[0032] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments of the present application. Based on the embodiments in the present application, any other embodiments obtained by a person of ordinary skill in the art without creative work fall within the scope of protection of the present application. In addition, it should be understood that the specific implementation manners described herein are only used to illustrate and explain the present application, and are not used to limit the present application. In the present application, the embodiments can be combined with each other but are not described one by one, and the positional words such as "upper" and "lower" are generally used to refer to the upper and lower in the actual use or working state of the device, and the specific is the direction of the drawing surface in the drawings; and "inner" and "outer" are used in relation to the outline of the device; the words "first", "second", "third" and the like are only used as labels, and do not impose a numerical requirement or establish an order.

[0033] It needs to be understood that, in the related technology of a touch-embedded liquid crystal display panel, a touch via is generally arranged in the region of a blue sub-pixel. In order to consider the uniformity of light emission, the aperture ratio of the blue sub-pixel in the display area is generally designed to be consistent. At this time, due to the fact that the touch via occupies a certain light shielding area and the requirement of consistent aperture ratio, the aperture ratio of the blue sub-pixel without the touch via is reduced, thereby causing the overall light transmittance of the display area to decrease.

[0034] The display panel and the display device of the embodiments of the present application keep the aperture ratio of the pixel area without the via group by reducing the area of the first electrode adjacent to the via group (equivalent to the touch via) and keeping the area of the second electrode unchanged, thereby improving the light transmittance.

[0035] Embodiments of the present application provide a display panel and a display device, which are described in detail below. It should be noted that the sequence of the following embodiments is not intended to limit the preferred sequence of the embodiments.

[0036] Please refer to Figure 1 and Figure 2 , Figure 1 A top view schematic diagram of a display panel 100 according to an embodiment of the present application is shown. Figure 2 A cross-sectional structure schematic diagram of the display panel 100 according to an embodiment of the present application is shown.

[0037] It should be noted that the display panel 100 is a liquid crystal display panel. The display panel 100 includes an array substrate 10, a counter substrate 20, and liquid crystal disposed between the array substrate 10 and the counter substrate 20.

[0038] Optionally, the array substrate 10 can have a color filter layer or can not have a color filter layer.

[0039] The array substrate 10 includes a plurality of scan lines 11, a plurality of data lines 12, a plurality of pixel electrodes 13, a common electrode 14, a touch trace 15, and a thin film transistor 16.

[0040] The plurality of scan lines 11 and the plurality of data lines 12 are arranged in a cross manner to form a plurality of pixel regions 10a. The pixel electrode 13 is connected to the thin film transistor 16. One pixel electrode 13 is arranged in one pixel region 10a. The common electrode 14 is arranged in a layer different from the pixel electrode 13, and the common electrode 14 is multiplexed as a touch electrode. The touch trace 15 is arranged in a layer different from the common electrode 14, and one touch trace 15 is connected to one common electrode 14 through at least one via group 15a.

[0041] The plurality of pixel electrodes 13 includes a first pixel electrode 131 configured to correspond to a first color sub-pixel. The plurality of first pixel electrodes 131 includes a first electrode 13a and a second electrode 13b, one first electrode 13a and one via group 15a are arranged in one pixel region 10a, and one second electrode 13b is arranged in one pixel region 10a. In the display panel 100 under a top view perspective, the area of the first electrode 13a is smaller than the area of the second electrode 13b.

[0042] Compared with the prior art, the display panel 100 according to the embodiments of the present application reduces the area of the first electrode 13a adjacent to the via group 15a, maintains the area of the second electrode 13b unchanged, so that the aperture ratio of the pixel region 10a without the via group 15a is not lost, thereby improving the light transmittance.

[0043] It should be noted that the common electrode 14 and the pixel electrode 13 are connected to different voltages respectively, and an electric field is generated to drive the liquid crystal to deflect. The thin film transistor 16 can be any type of transistor, which is not limited here.

[0044] The pixel electrode 13 further includes a second pixel electrode 132 and a third pixel electrode 133. The second pixel electrode 132 is configured to correspond to a second color sub-pixel, and the third pixel electrode 133 is configured to correspond to a third color sub-pixel. The first color sub-pixel, the second color sub-pixel and the third color sub-pixel are different in color.

[0045] The first color sub-pixel is one of a red sub-pixel, a green sub-pixel and a blue sub-pixel, the second color sub-pixel is another of the red sub-pixel, the green sub-pixel and the blue sub-pixel, and the third color sub-pixel is the last of the red sub-pixel, the green sub-pixel and the blue sub-pixel.

[0046] For example, the first color sub-pixel is a blue sub-pixel, the second color sub-pixel is a green sub-pixel, and the third color sub-pixel is a red sub-pixel. That is, the first electrode 13a and the second electrode 13b both correspond to the blue sub-pixel.

[0047] It can be understood that, compared with green, the human eye is less sensitive to blue, so the opening group and the blue sub-pixel are arranged in the same pixel area 10a, which has less effect on the display effect.

[0048] In some embodiments of the present application, the pixel electrode 13 is a single-domain pixel electrode, and the extension direction of the slits 1xf of the pixel electrodes 13 in the odd rows is different from the extension direction of the slits 1xf of the pixel electrodes 13 in the even rows.

[0049] In some embodiments of the present application, referring to Figure 2 The via group 15a includes a first via 1a, a second via 2a and a third via 3a. The array substrate 10 further includes a first transfer line 121 arranged above the touch control trace 15 and a second transfer line 135 arranged above the common electrode 14. The first transfer line 121 is arranged in the same layer as the data line 12, and the second transfer line 135 is arranged in the same layer as the pixel electrode 13. The first transfer line 121 is connected to the touch control trace 15 through the first via 1a, one end of the second transfer line 135 is connected to the common electrode 14 through the second via 2a, and the other end of the second transfer line 135 is connected to the first transfer line 121 through the third via 3a.

[0050] In some embodiments, the via group 15a can also have only one via, that is, the touch control trace 15 is connected to the common electrode 14 through one via; or the via group 15a includes two vias, that is, the first transfer line 121 is saved, and the second transfer line 135 is used to connect the touch control trace 15 and the common electrode 14.

[0051] It can be understood that, please combine Figure 3 , Figure 3 The light transmission effect diagram of the single-domain pixel electrode 13 and the dual-domain pixel electrode is shown. According to Figure 3 It can be understood that, please combine The light transmission effect diagram of the single-domain pixel electrode 13 and the dual-domain pixel electrode is shown. According to

[0052] The extension direction of the slit 1xf of the pixel electrode 13 in the odd row is different from the extension direction of the slit 1xf of the pixel electrode 13 in the even row, so as to form an effect similar to the dual-domain pixel to expand the visual viewing angle.

[0053] Optionally, the via group 15a and the first electrode 13a in the first pixel electrode 13 in the odd row are jointly arranged in a pixel area 10a, as Figure 1 Optionally, the via group 15a and the first electrode 13a in the first pixel electrode 13 in the odd row are jointly arranged in a pixel area 10a, as Figure 4 Optionally, the via group 15a and the first electrode 13a in the first pixel electrode 13 in the odd row are jointly arranged in a pixel area 10a, as

[0054] Optionally, in some embodiments, the pixel electrode 13 can also be a dual-domain pixel electrode.

[0055] Optionally, the materials of the pixel electrode 13 and the common electrode 14 can each be indium tin oxide, indium zinc oxide, or other oxides.

[0056] Optionally, in some embodiments of the present application, in the display panel 100 under the top view angle, the touch control trace 15 is located on one side of the data line 12.

[0057] Optionally, the touch control trace 15 is arranged between the first pixel electrode column and the third pixel electrode column, such as can be arranged between the blue sub-pixel column and the red sub-pixel column, so that the number of the touch control trace 15 is 1 / 3 of the number of the data line 12, the number of the touch control trace 15 is reduced, and the aperture ratio is improved.

[0058] In some embodiments, as Figure 5 Optionally, in some embodiments, the touch control trace 15 includes a first segment extending along the extension direction of the data line 12 and a second segment bypassing the thin film transistor 16, and the first segment and the second segment are alternately connected in the extension direction of the data line 12. The first segment is arranged in overlap with the data line 12.

[0059] In which, the touch control trace 15 and the data line 12 are partially overlapped, which can save the wiring area of the touch control trace 15, and further improve the aperture ratio.

[0060] Optionally, the touch wire 15, the scan line 11 and the data line 12 can each be formed of a metal element selected from chromium, copper, aluminum, gold, silver, zinc, molybdenum, tantalum, titanium, tungsten, manganese, nickel, iron, neodymium, cobalt, an alloy containing any of the above metal elements, or an alloy combining any of the above metal elements.

[0061] In the display panel 100 of the embodiment of the present application, the film layer positions corresponding to the scan line 11, the data line 12, the touch wire 15, the pixel electrode 13, the common electrode 14 and the thin film transistor 16 are not specifically limited, as long as the display and touch functions can be realized. Figure 2 The display panel 100 shown is only one film layer level architecture of the embodiment of the present application, which is described below with the example of Figure 2 but is not limited thereto.

[0062] Optionally, the touch wire 15 and the light shielding layer 15s are arranged in the same layer and formed in the first metal layer, the light shielding layer 15s is used to shield the thin film transistor 16, the scan line 11 is formed in the second metal layer, the data line 12 and the first adapter line 121 are formed in the third metal layer, and an insulating layer is arranged between adjacent two metal layers.

[0063] In some embodiments of the present application, a thin film transistor 16 is arranged in a pixel region 10a and connected to a pixel electrode 13. In the same pixel region 10a, the via group 15a is located in a corner region of the pixel region 10a away from the thin film transistor 16 and close to the touch wire 15, and the touch wire 15 is located on one side of the data line 12 close to the via group 15a.

[0064] It can be understood that, in addition, the via group 15a away from the thin film transistor 16 can reduce the process difficulty and save the layout space, the via group 15a close to the touch wire 15 and located in the corner region of the pixel region 10a can shorten the connection distance between the via group 15a and the touch wire 15, thereby improving the light transmittance; secondly, the touch wire 15 located on one side of the data line 12 close to the via group 15a can avoid the connection of the touch wire 15 and the via group 15a across the data line 12; in addition, the continuity of the first electrode 13a can be ensured, and the display uniformity can be improved.

[0065] Optionally, in some embodiments of the present application, the ratio of the number of all first electrodes 13a to the number of all first pixel electrodes 131 is less than 6:94.

[0066] It can be understood that, based on the small area of the first electrode 13a, the more the number of the first electrode 13a, the smaller the entire light transmission area of the display panel 100, and the lower the aperture ratio, but the more the number of the via group 15a connected by the common electrode 14 and the touch control wire 15, and the better the connection stability of the common electrode 14 and the touch control wire 15. The smaller the number of the first electrode 13a, the larger the entire light transmission area of the display panel 100, the higher the aperture ratio, and the weaker the connection stability of the common electrode 14 and the touch control wire 15. Therefore, based on the comprehensive consideration of the light transmission, the aperture ratio and the connection stability, the ratio of the number of all the first electrodes 13a to the number of all the first pixel electrodes 131 is less than 6:94.

[0067] For example, the ratio of the number of all the first electrodes 13a to the number of all the first pixel electrodes 131 can be 6:95, 6:96, 6:97, 6:98, 6:99, 6:100, 5:95, 5:96, 5:97, 5:98, 5:99, 5:100, 4:95, 4:96, 4:97, 4:98, 4:99, 4:100, 3:95, 3:96, 3:97, 3:98, 3:99, 3:100, 2:95, 2:96, 2:97, 2:98, 2:99, 2:100, and the like.

[0068] Optionally, the touch control wire 15 is connected to the common electrode 14 through a set number of via groups 15a, and the plurality of via groups 15a are uniformly arranged, and the set number is between 2 and 15.

[0069] It can be understood that, the more the number of the via group 15a, the better the connection stability of the common electrode 14 and the touch control wire 15, but the larger the space area occupied, and the lower the light transmission of the display panel 100; the fewer the number of the via group 15a, the weaker the connection stability of the common electrode 14 and the touch control wire 15, but the smaller the space area occupied, and the higher the light transmission of the display panel 100.

[0070] Therefore, based on the above consideration, the touch control wire 15 is connected to the common electrode 14 through 2 to 15 via groups 15a, so as to balance the connection stability of the common electrode 14 and the touch control wire 15, and the light transmission and aperture ratio of the display panel 100. In addition, the via group 15a is arranged in a uniform manner, which can improve the display uniformity of the display panel 100.

[0071] Optionally, the set number can be 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14 or 15.

[0072] Optionally, the ratio of the number of all first electrodes 13a to the number of all first pixel electrodes 131 is less than or equal to 3:97, so as to improve the transmittance and aperture ratio of the display panel 100 while ensuring the stability of the connection between the common electrode 14 and the touch wire 15.

[0073] In some embodiments of the present application, the area of the first electrode 13a is greater than or equal to 90% of the area of the second electrode 13b.

[0074] It can be understood that the larger the area of the first electrode 13a is, the higher the transmittance and aperture ratio of the pixel area 10a are. Therefore, the area of the first electrode 13a is defined to be greater than or equal to 9% of the area of the second electrode 13b to avoid the overall transmittance and aperture ratio being too small.

[0075] Optionally, the area of the first electrode 13a can be 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98% or 99% of the area of the second electrode 13b.

[0076] Optionally, the area of the first electrode 13a is greater than or equal to 95% of the area of the second electrode 13b, so as to better improve the transmittance and aperture ratio of the display panel 100.

[0077] In some embodiments of the present application, the opposite substrate 20 comprises a black matrix layer 21 covering the scan lines 11, the data lines 12, the touch wire 15, the thin film transistor 16 and the via group 15a. The black matrix layer 21 is provided with a plurality of openings 21a, and each opening 21a is arranged directly above a pixel electrode 13.

[0078] The area of the opening 21a corresponding to the first electrode 13a is a first area s1, and the area of the opening 21a corresponding to the second electrode 13b is a second area s2, s1

[0079] It can be understood that, based on the area of the first electrode 13a being smaller than the area of the second electrode 13b, and the via group 15a being in the same pixel area 10a as the first electrode 13a, s1 < s2. Wherein, the smaller the area of the first electrode 13a, the larger the area of the via group 15a, the smaller the area of the opening 21a corresponding to the first electrode 13a; the larger the area of the first electrode 13a, the smaller the area of the via group 15a, the larger the area of the opening 21a corresponding to the first electrode 13a, therefore, based on the consideration of the aperture ratio and the stability of the connection of the via group 15a, (s2-s1) < s2·10% is selected, such as (s2-s1) = s2·9%, (s2-s1) = s2·8%, (s2-s1) = s2·7%, (s2-s1) = s2·6%, (s2-s1) = s2·5%, (s2-s1) = s2·4%, (s2-s1) = s2·3% or (s2-s1) = s2·2%, etc.

[0080] Optionally, in order to improve the aperture ratio while reducing the risk of displaying vertical lines, (s2-s1) ≤ s2·5% can be selected.

[0081] In some embodiments of the present application, the display panel 100 further comprises a spacer 17 configured to support the opposite substrate 20. In the display panel 100 from the top view, the spacer 17 is located at the intersection of the scan line 11 and the data line 12, and a via group 15a is arranged adjacent to or partially overlaps with a spacer 17.

[0082] The black matrix layer 21 comprises a light shielding part 211 covering the intersection. In the display panel 100 from the top view, a light shielding part 211 covers both the spacer 17 and the via group 15a.

[0083] It can be understood that, by arranging the via group 15a close to the spacer 17 or partially overlapping with the spacer 17, the two are gathered together, so that the light shielding part 211 can cover the spacer 17 and the via group 15a with a smaller area to provide the aperture ratio.

[0084] Optionally, in some embodiments of the present application, in the extension direction of the scan line 11, two adjacent spacers 17 are spaced apart by at least one of the intersections. In the extension direction of the data line 12, two adjacent spacers 17 are spaced apart by at least one of the intersections.

[0085] It can be understood that, by arranging the spacer 17 to be spaced apart by at least one of the intersections in the extension direction of the scan line 11 and in the extension direction of the data line 12, at least half the number of spacers 17 can be saved, thereby saving a corresponding number of light shielding parts 211 to improve the aperture ratio.

[0086] Optionally, the spacers 17 are spaced apart from each other by one of the intersections in the extending direction of the scan lines 11 and in the extending direction of the data lines 12, so that only two of the four corner regions of each pixel region 10a are provided with a spacer 17.

[0087] Optionally, in some embodiments, as shown in FIG. 1C, the spacers 17 can be spaced apart from each other by three of the intersections in the extending direction of the scan lines 11 and by one of the intersections in the extending direction of the data lines 12, so that only one of the four corner regions of each pixel region 10a is provided with a spacer 17, to save more light shielding portions 211.
