[0043] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the following will be combined with the accompanying drawings for the embodiments of the present application to make a clear and complete description of the technical solutions of the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. And the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. Based on the described embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort belong to the scope of protection of the present application.

The terms "connect" or "connected" and similar terms are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect.

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

[0046] In the related art, the pattern of the touch electrode is periodically arranged, and the pattern of the pixel is also periodically arranged. The superimposed pattern of the two generates moire. For the cause of the moire, a simple model is introduced as an example, as shown in Figure 1 The period of the periodically arranged first line pattern is Q1, the period of the periodically arranged second line pattern is Q2, the orthographic projection of the two has overlap, and the angle between the second line pattern and the horizontal direction is r. Then the moire spacing generated after the superposition of the two is m is an integer. Thus, the moire of the pattern with orthographic projection overlap is caused by the periodic arrangement of the two patterns.

[0047] The embodiments of the present application provide a display panel, as shown in Figures 2 to 6 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 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 between the sub-pixel opening areas 6; the first direction X and the second direction Y intersect;

[0049] The touch conductive layer 2 comprises: a plurality of touch electrodes 201 arranged along the first direction X and the second direction Y in the display area AA; the touch electrode 201 comprises: a plurality of hollow areas 3 arranged in an array, and a non-hollow area 4 between the hollow areas 3; the hollow area 3 and the non-hollow area 4 are both overlapped with the sub-pixel group 5 in the orthographic projection of the display substrate 1; the hollow area 3 comprises a strip-shaped hollow area 3-1;

[0051] The display panel provided by the embodiments of the present disclosure is characterized in that: the maximum width of the same type of sub-pixel opening area in different sub-pixel groups in the first direction is not completely the same, that is, the pattern of the plurality of sub-pixel opening areas in the plurality of sub-pixel groups is no longer periodically arranged. At least one of the following is not completely the same: the width of the hollow area in the first direction, the width of the non-hollow area between adjacent two hollow areas in the first direction, and the angle between the extension direction of the strip-shaped hollow area and the first direction in the region corresponding to different sub-pixel groups, that is, the pattern of the touch electrode in the region corresponding to different sub-pixel groups is no longer periodically arranged. At least one of the pattern of the plurality of sub-pixel opening areas in the plurality of sub-pixel groups and the pattern of the touch electrode in the region corresponding to different sub-pixel groups is no longer periodically arranged, so that the optical interference caused by the superposition of the two periodically arranged patterns to form moire can be alleviated or even avoided, and the display effect can be improved.

[0052] In specific implementations, the maximum width of the opening areas of the same seed pixel in different sub-pixel groups may not be completely the same in the first direction X. For regions corresponding to different sub-pixel groups, the width of the cutout area in the first direction X may be the same, the width of the non-cutout area between two adjacent cutout areas may be the same, and the angle between the extension direction of the strip-shaped cutout area and the first direction X may be the same. Alternatively, the maximum width of the opening areas of the same seed pixel in different sub-pixel groups may be the same in the first direction X. For regions corresponding to different sub-pixel groups, at least one of the following may not be completely the same: the width of the cutout area in the first direction X, the width of the non-cutout area between two adjacent cutout areas in the first direction X, and the angle between the extension direction of the strip-shaped cutout area and the first direction X. Alternatively, the maximum width of the opening areas of the same seed pixel in different sub-pixel groups may not be completely the same in the first direction X, and for regions corresponding to different sub-pixel groups, at least one of the following may not be completely the same: the width of the cutout area in the first direction X, the width of the non-cutout area between two adjacent cutout areas in the first direction X, and the angle between the extension direction of the strip-shaped cutout area and the first direction X.

[0053] In some embodiments, such as Figure 5 As shown, the hollow area 3 includes: a first strip-shaped hollow area 301 extending along a third direction, and / or a second strip-shaped hollow area 302 extending along a 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 cutout area includes a strip-shaped cutout area, that is, each cutout area is a strip-shaped cutout area.

[0055] Alternatively, in some embodiments, such as Figure 5 As shown, the second strip-shaped cutout area 302 is connected to the first strip-shaped cutout area 301. That is, each cutout area includes two integrated strip-shaped cutout areas 3-1: the first strip-shaped cutout area 301 and the second strip-shaped cutout area 302.

[0056] In some embodiments, the angles between the third direction, the fourth direction, and the first direction Y are the same. That is, the angles between the extension directions of the first strip-shaped cutout area and the extension directions of the second strip-shaped cutout area and the first direction Y are the same.

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

[0058] In the display device provided in this embodiment, the display panel is a liquid crystal display panel, and the side of the touch conductive layer that faces away from the liquid crystal layer is the display side of the display panel. For example...Figure 2 As shown, the facing substrate 102 includes a first substrate 1021, and a black matrix 1022 and a plurality of color resist 1023 on the side of the first substrate 1021 facing the liquid crystal layer 103. The black matrix 1022 includes a plurality of opening regions 10221, and the color resist 1023 is located at least in the opening regions. The opening regions 10221 are the sub-pixel opening regions 6, and the regions of the black matrix 1022 between the opening regions 10221 are the non-opening regions. The touch conductive layer 2 is located on the side of the first substrate 1021 away from the black matrix 1022. Such a display device in which the touch conductive layer 2 is arranged on the side of the first substrate 1021 of the facing substrate 102 away from the liquid crystal layer 103 is called an SLOC display device.

[0059] Of course, in some embodiments, the display panel can also be an organic light-emitting diode (OLED) panel or a micro light emitting diode display (Micro LED) panel.

[0060] In some embodiments, as shown, Figure 2 As shown, the array substrate 101 includes a second substrate 1011, and a plurality of sub-pixel units 1012 on the side of the second substrate 1011 facing the liquid crystal layer 103; the sub-pixel unit 1012 includes a thin film transistor TFT, and a pixel electrode 10121 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. At least one peripheral region of the display region in the second direction X. The array substrate or the facing substrate further includes a common electrode. Figure 2 In some embodiments, the array substrate 101 includes the common electrode 1018. Figure 2 In some embodiments, the common electrode 1018 is located on the side of the pixel electrode 10121 away from the second substrate 1011. Of course, it is also possible that the pixel electrode is located on the side of the common electrode away from the second substrate. The common electrode or the pixel electrode includes a plurality of slits; the extension direction of the slits intersects both the first direction Y and the second direction X.

[0061] In some embodiments, Figure 2The thin-film transistor (TFT) in the array has a top-gate structure, meaning the gate G is located on the side of the active layer 10122 facing away from the second substrate 1011. The array substrate 101 also includes: a buffer layer 1013 located between the active layer 10122 and the second 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. Alternatively, the gate can be located between the active layer and the second substrate, the gate insulating layer can be located between the active layer and the gate, and the source and drain electrodes can be directly connected to the active layer.

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

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

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

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

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

[0067] In some embodiments, such as 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 sequentially along the first direction X.

[0068] In some embodiments, the first sub-pixel opening region, the second sub-pixel opening region, and the third sub-pixel opening region included in the sub-pixel group form a pixel.

[0069] In some embodiments, as Figure 3 shown, any two adjacent sub-pixel opening regions 6 in the second direction Y are of the same type of sub-pixel opening region 6. That is, a column of sub-pixel opening regions 6 are all the first sub-pixel opening region 601, or the second sub-pixel opening region 602, or the third sub-pixel opening region 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 each pixel are the same, and while avoiding the periodic arrangement of sub-pixel groups, the pixel size uniformity is ensured.

[0071] In some embodiments, as Figure 3 shown, in the sub-pixel group 5, the maximum widths of different sub-pixel opening regions 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 region 601 in the first direction X is d1, the maximum width of the second sub-pixel opening region 602 in the first direction X is d2, and the maximum width of the third sub-pixel opening region 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 region 601 is the same, the d2 of each second sub-pixel opening region 602 is the same, and the d3 of each third sub-pixel opening region 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 region in the first direction X is d1i, the maximum width of the second sub-pixel opening region in the first direction X is d2i, and the maximum width of the third sub-pixel opening region 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] wherein k is a positive integer, v is the remainder.

[0080] That is, in the display panel provided by the embodiment of the present application, the pattern of the plurality of sub-pixel opening regions in the plurality of sub-pixel groups is no longer periodically arranged. When i≤d11-k, d1i=d11-(i-1), that is, when i≤d11-k, the maximum width of the first sub-pixel region in a row of sub-pixel rows in the first direction X decreases in turn according to the rule of d11, d11-(i-1), the maximum width of the second sub-pixel region in the first direction X decreases in turn according to the rule of d2i=d1i+k, and the maximum width of the third sub-pixel region in the first direction X decreases in turn according to the rule of d3i=d1i-k, which can ensure the non-periodic arrangement of the plurality of sub-pixel groups while avoiding the display uniformity being affected by the too large size difference of the same sub-pixel region in adjacent sub-pixel groups. When i>d11-k, the maximum width of the first sub-pixel region in a row of sub-pixel rows in the first direction X is arranged according to the rule of d1i=d1v, the maximum width of the second sub-pixel region in the first direction X is arranged according to the rule of d2i=d1i+k, and the maximum width of the third sub-pixel region in the first direction X is arranged according to the rule of d3i=d1i-k, which can ensure the non-periodic arrangement of the plurality of sub-pixel groups while avoiding the display non-uniformity caused by the too large size difference of the same sub-pixel region at different positions.

[0081] In some embodiments, as shown in FIG. 6, the minimum width of the adjacent third sub-pixel opening region 603 and the first sub-pixel opening region 601 in the first direction X is a first width a, the minimum width of the adjacent first sub-pixel opening region 601 and the second sub-pixel opening region 602 in the first direction X is a second width b, and the minimum width of the adjacent second sub-pixel opening region 602 and the third sub-pixel opening region 603 in the first direction X is a third width c. Figure 3 In some embodiments, as shown in FIG. 7, in one sub-pixel group column 9, the a of each sub-pixel group 5 is the same, the b of each sub-pixel group 5 is the same, and the c of each sub-pixel group 5 is the same.

[0082] Figure 3 In some embodiments, as shown in FIG. 8, the first width a, the second width b, and the third width c of different sub-pixel groups 5 are not completely the same. Thus, while the d1i, d2i, and d3i meet the foregoing requirements, the width H of different sub-pixel groups 5 in the first direction X can be ensured to be equal, that is, the a+b+c+d1i+d2i+d3i of different sub-pixel groups 5 corresponds to H, and H is the same.

[0083] In some embodiments, as shown in FIG. 8, the first width a, the second width b, and the third width c of different sub-pixel groups 5 are not completely the same. Thus, while the d1i, d2i, and d3i meet the foregoing requirements, the width H of different sub-pixel groups 5 in the first direction X can be ensured to be equal, that is, the a+b+c+d1i+d2i+d3i of different sub-pixel groups 5 corresponds to H, and H is the same. Figure 3

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

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

[0086] When 1 < i, ai = a1 + λ;

[0087] bi = ai + λ;

[0088] ci = ai - λ;

[0089] Where 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, and the minimum width between adjacent two 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 equal to 16 microns, k, and λ as 2 as an example, the size of the 6 sub-pixel groups is introduced, and d1i, d2i, d3i, ai, bi, and ci are shown in Table 1.

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

[0095] In some embodiments, as shown in ​ The width of the hollow area 3 in the first direction X, the width of the non-hollow area 4 between adjacent two hollow areas 3 in the first direction X, and the angle between the extension direction of the strip-shaped hollow area 3-1 and the first direction X are not all the same.

[0096] In some embodiments, in a column of sub-pixel groups, the width of the hollow area in the first direction X, the width of the non-hollow area between adjacent two hollow areas in the first direction X, and the angle between the extension direction of the strip-shaped hollow area and the first direction X are the same.

[0097] In some embodiments, as shown in ​As shown in FIG. 1, in the region of the touch electrode 201 corresponding to the i-th sub-pixel group (not shown) of a row of sub-pixel rows (not shown), the width of the hollow region 3 in the first direction X is Wi; wherein n is an integer greater than 1, i is an integer greater than 0 and less than or equal to n, and Wi is in units of microns; when 1 < i < n, Wi satisfies:

[0098] Wi = W1 + (i-1) x (-1) i .

[0099] In some embodiments, as shown in FIG. 1, in the region of the touch electrode 201 corresponding to the i-th sub-pixel group (not shown) of a row of sub-pixel rows (not shown), the width of the non-hollow region 4 between two adjacent hollow regions 3 in the first direction X is Pi, and Pi is in units of microns; when 1 < i < n, Pi satisfies: ​ Pi = P1 + a x (-1) n-1 .

[0100]

[0101] Wherein a is a positive integer.

[0102] In some embodiments, as shown in FIG. 1, in the region of the touch electrode 201 corresponding to the i-th sub-pixel group (not shown) of a row of sub-pixel rows (not shown), the angle Ti between the extension direction of the strip-shaped hollow region 3-1 and the first direction X satisfies: ​

[0103] The display panel provided by the embodiments of the present application has a pattern of touch electrodes of different sub-pixel groups in a row of sub-pixel rows, Wi = W1 + (i-1) x (-1) i , Pi = P1 + a x (-1) n-1 ,

[0104] Thus, while the pattern of touch electrodes is arranged non-periodically, the size and pattern of the hollow regions and non-hollow regions of the touch electrodes corresponding to adjacent sub-pixel groups in a row of sub-pixel rows can be prevented from being too different, thereby preventing the difference in transmittance from being too large and affecting display uniformity. In some embodiments, the width of the hollow region in the first direction X is greater than or equal to 10 microns and less than or equal to 45 microns;

[0105] The width of the non-hollow region between two adjacent hollow regions in the first direction X is greater than or equal to 6 microns and less than or equal to 15 microns;

[0106] The angle between the extension direction of the strip-shaped hollow region and the first direction X is greater than or equal to 15° and less than or equal to 40°.

[0107]

[0108] ​​Next, taking W1=30 microns, P1=12 microns, and a=2 as an example, the parameters of the touch electrodes corresponding to the six sub-pixel groups are introduced, as shown in Table 2. Wi, Pi, Ti are shown in Table 2.

[0111] In some embodiments, as shown in FIG. 6, the shape of the sub-pixel opening region 6 is a rectangle; or, as shown in FIG. 7, the shape of the sub-pixel opening region A1 is a non-rectangle. ​ ​

[0112] The display device provided by the embodiments of the present application includes the display panel provided by the embodiments of the present application.

[0114] The display device provided by the embodiments of the present application is any product or component with a display function, such as a mobile phone, a tablet computer, a television, a display, a notebook computer, a digital photo frame, a navigator, etc. Other essential components of the display device should be understood by those skilled in the art, and are not described here in detail, nor should they be regarded as limitations on the present application. The implementation of the display device can refer to the embodiments of the display panel described above, and repeated descriptions are omitted.

[0115] In summary, the display panel and the display device provided by the embodiments of the present application are as follows: the maximum width of the same sub-pixel opening regions located in different sub-pixel groups in the first direction is not exactly the same, i.e., the pattern of the multiple sub-pixel opening regions in the multiple sub-pixel groups is no longer periodically arranged. At least one of the width of the hollow region in the first direction, the width of the non-hollow region between the two adjacent hollow regions in the first direction, and the included angle between the extension direction of the strip-shaped hollow region and the first direction in the region corresponding to the different sub-pixel groups is not exactly the same, i.e., the pattern of the touch electrodes in the region corresponding to the different sub-pixel groups is no longer periodically arranged. At least one of the pattern of the multiple sub-pixel opening regions in the multiple sub-pixel groups and the pattern of the touch electrodes in the region corresponding to the different sub-pixel groups is no longer periodically arranged, so that the moiré caused by the superposition of the two periodically arranged patterns can be alleviated or even avoided, and the display effect can be improved.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications falling within the scope of the present application. ​​
