Technical Field

[0002] The moiré phenomenon is based on the shading effect and the perception characteristics of the human eye. It is a visual phenomenon that occurs when two repetitive structure images (such as grids, gratings, etc.) with similar periodicity overlap. The overlapping image contains a new, clearly visible alternating pattern of light and dark that has never existed in any of the original repetitive structure images.

[0043] To make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme of the embodiments of the present application will be clearly and completely described below in conjunction with the drawings of the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. And in the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. Based on the described embodiments of the present application, all other embodiments obtained by ordinary technicians in the field without creative work belong to the scope of protection of this application.

[0045] It should be noted that the sizes and shapes of the figures in the accompanying drawings do not reflect the actual proportions, but are only intended to illustrate the content of the present application. The same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions.

[0046] In the related art, the pattern of the touch electrodes is arranged periodically, and the pattern of the pixels is also arranged periodically. The interference of the two superimposed patterns produces moiré. The cause of moiré is introduced by taking a simple model as an example. Figure 1 As shown, the period of the first line pattern arranged periodically is Q1, the period of the second line pattern arranged periodically is Q2, the orthographic projections of the two overlap, and the angle between the second line pattern and the horizontal direction is r, then the moiré spacing generated by the superposition of the two is m is an integer. It can be seen that the moiré pattern with overlapping patterns in the orthographic projection is caused by the periodic arrangement of the two patterns.

[0047] The present application embodiment provides a display panel, such as Figure 2 to Figure 6 As shown, the display panel is divided into a display area AA and a peripheral area NA surrounding the display area AA; the display panel comprises: a display substrate 1, and a touch conductive layer 2 located on one side of the display substrate 1;

[0048] The display substrate 1 comprises: a plurality of sub-pixel groups 5 arranged in an array along a first direction X and a second direction Y in a display area AA; the sub-pixel group 5 comprises: a plurality of sub-pixel opening areas 6 arranged along the first direction X, and a non-opening area 7 located between the sub-pixel opening areas 6; the first direction X intersects the second direction Y;

[0051] In the display panel provided by the embodiment of the present disclosure, the maximum widths of the same sub-pixel opening areas in different sub-pixel groups in the first direction are not completely the same, that is, the patterns of the multiple sub-pixel opening areas in the multiple sub-pixel groups are no longer periodically arranged. In the areas corresponding to different sub-pixel groups, at least one of the width of the hollow area in the first direction, the width of the non-hollow area between two adjacent hollow areas in the first direction, and the angle between the extension direction of the strip hollow area and the first direction is not completely the same, that is, the patterns of the regional touch electrodes corresponding to different sub-pixel groups are no longer periodically arranged. At least one of the patterns of the multiple sub-pixel opening areas in the multiple sub-pixel groups and the patterns of the regional touch electrodes corresponding to the different sub-pixel groups are no longer periodically arranged, thereby alleviating or even avoiding the optical interference caused by the superposition of the two periodically arranged patterns to form moiré patterns, and improving the display effect.

[0053] In some embodiments, Figure 5 As shown, the hollow area 3 includes: a first strip-shaped hollow area 301 extending along the third direction, and / or a second strip-shaped hollow area 302 extending along the fourth direction; the third direction intersects with the fourth direction, and the third direction and the fourth direction intersect with the first direction X and the second direction Y.

[0054] In some embodiments, each hollow area includes a strip-shaped hollow area, that is, each hollow area is a strip-shaped hollow area.

[0055] Or, in some embodiments, Figure 5 As shown, the second strip hollow area 302 is connected to the first strip hollow area 301. That is, each hollow area includes two strip hollow areas 3-1, namely, the first strip hollow area 301 and the second strip hollow area 302, which are connected as one.

[0056] In some embodiments, the third direction, the fourth direction and the first direction Y have the same included angle, that is, the extending direction of the first strip-shaped hollow area, the extending direction of the second strip-shaped hollow area and the first direction Y have the same included angle.

[0057] In some embodiments, Figure 4 As shown, the display substrate 1 includes: an array substrate 101 and an opposite substrate 102 arranged opposite to each other, and a liquid crystal layer 103 located between the array substrate 101 and the opposite substrate 102; the touch conductive layer 2 is located on a side of the opposite substrate 102 away from the liquid crystal layer 103.

[0058] That is, in the display device provided by the embodiment of the present disclosure, the display panel is a liquid crystal display panel, and the side of the touch conductive layer away from the liquid crystal layer is the display side of the display panel.

The touch conductive layer 2 is located on the side of the first base substrate 1021 away from the black matrix 1022. This display device in which the touch conductive layer 2 is arranged on the side of the first base substrate 1021 of the counter substrate 102 away from the liquid crystal layer 103 is called a SLOC display device.

[0059] Of course, in some embodiments, the display panel may also be an organic light-emitting diode (OLED) panel or a micro-sized inorganic light-emitting diode (Micro Light Emitting Diode Display, Micro LED) panel.

[0060] In some embodiments, Figure 2 As shown, the array substrate 101 includes: a second base substrate 1011, and a plurality of sub-pixel units 1012 located on the side of the second base substrate 1011 facing the liquid crystal layer 103; the sub-pixel unit 1012 includes: a thin film transistor TFT, and a pixel electrode 10121 located on the side of the thin film transistor TFT facing the liquid crystal layer 103; wherein the thin film transistor TFT includes: an active layer 10122, a gate G, a source S and a drain D, and the pixel electrode 10121 is electrically connected to the drain D of the thin film transistor TFT. In the second direction X, the array substrate or the opposite substrate also includes a common electrode. Figure 2 In the description, the array substrate 101 including the common electrode 1018 is taken as an example. Figure 2 The common electrode 1018 is located on the side of the pixel electrode 10121 away from the second base substrate 1011. Of course, the pixel electrode can also be located on the side of the common electrode away from the second base substrate. The common electrode or the pixel electrode includes a plurality of slits; the extension direction of the slits intersects the first direction Y and the second direction X.

[0061] In some embodiments, Figure 2The thin film transistor TFT in the array is a top gate structure, that is, the gate G is located on the side of the active layer 10122 away from the second base substrate 1011, and the array substrate 101 further includes: a buffer layer 1013 located between the active layer 10122 and the second base substrate 1011, a gate insulating layer 1014 located between the active layer 10122 and the gate G, an interlayer insulating layer 1015 located between the gate G and the source S, a passivation layer 1016 located between the source S and the pixel electrode 10121, and a planarization layer 1017 located between the pixel electrode 10121 and the common electrode 1018. Of course, the gate may be located between the active layer and the second base substrate, the gate insulating layer may be located between the active layer and the gate, and the source and drain may be directly overlapped with the active layer.

[0062] In some embodiments, the touch conductive layer includes a transparent conductive material, such as indium tin oxide (ITO) or indium zinc oxide (IZO).

[0063] In some embodiments, Figure 4 As shown, the touch conductive layer 2 also includes: multiple touch lines 202 and multiple binding pins 203; the touch lines 202 are electrically connected to the touch electrodes 201 and the binding pins 203; the binding pins 203 are located in the peripheral area NA on one side of the display area AA in the second direction Y; the touch lines 202 extend from the display area AA to the peripheral area NA and are electrically connected to the binding pins 203.

[0064] In some embodiments, Figure 3 As shown, n sub-pixel groups 5 arranged along the first direction X form a sub-pixel row 8; in a sub-pixel row 8 in the figure, the first sub-pixel group 5 is recorded as 5-1, the nth sub-pixel group 5 is recorded as 5-n, and when i is greater than 1, the first sub-pixel group 5 is recorded as 5-i;

[0065] The plurality of sub-pixel groups 5 arranged along the second direction Y form a sub-pixel group column 9 .

[0066] In some embodiments, Figure 3 As shown, the sub-pixel group 5 includes: a first sub-pixel opening area 601 , a second sub-pixel opening area 602 and a third sub-pixel opening area 603 .

[0067] In some embodiments, Figure 3 As shown, the first sub-pixel opening area 601 is a red sub-pixel area R, the second sub-pixel opening area 602 is a green sub-pixel area G, and the third sub-pixel opening area 603 is a blue sub-pixel area B. The first sub-pixel opening area 601, the second sub-pixel opening area 602 and the third sub-pixel opening area 603 are arranged in sequence along the first direction X.

[0068] In some embodiments, a pixel is composed of a first sub-pixel opening area, a second sub-pixel opening area, and a third sub-pixel opening area included in a sub-pixel group.

[0069] In some embodiments, as Figure 3 shown, any two adjacent sub-pixel opening areas 6 in the second direction Y are of the same type of sub-pixel opening area 6. That is, a column of sub-pixel opening areas 6 are all the first sub-pixel opening area 601 or the second sub-pixel opening area 602 or the third sub-pixel opening area 603.

[0070] In some embodiments, as Figure 3 shown, the widths H of different sub-pixel groups 5 in the first direction X are all equal. Thereby, it can be ensured that the sizes of all pixels are the same, and the pixel size uniformity is ensured while avoiding the periodic arrangement of sub-pixel groups.

[0071] In some embodiments, as Figure 3 shown, in the sub-pixel group 5, the maximum widths of different sub-pixel opening areas 6 in the first direction X are different.

[0072] In some embodiments, as Figure 3 shown, the maximum width of the first sub-pixel opening area 601 in the first direction X is d1, the maximum width of the second sub-pixel opening area 602 in the first direction X is d2, and the maximum width of the third sub-pixel opening area 603 in the first direction X is d3.

[0073] In some embodiments, as Figure 3 shown, in a column of sub-pixel groups 9, the d1 of each first sub-pixel opening area 601 is the same, the d2 of each second sub-pixel opening area 602 is the same, and the d3 of each third sub-pixel opening area 603 is the same.

[0074] For the sake of easy distinction, in a row of sub-pixel rows, in the i-th sub-pixel group, the maximum width of the first sub-pixel opening area in the first direction X is d1i, the maximum width of the second sub-pixel opening area in the first direction X is d2i, and the maximum width of the third sub-pixel opening area in the first direction X is d3i; n is an integer greater than 1, i is an integer greater than 0 and less than or equal to n, and the units of d1i, d2i, and d3i are micrometers.

[0075] In some embodiments, d1i, d2i, and d3i satisfy:

[0076] When 1 < i ≤ d11 - k, d1i = d11 - (i - 1); when i > d11 - k, d1i = d1v;

[0077] d2i = d1i + k;

[0078] d3i = d1i - k;

[0079] Where k is a positive integer and v is The remainder of .

[0080] That is, in the display panel provided by the embodiment of the present application, the pattern of the multiple sub-pixel opening areas in the multiple sub-pixel groups is no longer arranged periodically. Moreover, when i≤d11-k, d1i=d11-(i-1), that is, when i≤d11-k, the maximum width of the first sub-pixel area in a row of sub-pixels in the first direction X decreases in accordance with the rules of d11 and d11-(i-1), the maximum width of the second sub-pixel area in the first direction X decreases in accordance with the rule of d2i=d1i+k, and the maximum width of the third sub-pixel area in the first direction X decreases in accordance with the rule of d3i=d1i-k, which can ensure that the multiple sub-pixel groups are arranged non-periodically while avoiding the large size difference of the same sub-pixel areas in adjacent sub-pixel groups affecting the display uniformity. When i>d11-k, the maximum width of the first sub-pixel area in a row of sub-pixels in the first direction X is arranged according to the rule of d1i=d1v, the maximum width of the second sub-pixel area in the first direction X is arranged according to the rule of d2i=d1i+k, and the maximum width of the third sub-pixel area in the first direction X is arranged according to the rule of d3i=d1i-k. While ensuring the non-periodic arrangement of multiple sub-pixel groups, it avoids uneven display caused by too large a size difference between the same sub-pixel areas at different positions.

[0081] In some embodiments, Figure 3 As shown, the minimum width of the adjacent third sub-pixel opening area 603 and the first sub-pixel opening area 601 in the first direction X is the first width a, the minimum width of the adjacent first sub-pixel opening area 601 and the second sub-pixel opening area 602 in the first direction X is the second width b, and the minimum width of the adjacent second sub-pixel opening area 602 and the third sub-pixel opening area 603 in the first direction X is the third width c.

[0082] In some embodiments, Figure 3 As shown, in one sub-pixel group column 9, a, b and c of each sub-pixel group 5 are all the same.

[0083] In some embodiments, Figure 3 As shown, the first width a, the second width b, and the third width c in different sub-pixel groups 5 are not completely the same. Therefore, while d1i, d2i, and d3i meet the aforementioned requirements, it is possible to ensure that the widths H of different sub-pixel groups 5 in the first direction X are all equal, that is, a+b+c+d1i+d2i+d3i=H corresponding to different sub-pixel groups 5, and H are all the same.

[0084] For easy distinction, in a row of sub-pixels, in the i-th sub-pixel group, in a row of sub-pixels, the first width in the i-th sub-pixel group 5 is ai, the second width is bi, and the third width is ci, and the units of ai, bi, and ci are micrometers.

[0085] In some embodiments, ai, bi, ci satisfy:

[0086] When 1 <i,ai=a1+λ;

[0087] bi=ai+λ;

[0088] ci=ai-λ;

[0089] Wherein, λ is a positive integer.

[0090] In some embodiments, the maximum width of the sub-pixel opening area in the first direction X is greater than or equal to 20 microns and less than or equal to 70 microns; the minimum width between two adjacent sub-pixel opening areas in the first direction X is greater than or equal to 4 microns and less than or equal to 30 microns.

[0091] Next, taking H=210 microns, d11=54 microns, a1=16 microns, k and λ=2 as an example, the sizes of the 6 sub-pixel groups are introduced, and d1i, d2i, d3i, ai, bi, and ci are shown in Table 1.

[0094] In a specific implementation, n, H, d11, a1, k, and λ may be set according to the required size and resolution of the display panel.

In the areas corresponding to different sub-pixel groups, at least one of the width of the hollow area in the first direction, the width of the non-hollow area between two adjacent hollow areas in the first direction, and the angle between the extension direction of the strip hollow area and the first direction is not completely the same, that is, the pattern of the regional touch electrodes corresponding to different sub-pixel groups is no longer periodically arranged. At least one of the patterns of the multiple sub-pixel opening areas in the multiple sub-pixel groups and the patterns of the regional touch electrodes corresponding to the different sub-pixel groups is no longer periodically arranged, thereby alleviating or even avoiding the optical interference caused by the superposition of the two periodically arranged patterns to form moiré patterns, and improving the display effect.
