Recently, an electrophoretic display device (EPD : ELECTROPHORETIC DISPLAY).

In recent years, along with the research and development of the technical aspects of display devices, the necessity of research and development has been particularly emphasized in terms of product design that can appeal to consumers. Accordingly, there is an increasing demand for a design in which a thickness of a display device is minimized and an aesthetic sense that can appeal to a user's aesthetic sense and stimulate purchase is promoted.

In the case of a liquid crystal display device, conventionally, a lower case and an upper case are used to accommodate a liquid crystal display panel and a backlight unit. In addition, a separate front set A cover and rear set cover were additionally used. As described above, the use of the lower case and the upper case, as well as the front and rear set covers of the product, have limitations in reducing the thickness of the liquid crystal display or changing the design. In particular, since the upper case and the front set cover cover the upper edge of the liquid crystal display panel, the thickness of the liquid crystal display device can not be increased. In addition, the edge width of the liquid crystal display device is increased, It is an obstacle to devising innovative designs.

In addition, the liquid crystal display panel is configured such that the upper color filter substrate and the lower array substrate are bonded together, and one side of the array substrate is formed to protrude from the color filter substrate. This is because the pad area is formed on one side of the array substrate which is not overlapped with the color filter substrate. Since the pad area remains as an empty space when the liquid crystal display panel is coupled with the cover glass of the touch panel, when the impact is applied, the impact is concentrated on the empty space, thereby damaging the product or damaging the pad part. Is required.

The adhesive resin may be applied to the first portion with a thickness greater than the distance between the array substrate and the cover glass.

The adhesive resin may be applied to the first portion and the second portion through the same process.

The adhesive resin may be applied through a mask having an opening corresponding to the shape of the first portion.

The filling region may be a portion that is relatively weak compared to the other region due to external impact. At this time, the filling region may be a notch portion around both corner portions on one side of the structure and a position where the user button is mounted.

The structure may further include a color filter substrate disposed between the array substrate and the cover glass.

According to another embodiment of the present disclosure, a method of manufacturing a display device is provided. The method comprises: Fabricating a display panel by facing the array substrate and the color filter substrate; A first portion corresponding to a filling region to which an adhesive resin is further applied for reinforcement of rigidity in one surface of a cover glass and a second portion corresponding to a second portion of the cover glass excluding the first portion on one surface of the cover glass ; And adhering the cover glass and the display panel to each other with the adhesive resin interposed therebetween.

The step of applying the adhesive resin may be a step of applying an adhesive resin to the first portion to be thicker than the second portion.

The step of applying the adhesive resin may be a step of applying the adhesive resin to the first portion and the second portion by the same process through a mask having an opening corresponding to the shape of the first portion.

Various embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

1 is an exploded perspective view schematically showing a structure of a liquid crystal display device.

The liquid crystal display device includes a display panel 110 in which pixels are arranged in a matrix form to display an image, drivers 115 and 116 for driving the pixels, A backlight unit for emitting light toward the display panel 110, and a panel guide 145 for receiving and fixing the display panel 110 and the backlight unit.

The display panel 110 includes an array substrate, a color filter substrate, and a liquid crystal layer interposed between the color filter substrate and the array substrate.

On the array substrate, elements for controlling and driving pixels are disposed. The array substrate is provided with a plurality of gate lines spaced apart from each other by a predetermined distance and arranged in one direction, a plurality of data lines spaced apart at a predetermined interval in a direction perpendicular to the gate lines, A plurality of pixel electrodes formed in a matrix form in each pixel region, and a thin film transistor (TFT) for controlling a voltage of a data signal applied to the pixel electrode on a pixel-by-pixel basis. In the case of an in-plane switching (IPS) liquid crystal display device, a common electrode is located on an array substrate having the pixel electrode.

A color set of red light, green light or blue is arranged on the color filter substrate. Each color set of the color filter substrate filters the white light so that red light, green light or blue light is emitted at the corresponding pixel. The common electrode may be located on the color filter substrate.

When an electric field is applied to the liquid crystal layer through the common electrode and the pixel electrode and the voltage of the data signal applied to the pixel electrode is controlled in a state in which the voltage is applied to the common electrode, And the image is displayed by transmitting or blocking light for each pixel by rotating by dielectric anisotropy according to the electric field between the electrodes.

Upper and lower polarizers are attached to the outside of the display panel 110. The lower polarizer polarizes the light passing through the backlight unit and the upper polarizer polarizes the light passing through the display panel 110. [

The backlight unit includes a light emitting diode (LED) assembly 130 for generating light on one side of a light guide plate 142 and a reflection plate 141 on the back side of the light guide plate 142 do. The LED assembly 130 includes an LED array 131 and a LED housing 132 to which an LED printed circuit board (PCB) for driving the LED array 131 is attached.

Light emitted from the LED array 131 is incident on a side surface of the light guide plate 142. The reflective plate 141 disposed on the back surface of the light guide plate 142 reflects light transmitted through the back surface of the light guide plate 142 toward the optical sheet 143 on the upper surface of the light guide plate 142 to reduce light loss and improve uniformity .

On the top of the backlight unit, a display panel 110 including the color filter substrate and the array substrate is seated through a panel guide 145. The display panel 110, the panel guide 145, and the backlight unit are coupled to each other by the lower case 180 and the upper case 190 to constitute a liquid crystal display device.

The display device may further include a cover glass coupled with the display panel 110. Since the user must view the visual information implemented by the display panel 110 through the cover glass, the cover glass is made of glass or plastic having high transparency. Further, it is preferable that the cover glass is made of tempered glass or a reinforced plastic material so that it can withstand the everyday external impacts. The cover glass is a rectangular transparent substrate having a certain thickness and can be attached to the upper portion of the upper polarizer plate through an adhesive film. The cover glass corresponds to both the display area AA and the non-display area NA of the display panel and may extend further to the outside of the non-display area NA.

The touch sensor can be located inside or outside the display panel. The touch sensor can be coupled with the display panel in the form of a touch screen panel having a separate substrate. Alternatively, the touch sensor can be combined with the display panel in the form of a film. Alternatively, the touch sensor may be on the color filter substrate and / or the array substrate in the form of a touch electrode. When a touch screen panel is added to the display device, the cover glass may be located above the touch panel.

2A and 2B are plan views schematically showing the structure of a display device according to an embodiment of the present invention. FIG. 2B shows a structure in which the cover glass 111 is coupled to the display panel shown in FIG. 2A.

The display device includes a display panel 110 in which pixels are arranged in a matrix form to output an image, a backlight unit (not shown) installed on the rear surface of the display panel 110 and emitting light over the entire surface of the display panel 110, And a case component (not shown) for receiving and fixing the display panel 110 and the backlight unit. Hereinafter, for convenience of explanation, a mold having the display panel 110 and the cover glass 111 coupled thereto is referred to as a panel structure.

The display panel 110 of FIG. 2A includes a color filter substrate 101, an array substrate 102, and a liquid crystal layer between the color filter substrate 101 and the array substrate 102 facing each other.

The color filter substrate 101 separates a color filter composed of a plurality of sub-color filters implementing the colors of red, green, and blue and the sub-color filter, A black matrix for blocking light transmitted therethrough, and a transparent common electrode for applying a voltage to the liquid crystal layer.

The array substrate 102 includes a gate line and a data line arranged vertically and horizontally, a thin film transistor located at an intersection of the gate line and the data line, and a pixel electrode located in the pixel region. In this case, in the case of an in-plane switching (IPS) liquid crystal display device, a common electrode is located on the array substrate 102 instead of the color filter substrate 101.

A display panel 110 including the color filter substrate 101 and the array substrate 102 is mounted on the upper part of the backlight unit through a panel guide. The display panel 110, the panel guide, and the backlight unit are screw- The liquid crystal display device is connected to the lower case and the upper case through a plurality of fastening means.

At this time, on the display panel 110, a touch panel (not shown) for inputting letters or pictures more easily and precisely is attached. At this time, a cover glass 111 of the touch panel is adhered And is attached to the edge of the display panel 110 through the layer 118.

As described above, the display panel 110 includes a color filter substrate 101 and an array substrate 102 disposed therebelow. The array substrate 102 has a color filter substrate 101 ). This is because the pad region 102a having the pad portion 115 is located on one side of the array substrate 102 which is not overlapped with the color filter substrate 101. [

An integrated circuit chip may be mounted on the pad region 102a by a chip on glass method. A protection layer covers the pad electrodes to protect the integrated circuit chip. Electronic components for processing driving signals may be mounted on a flexible printed circuit board (FPCB) 117 connected to the pad unit 115 by a chip on film method, A connector for transmitting an external signal to the flexible circuit board 117 may be provided. The flexible circuit board 117 may be folded back to the rear of the display panel 110 and attached to the rear surface of the display panel 110.

An anisotropic conductive film (ACF) may be used to electrically connect the connection portions of the pad portion 115 and the flexible circuit board 117 with each other.

At this time, the adhesive layer 118 made of a resin having elasticity and adhesive force is filled in the empty space between the specific portion of the pad region 102a and the cover glass 111, The pad portion 115 can be prevented from being damaged. That is, in order to reinforce the rigidity of the panel structure, the adhesive resin (resin) is injected into the specific application region through the injector.

A resin having an elastic force and an adhesive force is filled in a void space between a part of the pad region 102a and the cover glass 111 during a direct bonding process of the cover glass 111, Thereby forming a predetermined adhesive layer 118. [ The process of forming the adhesive layer 118 may be referred to as gap filling in order to fill an empty space.

Particularly, in the case of a mobile product such as a smart phone, a predetermined adhesive layer 118 is provided at the edge of the pad region 102a of the array substrate 102 to absorb an external shock even when an impact is applied due to dropping or the like, The portion 115 is prevented from being damaged. On the other hand, the adhesive layer 118 may be formed through a curing process after resin application.

3A is a flowchart showing a method of manufacturing a liquid crystal display device according to an embodiment of the present invention, and FIG. 3B is a flowchart specifically showing a module process among the manufacturing methods shown in FIG. 3A.

At this time, FIG. 3A shows an example of forming a liquid crystal layer by a liquid dropping method, but the present invention is also applicable to a method of manufacturing a liquid crystal display device when a liquid crystal layer is formed by a liquid crystal injection method.

The manufacturing process of the liquid crystal display device can be largely divided into a driving element array process for forming driving elements on the lower substrate, a color filter process for forming a color filter on the upper substrate, a cell process and a module process.

The cell process is a process of injecting and attaching liquid crystals using a completed array substrate and a color filter substrate, and aligning the array substrate, the color filter substrate and the array substrate by aligning the alignment film, the liquid crystal, the sealant and the spacer. The module process is a process of manufacturing a circuit for signal processing, connecting a display panel and a signal processing circuit portion, and attaching an instrument to manufacture a module.

First, a plurality of gate lines and data lines are arranged in an array process, and thin film transistors to be connected to the gate lines and the data lines are formed in pixel regions, respectively (S101). In addition, in the array process, a pixel electrode for driving the liquid crystal layer is formed as a signal is applied through the thin film transistor.

On the other hand, in the color filter process, a color filter layer composed of red, green, and blue sub-color filters and a common electrode are formed on the color filter substrate (S102). In the case of the liquid crystal display device of the transverse electric field type (IPS), the common electrode is formed on the array substrate through the array process (S101).

Next, in the cell process, the orientation film is printed on the color filter substrate and the array substrate, respectively, and then the alignment regulating force or the surface fixing force (that is, pretilt angle) is applied to the liquid crystal molecules of the liquid crystal layer formed between the color filter substrate and the array substrate ) And the alignment direction), the alignment film is rubbed (S103, S104).

A sealing material is applied to the rubbed color filter substrate to form a predetermined seal pattern, and a liquid crystal layer is formed by dropping liquid crystal on the array substrate (S105, S106).

At this time, a plurality of the color filter substrate and the array substrate are divided into a large-sized mother substrate. In other words, a plurality of panel regions are defined in a large-sized mother substrate, and thin film transistors and color filters, which are driving elements, are formed in each of the panel regions.

At this time, the dropping system dispenses liquid crystal to an image display area of a large-area first mother substrate on which a plurality of array substrates are arranged or a second mother substrate on which a plurality of color filter substrates are arranged using a dispenser, And the liquid crystal is uniformly distributed over the entire image display area by the pressure for attaching the first and second mother substrates to each other, thereby forming a liquid crystal layer.

Therefore, when the liquid crystal layer is formed on the second mother substrate through the dropping method, the seal pattern must be formed in a closed pattern surrounding the periphery of the pixel region so as to prevent the liquid crystal from leaking out of the image display region.

The dropping method can drop the liquid crystal in a shorter time than the vacuum injection method, and even when the display panel is enlarged, the liquid crystal layer can be formed very quickly. In addition, since only a necessary amount of liquid crystal is dropped onto the substrate, the cost of the display panel can be prevented from rising due to disposal of expensive liquid crystal such as a vacuum injection method, thereby enhancing the price competitiveness of the product.

Thereafter, the first mother substrate and the second mother substrate are bonded together by applying a pressure in a state in which the first mother substrate and the second mother substrate, to which the liquid crystal is dropped and the sealing material is coated, are aligned, The liquid crystal dropped by the application of the pressure is uniformly spread over the display panel (S107).

By this process, a large number of unit display panels having liquid crystal layers are formed on the first and second large-sized mother substrates, and the first and second mother substrates are processed and cut into a plurality of unit display panels (S108).

Then, in the module process, the unit display panel and the signal processing circuit are connected by a mounting technique, and then a module is attached by attaching an apparatus (S109).

That is, in order to accomplish this, a cleaning process is performed to remove foreign matter existing on the surface of the display panel before the polarizer is attached to the upper and lower surfaces of the display panel (S109-1). After the cleaned display panel is aligned, the release film of the polarizing plate is peeled off, and a polarizing plate is attached to the upper and lower surfaces of the display panel (S109-2). A TAB (Tape Automatic Bonding) is attached to the pad portion of the display panel. The TAB has a driving integrated circuit (IC) in itself, (S109-3). The process of punching in the TCP (Tape Carrier Package) state to make it attachable to the display panel and attaching it to the pad portion of the display panel using the anisotropic conductive film is referred to as a TAB attaching process. Then, after a predetermined defoamation is performed, a signal input from the outside is divided into a control signal and a data signal and is sent to the TCP. In order to supply a voltage for driving the display panel, (S109-4, S109-5). Then, the cover glass of the touch panel is attached to the display panel (S109-6). Then, the panel guide, the lower case, and the upper case are assembled to protect the product from changes in the external environment such as mechanical compression such as shock or vibration and high temperature, low temperature and high humidity from the outside by assembling the backlight assembly at the lower part of the display panel. (S109-7). After completing the remaining module processes, the respective display panels are inspected to manufacture a liquid crystal display device (S109-8, S110). At this time, in order to prevent breakage of the product or damage of the pad portion due to an external impact before the cover glass is attached, a process of applying a resin having an elastic force and an adhesive force (gap filling) to a part of the pad region of the display panel (S109-6).

FIG. 4A is a schematic view of a gap filling method according to an embodiment of the present invention, and FIG. 4B is a sectional view of a gap-filled panel structure.

The display panel 110 is loaded on the table 210 for the gap filling process. At this time, a dispenser 220 for applying a resin 229 to a predetermined region of the display panel 110 is disposed on the table 210.

When the display panel 110 is loaded on the table 210, the dispenser 220 moves to the application position and applies the resin 229 through the nozzle 221. At this time, the resin 229 is applied to a defined region (for example, both end portions of the pad region), and the resin 229 thus coated is cured to form an adhesive layer 118.

After the resin 229 is applied, the display panel 110 is unloaded, and the dispenser 220 is moved to the cleaner. When the cleaner is installed in the table 210, the dispenser 220 moves to the cleaner in the table 210.

The cover glass 111 is placed on the upper part of the display panel 110 to which the adhesive resin 229 is applied and then the resin is cured to complete the panel structure including the gap fill 118. The filling region into which the adhesive resin is injected for rigid reinforcement can be defined between the array substrate of the panel structure and the cover glass.

Although the gap filling process of the above process is advantageous in that the rigidity of the panel structure is enhanced, there is a disadvantage that the production cost is increased due to the separate process for gap filling. Thus, the following suggests a simpler method of gap filling.

5A to 5E are views for explaining a gap filling method according to another embodiment of the present invention.

The above method is a method of applying an adhesive resin 175 on both sides of the cover glass 170 for both adhesion with the display panel and gap filling. 5A, a cover glass 170 is placed on a table 210, a plate dispenser 220 is coated with resin (resin) for adhesion to a display panel on one side of a cover glass 170, do. At this time, a predetermined portion on the side of the cover glass corresponds to a gap fill region. The filling region is a region in which at least a portion of the side surface portion of the panel structure is filled with resin for buffer light. The filling region can be defined as a portion requiring rigidity reinforcement in the panel structure. Alternatively, it may be defined as a portion that is vulnerable to structural impact, for example, a portion adjacent to a portion where the adjustment button for the user is placed. Thus, the filling region may be defined as (1) both corner portions on one side of the panel structure, and (2) the both corner portions and the notch portion on the center, as in 118 of FIG. The fill region is located at least on one side of the panel structure when viewed in plan and is located between the array substrate and the cover glass when viewed in cross section.

The fill region may be located at the edge (or along the edge) of the panel structure. For example, the fill region may be located at the first side edge E1 of the panel structure and / or at the second side edge E2 adjacent to the first side edge. The length of the first side edge E1 and the length of the second side edge E2 may be equal to or different from each other depending on the shape of the panel structure. The first side edge E1 and the second side edge E2 may be edges corresponding to the display area, but the first side edge and the second side edge may extend to extend to the edge of the outermost portion. have. One filling region may be located only on one side edge or continuously on two side edges. The filling region may be located at each corner of the panel structure.

A patterning mask 230 is used to apply to the cover glass 170 up to the resin to be filled in the filling region. The mask 230 is used in a process of applying an adhesive resin (resin) to one side of the cover glass 170. As shown in FIG. 5B, the mask 230 is shaped such that adhesive resin is deposited on a portion (first portion) corresponding to the resin filling region of the cover glass 170. That is, the mask 230 has an opening corresponding to the shape of the first portion. Thus, adhesive resin is not applied to the portion of the cover glass 170 that does not correspond to the filling region on one side (left side in FIG. 5B).

The adhesive resin 175 is coated on one surface of the cover glass as a mask. Figure 5c shows some exemplary forms in which the adhesive resin 175 is applied. When the mask has a shape as shown in Fig. 5B, the applied adhesive resin 175 also follows its shape. In Fig. 5C, (1) is an adhesive resin applied through the mask shown in (1) of Fig. 5B, and the resin to be filled in the filling region is located at both left corner and square at the center. In Fig. 5C, (2) is an adhesive resin applied through the mask shown in (2) of Fig. 5B, and both left corners have a resin to be filled in a filling region, and both portions are connected in arc form. In addition, the application form may be varied, and the application area of the adhesive resin can be easily changed by making the mask into a desired shape according to the number / arrangement of the filling areas.

At this time, a portion (first portion, 175-2) corresponding to the filling region is stacked thicker than a portion (second portion, 175-1) of the adhesive resin in contact with the display panel. This is to fill the filling region sufficiently, so that the adhesive resin can be applied to the portion 175-2 corresponding to the filling region at a height equal to or greater than the distance between the cover glass and the lower array substrate. In the portion 175-2 corresponding to the filling region, when the dispenser of the adhesive resin moves at a slower speed, the adhesive resin can be accumulated thicker than the other portion 175-1. Therefore, in the portion 175-2 corresponding to the filling region, the dispenser of the adhesive resin moves at a speed corresponding to the determined stacking height. 5D is a side view of the cover glass 170 and the adhesive resin 175 applied thereon. The thicker portion of the adhesive resin indicates the resin applied to the portion 175-2 corresponding to the filling region. The adhesive resin 175 is applied to the first portion and the second portion through the same process.

As shown in FIG. 5D, the cover glass 170 coated with the adhesive resin 175 on one side is bonded to the display panel 110. 5E, when the cover glass 170 and the display panel 110 are bonded together, the adhesive resin 175 adheres the cover glass 170 and the color filter substrate 101, and further fills the filling area And serves to adhere the cover glass 170 and the array substrate 102 to each other.

6 is a flowchart illustrating a method of manufacturing a display device according to another embodiment of the present invention.

The above-described manufacturing method is similar to a typical liquid crystal display device manufacturing method, but includes the following characteristic steps. First, the array substrate and the color filter substrate are adhered to each other to form a display panel (S610). For a detailed description thereof, reference is made to the description of Figs. 3A to 3B.

On the other hand, an adhesive resin is applied to one surface of the cover glass. At this time, an adhesive resin is applied to a first portion corresponding to a filling region where an adhesive resin is additionally applied for reinforcement of rigidity in one surface of the cover glass, and to a second portion of the cover glass which is in contact with the display panel ). And the adhesive resin is applied to the first portion to be thicker than the second portion. The step S620 may be a step of applying the adhesive resin to the first portion and the second portion by the same process through a mask having an opening corresponding to the shape of the first portion, 5a to 5d.

Next, the cover glass and the display panel are bonded together with the adhesive resin interposed therebetween (S630). The panel structure manufactured through this process can perform the gap filling for improving the rigidity with a simple procedure at a low cost. Accordingly, the above-described manufacturing method can greatly contribute to reduction of manufacturing cost and quality of a display device.
