Description

Technical Field

[0001] This invention relates to the field of display technology, and in particular to an electrode structure, a touch substrate, an array substrate, and a display device. Background Technology

[0002] With the rapid development of display technology, touch display panels have been widely accepted and used, such as in smartphones and tablets. Touch display panels utilize embedded touch technology to combine the touch panel and display panel into one unit, embedding the touch panel functionality within the display panel, thus enabling the display panel to simultaneously display and sense touch input.

[0003] Depending on how the touch sensing layer is positioned within the display panel, touch display panels are categorized into add-on, in-cell, and on-cell structures. In-cell touchscreens integrate touch functionality into the display, effectively reducing the overall thickness of the display and simplifying manufacturing processes, resulting in thinner, lighter products with lower production costs, making them widely popular. For add-on and on-cell touchscreens, to prevent the touch electrodes from affecting light transmittance, the touch electrodes are typically designed with a grid-like structure. The metal grid often uses highly periodic patterns such as rhombuses, rectangles, and regular hexagons.

[0004] In addition, the display panel contains a thin film transistor array substrate (TFT array substrate), and the multiple scan lines and multiple data lines on the thin film transistor array substrate will intersect to form a grid structure. The grid structure is usually a highly periodic pattern such as a rhombus or rectangle.

[0005] Because the display panel contains a metal mesh with a highly periodic pattern, it easily interferes with the highly periodic RGB pixels, forming moiré patterns. This reduces the display quality and affects the user's visual experience. Current technology can only reduce moiré patterns by extending the repetition period of the metal mesh; however, it cannot completely eliminate them. Summary of the Invention

[0006] In order to overcome the shortcomings and deficiencies of the prior art, the present invention aims to provide an electrode structure, a touch substrate, an array substrate, and a display device to solve the problem of moiré patterns caused by metal meshes with highly periodic patterns on the touch substrate and / or array substrate in the prior art.

[0007] The objective of this invention is achieved through the following technical solution:

[0008] The present invention provides an electrode structure, including a metal mesh, wherein the metal mesh is formed by non-periodicly tiling multiple first patterned grids, multiple second patterned grids, multiple rotationally symmetric patterned grids of the first patterned grids, and multiple rotationally symmetric patterned grids of the second patterned grids, wherein the first patterned grids and the second patterned grids are axisymmetric structures.

[0009] The first graphic grid is a thirteen-sided polygon, and the interior angles of the thirteen-sided polygon, from the first vertex to the thirteenth vertex in a clockwise direction, are 90°, 240°, 90°, 240°, 90°, 120°, 120°, 270°, 120°, 90°, 120°, 270°, and 120°.

[0010] Furthermore, the side lengths of the thirteen-sided polygon, in a clockwise direction, are as follows: , , , , , , , , , , , , , where a>0.

[0011] This application also provides a touch substrate, wherein the touch substrate is provided with touch electrodes, and the touch electrodes adopt the electrode structure described above.

[0012] Furthermore, the touch electrode includes a first touch electrode layer and a second touch electrode layer. The first touch electrode layer includes multiple mutually insulated touch driving electrode strips, and the first touch electrode layer is disconnected between two adjacent touch driving electrode strips. The second touch electrode layer includes multiple mutually insulated touch sensing electrode strips, and the second touch electrode layer is disconnected between two adjacent touch sensing electrode strips. The extending direction of the touch driving electrode strips is perpendicular to the extending direction of the touch sensing electrode strips.

[0013] Furthermore, the touch electrode includes a plurality of touch areas arranged in an array, and the touch electrode is disconnected between two adjacent touch areas.

[0014] This application provides an array substrate, on which a first metal electrode layer and a second metal electrode layer are provided. Both the first metal electrode layer and the second metal electrode layer adopt the electrode structure described above. The first metal electrode layer includes multiple scan lines and is interrupted between two adjacent scan lines. The second metal electrode layer includes multiple data lines and is interrupted between two adjacent data lines. The extension direction of the scan lines is perpendicular to the extension direction of the data lines.

[0015] Furthermore, the opening regions of the metal mesh in the first metal electrode layer and the opening regions of the metal mesh in the second metal electrode layer are projected onto the array substrate.

[0016] Furthermore, the first metal electrode layer also includes a gate electrically connected to the scan line, and each of the first pattern grids, each of the second pattern grids, each rotationally symmetric pattern grid of the first pattern grids, and each rotationally symmetric pattern grid of the second pattern grids in the first metal electrode layer is provided with a gate.

[0017] The second metal electrode layer further includes a source and a drain. The source is electrically connected to the data line, and the drain is disconnected from the source at the active layer. The source and the drain are provided in each of the first pattern grids, each of the second pattern grids, each rotationally symmetric pattern grid of the first pattern grid, and each rotationally symmetric pattern grid of the second pattern grid in the second metal electrode layer.

[0018] Furthermore, the array substrate is provided with pixel electrodes electrically connected to the drain electrode, and the shape of the pixel electrodes corresponds to the opening area of ​​the metal mesh.

[0019] This application also provides a display device, including the touch substrate as described above and / or the array substrate as described above.

[0020] The beneficial effects of this invention are as follows: by using a special-shaped mesh structure to non-periodicly lay the metal mesh of the electrode structure, the mesh arrangement of the metal mesh is not periodic at all, completely avoiding periodic overlapping patterns, fundamentally improving the moiré pattern of the display device and enhancing the display quality of the display device; moreover, all the mesh patterns of the metal mesh are obtained from a single pattern through rotational symmetry and axial symmetry, reducing the design difficulty of the metal mesh and lowering the design cost.

Figure 2 This is a schematic diagram of the structure of the first graphic grid in this invention. Figure 3 This is a schematic diagram of the structure of the second graphic grid in this invention. Figure 4 This is a schematic diagram of the electrode structure in this invention.

[0039] like Figures 1 to 4 As shown, the present invention provides an electrode structure including a metal mesh 100. The metal mesh 100 is formed by non-periodicly tiling multiple first patterned grids 110, multiple second patterned grids 120, multiple rotationally symmetric patterned grids of the first patterned grids 110, and multiple rotationally symmetric patterned grids of the second patterned grids 120. The first patterned grids 110 and 120 are axially symmetric structures. The rotationally symmetric patterned grids of the first patterned grids 110 are obtained by rotating the first patterned grids 110, and the rotationally symmetric patterned grids of the second patterned grids 120 are obtained by rotating the second patterned grids 120. The rotation angle can be set according to the tiling arrangement. The metal mesh 100 can be made of metals such as copper (Cu), silver (Ag), chromium (Cr), molybdenum (Mo), aluminum (Al), titanium (Ti), manganese (Mn), nickel (Ni), etc., or combinations of the above metals such as Al / Mo, Cu / Mo, etc.

[0040] like Figure 1 As shown, the first graphic grid 110 is a thirteen-sided polygon with 13 vertices. The 13 vertices, arranged clockwise, are: first vertex D1, second vertex D2, third vertex D3, fourth vertex D4, fifth vertex D5, sixth vertex D6, seventh vertex D7, eighth vertex D8, ninth vertex D9, tenth vertex D10, eleventh vertex D11, twelfth vertex D12, and thirteenth vertex D13. The interior angles corresponding to the first vertex D1 to the thirteenth vertex D13 are θ1, θ2, θ3, θ4, θ5, θ6, θ6, θ8, θ9, θ10, θ11, θ12, and θ13, respectively. The interior angles of the thirteen-sided polygon, in a clockwise direction from the first vertex D1 to the thirteenth vertex D13, are θ1=90°, θ2=240°, θ3=90°, θ4=240°, θ5=90°, θ6=120°, θ7=120°, θ8=270°, θ9=120°, θ10=90°, θ11=120°, θ12=270°, and θ13=120°.

[0041] In this embodiment, the side lengths of the thirteen-sided polygon are as follows in a clockwise direction: , , , , , , , , , , , , , where a>0, a can be set according to the size of the first graphic grid 110, and the unit of a can also be selected according to actual needs, such as micrometer, nanometer and angstrom.

[0042] like Figure 1 As shown, the first graphic grid 110 is located within three adjacent regular hexagons, each with a side length of 'a'. The three adjacent regular hexagons are designated as regular hexagon 1, regular hexagon 2, and regular hexagon 3, arranged in a triangular pattern. One vertex of each of the three regular hexagons coincides with the others, and one side of any two adjacent regular hexagons also coincides with each other. Among them, the first vertex D1, the second vertex D2, the third vertex D3, the fourth vertex D4, the fifth vertex D5, the sixth vertex D6, the seventh vertex D7, the eighth vertex D8, the ninth vertex D9, the tenth vertex D10, the eleventh vertex D11, the twelfth vertex D12, and the thirteenth vertex D13 are located in a clockwise direction at the midpoint of the side length of the first regular hexagon 1, the inflection point of the side length where the first regular hexagon 1 and the second regular hexagon 2 coincide, the midpoint of the side length of the second regular hexagon 2, and the second regular hexagon 3. The center point of hexagon 2, the midpoint of the side length of the second regular hexagon 2, the inflection point of the side length of the second regular hexagon 2, the inflection point of the side length of the second regular hexagon 2 and the third regular hexagon 3 that coincide, the midpoint of the side length of the second regular hexagon 2 and the third regular hexagon 3 that coincide, the center point of the third regular hexagon 3, the midpoint of the side length of the third regular hexagon 3, the inflection point of the side length of the first regular hexagon 1 and the third regular hexagon 3 that coincide, the midpoint of the side length of the first regular hexagon 1 and the third regular hexagon 3 that coincide, and the center point of the first regular hexagon 1.

[0043] This application achieves non-periodic tiling of the metal mesh 100 of the electrode structure using a special-shaped mesh structure, thereby making the mesh arrangement of the metal mesh 100 non-periodic and completely avoiding periodic overlapping patterns, fundamentally improving the moiré pattern of the display device and enhancing the display quality of the display device; moreover, all the mesh patterns of the metal mesh 100 are obtained from a single pattern through rotational symmetry and axial symmetry, reducing the design difficulty of the metal mesh 100 and lowering the design cost.

[0044] Figure 5 This is a schematic diagram of the structure of the touch substrate in this invention. Figure 6 This is a schematic diagram of the structure of the first touch electrode layer in this invention. Figure 7 This is a schematic diagram of the structure of the second touch electrode layer in this invention. Figures 5 to 7As shown, this application also provides a touch substrate 200, on which touch electrodes are provided, and the touch electrodes adopt the electrode structure described above.

[0045] In this embodiment, the touch substrate 200 is a mutual capacitance touch system. The touch electrodes include a first touch electrode layer and a second touch electrode layer, which are located on different layers and are insulated from each other. The first touch electrode layer includes multiple insulated touch driving electrode strips 210, and the first touch electrode layer is disconnected between adjacent touch driving electrode strips 210. The second touch electrode layer includes multiple insulated touch sensing electrode strips 220, and the second touch electrode layer is disconnected between adjacent touch sensing electrode strips 220. The extension direction of the touch driving electrode strips 210 is perpendicular to the extension direction of the touch sensing electrode strips 220. Each touch driving electrode strip 210 and each touch sensing electrode strip 220 are formed by non-periodicly tiling multiple first graphic grids 110, multiple second graphic grids 120, multiple rotationally symmetrical graphic grids of the first graphic grids 110, and multiple rotationally symmetrical graphic grids of the second graphic grids 120. In practice, since the grid lines of the metal mesh 10 have a certain width, it is only necessary to set slots on the grid lines between two adjacent touch driving electrode strips 210 and between two adjacent touch sensing electrode strips 220 to disconnect the two adjacent touch driving electrode strips 210 and between two adjacent touch sensing electrode strips 220.

[0046] Furthermore, a touch chip 230 is provided on the touch substrate 200, and multiple touch driving electrode strips 210 and multiple touch sensing electrode strips 220 are electrically connected to the touch chip 230 at the edge of the touch substrate 200 through signal lines, so that the touch chip 230 can apply touch signals to the multiple touch driving electrode strips 210 and multiple touch sensing electrode strips 220.

[0047] In other embodiments, the touch substrate 200 may also be a self-capacitive touch system, with the touch electrodes comprising a plurality of touch areas arranged in an array, the touch electrodes being disconnected between adjacent touch areas. In practice, since the grid lines of the metal mesh 10 have a certain width, it is only necessary to set slots on the grid lines between adjacent touch areas to disconnect the touch electrodes between adjacent touch areas.

Figure 10 This is a schematic diagram of the structure of a pixel in this invention. Figure 11 This is a schematic diagram of the structure of a grid on the first metal electrode layer in this invention. Figure 12 This is a schematic diagram of the structure of the first metal electrode layer in this invention. Figure 13This is a schematic diagram of a grid structure on the second metal electrode layer in this invention. Figure 14 This is a schematic diagram of the structure of the second metal electrode layer in this invention. (See diagram below.) Figures 8 to 14 As shown, this application also provides an array substrate. The array substrate 20 has a first metal electrode layer and a second metal electrode layer. The first and second metal electrode layers are located on different layers and are insulated from each other. Both the first and second metal electrode layers employ the electrode structure described above. The first metal electrode layer includes multiple scan lines 211, and the first metal electrode layer is interrupted between adjacent scan lines 211. The second metal electrode layer includes multiple data lines 231, and the second metal electrode layer is interrupted between adjacent data lines 231. The extending directions of the scan lines 211 and the extending directions of the data lines 231 are perpendicular to each other.

[0049] like Figure 12 As shown, each scan line 211 is formed by non-periodic tiling of a row of graphic grids (first graphic grid 110, second graphic grid 120, rotationally symmetric graphic grid of first graphic grid 110, and rotationally symmetric graphic grid of second graphic grid 120). Figure 14 As shown, each data line 231 is formed by a non-periodic tiling of a column of graphic grids (first graphic grid 110, second graphic grid 120, rotationally symmetric graphic grids of first graphic grid 110, and rotationally symmetric graphic grids of second graphic grid 120). In practice, since the grid lines of the metal mesh 10 have a certain width, it is only necessary to set slots on the grid lines between adjacent scan lines 211 and adjacent data lines 231 to disconnect the adjacent scan lines 211 and adjacent data lines 231.

[0050] In this embodiment, the projections of the opening areas of the metal mesh 100 of the first metal electrode layer and the opening areas of the metal mesh 100 of the second metal electrode layer onto the array substrate 20 coincide, with each pattern grid area corresponding to one pixel. It is understood that only the projections of the opening areas of the metal mesh 100 of the first and second metal electrode layers onto the array substrate 20 coincide, not the projections of the entire metal mesh 100 of the first and second metal electrode layers onto the array substrate 20. The main reason is that the extension directions of the scan lines 211 and the data lines 231 are different. Therefore, the grid lines of the metal mesh 100 of the first and second metal electrode layers have a certain difference, specifically in the different extension directions of the slots on the grid lines.

[0051] Furthermore, such as Figure 11As shown, the first metal electrode layer also includes a gate 212 electrically connected to the scan line 211. Each first pattern grid 110, each second pattern grid 120, each rotationally symmetrical pattern grid of the first pattern grid 110 and each rotationally symmetrical pattern grid of the second pattern grid 120 are provided with a gate 212. The gate 212 can be connected to any side of the pattern grid.

[0052] like Figure 13 As shown, the second metal electrode layer also includes a source 232 and a drain 233. The source 232 is electrically connected to the data line 231, and the drain 233 is disconnected from the source 232 at the active layer 22. Each first pattern grid 110, each second pattern grid 120, each rotationally symmetric pattern grid of the first pattern grid 110, and each rotationally symmetric pattern grid of the second pattern grid 120 are provided with a source 232 and a drain 233. The gate 212 can be connected to any side of the pattern grid.

[0053] Furthermore, such as Figure 9 As shown, an active layer 22 is provided on the array substrate 20. The active layer 22 is located between the first metal electrode layer and the second metal electrode layer. The active layer 22 corresponds to the gate 212. The source 232 and the drain 233 are electrically connected to the active layer 22 and form a channel at the active layer 22. The gate 212, the active layer 22, the source 232, and the drain 233 together constitute a thin-film transistor.

[0054] Furthermore, such as Figure 9 and Figure 10 As shown, the array substrate 20 is provided with pixel electrodes 24 electrically connected to the drain 233. The shape of the pixel electrodes 24 corresponds to the opening area of ​​the metal grid 100, that is, each pattern grid is provided with a pixel electrode 24.

[0055] Furthermore, a first insulating layer 201 is provided between the first metal electrode layer and the second metal electrode layer, and the two layers are insulated from each other by the first insulating layer 201. A second insulating layer 202 is provided between the second metal electrode layer and the pixel electrode 24, and the two layers are insulated from each other by the second insulating layer 202. The second insulating layer 202 has a contact hole corresponding to the drain electrode 233, and the pixel electrode 24 is electrically connected to the drain electrode 233 through the contact hole.

[0056] Figure 15 This is a schematic diagram of the display device in the dark state in this invention. Figure 16 This is a schematic diagram of the display device in the present invention in the illuminated state. (See attached diagram.) Figure 15 and Figure 16 As shown, this application also provides a display device, including the touch substrate 200 as described above and / or the array substrate 20 as described above.

[0057] In this application, the display device includes a touch substrate 200 as described above and an array substrate 20 as described above. The touch substrate 200 has touch electrodes with the electrode structure described above. The array substrate 20 has a first metal electrode layer and a second metal electrode layer, both with the electrode structure described above. The first metal electrode layer includes multiple scan lines 211, and the second metal electrode layer includes multiple data lines 231.

[0058] In this embodiment, the display device is a liquid crystal display device. The liquid crystal display device includes an array substrate 20, a color filter substrate 10 disposed opposite to the array substrate 20, and a liquid crystal layer 30 located between the array substrate 20 and the color filter substrate 10. The liquid crystal molecules in the liquid crystal layer 30 are positive liquid crystal molecules (liquid crystal molecules with positive dielectric anisotropy). In the initial state, the positive liquid crystal molecules are arranged in a flat position, and the alignment direction of the positive liquid crystal molecules near the color filter substrate 10 is parallel to the alignment direction of the positive liquid crystal molecules near the array substrate 20. It can be understood that the array substrate 20 and the color filter substrate 10 also have an alignment layer facing the liquid crystal layer 30, thereby aligning the positive liquid crystal molecules in the liquid crystal layer 30.

[0059] In this embodiment, the touch substrate 200 is attached to the side of the color filter substrate 10 away from the liquid crystal layer 30. Of course, in other embodiments, the touch substrate 200 can also be integrated with the color filter substrate 10 into a single substrate, that is, the touch electrodes are directly disposed on the color filter substrate 10.

[0060] The color filter substrate 10 has a black matrix 11 and a color resist layer 12. The black matrix 11 corresponds to the scan line 211, data line 231, thin film transistor, and the peripheral non-display area. The color resist layer 12 corresponds to the opening area of ​​the metal mesh 100. The black matrix 11 separates multiple color resist layers 12. The color resist layer 12 includes red (R), green (G), and blue (B) color resist materials, and correspondingly forms red (R), green (G), and blue (B) sub-pixels.

[0061] In this embodiment, a common electrode 25 is further provided on the side of the array substrate 20 facing the liquid crystal layer 30. The common electrode 25 and the pixel electrode 24 are located on different layers and are insulated from each other by an insulating layer. The common electrode 25 may be located above or below the pixel electrode 24. Figure 15 and Figure 16The diagram shows the common electrode 25 located above the pixel electrode 24. Preferably, the common electrode 25 is a planar electrode with its entire surface disposed, and the common electrode 25 has multiple slits in each corresponding pixel unit. The pixel electrode 24 is a block electrode disposed in each pixel unit to form a fringe field switching (FFS) mode. Of course, in other embodiments, the pixel electrode 24 and the common electrode 25 may be located on the same layer, but they are insulated from each other. Both the pixel electrode 24 and the common electrode 25 may include multiple electrode strips, and the electrode strips of the pixel electrode 24 and the common electrode 25 are arranged alternately to form an in-plane switching (IPS) mode. Alternatively, in other embodiments, the array substrate 20 has the pixel electrode 24 on the side facing the liquid crystal layer 30, and the color filter substrate has the common electrode 25 on the side facing the liquid crystal layer 30 to form a TN mode or a VA mode.

[0062] The color filter substrate 10 is provided with an upper polarizer, and the array substrate 20 is provided with a lower polarizer. The transmission axis of the upper polarizer and the transmission axis of the lower polarizer are perpendicular to each other.

[0063] The liquid crystal display device also includes a backlight module 40. The backlight module 40 can be an edge-lit backlight module or a direct-lit backlight module. Preferably, the backlight module 40 adopts a collimated backlight (CBL) mode, which can collect light and ensure display effect.

[0064] like Figure 16 As shown, during the display interruption, the liquid crystal display device applies a common voltage to the common electrode 25 and a corresponding grayscale voltage to the pixel electrode 24 through the data line 231, creating a voltage difference and generating a horizontal electric field between the pixel electrode 24 and the common electrode 25. Figure 16 In the E1 step, the positive liquid crystal molecules in the liquid crystal layer 30 are deflected in the horizontal direction, thereby controlling the intensity of light passing through the liquid crystal layer 30 and achieving grayscale display. The grayscale voltage includes 0 to 255 grayscale voltage levels. When different grayscale voltages are applied to the pixel electrode 24, the pixel unit presents different brightness, thereby enabling the liquid crystal display device to display different images.

[0065] Of course, in other embodiments, the display device may also be a self-emissive display device. As for the specific structure of the self-emissive display device, please refer to the prior art, which will not be described in detail here.
