Description of the Invention: - Technical Field of the Invention The present invention relates to a touch screen and a display device, and more particularly to a touch screen using a transparent conductor of carbon nanotubes and a display device using the same. [Prior Art] In recent years, the development of high-performance and diversified devices such as mobile phones and touch navigation systems, such as mobile phones and touch navigation systems, has been installed in front of liquid crystal display devices. The number of electronic devices has gradually increased. The user of such an electronic device operates the display content of the display device located on the back surface of the touch panel by visually checking the touch panel while pressing the touch panel with a finger or a pen. Thereby, the functions of the electronic device can be operated. = The working principle of the touch screen is different from that of the transmission medium f. The previous types are resistive, capacitive, infrared and surface acoustic wave. Among them, the capacitive touch force is widely used (Li Shuben, I Qingdi 1; 匕 =: Vol. 15, P62 (1995)) 〇思,, optoelectronic technology, the capacitive touch type eight-point capacitor in the prior art Two types of touch screens. More, :;::"1 capacitive touch screen and - sensing layer. The driving center ‘= touch screen includes a driving layer between the driving layer and the driving layer—a spacer layer, 22, and a line. This feeling. The sensing layer includes a plurality of spacers I, and sensing lines spaced apart from each other. The above drive line and sense 6 1355104 should be in different planes and intersected. The drive layer is connected to a drive circuit and supplied with a voltage from a plurality of drives 2 in the drive layer by the drive circuit. The sensing line intersects the sensing line to form an inductive valley. The upper layer is connected to a capacitive sensing element that senses a change in capacitance of a plurality of sensing lines on the sensing layer. In the capacitive touch screen, the glass substrate and the spacer layer are made of steel mother glass: the driving wire and the sensing I (4) are the through-feed wires, and (4) the conductive material mold (4) is formed as 'indium tin oxide (IT0) or 锑Tin oxide (ΑΤΟ) and the like. In addition, a gap is formed in the gap between the transparent wires, and the material of the filling layer has a refractive index and a transmittance close to or close to the material f layer and the wire material, thereby making the touch screen transparent and transparent. The difference is minimal. ^ When a touch object such as a finger touches the surface of the touch screen, a capacitive capacitance is formed between the touch object such as a human body electric field and one or more nodes in the touch panel contact area. For high-frequency currents, the capacitance is a direct conductor, and the touch of a finger or the like touches one or more nodes in the contact area, and a small current causes a sense capacitance at one or more nodes. According to the variation, the capacitive sensing component measures the change of the sensing capacitance at the one or more nodes, and records the position coordinates of the one or more nodes, thereby implementing multi-touch. Therefore, the transparent wires are necessary for the touch screen system. In the prior art, the transparent wires are usually formed by using ΙΤΟ wires. The τ ◦ wires are mainly prepared by deposition or etching, and a high vacuum environment and heating are required in the preparation process. To the fan ~ 3GGt, so that the preparation cost of the tantalum wire is higher. Further, the wire formed by bismuth has the disadvantages of mechanical and chemical resistance, which is not good for use, and cannot be bent. In view of this, it is necessary to provide a touch panel having high resolution, high precision, and durability, and a display device using the touch panel.

The carbon nanotube array and the above substrate area are basically In the present embodiment, the anti-source gas of the present invention may be selected from the chemical properties of acetylene, ethylene, and a hospital. The preferred carbon source gas in this embodiment is B; the shielding gas is nitrogen or an inert gas. The preferred shielding gas of the embodiment is argon gas. It is understandable. The carbon nanotube array provided in this embodiment is not limited to the above preparation method, and may be a graphite electrode constant current arc discharge deposition method, a laser burst deposition method, etc. Step 2: using a stretching tool from a carbon nanotube array The mid-drawing obtains a carbon nanotube film or a nano carbon tube long line, which specifically comprises the following steps: (a) selecting a plurality of carbon nanotube segments of a certain width from the above-mentioned carbon nanotube array, which is preferred in this embodiment. In order to take a plurality of carbon nanotubes in a carbon nanotube array with a pair of dice, a plurality of carbon nanotube segments of a certain width are selected to be 彳b) 13 1355104 at a 疋 speed along a substantially perpendicular to the hem half #μ奈奈a carbon nanotube, which stretches the long length of the plurality of tubes in the direction of forming the array. Only the nano carbon official film or the nano carbon is gradually separated from the substrate in the stretching direction during the stretching process; ^Nu: The fragment is used for pulling force, and the selected ^cut f / Van der Waals force is continuously pulled out end to end; thus: 2: carbon nanotubes are long carbon tubes. The nano-carbon nanotube film or the nano-carbon nanotube film or the long-term carbon nanotube tube is formed in a preferred orientation. The arrangement of the nano carbon tube film or the carbon nanotubes in the nano tube is substantially parallel to the stretching direction t to obtain the nano carbon tube thin_nano carbon tube long line method is simple and rapid suitable for industrial application. In the early embodiment, the width of the nanotube film or the length of the carbon nanotube long line is related to the width of the stretching tool, and the length of the carbon nanotube or the carbon nanotube long line is not limited. According to the actual demand, in this embodiment, a 4-inch substrate is used to grow a super-sequential carbon nanotube array, and the width of the carbon nanotube film or the carbon long line can be i mm ~! cm, the nanometer. The dry film f of the carbon tube film is 0.5 nm to 1 μm. When the carbon nanotube in the carbon nanotube film is an early-walled carbon nanotube, the diameter of the single-walled carbon nanotube is 〇5奈When the carbon nanotubes in the carbon nanotube film are double-walled carbon nanotubes, the diameter of the double-walled carbon nanotubes is 1 〇 nanometer ~ 5 〇 nanometer. When the film When the carbon nanotube in the middle is a multi-walled carbon nanotube, the multi-walled carbon nanotube is directly controlled to be 1.5 nm to 50 nm. In the above stretching process, the plurality of carbon nanotubes are segmented. Tensile force 1355104 is gradually separated from the substrate along the stretching direction, and due to the van der Waals force, the selected plurality of nano-tube segments are respectively associated with other nanocarbons. The segment = is continuously pulled out to form a carbon nanotube film or the raw material cost and preparation method of the ITO wire, because the long carbon nanotube line provided by the technical solution is pulled by the stretching tool Obtained that the method does not require a vacuum environment and a heating process, so the long carbon nanotube tube manufactured by the above method is used as the first wire 112 and the second wire 122,

Therefore, the preparation of the touch screen 100 provided by the technical solution also has the advantages of low cost, environmental protection and energy saving. It can be understood that 'because the carbon nanotubes in the super-sequential carbon nanotube array of the present embodiment are very pure', since the specific surface area of the carbon nanotubes itself is not large, the long carbon nanotubes themselves have strong viscosity. < The carbon tube long line as the first wire 112 and the second wire 122 may be directly adhered to the first surface 142 and the second surface 144 of the second substrate i40, respectively. The tube film or the carbon nanotube long line may be further processed by using the nanocarbon formed in the above step 2, or by applying a solvent to the surface of the substrate or applying a mechanical external force. Specifically, the organic solvent may be dropped into the surface of the nanotube film of the above step 2 or the surface of the long carbon wire of the carbon nanotube by the test tube to infiltrate the entire nanometer stone reverse film or the long line of the carbon nanotube tube. The organic solvent is a volatile organic solvent such as ethanol, decyl alcohol, propylene ketone, diethylene bromide or chloroform, and ethanol is preferably used in this embodiment. After the nanocarbon tube film or the long carbon nanotube tube is infiltrated with an organic solvent, the parallel carbon nanotube segments are partially aggregated into the carbon nanotube bundle under the surface tension of the volatile organic solvent. Therefore, the surface area ratio of the 15 nm carbon nanotubes is small, no (4), and the upper and the 1 can be made in the macroscopic field. The carbon nanotube film or the long carbon wire of the carbon nanotube can be formed by a force: the force is processed to obtain the carbon nanotube length of a stranded structure: carbon: long, yarn axis. Rotate the two by rotating the two to rotate the spinning shaft in a long line of the H-carbon tube. It can be understood that the rotation of the above-mentioned spinning shaft can be reversed or reversed, or the forward and reverse phases can be processed.

At this time, the external circuit 152 is disposed outside the touch screen 100. The first wire 112 is connected to the capacitance sensing element 15G, and the capacitance sensing element 15G continuously senses the capacitance change of all the first wires 112. Since the sweeping speed of the external circuit is very fast, when the capacitances of the plurality of points are simultaneously changed, the capacitance change of the plurality of points can be detected by the capacitive sensing element 150 at almost the same time. The capacitive sensing element 150 includes one or more chips (not shown) that record the position coordinates of the corresponding plurality of first wires 112. The capacitance sensing component 150 measures the capacitance change on the first wire 112, outputs the changed coordinates of the first wire 112, and the coordinates of the corresponding second wire 122 input from the external circuit 152, thereby obtaining the one or more Touch the coordinates of the point. In this embodiment, the capacitive sensing element 15 is integrated with the first end of the first wire 112 on the first surface 132 of the first substrate 130 and electrically connected to the first wire 112. It can be understood that the first wire guide 12 can also be electrically connected to the capacitive sensing element 15 through a wire. At this time, the capacitive sensing element 150 is disposed outside the touch screen. 17 1355104 _ The respective sensing elements 15A and the external circuit 152 can be connected by a wire, and the external circuit 152 scans the second wire 122 while continuously inputting the scanning coordinates to the capacitive sensing element 15〇 . Therefore, the capacitive sensing element 15 is configured to simultaneously obtain the positional coordinates of the second wire 122 where the change point is located while sensing the change in capacitance of the first wire 112. In an improved manner, the touch screen 100 has a different refractive index and transmittance of light in a region where the first wire 112 and the wire 122 are disposed and a region where the first wire 112 and the second wire 122 are not disposed, so that the touch screen 100 is transparent. The visual difference between the optical properties is minimal, and the first conductive layer 110 and the second conductive layer 120 may further include a filling layer 160, respectively. The material of the filling layer 160 formed in the gap between the first wires 112 and the plurality of second wires 122 has the same or close refractive index and material as the first wires 112 and the second wires 122. Transmittance. Progressively, in order to extend the service life of the second conductive layer 12A and limit the capacitance between the contact point and the second conductive layer 12A, a transparent protective layer may be disposed on the layer φ. 17〇, the protective layer 17〇T is formed of materials such as bismuth, telluride, stupid and cyclobutene (BCB), polyester or acrylic resin. The protective layer 170 has a certain hardness and wear resistance to protect the conductive layer. It can be understood that the protective layer 17 can be processed by a special process such as reducing glare, reducing reflection, and the like. In this embodiment, a polyethylene terephthalate (PET) layer is disposed on the second conductive layer 12〇 as a protective layer 17〇, and the hardness of the protective layer 17〇 reaches 7H (H is Luo In the hardness test, after the main test force is removed, the depth of the indentation remains under the initial force of 18 1355104. It will be appreciated that the hardness and thickness of the protective layer 170 can be selected as desired. The protective layer 170 may be directly bonded to the second conductive layer 12 by a deadting agent, or may be press-bonded together with the second substrate 14 formed with the second conductive layer 120 by a hot pressing method. In addition, in order to reduce the electromagnetic interference generated by the display device and to avoid errors in the signal emitted from the touch screen 100, a shielding layer M0 may be disposed on the first surface 134 of the first substrate 130. The shielding layer 18 can be made of an indium tin oxide (ITO) film, a tantalum oxide (AT〇) film, or a thin nickel metal film.

The carbon nanotube film can be an oriented or otherwise structured carbon nanotube film. In this embodiment, the shielding layer is a carbon nanotube thin, and the carbon nanotube film comprises a plurality of carbon nanotubes, and the plurality of nano carbon members are aligned in the carbon nanotube film. The specific structure may be the same as the long line of the above-mentioned Nailai carbon tube. The carbon nanotube film acts as an electrical grounding point and acts as a shield, so that the touch screen can be placed in an interference-free environment. Referring to FIG. 3, and in conjunction with FIG. 2, the embodiment of the present invention provides a display device 200, which includes a touch screen 1 and a display device 210. The display device 21 is facing and close to the touch screen. Further, the display device 21 described above is disposed adjacent to and adjacent to the second surface 134 of the first substrate 130 of the touch screen. The display device 21A and the touch panel 100 described above may be spaced apart by a predetermined distance or integrated. The display device 210 can be a liquid crystal display, a field emission display, an electro-polymer display, an electro-acoustic wire (four), a vacuum fluorescent display (four), and a conventional display device such as a cathode ray tube. In addition, the display device 2 can be 19 1355104. A flexible display such as a flexible liquid crystal display, a flexible electrophoretic display, or a flexible organic electro-optical display. Referring to FIG. 4, further, when the display device 210 is disposed at a distance from the touch screen 100, a passivation layer 220 may be disposed on a surface of the shielding layer 180 of the touch screen 100 away from the substrate 130. The passivation layer 220 may be made of nitrogen. It is formed from materials such as bismuth, antimony telluride, benzocyclobutene (BCB), polyester or acrylic resin. The passivation layer 220 is disposed with a gap 230 between the front side of the display device 210. Specifically, two support bodies 240 are disposed between the passivation layer 220 and the display device 210 described above. The passivation layer 220 is used as a dielectric layer that protects the display device 210 from damage due to excessive external force. When the display device 210 is integrated with the touch screen 100, the touch screen 100 and the display device 210 are in contact with each other. Immediately after the support body 240 is removed, the passivation layer 220 is provided on the front surface of the display device 210 without a gap. In addition, the display device 200 further includes a touch screen controller 250, a display device controller 260, and a central processing unit 270. The touch screen controller 250, the central processing unit 270, and the display device controller 260 are connected to each other through a circuit. The touch screen controller 250 is connected to the capacitive sensing element 150 of the touch screen 100, and the display device controller 260 is connected to the display device 210°. For example, the principle of the touch screen 100 and the display device 200 is as follows: The touch screen 1 can be directly disposed on the display surface of the display device 210 when the application is applied. The capacitive sensing element 150 transmits the capacitance change and coordinate position information of the touch points of the touch object 300 on the touch screen 100 to the touch screen controller 260. The touch screen controller 260 transmits the 20 of the plurality of touch points along with the coordinate position information to the 270 through the display device controller 26 to convert the capacitance change to the digital signal central processor 270. The central processing controls the display device 210 to display. Specifically, in use, the external circuit 152 and the plurality of second wires 122 alternately supply driving voltages. When the second wire 122 is driven, the first wire 112 and the second wire 122 overlap to generate a plurality of sensing capacitors. At the same time, the user is in a position to visually recognize the display of the display device 210 disposed behind the touch screen 1 ” while pressing or approaching the protective layer of the touch screen 10G by a touch object such as a finger or a pen, and when operating, touch (4) The one or more different touch points generated on the touch screen 100 cause the capacitance at the one or more intersections to change. For high-frequency currents, the capacitor is a direct conductor, so at the same time, the finger draws one or more currents from one contact point. The one or more currents respectively flow out from the capacitive sensing element 150 on the touch screen 100, such that the chip in the capacitive sensing element 150 recognizes the coordinate position corresponding to the first conductive line ι2 in which the capacitance change occurs. The capacitance sensing element 15 输出 outputs the change value of the capacitance, the changed coordinates of the first wire 112, and the coordinates of the corresponding second wire 122 input from the external circuit 152 to the touch panel controller 26A. The touch screen controller 260 transmits the capacitance change and position information of the digitized touch point to the central processor 270, and the central processor 27 receives and performs the capacitance change and position information of the touch point described above. Finally, the central processing unit 27 transmits the capacitance change and position information of the touched point to the display controller 26A, thereby displaying the touch information emitted by the contact 3 on the display device 210.
