of the winding, between the core and the coil, and parasitic capacitance between each coil of the winding may be reduced by the winding method in a zigzag shape as described above.

In the present embodiment, in order to reduce parasitic capacitance between the core and the coil, a core material having a dielectric constant lower than that of manganese was tested, and a nickel core as a material of the ferrite core was tested to be optimal.

An important physical property among manganese and nickel mainly used as ferrite core elements is permeability (permaability), which has an important influence on inductance values as in < formula 1 >. However, manganese and nickel dielectric constants (permatticity) are physical properties that are hardly concerned, and in fact, for nickel, there is almost no information on the data sheet provided by the manufacturing company.

In this embodiment, for confirming the dielectric constants of manganese and nickel, the dielectric constants (permatticity) of manganese and nickel were measured using an E4980A precision LCR meter (E4980A precision LCR meter) of KEYSIGHT TECHNOGIES (german technology) and the measurement results are shown in table 1 below.

[ Table 1 ]

	Dielectric constant of manganese	Dielectric constant of nickel
			Measurement 1	2400	-
Measurement 2	8300	2

Measurement 1 and measurement 2 were measured using an E4980A precision LCR meter (E4980A precision LCR meter) from the same KEYSIGHT TECHNOGIES company (De technology Co.), measurement 1 representing the dielectric constant automatically calculated by the measurement software. From measurement 1, the dielectric constant of manganese was 2400, but the dielectric constant of nickel was not measured.

The measurement 2 was performed by measuring the capacitance, area and distance between ferrite cores and calculating the dielectric constant, and it was found from the measurement 2 that the dielectric constant of manganese was 8300 and the dielectric constant of nickel was 2.

It was confirmed that measurement 1 and measurement 2 have a large difference in the result of the dielectric constant, and particularly in the case of measurement 2, there is a considerable error in terms of capacitance, area, distance, and the like. However, from the results of measurement 1 and measurement 2, it was found that nickel has a dielectric constant at least 1/1000 or less than that of manganese.

In comparative experiment 4, the Q value was measured for the inductor 6 and the inductor 7, which were manufactured by changing the winding method to the U-shape and the zigzag shape in the state where the ferrite core was made of nickel and the wire type was twisted.

Fig. 12 is a schematic diagram showing Q values of the inductor 6 and the inductor 7 measured during frequency change by an E4980A precision LCR meter (E4980A precision LCR meter) of KEYSIGHT TECHNOGIES company (german technology).

Fig. 12 a is a waveform showing a change in Q value of the inductor 6 (nickel core/twisted wire/U-shaped winding method) with respect to frequency, and b is a waveform showing a change in Q value of the inductor 7 (nickel core/twisted wire/zig-zag winding method) with respect to frequency.

As is clear from the waveform b of fig. 12, the inductor 7 fabricated in the nickel core/twisted wire/zigzag manner exhibits almost the maximum value of Q at a frequency (frequency f 5) around 400 kHz. The inductor 6 fabricated in the nickel core/twisted wire/U-shaped winding manner exhibits almost the maximum value of Q value at a frequency (frequency f 6) around 200 kHz. As can be seen from comparing fig. 11 a and b, the maximum Q value of the inductor 7 is almost twice as large as the maximum Q value of the inductor 6.

In addition, it was found that the maximum Q value of the inductor 7 (nickel core/twisted wire/zigzag winding system) measured in comparative experiment 4 almost reached the target value (Q) required for commercial use _{Target object} )。

In comparative experiments 1 to 4 described above, Q values were measured by manufacturing each inductor while changing the combination of the ferrite core material, the type of coil wire, and the winding method (wire winding scheme), and it was found from the test that the highest Q value was obtained when the inductor portion of the capacitive resonant stylus was designed in a nickel core, twisted wire, and zigzag winding manner. It is also known that the maximum Q value of the inductor manufactured by this combination reaches a target value (Q _{Target object} )。

In the present embodiment, experiments were performed using a nickel core as the ferrite core and a stranded wire as the core, but similar results were obtained when a wire in the form of two or more insulated wires (strands) was covered with one coil in addition to the stranded wire, using a material having a dielectric constant of 1000 or less as the ferrite core in addition to the nickel core.

Before describing in detail the pen and the touch input device in the touch input system according to the embodiments of the present invention, the reason why the output voltage (Vout) of the capacitor voltage amplitude (Capacitor Voltage Amplitude, CVA) varies depending on the position of the stylus on the touch screen is described below.

Fig. 13 is a schematic diagram for explaining the variation of the output voltage (Vout) of the capacitor voltage amplitude (Capacitor Voltage Amplitude, CVA) depending on the position of the stylus 10 on the existing touch screen.

Referring to fig. 13, the output of the cva varies with the position of the stylus 10 on the touch screen because the impedance (impedance) ratio on both sides of the sense line centered on the stylus 10 varies.

Based on the long axis of the existing touch screen, the resistance R of a Metal Mesh touch sensor is about 1.2k (ohm), and the capacitor C is about 250pF.

Based on 10 dispersion models (distributed model), at a driving frequency of 300kHz, the impedance (impedance) of the capacitor (capacitor) is about 200 times (120 (ohm) vs. 1/(2e×300k×25 pf) =21 k (ohm)). Thus, a capacitor (capacitor) is a main cause.

Fig. 14 is a schematic diagram for explaining the output voltage (Vout 1, vout 2) of the CVA in fig. 13 depending on the position of the stylus 10 by current sensing (current sensing), and fig. 15 is a schematic diagram for explaining the output voltage (Vout 1, vout 2) of the CVA in fig. 13 depending on the position of the stylus 10 by voltage sensing (voltage sensing).

Referring to fig. 14 and 15, the output voltage of the CVA is different according to the position of the stylus 10 on the sensing line. That is, the closer the stylus 10 is to the sensing circuit portion 50 side, the larger the output voltage of the CVA is, and the farther the stylus is from the sensing circuit portion 50 side, the smaller the output voltage of the CVA is.

Touch input devices according to various embodiments of the present invention are described in detail below with reference to the accompanying drawings.

Fig. 16 is a schematic diagram of a touch input device according to an embodiment of the invention.

Referring to fig. 16, the touch input device according to an embodiment of the present invention includes a sensor part 100 and a control part 500.

The sensor portion 100 includes a plurality of patterns (or a plurality of electrodes). In the present figure, the sensor unit 100 is one embodiment of the sensor unit 21 shown in fig. 2.

The sensor part 100 may include a plurality of first to fourth patterns 101, 102, 103, 104.

The first pattern 101 has a shape extending along a first direction. Fig. 16 shows the first direction as the long axis, but is not limited thereto. For example, the first direction may also be a short axis.

The enclosed structure includes not only the case where the first pattern 101 encloses the second pattern 102 entirely on a plane, but also the case where the first pattern 101 encloses the second pattern 102 on a plane for the most part except for a part.

The first pattern 101 is disposed at a predetermined interval from the second pattern 102.

The second pattern 102 is disposed adjacent to the first pattern 101. For example, the second pattern 102 may be disposed inside the first pattern 101.

The second pattern 102 may include a plurality of main pattern parts and a connection pattern part connecting two adjacent main pattern parts among the plurality of main pattern parts. The main pattern portion may have a diamond shape, but is not limited thereto, and may have various shapes different from the connection pattern portion.

The main pattern portion of the second pattern 102 may have a shape corresponding to the main pattern portion of the first pattern 101, and the connection pattern portion of the second pattern 102 may have a shape corresponding to the connection pattern portion of the first pattern 101.

In the following description one end may be named a first side end and the other end may be named a second side end. One ends of the plurality of first patterns 101 may be electrically connected to the control part 500 through conductive traces.

One end of the plurality of second patterns 102 is electrically connected to the control part 500, and the other end may be electrically connected to each other through a via (via). Wherein the vias at the other ends of the plurality of second patterns 102 may be electrically connected to each other through conductive traces. One end is a position relatively close to the control unit 500, and the other end is a position relatively far from the control unit 500. In the case where the other ends of the plurality of second patterns 102 are electrically connected to each other, the capacitances of the second patterns 102 are added to each other, so that the total impedance can be reduced. And thus has an effect like the other ends AC GND of the plurality of second patterns 102.

Although not shown, the other ends of the plurality of second patterns 102 electrically connected to each other may be grounded.

Although not shown, the other ends of the plurality of second patterns 102 may not be electrically connected to each other, and a predetermined capacitor may be connected to the other end of each second pattern 102.

At least a portion of the first pattern 101 and at least a portion of the second pattern 102 are disposed on the same layer. For example, the first pattern 101 and the second pattern 102 may be disposed on the same layer. The first pattern 101 and the second pattern 102 may be formed on the same layer using a metal mesh (metal mesh).

The third pattern 103 has a shape extending along the second direction. Fig. 16 shows the second direction as the short axis, but is not limited thereto. For example, the second direction may also be the long axis.

The third pattern 103 may include a plurality of main pattern parts and a connection pattern part connecting two adjacent main pattern parts among the plurality of main pattern parts. The main pattern portion may have a diamond shape, but is not limited thereto, and may have various shapes different from the connection pattern portion.

The third pattern 103 may have an opening portion in which the fourth pattern 104 is disposed. The shape of the opening portion may correspond to the outer shape of the third pattern 103. The third pattern 103 may have a structure surrounding the fourth pattern 104. The third pattern 103 is disposed at a predetermined interval from the fourth pattern 104.

The fourth pattern 104 is disposed adjacent to the third pattern 103. For example, the fourth pattern 104 may be disposed inside the third pattern 103. The fourth pattern 104 may include a plurality of main pattern parts and a connection pattern part connecting two adjacent main pattern parts among the plurality of main pattern parts. The main pattern portion may have a diamond shape, but is not limited thereto, and may have various shapes different from the connection pattern portion.

The main pattern portion of the fourth pattern 104 may have a shape corresponding to the main pattern portion of the third pattern 103, and the connection pattern portion of the fourth pattern 104 may have a shape corresponding to the connection pattern portion of the third pattern 103.

The plurality of third patterns 103 and the fourth patterns 104 are arranged parallel to each other.

One end of the plurality of third patterns 103 is electrically connected to the control part 500, and the other end is electrically opened (open). One end is a position relatively close to the control unit 500, and the other end is a position relatively far from the control unit 500. One end of the plurality of third patterns 103 may be electrically connected to the control part 500 through conductive traces.

One end of the plurality of fourth patterns 104 is electrically connected to the control part 500, and the other end thereof may be electrically connected to each other through a via hole. The vias at the other ends of the fourth plurality of patterns 104 may be electrically connected to each other through conductive traces. One end is a position relatively close to the control unit 500, and the other end is a position relatively far from the control unit 500. In the case where the other ends of the plurality of fourth patterns 104 are electrically connected to each other, the capacitances of the respective fourth patterns 104 are added, and thus the total impedance decreases. Therefore, there is an effect like the other end AC GND of the plurality of fourth patterns 104.

In addition, the other ends of the plurality of fourth patterns 104 electrically connected to each other may be grounded.

Although not shown, the other ends of the plurality of fourth patterns 104 may not be electrically connected to each other, and a predetermined capacitor may be connected to the other end of each fourth pattern 104.

At least a portion of the third pattern 103 and at least a portion of the fourth pattern 104 are disposed on the same layer. For example, the third pattern 103 and the fourth pattern 104 may be disposed on the same layer. The third pattern 103 and the fourth pattern 104 may be formed on the same layer using a metal mesh (metal mesh). The third pattern 103 and the fourth pattern 104 may be disposed on different layers from the first pattern 101 and the second pattern 102. For example, the first pattern 101 and the second pattern 102 may be disposed on a first layer, and the third pattern 103 and the fourth pattern 104 may be disposed on a second layer different from the first layer.

The control unit 500 is electrically connected to the sensor unit 100, and can control the operation of the sensor unit 100. With respect to the connection of the control portion 500 and the sensor portion 100, they may be electrically connected to each other by conductive traces.

The control unit 500 may be the touch controller 262 shown in fig. 3, but is not limited thereto. The control unit 500 may be integrated with the touch controller 262 and the display controller 252 shown in fig. 3, integrated with the touch controller 262 and the control unit 270 shown in fig. 3, or integrated with the touch controller 262, the display controller 252, and the control unit 270 shown in fig. 3. Alternatively, the controller 500 may be another controller included in the sensor unit 100. Therefore, the controller 500 according to the present invention is not limited to the touch controller 262 or the controller 270 shown in fig. 3, and can control not only the sensor unit 100 but also the sensor units according to the following embodiments.

The control part 500 may include a plurality of driving circuit parts and a plurality of sensing circuit parts. The plurality of driving circuit parts may include a driving circuit part for touch sensing and a driving circuit part for stylus driving. The plurality of sensing circuit parts may include a sensing circuit part for touch sensing and a sensing circuit part for stylus sensing. Wherein a part of the plurality of sensing circuit parts may perform touch sensing and also perform stylus sensing.

The control part 500 may control the sensor part 100 to operate in any one of a touch sensing mode, an antenna driving mode, and a stylus sensing mode. The control part 500 may connect a plurality of driving/sensing circuit parts to the sensor part 100 according to each mode, and control driving signals to be applied to the plurality of driving circuit parts. For this, the control part 500 may include a plurality of switches for electrically connecting the plurality of driving/sensing circuit parts and the sensor part 100.

Each mode is explained below with reference to fig. 17 to 21.

Fig. 17 is a schematic diagram illustrating a case where the touch input device shown in fig. 16 operates in a touch sensing mode (or 2D sensing mode).

Referring to fig. 16 and 17, in the touch sensing mode, the control part 500 may electrically connect a plurality of driving circuit parts for touch sensing to the first pattern 101 of the sensor part 100. The control part 500 may electrically connect the conductive traces connected to the plurality of first patterns 101 to the plurality of driving circuit parts by controlling the plurality of switches sw.

Also, the control part 500 may electrically connect a plurality of sensing circuit parts for touch sensing to the third pattern 103 of the sensor part 100. The control part 500 may electrically connect the conductive traces connected to the plurality of third patterns 103 to the plurality of sensing circuit parts by controlling the plurality of switches sw.

In the touch sensing mode, the control part 500 simultaneously or sequentially applies a driving signal (or a touch driving signal) for touch sensing to at least one of the plurality of first patterns 101, and receives a sensing signal (or a touch sensing signal) received from at least one of the plurality of third patterns 103. The plurality of sensing circuit parts of the control part 500 electrically connected to the plurality of third patterns 103 may output capacitance variation information included in the input sensing signal at a predetermined voltage value. The control part 500 may detect a touch position by processing the output voltage value.

In fig. 17, the control part 500 is not electrically connected to the plurality of second patterns 102, but may electrically connect the plurality of driving circuit parts to the plurality of second patterns 102 to prevent capacitive coupling (capacitive coupling) between the first patterns 101 and the second patterns 102. Here, the control part 500 may control such that the same driving signal as that applied to the plurality of first patterns 101 is applied to the plurality of second patterns 102. Alternatively, the control unit 500 may control the plurality of second patterns 102 to be applied with a predetermined reference potential when the driving signal is applied to the plurality of first patterns 101.

Fig. 18 is a schematic diagram showing a case where the touch input device shown in fig. 16 operates in an antenna driving mode (or a stylus driving mode, or a stylus uploading mode).

Referring to fig. 16 and 18, in the antenna driving mode, the control part 500 may electrically connect a plurality of driving circuit parts for antenna driving to a plurality of second patterns 102 of the sensor part 100. The control part 500 may electrically connect the conductive traces connected to the plurality of second patterns 102 to the plurality of driving circuit parts by controlling the plurality of switches (sw).

The control part 500 may control a driving signal (or a pen driving signal) outputted from each driving circuit part connected to the plurality of second patterns 102.

For example, the control part 500 may control such that a first driving circuit part of the plurality of driving circuit parts connected to the plurality of second patterns 102 outputs a pulse signal of a predetermined frequency, a second driving circuit part does not output any pulse signal, and a third driving circuit part outputs an inverted pulse signal having a phase opposite to that of the pulse signal output from the first driving circuit part. In this case, a current loop is formed by the second pattern 102 electrically connected to the first driving circuit portion and the second pattern electrically connected to the third driving circuit portion. The formed current loop generates a magnetic field, and the resonance circuit portion of the stylus pen near the sensor portion 100 can be driven by the resonance of the magnetic field.

The control part 500 may control such that any two driving circuit parts among the plurality of driving circuit parts electrically connected to the plurality of second patterns 102 output driving signals (e.g., pulse signals) opposite to each other. Therefore, the control unit 500 can be provided with various modifications to the size and position of the current loop. For example, the control part 500 may control such that the driving circuit parts electrically connected to the two second patterns around the position of the stylus pen output driving signals opposite to each other in the case where the position of the stylus pen is detected, and may control such that the driving circuit parts electrically connected to the two second patterns located at the outermost outlines at both sides of the plurality of second patterns 102 output driving signals opposite to each other in the case where the position of the stylus pen is not detected.

The control unit 500 may form two or more current loops at the same time. Reference is made to fig. 19 for an explanation.

Fig. 19 (a) to (c) are schematic diagrams for explaining a plurality of methods in which the control section 500 applies a pen driving signal for driving the stylus pen to the plurality of second patterns 102 shown in fig. 16. For reference, one second pattern 102 shown in fig. 16 is schematically shown with one line Ch in fig. 19 (a) to (c), each line being one channel Ch.

Fig. 19 (a) shows a case where the stylus pen 50 is located at the center (non-edge area) of the sensor unit 100 shown in fig. 16, for example, on the fifth channel Ch 5. In this case, the control unit 500 may control the plurality of driving circuit units such that the same number of channels Ch2, ch3, ch4/Ch6, ch7, ch8 are applied to the left and right sides with reference to the position of the stylus 50, and pulse signals and inverted pulse signals (or ground) are applied thereto. Specifically, the control section 500 may control such that three, i.e., second to fourth channels Ch2, ch3, ch4 located on the left side of the stylus 50 are pulsed, and control such that three, i.e., sixth to eighth channels Ch6, ch7, ch8 located on the right side of the stylus 50 are inverted pulsed. Fig. 19 (a) shows that pulse signals and inverted pulse signals (or ground) are applied to each of the three channels with reference to the stylus 50, but is not limited thereto. For example, in fig. 19 (a), a pulse signal and an inversion pulse signal (or ground) may be applied to two or one channel each with reference to the stylus 50, or four or more channels may be applied to a pulse signal and an inversion pulse signal (or ground).

Fig. 19 (b) shows a case where the stylus 50 is located at the edge portion of the sensor portion 100 shown in fig. 16, for example, between the 0 th channel Ch0 and the first channel Ch 1. In comparison with fig. 19 (a), the control unit 500 cannot apply pulse signals and inverted pulse signals (or ground) to the same number of channel(s) on the right and left with reference to the stylus 50. In this case, the control unit 500 may control the application of the pulse signal and the inversion pulse signal (or the grounding) to the different number of channels with respect to the stylus 50. Specifically, it may be controlled such that a pulse signal is applied to the 0 th channel Ch0, and an inverted pulse signal is applied to the first to third channels Ch1, ch2, ch 3. Although not illustrated, the stylus 50 may also be controlled such that the 0 th to second channels Ch0, ch1, ch2 are applied with the inversion pulse signals in a case where it is located at the outermost edge of the left side of the 0 th channel Ch 0.

In fig. 19 (a) to (b), the more channels Ch0, ch1, … …, ch19, the more terminals of the control unit 500 for driving each channel are required, and the more the configuration of the driving circuit unit in the control unit 500 is complicated. At least two or more channels adjacent to each other among the channels Ch0, ch1, … …, ch19 can be electrically connected so as to be driven as one channel. Specifically, as shown in fig. 19 (c), two channels are electrically connected to constitute one channel. In the case of such a configuration, the two channels electrically connected are simultaneously supplied with the same signal. Fig. 19 (c) shows that 20 channels Ch0, ch1, … …, and Ch19 are electrically connected to each other to form 10 channels. Although not shown, three of the channels may be electrically connected to each other to form 7 channels, or four of the channels may be electrically connected to each other to form 5 channels.

Fig. 20 is a schematic diagram illustrating a case where the touch input device shown in fig. 16 operates in a stylus sensing mode (or a stylus download mode).

Referring to fig. 16 and 20, in the stylus sensing mode, the control part 500 may electrically connect a plurality of sensing circuit parts for stylus sensing to the first pattern 101 and the third pattern 103 of the sensor part 100. The control part 500 may electrically connect the conductive traces connected to the plurality of first patterns 101 and the plurality of third patterns 103 to the plurality of sensing circuit parts by controlling the plurality of switches sw.

The touch input device according to the embodiment of the present invention has an advantage in that the output voltage values of the plurality of sensing circuit sections are hardly changed with the position of the stylus pen on the sensor section 100 in the stylus pen sensing mode by the configuration of the sensor section 100. The specific principle thereof is described later with reference to fig. 21 (a) to (f).

FIGS. 21 (a) to (f) are for briefly explaining FIG. 20Schematic diagram of the operating principle of the stylus sensing mode.

Fig. 21 (a) is a circuit diagram schematically simulating the sensing circuit portion of the control unit 500 electrically connected to any one of the first patterns 101 shown in fig. 20, and fig. 21 (b) is a circuit diagram schematically simulating the second pattern 102 arranged inside the any one of the first patterns 101.

Fig. 21 (c) is a voltage distribution graph in the circuit diagram of fig. 21 (a), and fig. 21 (d) is a voltage distribution graph in the circuit diagram of fig. 21 (b).

Referring to fig. 21 (a) and (c), when the stylus pen is located near an arbitrary a position on the first pattern 101 that is as far as possible from the sensing circuit portion, a voltage (Vemf, hereinafter referred to as an "induced voltage") induced by a signal emitted from the stylus pen occurs at the a position.

When the induced voltage (Vemf) occurs at the a position, the equivalent capacitance of the first pattern 101 as viewed from the a position to the left decreases, and thus the equivalent impedance increases. Therefore, the induced voltage (Vemf) is almost mostly on the left side of the a position, and the right side of the a position has a voltage almost close to 0 (V), so that the current hardly flows. Further, the voltage near 0 (V) on the right side of the a position gradually drops further due to the equivalent resistance of the first pattern 101, and thus, the voltage is hardly applied to the input terminal of the sensing circuit section.

Referring to fig. 21 (b) and (d), when the induced voltage (Vemf) occurs at the a position, the other ends of the second patterns 102 are electrically connected to each other at the left side of the a position, and therefore the equivalent capacitance seen to the left side of the a position increases, and the equivalent impedance is almost 0. Therefore, since the left side of the a position is 0 (V) and the right side of the a position is open (open) at one end of the second pattern 102, no voltage drop occurs in the equivalent resistance, and the voltage is still Vemf.

As can be seen from comparing fig. 21 (c) and (d), a potential difference corresponding to Vemf exists at any position between the first pattern 101 and the second pattern 102. The potential difference between the first pattern 101 and the second pattern 102, which corresponds to Vemf, causes capacitive coupling (capacitive coupling) between the first pattern 101 and the second pattern 102. Due to the capacitive coupling, as shown in (e) of fig. 21, a current flows from the second pattern 102 to the first pattern 101. As shown in fig. 21 (a), the farther the position of the stylus pen is from the sensing circuit part of the control part 500, the less current is generated in the first pattern 101 itself, but since current flows from the second pattern 102 to the first pattern 101, the current output from the first pattern 101 to the sensing circuit part of the control part 500 is hardly different from the pen position. The control part 500 can sense the position of the stylus pen through the sensing circuit part electrically connected to the first pattern 101 and the third pattern 103.

It can be also understood from fig. 21 (a) to (e) that even if the a position moves to the left or right, the potential difference between the first pattern 101 and the second pattern 102 is kept constant by Vemf. Therefore, the control unit 500 can sense the stylus pen based on a predetermined signal output from the sensing circuit unit, regardless of the position of the stylus pen on the sensor unit 100 and the distance between the sensing circuit unit and the sensing circuit unit.

In the description of fig. 21 (e), it is described that the current flowing from the second pattern 102 to the first pattern 101 is caused by capacitive coupling, but the present invention is not limited thereto. For example, the current flowing from the second pattern 102 to the first pattern 101 may also be caused by magnetic coupling (magnetic field coupling).

The sensor section 100 of the touch input device shown in fig. 16 may be used as a plurality of combinations of the first to fourth patterns 101, 102, 103, 104 for driving (driving) a sensing stylus. The various combinations are shown below in < table 2 >. In the following < table 2>, the '1' refers to the plurality of first patterns 101, the '2' refers to the plurality of second patterns 102, the '3' refers to the plurality of third patterns 103, and the '4' refers to the plurality of fourth patterns 104.

[ Table 2 ]

Referring to < table 2> above, among the plurality of combinations nos. 1 to 32, the plurality of first patterns 101 and the plurality of third patterns 103 sense touches of an object such as a finger. Specifically, the control unit 500 causes the plurality of first patterns 101 to operate as touch driving electrodes and the plurality of third patterns 103 to operate as touch receiving electrodes. Although not shown in the table, the control unit 500 may operate the plurality of first patterns 101 as touch receiving electrodes and the plurality of third patterns 103 as touch driving electrodes.

One or two of the plurality of first to fourth patterns 101, 102, 103, 104 may operate as a stylus driving electrode for driving a stylus through the control part 500. A current loop for driving the stylus pen may be formed using one or two of the first to fourth patterns 101, 102, 103, 104. The X-axis driving may be any one of the plurality of first patterns 101 and the plurality of second patterns 102, and the Y-axis driving may be any one of the plurality of third patterns 103 and the plurality of fourth patterns 104. The driving of the stylus pen can be realized through any one of X-axis driving and Y-axis driving, and can also be realized through two.

At least two of the plurality of first to fourth patterns 101, 102, 103, 104 may operate as a sensing electrode sensing a stylus signal emitted from a stylus. In order to sense a stylus signal while X-axis sensing and Y-axis sensing are required, two patterns among the plurality of first to fourth patterns 101, 102, 103, 104 are utilized. The X-axis sensing may be any one of the plurality of first patterns 101 and the plurality of second patterns 102, and the Y-axis sensing may be any one of the plurality of third patterns 103 and the plurality of fourth patterns 104.

In the above < table 2>, the so-called 'up signal size' refers to the size of a driving signal for driving the stylus pen. Applying the same stylus driving signal to the plurality of first patterns 101 and the plurality of second patterns 102, respectively, and comparing the magnitudes of signals received from the styli, the upload signal is relatively larger in the case of applying the stylus driving signal to the plurality of second patterns 102 than in the case of applying the stylus driving signal to the plurality of first patterns 101.

This is because the other ends of the plurality of second patterns 102 are electrically connected, and thus at least one current loop is formed when two or more second patterns to which a stylus driving signal is applied are appropriately selected, while the other ends of the plurality of first patterns 101 are not electrically connected to each other, and thus the current loop cannot be formed. When a current flows to each first pattern 101, RC of each first pattern 101 is charged, and thus the current flow from one end of each first pattern 101 to the other end is less preferable. Also, since the stylus driving signal applied through the plurality of first patterns 101 is transferred to the plurality of second patterns 102 forming the current loop through capacitive coupling, the capacitive coupling causes signal attenuation at this time.

Also, the upload signal is relatively larger in the case of applying the stylus driving signal to the plurality of fourth patterns 104 than in the case of applying the stylus driving signal to the plurality of third patterns 103.

In the above < table 2>, the so-called 'download (download) signal size' refers to the size of the stylus signal received from the stylus. By receiving the same stylus signal through the plurality of first patterns 101 and the plurality of second patterns 102, respectively, and comparing the magnitudes of the signals, the download signal is relatively larger in the case of receiving the stylus signal through the plurality of second patterns 102 than in the case of receiving the stylus signal through the plurality of first patterns 101. The reason for this is that the other ends of the plurality of second patterns 102 are electrically connected to form a current loop, and the other ends of the plurality of first patterns 101 are not electrically connected to each other, and in particular, a stylus signal is transferred from the plurality of second patterns 102 forming a current loop through capacitive coupling to the plurality of first patterns 101, so that attenuation of a download signal occurs at this time.

Also, the download signal is relatively larger in the case of receiving the stylus signal through the plurality of fourth patterns 104 than in the case of receiving the stylus signal through the plurality of third patterns 103.

In the above < table 2>, the so-called 'stylus (additional channel') means whether an additional channel needs to be constituted for the stylus in addition to touch sensing. Additional channels are required for driving (driving) or sensing (sensing) of the stylus with the plurality of second patterns 102 or/and the plurality of fourth patterns 104 (< marked as 'have' in table 2 >). Whereas no additional channels are required in case of driving or sensing of the stylus while using the plurality of first patterns 101 or/and third patterns 103 for touch sensing (< table 2> marked as 'none').

In No.21, the plurality of first patterns 101 serve as touch driving electrodes for sensing a touch of an object, as stylus driving electrodes for driving a stylus, and as stylus sensing electrodes for sensing a stylus signal. The plurality of third patterns 103 serve as touch sensing electrodes for sensing a touch of an object, as stylus driving electrodes for driving a stylus, and as stylus sensing electrodes for sensing a stylus signal. The plurality of second patterns 102 and the plurality of fourth patterns 104 are electrically floating.

In the case of No.21, since the plurality of first patterns 101 and 3 rd patterns 103 are used as the stylus driving electrodes, the size of the upload signal is relatively small. Since the plurality of first patterns 101 and the plurality of third patterns 103 are used as stylus sensing electrodes, the magnitude of the download signal is relatively small. Also, since the plurality of first patterns 101 are used as the stylus driving electrode and the stylus sensing electrode and the plurality of third patterns 103 are used as the stylus driving electrode and the stylus sensing electrode, no additional channels for driving and sensing of the stylus are required.

The nos.1, 5, 9, 25, 29 in the above < table 2> combinations nos.1 to 32 are driven (driving) as 'there' and sensed (sensing) as 'none' in the column of 'stylus additional channel'. The nos.1, 5, 9, 25, 29 use a plurality of first patterns 101 and third patterns 103 for sensing the stylus, and use a plurality of second patterns 102 and/or fourth patterns 104 for driving the stylus. When the stylus pen is driven, it may be somewhat difficult to form a magnetic field for resonating the stylus pen even with the plurality of second patterns 102 and/or the fourth patterns 104, and thus one end of two or more adjacent second patterns may be electrically connected. One end of the adjacent two or more fourth patterns may be connected as well. With the above configuration, there is an advantage in that additional channels for driving the stylus can be reduced.

Fig. 22 to 26 are schematic diagrams showing a part of the above < table 2> in a plurality of combinations.

Fig. 27 is a schematic view of a touch input device according to another embodiment of the invention.

Referring to fig. 27, a touch input device according to another embodiment of the present invention includes a sensor part 100 'and a control part 500'.

The sensor portion 100' includes a plurality of patterns. The plurality of patterns may include a 1 st pattern 101a, a 1 st pattern 101b, a 2 nd pattern 102a, a 2 nd pattern 102b, a third pattern 103, and a fourth pattern 104. The third pattern 103 and the fourth pattern 104 have the same configuration as the third pattern 103 and the fourth pattern 104 of the sensor unit 100 shown in fig. 16, and therefore, the description thereof will be omitted.

The 1 st a pattern 101a has a shape extending along a first direction (or long axis).

The 1 st a pattern 101a may include an inverted triangle pattern part, a triangle pattern part, and a connection pattern part connecting the inverted triangle pattern part and the triangle pattern part.

The 1 st a pattern 101a may have an opening portion in which the 2 nd a pattern 102a is disposed.

The 1 st a pattern 101a may have a structure surrounding the 2 nd a pattern 102 a. The 1 st a pattern 101a is disposed at a predetermined interval from the 2 nd a pattern 102 a. Thereby being electrically insulated from each other.

The 2 nd pattern 102a is disposed adjacent to the 1 st pattern 101 a. For example, the 2 nd pattern 102a may be disposed inside the 1 st pattern 101 a.

The 2a nd pattern 102a may include an inverted triangle pattern part, a triangle pattern part, and a connection pattern part connecting the inverted triangle pattern part and the triangle pattern part.

The 1 b-th pattern 101b has a shape extending along a first direction (or long axis).

The 1 b-th pattern 101b may include an inverted triangle pattern part, a triangle pattern part, and a connection pattern part connecting the inverted triangle pattern part and the triangle pattern part.

The 1 st b pattern 101b may have an opening portion in which the 2 nd b pattern 102b is disposed.

The 1 st b pattern 101b may have a structure surrounding the 2 nd b pattern 102 b. The 1 st b pattern 101b is disposed at a predetermined interval from the 2 nd b pattern 102 b. Thereby being electrically insulated from each other.

The 2 b-th pattern 102b is disposed adjacent to the 1 b-th pattern 101 b. For example, the 2 nd pattern 102b is disposed inside the 1 st pattern 101 b.

The 2 b-th pattern 102b may include an inverted triangle pattern part, a triangle pattern part, and a connection pattern part connecting the inverted triangle pattern part and the triangle pattern part.

The 1 st patterns 101a and the 1 st patterns 101b are alternately arranged along the first direction, the 1 st patterns 101a are electrically connected to each other, and the 1 st patterns 101b are also electrically connected to each other.

The 1 st a pattern 101a located at one end of the plurality of 1 st a patterns 101a is electrically connected to the control part 500'.

The 1 st b pattern 101b located at one end of the plurality of 1 st b patterns 101b is electrically connected to the control part 500'.

The plurality of 2a patterns 102a and the plurality of 2b patterns 102b are alternately arranged along the first direction and electrically connected to each other. The 2 nd patterns 102a and 102b located at one end of the 2 nd patterns 102a and 102b are electrically connected to the control unit 500, and the 2 nd pattern 102a located at the other end is electrically connected to the other 2 nd patterns adjacent thereto. Other 2a patterns adjacent to the 2a pattern 102a at the other end may be grounded.

The 1 st pattern 101a, the 1 st pattern 101b, the 2 nd pattern 102a, and the 2 nd pattern 102b may be disposed on the same layer. The 1 st a pattern 101a, the 1 st b pattern 101b, the 2 nd a pattern 102a, and the 2 nd b pattern 102b may be formed on the same layer using a metal mesh (metal mesh).

The control unit 500' has the same function as the control unit 500 shown in fig. 16.

Fig. 28 is a schematic diagram illustrating a case where the touch input device shown in fig. 27 operates in a touch sensing mode (or 2D sensing mode).

Referring to fig. 27 and 28, in the touch sensing mode, the control part 500 'may electrically connect the driving circuit part for touch sensing to the third pattern 103 of the sensor part 100'. One driving circuit portion may be electrically connected to each of the plurality of third patterns 103.

The control unit 500 'may electrically connect the sensing circuit unit for touch sensing to the 1 st a pattern 101a and the 1 st b pattern 101b of the sensor unit 100'.

In the touch sensing mode, the control part 500' applies a driving signal for touch sensing to the plurality of third patterns 103 and receives sensing signals received from the plurality of 1 st a patterns 101a and 1 st b patterns 101b. The sensing circuit part of the control part 500' electrically connected to the plurality of 1a101a and 1b th patterns 101b may output capacitance variation information included in the inputted sensing signal to a predetermined voltage value. The control part 500' may process the output voltage value to detect the touch position. Wherein, the control part 500' may cancel the display noise and the LGM noise by subtracting the sensing signal received from the 1 st b pattern 101b from the sensing signal received from the 1 st a pattern 101 a.

Here, to prevent the capacitive coupling (capacitive coupling) between the third pattern 103 and the fourth pattern 104 from occurring, the control part 500' may control such that the same driving signal is applied to the plurality of third patterns 103 and the plurality of fourth patterns 104. Alternatively, the control section 500' may also control such that the reference potential is applied to the plurality of fourth patterns 104.

Fig. 29 is a schematic view showing a case where the touch input device shown in fig. 27 operates in an antenna driving mode (or a stylus driving mode, or a stylus uploading mode).

Referring to fig. 27 and 29, in the antenna driving mode, the control part 500 'may electrically connect the driving circuit part for antenna driving to the 2 a-th pattern 102a and the 2 b-th pattern 102b of the sensor part 100'.

The control unit 500' can control the driving signals outputted from the driving circuit units connected to the 2a nd and 2b nd patterns 102b of the plurality of patterns 102 a. For example, the control section 500' controls so that a pulse signal of a predetermined frequency is output from the first drive circuit section, controls so that no pulse signal is output from the second drive circuit section, and controls so that a pulse signal opposite to the pulse signal output from the first drive circuit section is output from the third drive circuit section. In this case, a current loop is formed by the 2 nd a pattern 102a and the 2 nd b pattern 102b electrically connected to the first driving circuit portion and the 2 nd a pattern and the 2 nd b pattern electrically connected to the third driving circuit portion. The magnetic field is generated by the formed current loop, and the adjacent stylus can be driven by resonance.

The control unit 500' may control any two driving circuit units among the plurality of driving circuit units electrically connected to the 2 nd and 2b th patterns 102a and 102b to output pulse signals opposite to each other. Therefore, the control unit 500' can be provided with various modifications to the size and position of the current loop. For example, the control part 500' may control such that pulse signals opposite to each other are output from the driving circuit parts electrically connected to the two second patterns around the position of the stylus pen in the case where the position of the stylus pen is detected, and control such that pulse signals opposite to each other are output from the driving circuit parts electrically connected to the two 2 nd a patterns 102a and 2 nd b patterns 102b located at the two-side outermost profiles of the plurality of 2 nd a patterns 102a and 2 nd b patterns 102b in the case where the position of the stylus pen is not detected.

In addition, although not shown in the drawings, the control part 500' may control such that a driving signal is applied to the plurality of 1 st a patterns 101a and 1 st b patterns 101b, or/and the third pattern 103. In this case, there is an advantage in that the total number of channels can be reduced.

Fig. 30 is a schematic diagram illustrating a case where the touch input device shown in fig. 27 operates in a stylus sensing mode (or a stylus download mode).

Referring to fig. 30 and 27, in the stylus sensing mode, the control part 500 'may electrically connect the sensing circuit part for stylus sensing to the 1 st a pattern 101a and the 1 st b pattern 101b and the third pattern 103 of the sensor part 100', respectively.

In the stylus sensing mode, when the stylus is located at an arbitrary position of the sensor unit 100' in the same manner as the principle described with reference to fig. 21, a predetermined signal is output from the stylus, and an induced voltage is generated in the 1 st pattern 101a, the 1 st pattern 101b, the 2 nd pattern 102a, the 2 nd pattern 102b, the third pattern 103, and the fourth pattern 104 by the output signal.

When the stylus pen is located at a position distant from the control unit 500', the induced voltage generates almost no current flows in the 1 st a patterns 101a, but the current flows from the 2 nd a patterns 102a, so that the control unit 500' can detect the position of the stylus pen by the sensing circuit unit electrically connected to the 1 st a patterns 101 a. Wherein the current flowing from the 2 nd pattern 102a into the 1 st pattern 101a is caused by the generation of a potential difference between the 1 st pattern 101a and the 2 nd pattern 102a corresponding to the induced voltage, the generated potential difference causing capacitive coupling between the 1 st pattern 101a and the 2 nd pattern 102 a.

Also, almost no current flows in the 1 st patterns 101b themselves, but since current flows from the 2 nd patterns 102b, the control part 500' can detect the position of the stylus pen through the sensing circuit part electrically connected to the 1 st patterns 101 b.

Also, almost no current flows in the third pattern 103 itself, but since current flows from the fourth pattern 104, the control part 500' can detect the position of the stylus pen through the sensing circuit part electrically connected to the third pattern 103.

In addition, although not shown, the control unit 500' may detect the position of the stylus pen by electrically connecting the sensing circuit unit to the plurality of 2a patterns 102a and 2b patterns 102b, or/and the fourth pattern 104, unlike fig. 30.

The sensor unit 100″ of the touch input device shown in fig. 31 has the same structure as the sensor unit 100″ shown in fig. 27, i.e., the 1 st, 2 nd, 2b nd, third, and fourth patterns. The 1 st pattern 101a located on one side (lower side) of the 1 st patterns 101b electrically connected to each other along the first direction is electrically connected to the control unit 500", and the 1 st pattern 101a located on the other side (upper side) of the 1 st patterns 101a electrically connected to each other along the first direction is electrically connected to the control unit 500". Here, the 1 st b pattern located on the other side (upper side) of the 1 st b patterns 101b electrically connected to each other along the first direction is electrically opened, and the 1 st a pattern 101a located on one side (lower side) of the 1 st a patterns 101a electrically connected to each other along the first direction is electrically opened.

Fig. 32 is a schematic diagram illustrating a case where the touch input device shown in fig. 31 operates in a touch sensing mode (or 2D sensing mode).

The explanation of the touch sensing mode is the same as that described in fig. 28, and thus omitted.

Fig. 33 is a schematic diagram showing a case where the touch input device shown in fig. 31 operates in an antenna driving mode (or a stylus driving mode, or a stylus uploading mode).

The description of the antenna driving mode is the same as that described in fig. 29, and thus omitted.

Fig. 34 is a schematic diagram illustrating a case where the touch input device shown in fig. 31 operates in a stylus sensing mode (or a stylus download mode).

The stylus sensing mode of fig. 34 is different from the stylus sensing mode of fig. 30.

When the stylus pen is driven to come close to an arbitrary position on the sensor unit 100″ and a signal is emitted from the stylus pen, a predetermined signal is output from the stylus pen, and an induced voltage is generated in the 1 st pattern 101a, the 1 st pattern 101b, the 2 nd pattern 102a, the 2 nd pattern 102b, the third pattern 103, and the fourth pattern 104 by the output signal.

When the stylus pen is located at a position distant from the control unit 500', the induced voltage generates, and almost no current flows in the 1 st patterns 101b themselves, but the current flows not only from the 2 nd patterns 102b but also from the 1 st patterns 101a, so that the control unit 500' can detect the position of the stylus pen by the sensing circuit unit electrically connected to the 1 st patterns 101 b. Wherein the current flowing from the 2 nd pattern 102b and the 1 st pattern 101a into the 1 st pattern 101b is caused by a potential difference corresponding to the induced voltage generated between the 1 st pattern 101b and the 2 nd pattern 102b and between the 1 st pattern 101b and the 1 st pattern 101a, and the generated potential difference causes capacitive coupling between the 1 st pattern 101b and the 2 nd pattern 102b and capacitive coupling between the 1 st pattern 101b and the 1 st pattern 101 a.

Among them, the reason why the current flows from the 1 st a pattern 101a into the 1 st b pattern 101b is different from fig. 30 because the current flows relatively much in the plurality of 1 st a patterns 101a themselves. This is because the direction of the conductive traces connected to the 1 st pattern 101a is connected to be opposite to the direction of the conductive traces connected to the 1 st pattern 101 b. In other words, the reason for this is that, in the case where the stylus pen is disposed away from the sensing circuit portion connected to the plurality of 1 b-th patterns 101b, the stylus pen is disposed closer to the sensing circuit portion connected to the plurality of 1 a-th patterns 101 a.

In addition, although not shown, the control part 500″ may detect the position of the stylus pen by electrically connecting the sensing circuit part to the plurality of 2a patterns 102a or 2b patterns 102b or the fourth pattern 104, unlike fig. 34.

Fig. 36 is a partial plan view of a sensor portion 200 according to another embodiment that can replace the sensor portion 100 of fig. 16.

Referring to fig. 36, a sensor part 200 according to another embodiment of the present invention includes a plurality of first patterns and a plurality of second patterns. Hereinafter, the plurality of first patterns are described as the plurality of driving electrodes TX0, TX1, TX2, … …, and the plurality of second patterns are described as the plurality of receiving electrodes RX0, RX1, RX2, … …. Although not shown, the plurality of first electrodes may be the plurality of receiving electrodes RX0, RX1, RX2, and … …, and the plurality of second electrodes may be the plurality of driving electrodes TX0, TX1, TX2, and … ….

The plurality of driving electrodes TX0, TX1, TX2, … … have a form extending along a first direction (or a lateral direction), and the plurality of receiving electrodes RX0, RX1, RX2, … … have a form extending along a second direction (or a vertical direction) perpendicular to the first direction.

A predetermined capacitance is formed between the plurality of driving electrodes TX0, TX1, TX2, … … and the plurality of receiving electrodes RX0, RX1, RX2, … …, particularly at their intersections. This capacitance changes when a touch input occurs at that location or its periphery. The amount of change in capacitance can be detected from signals output from the plurality of receiving electrodes RX0, RX1, RX2, … … to detect whether a touch or not and a touch input.

The plurality of driving electrodes TX0, TX1, TX2, … … shown in fig. 36 each include a first driving pattern portion 211, a second driving pattern portion 213, and a connection pattern 215. Among them, the first driving pattern portion 211 may be named as a 1 st-1 st pattern portion, the second driving pattern portion 213 may be named as a 1 st-2 nd pattern portion, and the connection pattern 215 may be named as a connection pattern portion.

The first driving pattern portion 211 has a diamond (diamond) shape or a diamond shape, and has an opening (O) with an inner opening. The opening (O) has a diamond shape or a diamond shape corresponding to the external shape of the first driving pattern portion 211. The first driving pattern portion 211 may have a diamond or diamond-shaped belt shape through the opening (O). The first driving pattern portion 211 is shown as diamond or diamond shape, but this is only an example, and the first driving pattern portion 211 may have a polygonal shape, a rectangular shape, or the like, for example.

The second driving pattern portion 213 is disposed in the opening (O) of the first driving pattern portion 211.

The second driving pattern part 213 is disposed adjacent to the first driving pattern part 211. The second driving pattern part 213 may have a diamond shape or a diamond shape. The appearance shape of the second driving pattern part 213 has a shape corresponding to the first driving pattern part 211. The second driving pattern part 213 may not have an opening formed therein unlike the first driving pattern part 211.

The first driving pattern part 211 and the second driving pattern part 213 are disposed at a predetermined interval from each other.

The plurality of first driving pattern portions 211 in which the second driving pattern portions 213 are disposed are arranged along the first direction (or the horizontal direction). The connection pattern 215 disposed between the plurality of first driving pattern portions 211 electrically connects the plurality of first driving pattern portions 211 to each other.

The connection pattern 215 connects two adjacent first driving pattern parts 211. One end is connected to the first driving pattern portion 211 disposed on one side, and the other end is connected to the first driving pattern portion disposed on the other side. The connection pattern 215 may have a bar shape, but is not limited thereto, and two adjacent first driving pattern parts 211 may be connected in various shapes.

At least a portion of the plurality of first driving pattern portions 211, at least a portion of the plurality of second driving pattern portions 213, and at least a portion of the plurality of connection patterns 215 are disposed on the same layer. For example, the plurality of first driving pattern portions 211, the plurality of second driving pattern portions 213, and the plurality of connection patterns 215 may be disposed together in the same layer. The plurality of first driving pattern portions 211, the plurality of second driving pattern portions 213, and the plurality of connection patterns 215 may be formed of the same material. For example, the plurality of first driving pattern parts 211, the plurality of second driving pattern parts 213, and the plurality of connection patterns 215 may be formed of a metal mesh (metal mesh). The metal mesh may be patterned accordingly according to the shapes of the first driving pattern parts 211, the second driving pattern parts 213, and the connection patterns 215 to form the driving electrodes TX0, TX1, TX2, … ….

In addition, although the second driving pattern portion 213 is shown in fig. 36 as being disposed in the opening O in the first driving pattern portion 211, the driving electrodes of the present invention are not limited thereto, and the first driving pattern portion 211 and the second driving pattern portion 213 may have shapes other than diamond or diamond-shaped shapes. The first driving pattern part 211 and the second driving pattern part 213 may be combined with each other in various shapes to constitute one driving electrode.

The second driving pattern portions 213 of the driving electrodes TX0, TX1, TX2 are electrically connected. For example, the second driving pattern portions 213 of the respective driving electrodes TX0, TX1, TX2 may be electrically connected to each other through a bridge and a via.

The first driving pattern part 211 located at the other side edge of the first driving pattern part 211 of each driving electrode TX0, TX1, TX2 is electrically opened, and the second driving pattern parts 213 located at the other side edge of the second driving pattern part 213 of each driving electrode TX0, TX1, TX2 are electrically connected to each other. For example, the second driving pattern portions 213 of the respective driving electrodes TX0, TX1, TX2 may be electrically connected to each other through a bridge and a via. The other side is the side farthest from the control unit 500 in fig. 16 of the first driving pattern portion 211 and the second driving pattern portion 213 of each of the driving electrodes TX0, TX1, TX 2.

Each of the plurality of receiving electrodes RX0, RX1, RX2 includes a first receiving pattern part 231 and a second pattern part 233. The first receiving pattern portion 231 may be named as a 2-1 th pattern portion, and the second receiving pattern portion 233 may be named as a 2-2 nd pattern portion.

The first and second receiving pattern parts 231 and 233 have the same shape as the first and second driving pattern parts 211 and 213, and thus detailed descriptions thereof are omitted.

The plurality of first receiving pattern portions 231 are arranged along the second direction (or the vertical direction). The plurality of first receiving pattern parts 231 are electrically connected to each other. For example, the plurality of first receiving pattern parts 231 may be electrically connected through a bridge and a via hole.

The plurality of second receiving pattern portions 233 are respectively arranged inside the first receiving pattern portions 231 along the second direction (or the vertical direction).

The first receiving pattern portions 231 and the second receiving pattern portions 233 may be disposed on the same layer as the first driving pattern portions 211, the second driving pattern portions 213, and the connection patterns 215.

The plurality of first receiving pattern portions 231 and the plurality of second receiving pattern portions 233 may be formed of the same material. For example, the plurality of first receiving pattern parts 231 and the plurality of second receiving pattern parts 233 may be formed of a metal mesh (mesh). The metal mesh may be patterned accordingly according to the shapes of the first and second receiving pattern portions 231 and 233 to form the receiving electrodes RX0, RX1, and RX2.

Therefore, the 1 st-2 st pattern portions of the 1 st-2 nd pattern portions located at the first side or/and the second side end portion may be exposed to the outside.

The 1 st-2 st pattern portions of the 1 st-2 nd pattern portions located at the second side end portion are electrically connected to each other by a connection pattern without a via hole. Wherein the connection pattern may be a conductive trace.

In the sensor portion 200″, the 2 nd-1 st pattern portions of the 2 nd-1 st pattern portions located on the first side and/or the second side end portion have a shape that is open in the second direction (or the vertical direction). Therefore, the 2-2 nd pattern portions of the plurality of 2 nd pattern portions located at the first side or/and the second side end portion may be exposed to the outside.

The plurality of 2 nd-2 nd pattern portions located at the second side end portion of the plurality of 2 nd pattern portions are electrically connected to each other by a connection pattern without a via hole.

Compared with fig. 37, there is an advantage in that the plurality of 2-2 nd pattern portions located at the second side end portion of the plurality of 2 nd pattern portions are not connected by vias and are arranged at the same layer as the connection pattern.

The modification shown in fig. 38 can also be applied directly to the sensor section shown in fig. 36.

As shown in fig. 17 to 21, the sensor unit 200″ shown in fig. 38 may be driven in any one of a touch sensing mode, an antenna driving mode, and a stylus sensing mode under the control of the control unit 500. Specifically, in the touch sensing mode, the control part 500 may control such that a touch driving signal is applied to ATX1, ATX2, ATX3, and a touch receiving signal is received from ARX1, ARX2, ARX3 to sense a touch position.

Fig. 39 is a schematic diagram showing another modification of the sensor unit 100 shown in fig. 16.

Referring to fig. 39, the structures of the main pattern portions of the first to fourth pattern portions 101', 102', 103', 104' are different from those of fig. 16.

In fig. 39, the outline of the second pattern portion 102 'or the fourth pattern portion 104' is formed in a concave-convex structure, and the opening of the first pattern portion 101 'or the fourth pattern portion 104' has a shape corresponding to the outline structure of the second pattern portion 102 'or the fourth pattern portion 104'.

This structure has the advantage that the value of the mutual capacitance Cm between the first pattern portion 101 'and the second pattern portion 102' in the same layer can be increased, and the value of the mutual capacitance Cm between the third pattern portion 103 'and the fourth pattern portion 104' in another same layer can be increased. The voltage value output from the sensing circuit part of the control part 500 in the stylus sensing mode can be increased so that the mutual capacitance Cm can be increased. The stylus sensing sensitivity can be improved.

The modification shown in fig. 39 may be applied directly to the sensor unit according to the above-described embodiments.

Fig. 40 shows still another modification of the sensor unit 100 shown in fig. 16.

The sensor portion 100″ shown in fig. 40 further includes a plurality of fifth patterns 105 and a plurality of sixth patterns 106 as compared to the sensor portion 100 shown in fig. 16.

The plurality of fifth patterns 105 are arranged on the same layer (second layer) as the plurality of first patterns 101, and are arranged along the first direction and the second direction.

The fifth pattern 105 is electrically connected to the fourth pattern 104 disposed on the other layer (first layer) through a via hole.

The plurality of fifth patterns 105 may form a mutual capacitance Cm in a vertical direction with the plurality of third patterns 103. Further, since the fifth pattern 105 is electrically connected to the fourth pattern 104 inside the third pattern 103, the third pattern 103 can form a mutual capacitance Cm with not only the fourth pattern 104 but also the fifth pattern 105.

The plurality of sixth patterns 106 and the plurality of third patterns 103 are arranged on the same layer (first layer), and are arranged in the first direction and the second direction.

The sixth pattern 106 is electrically connected to the second pattern 102 disposed on the other layer (second layer) through a via hole.

The plurality of sixth patterns 106 may form a mutual capacitance Cm in a vertical direction with the plurality of first patterns 101. Further, since the sixth pattern 106 is electrically connected to the second pattern 102 inside the first pattern 101, the first pattern 101 can form a mutual capacitance Cm with not only the second pattern 102 but also the sixth pattern 105.

As described above, the sensor unit 100″ shown in fig. 40 has an advantage that mutual capacitances in the horizontal and vertical directions of the first pattern 101 can be formed and mutual capacitances in the horizontal and vertical directions of the third pattern 103 can be formed. Therefore, the voltage value output from the sensing circuit part of the control part 500 in the stylus sensing mode can be increased, and the stylus sensing sensitivity can be improved.

The modification shown in fig. 40 may be applied directly to the sensor unit of the above-described embodiments.

Fig. 41 shows still another modification of the sensor unit 100 shown in fig. 16.

The sensor portion 100 '"shown in fig. 41 is configured such that a part of the second pattern 102' and the remaining part thereof are disposed in different layers from each other, compared to the sensor portion 100 shown in fig. 16. Specifically, the second pattern 102' includes a plurality of main pattern portions and a connection pattern portion connecting two adjacent main pattern portions among the plurality of main pattern portions, and the plurality of main pattern portions of the second pattern 102' and the plurality of connection pattern portions of the second pattern 102' are arranged in different layers from each other.

The plurality of main pattern portions of the second pattern 102 'are arranged on the same layer as the third pattern 103 and the fourth pattern 104, and the plurality of connection pattern portions of the second pattern 102' are arranged on the same layer as the first pattern 101 as shown in fig. 16.

The sensor unit 100' "shown in fig. 41 may be driven in the touch sensing mode, the antenna driving mode, and the stylus sensing mode by the control unit 500, as in the sensor unit 100 shown in fig. 16. Further, a plurality of combinations of < table 2> may be applied to the sensor portion 100' "of fig. 41. The sensor section 100' "of fig. 41 can be driven in any one of a touch sensing mode, an antenna driving mode, and a stylus sensing mode in various manners by the control section 500.

Fig. 42 shows still another modification of the sensor unit 100 shown in fig. 16.

The sensor portion 100 ' "shown in fig. 42 is different from the sensor portion 100 '" shown in fig. 41 in that a part of the fourth pattern 104' and the remaining part are located in different layers from each other. Specifically, the fourth pattern 104' includes a plurality of main pattern portions and a connection pattern portion connecting two adjacent main pattern portions among the plurality of main pattern portions, and the plurality of main pattern portions of the fourth pattern 104' and the plurality of connection pattern portions of the fourth pattern 104' are disposed in different layers from each other. The plurality of main pattern portions of the fourth pattern 104' are arranged on the same layer as the first pattern 101, and the plurality of connection pattern portions of the fourth pattern 104' are arranged on the same layer as the plurality of main pattern portions of the second pattern 102' and the third pattern 103.

In summary, in the sensor portion 100″ shown in fig. 42, the plurality of connection pattern portions of the first pattern 101 and the second pattern 102', the plurality of main pattern portions of the fourth pattern 104' are arranged in the first layer, and the plurality of connection pattern portions of the third pattern 103 and the fourth pattern 104', and the plurality of main pattern portions of the second pattern 102' are arranged in the second layer. Wherein the first layer and the second layer are different layers from each other, and any one of the layers may be disposed on the other layer with respect to the positional relationship.

The sensor unit 100 "shown in fig. 42 may be driven in the touch sensing mode, the antenna driving mode, and the stylus sensing mode by the control unit 500, similarly to the sensor unit 100 shown in fig. 16. Further, a plurality of combinations of < table 2> may be applied to the sensor portion 100"", fig. 42. The sensor section 100"" of fig. 42 can be driven in any one of a touch sensing mode, an antenna driving mode, and a stylus sensing mode in various ways by the control section 500.

Fig. 43 is a further modification of the sensor unit 100 shown in fig. 16.

The sensor portion 100""' shown in fig. 43 is obtained by deforming the sensor portion 100"" "shown in fig. 42. The sensor portion 100""' shown in fig. 43 is different from the sensor portion 100"", shown in fig. 42, in the second pattern 102 "and the fourth pattern 104".

Specifically, the second pattern 102 "includes a plurality of main pattern portions 102a" and a plurality of connection pattern portions 102b ', and has a form of a main pattern portion of the second pattern 102' in which the main pattern portion 102a "has a larger size than the sensor portion 100" ", shown in fig. 42. The size of the main pattern portion 102a″ may have a size and shape corresponding to the main pattern portion of the first pattern 101.

The fourth pattern 104 "includes a plurality of main pattern portions 104a" and a plurality of connection pattern portions 104b ', and has a main pattern portion of a fourth pattern 104' having a larger size than the sensor portion 100 "shown in fig. 42. The size of the main pattern portion 104a″ may have a size and shape corresponding to those of the third pattern 103.

The main pattern portion 102a "of the second pattern 102" has a larger size than the main pattern portion of the second pattern 102' of fig. 42, and thus the corresponding area to the first pattern 101 increases, and thus the mutual capacitance Cm between the second pattern 102 "and the first pattern 101 can be further improved. Therefore, the sensing sensitivity of the stylus can be further improved in the stylus sensing mode.

Further, since the main pattern portion 104a "of the fourth pattern 104" has a larger size than the main pattern portion of the fourth pattern 104' of fig. 42, the area corresponding to the third pattern 103 increases, and therefore the mutual capacitance Cm between the fourth pattern 104 "and the third pattern 104 can be further improved. Therefore, the stylus sensing sensitivity in the stylus sensing mode can be further improved.

Fig. 44 is a schematic diagram showing a modification of the sensor unit 100 shown in fig. 16.

The other ends of the plurality of second patterns 102 and the other ends of the plurality of fourth patterns 104 of the sensor portion 100 shown in fig. 44 are electrically connected to each other as compared with the sensor portion 100 shown in fig. 16.

With this configuration, the sensor unit 100' is configured toThe sensing mode is driven by electrically connecting the plurality of second patterns 102 to one fourth pattern 104 in addition to the other fourth patterns, and thus has an advantage of further reducing the impedance.

The sensor unit 100"" "shown in fig. 44 may be driven in the touch sensing mode, the antenna driving mode, and the stylus sensing mode by the control unit 500, similarly to the sensor unit 100 shown in fig. 16. Further, a plurality of combinations of < table 2> may be applied to the sensor unit 100"" "of fig. 44. The sensor section 100"" of fig. 44 can be driven in any one of a touch sensing mode, an antenna driving mode, and a stylus sensing mode in various ways by the control section 500.

Fig. 45 shows still another modification of the sensor unit 100 shown in fig. 16.

The sensor portion 100"" "shown in fig. 45 is different from the sensor portion 100 shown in fig. 16 in that the second pattern 102 'and the fourth pattern 104', further includes a plurality of fifth patterns 105 'and a plurality of sixth patterns 106', and further includes a capacitor cap electrically connected to the fifth patterns 105 'and the sixth patterns 106'. The other components are the same, and therefore, the difference will be described in detail below.

The second pattern 102' may be a bar pattern disposed inside the first pattern 101 and extending in the second direction. Wherein the second pattern 102' may have a certain width. The second pattern 102' is arranged on the same layer (second layer) as the first pattern 101.

The fourth pattern 104' may be a stripe (bar) pattern disposed inside the third pattern 103 and extending in the first direction. Wherein the fourth pattern 104' may have a certain width. The fourth pattern 104' is arranged on the same layer (first layer) as the third pattern 103.

The plurality of fifth patterns 105' are arranged on the same layer (second layer) as the plurality of first patterns 101, and are arranged in the first direction and the second direction. The plurality of fifth patterns 105' may be arranged in plurality at respective gaps of the plurality of first patterns 101.

Each of the fifth patterns 105' includes a shape corresponding to and overlapping the main pattern portion of the third pattern 103 disposed in the other layer (first layer). The fifth pattern 105 'is electrically connected to the fourth pattern 104' disposed on the other layer (first layer) through a via hole.

The fifth patterns 105' electrically connected to one fourth pattern 104' among the plurality of fifth patterns 105' are arranged along the second direction. Among the plurality of fifth patterns 105 'arranged along the second direction, a predetermined capacitor cap is connected to the fifth pattern 105' arranged at the other side edge. And, the capacitor cap may be grounded. Among the plurality of fifth patterns 105 'arranged along the second direction, the fifth pattern 105' arranged at the other side edge is a pattern electrically connected farthest from the control unit 500 shown in fig. 16. Although not otherwise shown, the capacitor cap may be connected between the fifth pattern 105' and ELVSS of a display panel (not shown). The capacitor cap may have one end connected to the fifth pattern 105', and the other end connected to another layer (first layer) on which the third pattern 103, the fourth pattern 104', and the sixth pattern 106' are arranged.

The plurality of fifth patterns 105' may form a mutual capacitance Cm in a vertical direction with the plurality of third patterns 103. Further, since the fifth pattern 105 'is electrically connected to the fourth pattern 104' inside the third pattern 103, the third pattern 103 can form a mutual capacitance Cm with not only the fourth pattern 104 'but also the fifth pattern 105'.

The plurality of sixth patterns 106' are arranged on the same layer (first layer) as the plurality of third patterns 103, and are arranged in the first direction and the second direction. The plurality of sixth patterns 106' may be arranged in plurality between the plurality of third patterns 103, respectively.

Each sixth pattern 106' includes a shape corresponding to and overlapping the main pattern portion of the first pattern 101 arranged in the other layer (second layer). The sixth pattern 106 'is electrically connected to the second pattern 102' arranged in another layer (second layer) through a via hole.

The plurality of sixth patterns 106 'electrically connected to one of the second patterns 102' are arranged along the first direction. Among the plurality of sixth patterns 106 'arranged along the first direction, a predetermined capacitor cap is connected to the sixth pattern 106' arranged on the other side edge. And, the capacitor cap may be grounded. Among the plurality of sixth patterns 106 'arranged along the first direction, the sixth pattern 106' arranged at the other side edge is a pattern electrically connected farthest from the control unit 500 shown in fig. 16. Although not otherwise shown, the capacitor cap may be connected between the sixth pattern 106' and ELVSS of the display panel (not shown). The capacitor cap may have one end connected to the sixth pattern 106', and the other end connected to another layer (second layer) where the first pattern 101, the second pattern 102', and the fifth pattern 105' are arranged.

The plurality of sixth patterns 106' may form a mutual capacitance Cm in a vertical direction with the plurality of first patterns 101. Further, since the sixth pattern 106 'is electrically connected to the second pattern 102' inside the first pattern 101, the first pattern 101 can form a mutual capacitance Cm with not only the second pattern 102 'but also the sixth pattern 106'.

As described above, the sensor unit 100"" "shown in fig. 45 has an advantage that mutual capacitance in the horizontal direction and the vertical direction of the first pattern 101 can be formed, and mutual capacitance in the horizontal direction and the vertical direction of the third pattern 103 can be formed. Therefore, the voltage value output from the sensing circuit part of the control part 500 in the stylus sensing mode can be increased, and thus the stylus sensing sensitivity can be improved.

Further, since the second pattern 102' and the fourth pattern 104' are different from the second pattern 102 and the fourth pattern 104 of the sensor portion 100 in fig. 16 and do not have the diamond-shaped main pattern portion, the display panel is positioned below the sensor portion 100"" "', and thus, there is an advantage that the visibility can be further improved as compared with the sensor portion 100 in fig. 16.

The sensor unit 100 ""' shown in fig. 45 can be driven in the touch sensing mode, the antenna driving mode, and the stylus sensing mode by the control unit 500, as in the sensor unit 100 shown in fig. 16. Further, a plurality of combinations of < table 2> can be applied to the sensor unit 100"" "" of fig. 45. The sensor section 100"" "of fig. 45 can be driven in any one of the touch sensing mode, the antenna driving mode, and the stylus sensing mode in various ways by the control section 500.

Although not shown in the drawings, the fifth pattern 105 'and the sixth pattern 106' may be omitted, and the capacitor cap may be electrically connected to the other ends of the plurality of second patterns 102 and the fourth pattern 104, respectively. In the sensor unit according to the above-described embodiments, the other ends of the second patterns and the fourth patterns (the other ends of the second driving pattern units 213 and the second receiving pattern units 233 in the case of fig. 36 and 37) may not be connected to each other, and the other ends thereof may be connected to a capacitor.

Fig. 46 shows still another modification of the sensor unit 100 shown in fig. 16.

In the case of the sensor unit 100 of fig. 16, when the stylus 50 is positioned on the right side edge (or the left side edge) of the sensor unit 100, it is difficult to supply a sufficient magnetic field signal to the stylus 50, and thus there is a possibility that the signal emitted from the stylus 50 cannot be sufficiently increased. To solve such a problem, the sensor portion 100"" "shown in fig. 46 further includes a first trace t1 and a second trace t2 on the basis of the sensor portion 100 shown in fig. 16.

The first trace t1 and the second trace t2 are directly connected to the conductive trace to electrically connected to the other ends of the plurality of second patterns 102, and are disposed in an inactive region outside the active region (or touch region) tp as a touch input device. At least a portion of the conductive trace to may be disposed outside the activation region tp. The activation region tp is a region where an object, such as a finger or a stylus 50, can directly touch, and the non-activation region is disposed around the activation region tp. The inactive zone may be, for example, a bezel (bezel) zone.

Specifically, the first trace t1 is disposed in an inactive area outside the active area tp, one end is directly connected to the conductive trace to, and the other end is connectable to the driving circuit portion of the control portion 500 through the switch sw in any one of the touch driving mode, the touch sensing mode, the antenna driving mode, and the stylus sensing mode.

The second trace t2 is disposed in the inactive region outside the active region tp, and has one end directly connected to the conductive trace to and the other end connectable to the driving circuit portion of the control portion 500 through the switch sw in the antenna driving mode.

The first trace t1 may be disposed in the inactive region surrounding one of the left and right sides of the active region tp, and the second trace t2 may be disposed in the inactive region surrounding the other side of the active region tp.

When the sensor unit 100"" "" is operated in the antenna driving mode as shown in fig. 18, the first trace t1 and the second trace t2 can provide a sufficient magnetic field signal to the stylus pen 50 even if the stylus pen 50 is positioned at one side edge of the activation region tp. Therefore, in the touch input device including the sensor portion 100"" "shown in fig. 46, even if the stylus pen 50 is located at an arbitrary position of the activation region tp, the stylus pen 50 can obtain a sufficient magnetic field signal and emit a sufficient signal.

The driving method shown in fig. 19 (a) to (c) can be directly applied to each of the first trace t1 and the second trace t2 of the sensor portion 100"" "shown in fig. 46 as one channel in fig. 19.

The sensor unit 100"" "shown in fig. 46 is also drivable in the touch sensing mode, the antenna driving mode, and the stylus sensing mode by the control unit 500, as in the sensor unit 100 shown in fig. 16. Further, a plurality of combinations of < table 2> may be applied to the sensor portion 100"" "" of fig. 46. The sensor section 100"" "of fig. 46 can be driven in any one of the touch sensing mode, the antenna driving mode, and the stylus sensing mode in various ways by the control section 500.

Fig. 47 is a schematic diagram for explaining a first modification of the fifth pattern 105 shown in fig. 40.

Referring to fig. 47, the fifth pattern 105' is disposed on a layer other than the layers on which the third pattern 103 and the fourth pattern 104 are disposed.

The fifth pattern 105' may have a shape corresponding to the third pattern 103. For example, the fifth pattern 105' may have a diamond shape and may have an opening portion therein.

A part of the fifth pattern 105' is arranged to overlap the third pattern 103 in the upper and lower directions, and the other part may be arranged to overlap the fourth pattern 104 in the upper and lower directions. For example, an outer edge portion of the fifth pattern 105' may overlap an inner edge portion of the third pattern 103 disposed at the other layer. The inner edge portion of the fifth pattern 105' may overlap the outer edge portion of the fourth pattern 104 disposed at the other layer.

The fifth pattern 105' is electrically connected to the fourth pattern 104 disposed on the other layer through the conductive via v. The number of the via holes v may be plural, and may be disposed at an outer edge portion of the fourth pattern 104.

Such a fifth pattern 105' may form a mutual capacitance Cm in a vertical direction with the third pattern 103 disposed on the other layer. Further, since the fifth pattern 105 'is electrically connected to the fourth pattern 104 inside the third pattern 103 through the via hole v, the third pattern 103 can form a mutual capacitance cc_tx with the fourth pattern 104 disposed on the same layer and the fifth pattern 105' disposed on another layer.

Although not otherwise illustrated, the sixth pattern 106 shown in fig. 40 may have the same shape as the fifth pattern 105' shown in fig. 47. Here, an outer edge portion of the sixth pattern (not shown) may overlap an inner edge portion of the first pattern 101 disposed on the other layer, and an inner edge portion of the sixth pattern (not shown) may overlap an outer edge portion of the second pattern 102 disposed on the other layer. The sixth pattern (not shown) may be electrically connected to the second pattern 102 disposed on the other layer through a conductive via. Similarly, such a sixth pattern (not shown) may form a mutual capacitance in a vertical direction with the first pattern 101, and since the sixth pattern (not shown) is electrically connected to the second pattern 102 inside the first pattern 101, the first pattern 101 can form a mutual capacitance Cm with the second pattern 102 and the sixth pattern (not shown).

As described above, the sensor portion including the modification of the fifth pattern 105' shown in fig. 47 can form mutual capacitances in the horizontal and vertical directions of the third pattern 103, and the sensor portion including the modification of the sixth pattern (not shown) also has an advantage that mutual capacitances in the horizontal and vertical directions of the first pattern 101 can be formed. Therefore, the voltage value output from the sensing circuit portion of the controller of the control portion in the stylus sensing mode can be increased, and the stylus sensing sensitivity can be increased.

Fig. 48 is a modification of fig. 47.

Fig. 47 shows that the fifth pattern 105 'is disposed under the third pattern 103 and the fourth pattern 103, and fig. 37 shows that the fifth pattern 105' is disposed on the third pattern 103 and the fourth pattern 104 in contrast.

Fig. 49 is a schematic diagram for explaining a modification of the fifth pattern 105' shown in fig. 47.

Referring to fig. 49, the fifth pattern 105″ is identical in shape and position to the fifth pattern 105' shown in fig. 47. The fifth pattern 105″ is different from the fifth pattern 105' shown in fig. 47 in that the fifth pattern 105″ is electrically connected to the third pattern 103 disposed in another layer through the conductive via v. The via hole v is disposed at an inner edge portion of the third pattern 103.

Since the fifth pattern 105 "is electrically connected to the third pattern 103 disposed in the other layer direction, the fourth pattern 104 and the fifth pattern 105" can form a mutual capacitance cc_tx in the vertical direction.

The sensor portion including the modification of the fifth pattern 105″ shown in fig. 49 also has an advantage that mutual capacitance in the horizontal direction and the vertical direction can be formed.

Fig. 50 is a modification of fig. 49.

Fig. 49 shows that the fifth pattern 105 "is disposed under the third pattern 103 and the fourth pattern 104, and fig. 50 shows that the fifth pattern 105" is disposed on the third pattern and the fourth pattern 103, 104 in contrast.

For example, the inner edge portion of the third pattern 103 may be configured to overlap the outer edge portion of the fourth pattern 104 in the vertical direction. In fig. 51, the third pattern 103 is disposed on the fourth pattern 104, and fig. 52 shows that the third pattern 103 is disposed on the lower portion of the fourth pattern 104.

The sensor portion including the third pattern 103 and the fourth pattern 104 shown in fig. 51 and 52 may form the mutual capacitance cc_tx in a vertical direction instead of a horizontal direction. Although not shown in the drawings, the first pattern 101 and the second pattern 102 shown in fig. 41 and 42 may have structures shown in fig. 51 and 52.
