Along with the continuous improvement of the comprehensive performance of the display panel, the application field of the touch panel is also expanding continuously. The DOT touch technology is one of the touch technologies commonly used in the OLED field at present. In DOT touch technology, a patterned metal grid structure is usually formed on an encapsulation layer of an OLED by direct evaporation, and the metal grid structure can form a touch electrode layer of a display panel, however, the set touch electrode layer is often opaque and can shield light rays of the display panel, so that display effect of the display panel and imaging recognition effect of fingerprints are reduced.
As shown in fig. 1, fig. 1 is a schematic plan view of a touch electrode provided in the prior art. The light-emitting display area of the display panel comprises a plurality of light-emitting pixels, and the plurality of light-emitting pixels are arranged in an array mode and form the light-emitting area of the display panel. In the embodiment of the present application, a pixel unit in a light emitting pixel is described as an example.
The touch panel includes an array substrate and a light emitting device layer 110 disposed on the array substrate. In the embodiment of the present application, since the light emitting device layer 110 is shown in the schematic plan view in fig. 1, the array substrate is not shown, and the array substrate is a thin film transistor array substrate commonly used in the prior art, and when the array substrate is arranged, the arrangement can be performed according to a conventional technology, and detailed descriptions thereof are omitted.
The light emitting device layer 110 includes a plurality of pixel units 10, where the plurality of pixel units 10 are arranged in an array to form the light emitting area of the display panel, and the pixel units 10 include a plurality of light emitting sub-pixels. Specifically, the light emitting sub-pixels may include a green sub-pixel 100, a red sub-pixel 101, and a blue sub-pixel 102.
In order to realize the touch function, a touch electrode, that is, a grid electrode 103 in the embodiment of the present application, is further disposed on the light emitting device layer 110, where the grid electrode 103 is disposed in a non-light emitting region 106 corresponding to the periphery of the light emitting region 104 of each light emitting sub-pixel.
Since the mesh electrode 103 is opaque, when the touch panel realizes touch recognition, light transmittance is easily reduced, and thus recognition effect and display effect of the panel are affected. The embodiment of the application provides a touch panel, which improves the structure of a touch electrode, thereby improving the touch performance and display effect of the touch panel.
Fig. 2 is a schematic plan view of a touch electrode of a touch panel according to an embodiment of the application. The light-emitting device layer of the touch panel comprises a plurality of pixel units arranged in an array, and the pixel units are arranged in an array and form the whole light-emitting area of the touch panel. In the embodiment of the present application, a pixel unit 10 is described as an example. When the pixel units 10 are arranged in the light emitting device layer, they may be arranged along a first direction X and a second direction Y, where the first direction X and the second direction Y form a certain angle with each other. Preferably, the angle between the first direction X and the second direction Y may also be any other value.
In the embodiment of the present application, a plurality of light emitting sub-pixels are respectively disposed in each pixel unit 10, and the light emitting sub-pixels include a plurality of sub-pixels with different colors, such as a first color sub-pixel, a second color sub-pixel, and a third color sub-pixel, and in the embodiment of the present application, the first color sub-pixel is taken as a green sub-pixel 100, the third color sub-pixel is taken as a red sub-pixel 101, and the second color sub-pixel is taken as a blue sub-pixel 102 for illustration. In the light-emitting region 104 in the region formed by each light-emitting subpixel, the region formed between two adjacent subpixels is a non-light-emitting region 106, and the region formed between the green subpixel 100 and the red subpixel 101 is the non-light-emitting region 106.
The grid electrode 103 is aligned with the light emitting sub-pixels, that is, the grid center of the grid electrode 103 is aligned with the light emitting sub-pixels, the grid electrode 103 is disposed in a non-light emitting area 106 formed between each sub-pixel, and after the grid electrode 103 is disposed, a "mouth" sub-grid structure is formed inside the pixel unit 10. As shown in fig. 2.
In order to improve the light transmittance of the touch panel, in the embodiment of the present application, when the grid electrode 103 is disposed, the corresponding electrode in the peripheral area of at least one sub-pixel in the pixel unit 10 is disposed in a discontinuous grid structure. In the embodiment of the application, the discontinuous grid structure is exemplified by a wiring opening structure or a hole digging structure. By forming the openings on the grid electrode 103, when light passes through the grid electrode 103 again, the openings are formed, so that the light can be ensured to be completely transmitted out of the openings, the light transmittance of the touch panel is further effectively ensured, and the comprehensive performance of the touch panel is improved.
Specifically, in the embodiment of the present application, when the discontinuous grid electrode 103 is disposed, the discontinuous grid electrode 103 is disposed in the non-light-emitting region 106 around the blue subpixel 102 in the pixel unit 10. Specifically, the non-light-emitting areas 106 are formed between the periphery of the blue sub-pixel 102 and the sub-pixels of different colors, so the grid electrode 103 in the non-light-emitting area 106 corresponding to each side of the blue sub-pixel 102 is configured as a routing opening 107.
In the embodiment of the present application, when the wiring opening 107 is configured, for the blue sub-pixel 102, the wiring openings 107 may be respectively disposed in the plurality of non-light-emitting areas 106, that is, the wiring openings 107 are respectively disposed in the non-light-emitting areas 106 corresponding to the four sides of the blue sub-pixel 102. Thus, the routing openings 107 are formed with openings around the blue sub-pixels 102, and when light is injected into and out of the bottom or the top of the touch panel, the light directly passes through the opening structure, so that the light transmittance of the touch panel is effectively improved, and the comprehensive performance of the panel is improved.
Further, in the case of disposing the wiring opening 107, in order to ensure the light transmittance, the width between the grid electrodes corresponding to the two sides of the opening of the wiring opening 107 is greater than 5um. Therefore, when the routing openings 107 are disposed in the non-light-emitting areas 106 corresponding to the four sides of the blue subpixel 102, the opening width of each routing opening 107 is the same.
Preferably, for an actual touch product, when the grid electrode 103 is disposed, the routing openings 107 of the grid electrode 103 may also be disposed in the non-light-emitting areas 106 corresponding to at least two sides of the blue sub-pixel 102, and the widths of the routing openings 107 corresponding to one side of each side may be the same or different, but the widths of the routing openings 107 are ensured to be greater than 5um. Thus, when light passes through the grid electrode 103, the light can be completely transmitted through the routing opening 107, so as to ensure the light transmittance of the touch panel.
Fig. 3 is a schematic plan view of another touch electrode according to an embodiment of the application. In the embodiment of the present application, when the grid electrode 103 is disposed, the grid electrode 103 is disposed correspondingly in the non-light-emitting region 106 of each sub-pixel, thereby preventing the grid electrode 103 from affecting the display effect of the display panel. Specifically, when the wiring opening of the mesh electrode 103 is provided, the electrode may be directly hollowed out in the non-light-emitting region 106 corresponding to one side of the blue subpixel 102, and thus the mesh electrode 103 is not provided between the adjacent regions of the blue subpixel 102 and the green subpixel 100. Since the grid electrode 103 is not arranged in the area, more light can pass through the area, thereby effectively improving the performance of the touch panel.
Preferably, when the mesh electrode 103 around the blue subpixel 102 is provided, the routing openings of the mesh electrode 103 around the blue subpixel 102 may be provided as different openings. Specifically, in the embodiment of the present application, the first routing opening 1071 and the second routing opening 1072 are taken as examples for illustration. The opening width of the first wire opening 1071 is larger than the opening width of the second wire opening 1072, and meanwhile, the first wire opening 1071 and the second wire opening 1072 are disposed in the non-light emitting region 106 corresponding to two adjacent sides, in this embodiment, the first wire opening 1071 may completely dig out the electrode in the region, and in the region corresponding to the second wire opening 1072, the width of the second wire opening 1072 is set to be larger than 5um. Meanwhile, the electrodes corresponding to the other areas of the four sides of the blue sub-pixel 102 can be symmetrically arranged with the electrodes on the opposite sides thereof, so that the uniformity of light rays when passing through the touch electrode is ensured, and the touch performance and the light emitting performance of the touch panel are ensured.
Further, when the routing openings of the grid electrode 103 provided in the embodiment of the present application are provided, the routing openings may also be provided in the non-light-emitting area 106 corresponding to the periphery of the red sub-pixel 101 or the green sub-pixel 100, and the structure forming the routing openings is removed or prepared by the grid electrode 103 around the sub-pixel, so that the transmittance of light in the area is effectively improved, and the touch recognition performance and the comprehensive performance of the touch panel are improved.
Fig. 4 is a schematic structural diagram of another grid electrode according to an embodiment of the present application, as shown in fig. 4. The light-emitting region of the touch panel is formed of a plurality of light-emitting units. Wherein the light emitting unit corresponds to the pixel unit. As shown in fig. 4, an array grid cell of 3*3 is exemplified. The light emitting region is formed by arranging a plurality of pixel units 10 in an array, and the pixel units 10 are the pixel units described above in the embodiment of the present application. Wherein, in the pixel unit, a discontinuous grid electrode is arranged in the periphery of at least one sub-pixel.
Specifically, the grid electrode 103 in the light emitting area is correspondingly disposed in the peripheral position of each light emitting sub-pixel, and finally forms a complete touch electrode. In the embodiment of the present application, since each pixel unit 10 is provided with the discontinuous grid electrode 15, the discontinuous grid electrodes 15 in a part of the area of the formed light emitting array 3*3 are also distributed periodically and regularly.
Referring to fig. 4 in detail, since the discontinuous grid electrodes 15 are arranged periodically, the discontinuous grid electrodes 15 can be arranged at intervals of the same number of light emitting sub-pixels. In the array of 3*3, the discontinuous grid electrodes 15 are arranged at two intervals, when the distance between one side of each sub-pixel and the grid electrode 103 corresponding to the side is a, and when the first discontinuous grid electrode 15 is arranged at the position corresponding to the ith light-emitting sub-pixel, the next adjacent discontinuous grid electrode 15 is arranged at the position corresponding to the (i+2) th light-emitting sub-pixel, and the distance between the non-light-emitting areas of the two adjacent discontinuous grid electrodes 15 is 6a, so that the ith light-emitting sub-pixel is taken as a target position, and the distances between the non-light-emitting areas of the two adjacent discontinuous grid electrodes 15 and the ith light-emitting sub-pixel are all 6a, 12a and 24a … ….
Further, as shown in fig. 5, fig. 5 is a schematic diagram of an arrangement structure of another touch electrode according to an embodiment of the present application. In connection with the schematic layout in fig. 3. At this time, the light emitting area in fig. 5 is an array of 5*5, and the discontinuous grid electrodes 15 in the embodiment of the present application are also periodically arranged in the entire light emitting area. Specifically, when the structure of the discontinuous mesh electrode 15 is provided in the peripheral non-light-emitting region of the i-th light-emitting subpixel, the structure of the discontinuous mesh electrode 15 is also provided in the non-light-emitting region corresponding to the periphery of the i+4-th light-emitting subpixel. In this way, a plurality of discontinuous grid electrodes 15 are provided in the non-light emitting region of the entire touch panel. When light passes through the area corresponding to the discontinuous grid electrode 15, the shielding of the grid electrode 103 is not generated, or only part of the grid electrode 103 is shielded, so that more light can pass through the grid electrode 103, and the comprehensive performance of the touch panel is effectively improved.
Therefore, for the n×n light emitting unit array, when the discontinuous grid electrode 15 is disposed, n-1 light emitting sub-pixels are spaced between two adjacent discontinuous grid electrodes 15, that is, when the discontinuous grid electrode 15 is disposed in the region corresponding to the ith light emitting sub-pixel, the discontinuous grid electrode 15 structure is also disposed in the region corresponding to the ith+nth light emitting sub-pixel. Thereby ensuring that the arranged discontinuous grid electrodes 15 can be arranged in the light-emitting area in an array manner, effectively ensuring the stability of light and improving the comprehensive performance of the touch panel.
Furthermore, the grid electrode 103 in the embodiment of the present application may be further configured as a diamond grid cell or an arc grid cell structure, and meanwhile, the discontinuous grid electrode may also be disposed in an area corresponding to sub-pixels of the same color or different colors, and the specific shape and structure of the grid cell may be further configured according to the type and use of the actual product, so as to ensure improvement and enhancement of the overall performance of the product.
