[0051] The following description of each embodiment refers to the attached drawings, which are used to illustrate specific embodiments in which the present application can be implemented. The directional terms mentioned in the present application, such as [up], [down], [front], [back], [left], [right], [inside], [outside], [side], etc., only refer to the directions of the attached drawings. Therefore, the directional terms used are for explaining and understanding the present application, rather than for limiting the present application. In the drawings, structurally similar units are denoted by the same reference numerals. In the drawings, for the sake of clear understanding and convenient description, the thicknesses of some layers and regions are exaggerated. That is, the dimensions and thicknesses of each component shown in the drawings are arbitrarily shown, but the present application is not limited thereto.

[0052] Regarding the problem of color deviation difference in the left and right viewing angles of existing touch display panels, the inventors of the present application found in the research that: referring to Figures 1 to 5b , Figure 1 illustrates a schematic diagram of the planar structure arrangement of touch signal lines. In Figure 1 , each data line DL' corresponds to a touch signal line TP', so that each sub-pixel corresponds to a touch signal line TP'. It should be noted that in the present application, the sub-pixels are characterized by the color resist blocks 21' of the color filter layer. One color resist block 21' represents one sub-pixel. The area where the color resist block 21' is located represents the opening range of the sub-pixel, that is, the size of the color resist block 21' represents the size of the sub-pixel opening SPO'. The color resist block 21' and the sub-pixel opening SPO' are arranged in one-to-one correspondence. The color of the color resist block 21' represents the color presented by the corresponding sub-pixel, that is, the color displayed by the sub-pixel opening SPO'. The color resist block 21' includes a first-color color resist block 21-1', a second-color color resist block 21-2', and a third-color color resist block 21-3'. Among them, the first-color color resist block 21-1', the second-color color resist block 21-2', and the third-color color resist block 21-3' are defined as R', G', and B' respectively. That is, the first-color color resist block 21-1', the second-color color resist block 21-2', and the third-color color resist block 21-3' are a red color resist block R', a green color resist block G', and a blue color resist block B' respectively.

[0053] In order to improve the aperture ratio of the touch display panel and reduce costs, more and more touch display panels adopt a touch design scheme in which three sub-pixels share one touch signal line TP', and the touch signal lines TP' are all fixedly arranged between a certain two sub-pixels, such as Figure 2a , Figure 2b and Figure 2c , Figure 2a , Figure 2b , Figure 2c respectively illustrate a schematic diagram of the planar structure arrangement of a touch signal line TP'. Among them, Figure 2aThe touch signal line TP' therein is arranged between the first color resist block 21-1' and the second color resist block 21-2'. Figure 2b The touch signal line TP' therein is arranged between the second color resist block 21-2' and the third color resist block 21-3'. Figure 2c The touch signal line TP' therein is arranged between the third color resist block 21-3' and the first color resist block 21-1'. However, this design has the problem of color cast difference in the left and right viewing angles.

[0054] Specifically, referring to Figures 3 to 5b , Figure 3 illustrates the viewing field range when viewing the touch display panel head-on. Figure 4 illustrates a schematic diagram of the correspondence between the data line DL' and the touch signal and the black matrix. Figure 5a illustrates a comparison schematic diagram of the opening loss of each color resist block from the right viewing angle. Figure 5b illustrates a comparison schematic diagram of the opening loss of each color resist block from the left viewing angle. Referring to Figure 3 , for a touch display panel with a relatively large size such as a tablet, even when viewing the center of the screen of the touch display panel 100' head-on, there will actually be a certain viewing angle for the left and right edges of the screen. This will result in inconsistent color cast directions in the left and right viewing angles, and the sensory presentation will be similar to a poor taste such as pink on the left and cyan on the right or blue on the left and yellow on the right.

[0055] Referring to Figure 4 , taking the touch signal line TP' located between the first color resist block 21-1' and the second color resist block 21-2' as an example, the color filter layer further includes a black matrix located between the color resist blocks. The black matrix includes a first light-shielding portion 221' and a second light-shielding portion 222'. The first light-shielding portion 221' shields the data line DL' at the position without the touch signal line TP'. The second light-shielding portion 222' shields the data line DL' at the position with the touch signal line TP' and the corresponding touch signal line TP'. The orthographic projection of the data line DL' at the position without the touch signal line TP' on the first light-shielding portion 221' and the outer boundary of the first light-shielding portion 221' have a first distance L1'. The first distance L1' is also the shielding distance of the first light-shielding portion 221' for the data line DL'. The orthographic projection of the data line DL' at the position with the touch signal line TP' and the corresponding touch signal line TP' on the second light-shielding portion 222' and the outer boundary of the second light-shielding portion 222' have a second distance L2'. The second distance L2' is also the shielding distance of the second light-shielding portion 222' for the data line DL' and the touch signal line TP'. Among them, the second distance L2' is less than the first distance L1'.

[0056] When the viewing angle is small, since the second distance L2' is less than the first distance L1', when looking right, when the metal (including the data line DL' and the corresponding touch signal line TP') between the first color color resistance block 21-1' and the second color color resistance block 21-2' starts to block the opening of the second color color resistance block 21-2', the data line DL' between the first color color resistance block 21-1' and the third color color resistance block 21-3' is not blocked yet. This makes the aperture ratio loss of the second color color resistance block 21-2' greater than that of the first color color resistance block 21-1' and the third color color resistance block 21-3', showing a pinkish visual appearance. Similarly, when looking left, the aperture ratio loss of the first color color resistance block 21-1' is greater than that of the second color color resistance block 21-2' and the third color color resistance block 21-3', showing a bluish visual color.

[0057] Referring to Figure 5a and Figure 5b , when the viewing angle is large, since the touch signal lines TP' are all routed between two fixed color resistance blocks, for example, between the first color color resistance block 21-1' and the second color color resistance block 21-2', the metal line width (including the line width of the touch signal line TP' and the corresponding data line DL') at the location where the touch signal line TP' is provided is greater than the metal line width at the location of a single data line DL' (only the data line DL'). This makes the light blocking distance of the metal between different color resistance blocks different, and the screen will also have a taste abnormality of different degrees of color deviation from left to right.

[0058] Therefore, the present application provides a display panel and a display device to improve the color deviation difference formed by different fixed sub-pixels with large aperture losses under left and right viewing angles.

[0059] Please refer to Figures 1 to 9 , Figure 6 which is a partial cross-sectional structure schematic diagram of the display panel provided by the embodiment of the present application, Figure 7 which is a partial cross-sectional structure schematic diagram of the first substrate provided by the embodiment of the present application, Figure 8 which is a first planar layout schematic diagram of the touch signal line provided by the embodiment of the present application, Figure 9 which is a comparison schematic diagram of the light blocking distances of the black matrix for the data line and the touch signal line. Referring to Figures 6 to 8 , the display panel 100 includes a first substrate 10 and data lines DL and touch signal lines TP that are spaced apart on the first substrate 10. The data lines DL and the touch signal lines TP extend in the same direction, and the number of the data lines DL is greater than the number of the touch signal lines TP. For example, the number of the data lines DL is at least 3 times the number of the touch signal lines TP. The display panel 100 includes a liquid crystal display panel 100, etc. In the embodiment of the present application, the display panel 100 is taken as an example of the liquid crystal display panel 100 for illustration.

[0060] Among them, the display panel 100 further includes a plurality of sub-pixel openings SPO. The plurality of sub-pixel openings SPO are arranged in an opening column in the extending direction of the touch signal line TP. Each touch signal line TP is located between two sub-pixel openings SPO with different display colors, and is located between two adjacent opening columns. Moreover, the display colors of two adjacent sub-pixel openings SPO in each opening column are different.

[0061] In this way, at least two sub-pixels with different colors are affected by the opening at the left viewing angle and the right viewing angle, and they are not fixed to sub-pixels of one color. Moreover, one of the two sub-pixels with different colors affected by the opening at the left viewing angle is the same as one of the two sub-pixels with different colors affected by the opening at the right viewing angle. Therefore, the color cast difference formed by the different fixed sub-pixels with large opening loss at the left and right viewing angles can be improved.

[0062] In some embodiments, the display panel 100 further includes a color filter layer 20. The color filter layer 20 is disposed on a side of the data line DL and the touch signal line TP away from the first substrate 10. The color filter layer 20 includes a plurality of color resist blocks 21 arranged at intervals and a black matrix 22 located between adjacent color resist blocks 21. The color resist blocks 21 are arranged in a color resist column in the extending direction of the touch signal line TP, and the color resist blocks 21 are arranged in one-to-one correspondence with the sub-pixel openings SPO. The data line DL and the touch signal line TP are arranged corresponding to the black matrix 22.

[0063] It should be noted that in the present application, the sub-pixels are represented by the color resist blocks 21 of the color filter layer 20. One color resist block 21 represents one sub-pixel. The area where the color resist block 21 is located represents the opening range of the sub-pixel, that is, the size of the color resist block 21 represents the size of the sub-pixel opening SPO. The color resist blocks 21 are arranged in one-to-one correspondence with the sub-pixel openings SPO. The color of the color resist block 21 represents the color presented by the corresponding sub-pixel, that is, the color displayed by the sub-pixel opening SPO.

[0064] Among them, in the front view of the display panel 100, each touch signal line TP is located between two color resist blocks 21 with different colors, and is located between two adjacent color resist columns. Moreover, the colors of two adjacent color resist blocks 21 in each color resist column are different. For example, each touch signal line TP is located in two color resist columns between two adjacent color resist columns, and the colors of two adjacent color resist blocks 21 in each color resist column are different.

[0065] In this way, the sub-pixels affected by the opening in the left viewing angle and the right viewing angle are at least two sub-pixels with different colors, and will not be fixed to a sub-pixel of one color. Moreover, one of the two sub-pixels with different colors affected by the opening in the left viewing angle has the same color as one of the two sub-pixels with different colors affected by the opening in the right viewing angle, thereby improving the color cast difference formed by the different fixed sub-pixels with large opening losses in the left and right viewing angles.

[0066] Optionally, each of the touch signal lines TP is located between two adjacent color filter columns, and the colors of three adjacent color filter blocks 21 in each color filter column are different. In this way, the sub-pixels affected by the opening in the left viewing angle and the right viewing angle are all three sub-pixels with different colors, and will not be fixed to a sub-pixel of one color. Moreover, the three sub-pixels with different colors affected by the opening in the left viewing angle are the same as the three sub-pixels with different colors affected by the opening in the right viewing angle, thereby better improving the color cast difference formed by the different fixed sub-pixels with large opening losses in the left and right viewing angles.

[0067] Specifically, referring to Figure 6 and Figure 7 , the display panel 100 further includes a first substrate 1 and a second substrate 2 which are oppositely arranged, and a liquid crystal layer 3 disposed between the first substrate 1 and the second substrate 2. The color filter layer 20 is formed on one side of the second substrate 2 facing the first substrate 1. Among them, the first substrate 1 is an array substrate, and the second substrate 2 is a color filter substrate.

[0068] The first substrate 1 includes a driving circuit layer disposed on the first substrate 10, and a transparent conductive layer 40 located away from the first substrate 10 of the driving circuit layer. The driving circuit layer includes at least one transistor 30, and the data line DL and the touch signal line TP are disposed on the same layer as the source electrode 33 or the drain electrode 34 of the transistor 30. The transparent conductive layer 40 includes a pixel electrode 41 connected to the transistor 30 and a touch electrode 42 connected to the touch signal line TP.

[0069] The second substrate 2 includes a second substrate 50, and the materials of the second substrate 50 and the first substrate 10 may be the same, such as glass or the like. The color filter layer 20 is located on one side of the second substrate 50 facing the first substrate 1. The second substrate 2 further includes a planar protective layer 51 disposed on one side of the color filter layer 20 facing the first substrate 1.

[0070] The display panel 100 further includes a common electrode layer 60. An electric field is formed between the common electrode layer 60 and the pixel electrode 41 to drive the rotation of liquid crystal molecules in the liquid crystal layer 3. The common electrode layer 60 may be located on the first substrate 1 or the second substrate 2. In the embodiment of the present application, the case where the common electrode layer 60 is located on the first substrate 1 is taken as an example for illustration. Optionally, the common electrode layer 60 is located between the transparent conductive layer 40 and the transistor 30. The material of the common electrode layer 60 may be the same as that of the transparent conductive layer 40, such as transparent conductive materials like Indium Tin Oxide (ITO).

[0071] The first substrate 1 further includes a buffer layer 11 located between the first substrate 10 and the transistor 30. The buffer layer 11 can block the diffusion of impurities and provide a flat top surface for the transistor 30. The transistor 30 includes an active layer 31, a gate 32, a source 33, and a drain 34. A light-shielding layer 80 is further provided on the first substrate 1 on the first substrate 10. The buffer layer 11 covers the light-shielding layer 80 and the first substrate 10. The light-shielding layer 80 is at least provided corresponding to the active layer 31 to shield the active layer 31.

[0072] The first substrate 1 further includes a plurality of insulating layers, such as a gate insulating layer 12 located between the active layer 31 and the gate 32, an interlayer insulating layer 13 located between the gate 32 and the source 33 and the drain 34, a planarization layer 14 located between the source 33, the drain 34 and the common electrode layer 60, and a passivation layer 15 located between the common electrode layer 60 and the transparent conductive layer 40. A first via hole and a second via hole are formed in the passivation layer 15, penetrating through the passivation layer 15, the common electrode layer 60, and the planarization layer 14. The pixel electrode 41 is connected to the drain 34 of the transistor 30 through the first via hole, and the touch electrode 42 is connected to the touch signal line TP through the second via hole. Among them, the common electrode and the touch electrode 42 are both insulated from the common electrode layer 60.

[0073] The pixel electrode 41 is provided corresponding to the color resist block 21, and the area where the color resist block 21 is located is the light-emitting area of the display panel 100. The touch signal line TP and the data line DL are provided corresponding to the black matrix 22, and the area where the black matrix 22 is located is the non-light-emitting area of the display panel 100. The transistor 30 is also provided corresponding to the black matrix 22, and the black matrix 22 is used to block the transistor 30, the data line DL, and the touch signal line TP to avoid reducing the contrast due to reflected light.

[0074] Refer to Figure 8, the data line DL and the touch signal line TP are both arranged at intervals in the first direction X and both extend in the second direction Y. The second direction Y intersects with the first direction X, and the included angle between the first direction X and the second direction Y is greater than 0 degrees and less than or equal to 90 degrees. For example, the first direction X is the horizontal direction, the second direction Y is the vertical direction, and the first direction X and the second direction Y are perpendicular.

[0075] A plurality of the color resist blocks 21 are arranged in a color resist row in the first direction X, and a plurality of the color resist blocks 21 are arranged in a color resist column in the second direction Y. The color resist block 21 includes a first-color color resist block 21-1, a second-color color resist block 21-2, and a third-color color resist block 21-3. On each of the color resist columns, the first-color color resist block 21-1, the third-color color resist block 21-3, and the second-color color resist block 21-2 are alternately arranged in sequence.

[0076] Among them, the first-color color resist block 21-1, the second-color color resist block 21-2, and the third-color color resist block 21-3 are defined as R, G, and B respectively. That is, for the convenience of description and understanding, in this application, R represents the first-color color resist block 21-1, G represents the second-color color resist block 21-2, and B represents the third-color color resist block 21-3. The first-color color resist block 21-1, the second-color color resist block 21-2, and the third-color color resist block 21-3 are a red color resist block R, a green color resist block G, and a blue color resist block B respectively. After the light passes through the first-color color resist block 21-1, it appears red. After the light passes through the second-color color resist block 21-2, it appears green. After the light passes through the third-color color resist block 21-3, it appears blue.

[0077] Optionally, each of the color resist rows includes a plurality of first repeating units. Each of the first repeating units includes 9 color resist blocks, and the 9 color resist blocks include RGBRGBRGB arranged in sequence in the first direction. 3 touch signal lines are arranged in each of the first repeating units.

[0078] Among them, on the same color resist row, among three adjacent touch signal lines TP, each touch signal line TP is located between the adjacent first-color color resist block 21-1 and the second-color color resist block 21-2; or each touch signal line TP is located between the adjacent second-color color resist block 21-2 and the third-color color resist block 21-3; or each touch signal line TP is located between the adjacent third-color color resist block 21-3 and the first-color color resist block 21-1.

[0079] For example, referring to Figure 8, on the color filter row of the first row, among three adjacent touch signal lines TP, each touch signal line TP is located between an adjacent third-color color filter block 21-3 and a first-color color filter block 21-1; on the color filter row of the second row, among three adjacent touch signal lines TP, each touch signal line TP is located between an adjacent second-color color filter block 21-2 and a third-color color filter block 21-3; on the color filter row of the third row, among three adjacent touch signal lines TP, each touch signal line TP is located between an adjacent first-color color filter block 21-1 and a second-color color filter block 21-2.

[0080] That is, on every three adjacent color filter rows, each touch signal line TP is located between an adjacent first-color color filter block 21-1 and a second-color color filter block 21-2 on one color filter row, and is located between an adjacent second-color color filter block 21-2 and a third-color color filter block 21-3 on another color filter row, and is located between an adjacent third-color color filter block 21-3 and a first-color color filter block 21-1 on the third color filter row. Among them, the arrangement order of one color filter row, another color filter row, and the third color filter row is not limited.

[0081] On two adjacent color filter rows, each touch signal line is located between 4 color filter blocks 21, and the 4 color filter blocks 21 include the first-color color filter block 21-1, the second-color color filter block 21-2, and the third-color color filter block 21-3. For example, on Figure 8 the first color filter row and the second color filter row, the second touch signal line TP is located between the third-color color filter block 21-3 and the first-color color filter block 21-1 of the first color filter row, and is located between the second-color color filter block 21-2 and the third-color color filter block 21-3 of the second color filter row. That is, the second touch signal line TP is located between four color filter blocks 21, namely the third-color color filter block 21-3, the first-color color filter block 21-1, the second-color color filter block 21-2, and the third-color color filter block 21-3.

[0082] In this way, in the left viewing angle and the right viewing angle, the sub-pixels with larger aperture ratio loss both include the first-color color filter block 21-1, the second-color color filter block 21-2, and the third-color color filter block 21-3. That is, the sub-pixels with larger aperture ratio loss in the left and right viewing angles are exactly the same, so as to avoid or eliminate the color cast difference formed by different fixed sub-pixels with larger aperture loss in the left and right viewing angles. That is, by adjusting the arrangement of the color filter blocks 21, the touch signal line TP can be positioned periodically between RG, RB, and GB as a whole, which can avoid the viewing angle color cast taste problem caused by the fixed position of the touch signal line TP to the greatest extent.

[0083] In some embodiments, within each of the repeating units RU1, at least two color resist blocks 21 are provided between two adjacent touch signal lines TP, so that the touch signal lines TP are relatively evenly distributed. Optionally, three color resist blocks 21 are provided between each two adjacent touch signal lines TP.

[0084] From Figure 8 As can be seen from the arrangement of the touch signal lines TP described above, in the left viewing angle, the sub-pixels in each first repeating unit RU1 that are greatly affected by the touch signal lines TP and result in large aperture losses include RGB. In the right viewing angle, the sub-pixels in each first repeating unit RU1 that are greatly affected by the touch signal lines TP and result in large aperture losses also include RGB. In this way, the colors of the sub-pixels with large aperture losses in the left and right viewing angles are the same, thereby avoiding or eliminating the color cast difference formed by different fixed sub-pixels with large aperture losses in the left and right viewing angles. That is, by adjusting the arrangement of the color resist blocks 21, the positions of the touch signal lines TP are periodically located between RG, RB, and GB as a whole, which can avoid the viewing angle color cast and taste problems caused by the fixed positions of the touch signal lines TP to the greatest extent.

[0085] Referring to Figure 6 and Figure 9 , the black matrix 22 includes a first light-shielding portion 221 that separately shields the data line DL and a second light-shielding portion 222 that shields the data line DL and the touch signal line TP. There is a first distance L1 between the outer boundary of the first light-shielding portion 221 and the orthographic projection of the data line DL on the first light-shielding portion 221. The first distance L1 is also the shielding distance of the first light-shielding portion 221 for the data line DL at the position where the touch signal line TP is not provided. There is a second distance L2 between the outer boundary of the second light-shielding portion 222 and the orthographic projections of the data line DL and the touch signal line TP at the position where the touch signal line TP is provided on the second light-shielding portion 222. The second distance L2 is also the shielding distance of the second light-shielding portion 222 for the data line DL and the touch signal line TP at the position where the touch signal line TP is provided.

[0086] In some embodiments, the first distance L1 is greater than the second distance L2. In some other embodiments, the first distance L1 is equal to the second distance L2. To make the first distance L1 equal to the second distance L2, the line width of the data line DL corresponding to the first light-shielding portion 221 can be made greater than the line width of the data line DL corresponding to the second light-shielding portion 222. Of course, the first distance L1 can also be made equal to the second distance L2 by other means, such as by adjusting the line width of the data line DL at the position where the touch signal line TP is not provided; or by adjusting the line width of the data line DL at the position where the touch signal line TP is provided; or by adjusting the line width of the touch signal line TP; or by simultaneously adjusting the line width of the touch signal line TP and the line width of the data line DL.

[0087] Whether the first distance L1 and the second distance L2 are equal does not affect the improvement of the color cast difference formed by different fixed sub-pixels with large aperture loss under the left and right viewing angles in the embodiments of the present application. That is, the effect of improving the color cast difference formed by different fixed sub-pixels with large aperture loss under the left and right viewing angles by adjusting the position of the touch signal line TP in the color resist block 21 of the present application is not affected by the relationship between the first distance L1 and the second distance L2.

[0088] In some embodiments, referring to Figures 1 to 10 , Figure 10 is the second planar layout schematic diagram of the touch signal line provided by the embodiments of the present application. Referring to Figure 10 , different from the embodiment exemplified in Figure 8 , among two adjacent touch signal lines TP on the same color resist row, one touch signal line TP is located between the adjacent first color resist block 20-1 and the second color resist block 20-2, and the other touch signal line TP is located between the adjacent second color resist block 20-2 and the third color resist block 20-3, or the other touch signal line TP is located between the adjacent third color resist block 20-3 and the first color resist block 20-1.

[0089] Optionally, among three adjacent touch signal lines TP on the same color resist row, one touch signal line TP is located between the adjacent first color resist block 20-1 and the second color resist block 20-2, another touch signal line TP is located between the adjacent second color resist block 20-2 and the third color resist block 20-3, and the third touch signal line TP is located between the adjacent third color resist block 20-3 and the first color resist block 20-1.

[0090] Referring toFigure 10 In the first repeating unit RU1 on the color resistance row described in the second row, among the three adjacent touch signal lines TP, the first touch signal line TP is located between the adjacent second-color color resistance blocks 20-2 and 20-3, the second touch signal line TP is located between the adjacent first-color color resistance blocks 20-1 and 20-2, and the third touch signal line TP is located between the adjacent third-color color resistance blocks 20-3 and 20-1.

[0091] From Figure 10 the arrangement of the touch signal lines TP described above, it can be seen that in the left viewing angle, the sub-pixels in each first repeating unit RU1 that are greatly affected by the touch signal lines TP and result in large aperture losses include RGB, and in the right viewing angle, the sub-pixels in each first repeating unit RU1 that are greatly affected by the touch signal lines TP and result in large aperture losses also include RGB. In this way, the colors of the sub-pixels with large aperture losses in the left and right viewing angles are the same, so that the color cast difference formed by different fixed sub-pixels with large aperture losses in the left and right viewing angles can be avoided or eliminated. For other descriptions, please refer to the above embodiments and will not be elaborated here.

[0092] In some embodiments, referring to Figures 11 to 12b , Figure 11 FIG. is the third schematic plan view of the touch signal lines provided by the embodiment of the present application, Figure 12a FIG. is a schematic diagram of the comparison of the shielding distances of the data line DL and the touch signal line TP by the black matrix 22 when the touch signal line TP is fixedly arranged between RG, Figure 12b FIG. is a schematic diagram of the comparison of the shielding distances of the data line DL and the touch signal line TP by the black matrix 22 when the touch signal line TP is fixedly arranged between GB, Figure 12c FIG. is a schematic diagram of the comparison of the shielding distances of the data line DL and the touch signal line TP by the black matrix 22 when the touch signal line TP is fixedly arranged between BR. Referring to Figure 11 and Figure 12a the touch signal line TP is fixedly arranged between the first-color color resistance block 21-1 and the second-color color resistance block 21-2, and the first distance L1 is equal to the second distance L2.

[0093] Specifically, referring to Figure 11 the data line DL and the touch signal line TP are both arranged at intervals in the first direction X and both extend in the second direction Y. The second direction Y intersects with the first direction X, and the included angle between the first direction X and the second direction Y is greater than 0 degree and less than or equal to 90 degrees. For example, the first direction X is the horizontal direction, the second direction Y is the vertical direction, and the first direction X and the second direction Y are perpendicular.

[0094] A plurality of the color resistance blocks 21 are arranged in a color resistance row in the first direction X, and a plurality of the color resistance blocks 21 are arranged in a color resistance column in the second direction Y. The plurality of the color resistance blocks 21 on each color resistance row include a first color resistance block 21-1, a second color resistance block 21-2, and a third color resistance block 21-3, and the colors of the plurality of the color resistance blocks 21 on each color resistance column are the same.

[0095] Wherein, the first color resistance block 21-1, the second color resistance block 21-2, and the third color resistance block 21-3 are defined as R, G, and B respectively. That is, for the convenience of description and understanding, in this application, R represents the first color resistance block 21-1, G represents the second color resistance block 21-2, and B represents the third color resistance block 21-3. The first color resistance block 21-1, the second color resistance block 21-2, and the third color resistance block 21-3 are a red color resistance block 21, a green color resistance block 21, and a blue color resistance block 21 respectively. After the light passes through the first color resistance block 21-1, it appears red. After the light passes through the second color resistance block 21-2, it appears green. After the light passes through the third color resistance block 21-3, it appears blue.

[0096] Every three columns of the color resistance columns correspond to one touch signal line TP. The touch signal line TP is fixedly arranged between the first color resistance block 21-1 and the second color resistance block 21-2, that is, both sides of each touch signal line TP are provided with the first color resistance block 21-1 and the second color resistance block 21-2.

[0097] Refer to Figure 12a , the black matrix 22 includes a first light-shielding portion 221 that separately shields the data line DL, and a second light-shielding portion 222 that shields the data line DL and the touch signal line TP. There is a first distance L1 between the orthographic projection of the data line DL on the first light-shielding portion 221 and the outer boundary of the first light-shielding portion 221. The first distance L1 is also the shielding distance of the first light-shielding portion 221 for the data line DL at the position where the touch signal line TP is not provided; there is a second distance L2 between the orthographic projections of the data line DL and the touch signal line TP at the position where the touch signal line TP is provided on the second light-shielding portion 222 and the outer boundary of the second light-shielding portion 222. The second distance L2 is also the shielding distance of the second light-shielding portion 222 for the data line DL and the touch signal line TP at the position where the touch signal line TP is provided.

[0098] The first distance L1 is equal to the second distance L2. To make the first distance L1 equal to the second distance L2, the line width of the data line DL corresponding to the first light-shielding portion 221 can be made greater than the line width of the data line DL corresponding to the second light-shielding portion 222. Of course, the first distance L1 equal to the second distance L2 can also be achieved by other means, such as by adjusting the line width of the data line DL at the position where the touch signal line TP is not provided; or by adjusting the line width of the data line DL at the position where the touch signal line TP is provided; or by adjusting the line width of the touch signal line TP; or by simultaneously adjusting the line width of the touch signal line TP and the line width of the data line DL.

[0099] In some other embodiments, referring to Figure 12b , the touch signal line TP is fixedly arranged between the second color filter block 21-2 and the third color filter block 21-3, and the first distance L1 is equal to the second distance L2; referring to Figure 12c , the touch signal line TP is fixedly arranged between the third color filter block 21-3 and the first color filter block 21-1, and the first distance L1 is equal to the second distance L2. Thus, by adjusting the line width of the touch signal line TP and / or the line width of the data line DL to make the first distance L1 equal to the second distance L2, the color cast difference between the left and right viewing angles at a small viewing angle (such as 0 degrees to 30 degrees) can be improved.

[0100] The effects of the above-mentioned various embodiments in improving the color cast difference between the left and right viewing angles will be further described below through simulation.

[0101] Referring to Figures 13a to 13f , Figure 13a For Figure 1 a schematic diagram of the chromaticity viewing angle curve corresponding to the example arrangement manner of the touch signal line TP, Figure 13b For Figure 2a a schematic diagram of the chromaticity viewing angle curve corresponding to the example arrangement manner of the touch signal line TP, Figure 13c For Figure 2b a schematic diagram of the chromaticity viewing angle curve corresponding to the example arrangement manner of the touch signal line TP, Figure 13d For Figure 2c a schematic diagram of the chromaticity viewing angle curve corresponding to the example arrangement manner of the touch signal line TP, Figure 13e This is a schematic diagram of the chromaticity viewing angle curve corresponding to the arrangement manner of the touch signal line TP provided by the embodiment of the present application when the shielding distance of the black matrix 22 is different, Figure 13f This is a schematic diagram of the chromaticity viewing angle curve corresponding to the arrangement manner of the touch signal line TP provided by the embodiment of the present application when the shielding distances of the black matrix 22 are the same. Among them, at Figures 13a to 13fAmong them, the abscissa represents the value of chromaticity x, the ordinate represents the value of chromaticity y, curve A represents the chromaticity view angle curve under the left view angle, curve B represents the chromaticity view angle curve under the right view angle, and the left view angle and the right view angle both select the view angle range from 0 degrees to 75 degrees.

[0102] Comparison Figure 13e and 13f It can be seen that regardless of whether the first distance L1 and the second distance L2 are equal, the change trends of the left view chromaticity curve and the right view chromaticity curve are consistent, that is, whether the first distance L1 and the second distance L2 are equal does not affect the color cast difference formed by the different fixed sub-pixels with large aperture losses under the left and right view angles. In other words, the effect of improving the color cast difference formed by the different fixed sub-pixels with large aperture losses under the left and right view angles by adjusting the arrangement of the color resistance block 21 in this application is not affected by the relationship between the first distance L1 and the second distance L2.

[0103] Comparison Figure 13e , Figure 13f with Figure 13a It can be seen that by adjusting the arrangement of the color resistance block 21 in this application, the same view angle effect as the Figure 1 example of the touch signal line TP arrangement method can be achieved.

[0104] Comparison Figure 13e , Figure 13f with Figure 13b , Figure 13c , Figure 13d It can be seen that in Figure 13b , Figure 13c , Figure 13d , as the view angle increases, there are obvious differences in the color point drift between the left view and the right view, while in Figure 13e , Figure 13f , as the view angle increases, the color point drift between the left view and the right view is basically the same. It can be seen that by adjusting the arrangement of the color resistance block 21 in this application, the touch signal line TP is positioned periodically between RG, RB, and GB as a whole, which can avoid the view angle color cast taste problem caused by the fixed position of the touch signal line TP to the greatest extent.

[0105] Referring to Figures 14a to 14f , Figure 14a is Figure 2a a schematic diagram of the chromaticity view angle curve corresponding to the touch signal line TP arrangement method in the example when the light shielding distance of the black matrix 22 is different, Figure 14b is Figure 2b a schematic diagram of the chromaticity view angle curve corresponding to the touch signal line TP arrangement method in the example when the light shielding distance of the black matrix 22 is different, Figure 14c is Figure 2cSchematic diagram of chromaticity viewing angle curves corresponding to different light-shielding distances of the black matrix 22 for the exemplary arrangement of touch signal lines TP Figure 14d is Figure 12a Schematic diagram of chromaticity viewing angle curves corresponding to the same light-shielding distance of the black matrix 22 for the exemplary arrangement of touch signal lines TP Figure 14e is Figure 12b Schematic diagram of chromaticity viewing angle curves corresponding to the same light-blocking distance of the black matrix 22 for the exemplary arrangement of touch signal lines TP Figure 14f is Figure 12c Schematic diagram of chromaticity viewing angle curves corresponding to the same light-blocking distance of the black matrix 22 for the exemplary arrangement of touch signal lines TP. Among them, in Figures 14a to 14f , the abscissa is the value of chromaticity x, the ordinate is the value of chromaticity y, curve A represents the chromaticity viewing angle curve under the left viewing angle, curve B represents the chromaticity viewing angle curve under the right viewing angle, and both the left viewing angle and the right viewing angle are selected in the small viewing angle range of 0 degrees to 30 degrees.

[0106] Comparing Figure 14d with Figure 14a it can be seen that when the touch signal line TP is fixedly arranged between RG, by adjusting the line width of the touch signal line TP and / or the line width of the data line DL to make the first distance L1 equal to the second distance L2, in the small viewing angle range of 0 degrees to 30 degrees, the difference in the drift direction and amplitude of the color points under the left and right viewing angles is significantly reduced, and the color points are basically the same at the same viewing angle on the left and right, which can significantly improve the color cast difference between the left and right viewing angles at a small viewing angle (such as 0 degrees to 30 degrees).

[0107] Comparing Figure 14e with Figure 14b it can be seen that when the touch signal line TP is fixedly arranged between GB, by adjusting the line width of the touch signal line TP and / or the line width of the data line DL to make the first distance L1 equal to the second distance L2, in the small viewing angle range of 0 degrees to 30 degrees, the difference in the drift direction and amplitude of the color points under the left and right viewing angles is significantly reduced, and the color points are basically the same at the same viewing angle on the left and right, which can significantly improve the color cast difference between the left and right viewing angles at a small viewing angle (such as 0 degrees to 30 degrees).

[0108] Comparing Figure 14f with Figure 14c it can be seen that when the touch signal line TP is fixedly arranged between BR, by adjusting the line width of the touch signal line TP and / or the line width of the data line DL to make the first distance L1 equal to the second distance L2, in the small viewing angle range of 0 degrees to 30 degrees, the difference in the drift direction and amplitude of the color points under the left and right viewing angles is significantly reduced, and the color points are basically the same at the same viewing angle on the left and right, which can significantly improve the color cast difference between the left and right viewing angles at a small viewing angle (such as 0 degrees to 30 degrees).

[0109] Based on the same inventive concept, an embodiment of the present application further provides a display device. Refer to Figures 1 to 15 , Figure 15 which is a schematic plan view of the display device provided by an embodiment of the present application. Refer to Figure 15 , the display device 1000 includes a housing 200 and a display panel 100 installed in the housing 200. The display panel 100 is the display panel 100 described in one of the foregoing embodiments. The display device 1000 may be a device with a display screen such as a mobile phone, a television, a tablet computer, a computer monitor, a digital camera, a game device, a vehicle navigator, an electronic billboard, an automated teller machine, a wearable device, etc. The wearable device may be a smart bracelet, smart glasses, a smart watch, a smart ornament, etc.

[0110] It can be known from the above embodiments that:

[0111] In a display panel and a display device provided by the present application, the display panel includes data lines and touch signal lines arranged at intervals on a first substrate. The data lines and the touch signal lines extend in the same direction. The number of data lines is at least three times the number of touch signal lines. The color filter layer includes a plurality of color resist blocks arranged at intervals and a black matrix located between adjacent color resist blocks. The data lines and the touch signal lines are arranged corresponding to the black matrix. The plurality of color resist blocks are arranged in color resist columns in the extending direction of the touch signal lines. In a front view angle of the display panel, each touch signal line is located between two color resist blocks with different colors and between two adjacent color resist columns. And in each color resist column, two adjacent color resist blocks have different colors. Thus, at least two sub-pixels with different colors whose apertures are affected in the left view angle and the right view angle are not fixed to sub-pixels of one color. Moreover, one of the two sub-pixels with different colors whose apertures are affected in the left view angle is the same as one of the two sub-pixels with different colors whose apertures are affected in the right view angle. Therefore, the color cast difference formed by the different fixed sub-pixels with large aperture loss in the left and right view angles can be improved.
