[0077] Exemplarily, pitch2 is set as the width of the pixel island along the extension direction of the gate line 20, m is the number of sub-pixels included in a row of sub-pixels in the pixel island along the extension direction of the gate line 20, then i=pitch2 / m, i is the width of a sub-pixel along the extension direction of the gate line 20.

[0087] In more detail, one sub-pixel row may correspond to one gate line 20 or two gate lines 20. In the case where each sub-pixel row corresponds to two gate lines 20, the odd-numbered sub-pixels in the sub-pixel row may be coupled to one corresponding gate line 20, and the even-numbered sub-pixels in the sub-pixel row may be coupled to another corresponding gate line 20, but the present invention is not limited thereto.

[0096] In the display substrate 80 provided in the above embodiment, by setting the common electrode to be reused as the touch electrode 50, not only the touch function is integrated into the display substrate 80, but also the additional process of manufacturing the touch electrode 50 is avoided, which effectively simplifies the manufacturing process of the display substrate 80 and reduces the manufacturing cost.

[0097] like Figure 5 As shown, in some embodiments, the display substrate 80 further includes: a virtual data line Dum, the virtual data line Dum is located between adjacent data lines 10 , and the virtual data line Dum is multiplexed as the touch signal line 51 .

[0098] Exemplarily, the touch signal line 51 includes a driving signal line, but is not limited thereto.

[0099] In more detail, two adjacent columns of sub-pixels are set to correspond to the same data line 10, so that the saved data line 10 is a virtual data line Dum, and the virtual data line Dum can be used as the touch signal line 51. This avoids adding an additional process for making the touch signal line 51, effectively simplifies the manufacturing process of the display substrate 80, and reduces the manufacturing cost.

[0100] In some embodiments, the virtual data line Dum can be reused as the conductive connection portion.

[0101] like Figure 7 As shown, in some embodiments, the pixel electrode Pix and the second data portion 102 both extend along a first direction, the first data portion 101 extends along a second direction, and the second direction has the angle a with the first direction; the pixel electrode Pix is ​​simultaneously located in at least two pixel opening areas 40 adjacent to each other along the first direction.

[0102] The above-mentioned setting method can realize that the pixel electrode Pix is ​​simultaneously located in at least two adjacent pixel opening areas 40, so that the pixel electrode Pix can span the area between adjacent pixel opening areas 40 in the at least two adjacent pixel opening areas 40, so that in the at least two adjacent pixel opening areas 40, and in the area between adjacent pixel opening areas 40 in the at least two adjacent pixel opening areas 40, a control electric field located between the pixel electrode Pix and the common electrode can be formed, thereby realizing continuous display and high-definition display of the at least two adjacent pixel opening areas 40.

[0103] like Fig.12 As shown, in some embodiments, the base substrate includes a display area 60 and a peripheral area 61 located around the display area 60; the display substrate 80 also includes a touch electrode 50 and a touch signal line 51 coupled through a fourth via Via4; the touch electrode 50 is located in the display area 60; the touch signal line 51 includes a first touch portion 510 and a second touch portion 511 coupled to each other, the first touch portion 510 and the gate line 20 extending in the same direction, at least a portion of the first touch portion 510 is located in the display area 60, the second touch portion 511 is located in the peripheral area 61, and the extension direction of the second touch portion 511 intersects with the extension direction of the first touch portion 510.

[0104] Need to explain, Fig.12 Only the layout of the touch signal lines 51 in the upper half is shown, and the layout of the touch signal lines 51 in the lower half is the same as that in the upper half.

[0105] Exemplarily, the first touch portion 510 can be shielded by the existing black matrix BM, and there is no need to add an additional black matrix BM to shield the first touch portion 510 .

[0106] like Fig.11 As shown in FIG. 1 , it is illustrated that most of the touch signal lines 51 in the related art are arranged in the display area 60 . This arrangement will affect the aperture ratio of the display substrate 80 .

[0107] In the display substrate 80 provided in the above embodiment, the touch signal line 51 is arranged to include the first touch portion 510 and the second touch portion 511. A portion of the first touch portion 510 is located in the display area 60, and the second touch portion 511 is completely located in the peripheral area 61. This arrangement reduces the influence of the touch signal line 51 on the pixel aperture ratio of the display substrate 80, and effectively improves the pixel aperture ratio of the display substrate 80.

[0108] like Figures 13 to 21As shown, in some embodiments, the touch signal line 51 is located between the touch electrode 50 and the base substrate, or the touch signal line 51 is located on a side of the touch electrode 50 facing away from the base substrate;

[0109] An insulating layer is provided between the touch signal line 51 and the touch electrode 50 , and the touch signal line 51 is coupled to the touch electrode 50 via a via hole penetrating the insulating layer.

[0110] Exemplarily, the insulating layer includes an organic insulating layer 70 or an inorganic insulating layer 71. The insulating layer may be retained on the entire surface or only in the wiring area.

[0111] like Fig.14 and Fig.15 As shown in FIG. 1 , it is shown that the touch signal line 51 is located between the touch electrode 50 and the base substrate, and an organic insulating layer 70 is disposed between the touch signal line 51 and the touch electrode 50. Fig.16 and Fig.17 As shown in FIG. 1 , it is shown that the touch signal line 51 is located between the touch electrode 50 and the base substrate, and an inorganic insulating layer 71 is provided between the touch signal line 51 and the touch electrode 50. Fig.18 and Fig.19 As shown in FIG. 5 , the touch signal line 51 is located on the side of the touch electrode 50 facing away from the base substrate, and an organic insulating layer 70 is disposed between the touch signal line 51 and the touch electrode 50. Fig. 20 and Fig.21 As shown in FIG. 1 , the touch signal line 51 is located on the side of the touch electrode 50 facing away from the base substrate, and an inorganic insulating layer 71 is disposed between the touch signal line 51 and the touch electrode 50 .

[0112] Exemplarily, the organic insulating layer 70 may be a planarizing layer, and the inorganic insulating layer 71 may be a passivation layer, but the present invention is not limited thereto.

[0113] like Figure 1 and Fig.10 As shown, in some embodiments, the display substrate 80 further includes a lens structure Len, which is located on the light-emitting side of the plurality of pixel islands, and the angle between the axial direction of the lens structure Len and the extension direction of the gate line 20 is greater than 0 degrees and less than 90 degrees.

[0114] Need to explain, Figure 1 The polarizer POL is also shown.

[0115] Exemplarily, the lens structure Len includes a plurality of cylindrical lenses distributed in an array, and the axial direction of the lens structure Len is the axial direction of the cylindrical lenses.

[0116] For example, Fig.10 As shown, the axial direction F2 of the lens structure Len is the same as the extending direction (such as the F1 direction) of the pixel electrode Pix, or the same as the extending direction (such as the F1 direction) of the first data portion 101. It should be noted that, Fig.10 The extension direction of the pixel electrode Pix included in the red sub-pixel R, the green sub-pixel G and the blue sub-pixel B is the F1 direction. The RGB rectangular blocks shown in the figure are visual effects, and data lines are arranged in the areas between adjacent rectangular blocks.

[0117] In the display substrate 80 provided in the above embodiment, the constructed tilted pixels are combined with the lens structure Len to realize the 3D display function of continuous light emission, and the displayed information is more continuous and clearer. At the same time, the purpose of realizing 3D display at multiple angles can be achieved simultaneously.

[0118] In the display substrate 80 provided in the above embodiment, by setting the axial direction of the lens structure Len to be the same as the extension direction of the pixel electrode Pix, or the same as the extension direction of the first data part 101, the lens structure Len and the sub-pixels together form a display unit, which can form a multi-directional 3D display effect and can form a 3D picture in horizontal or vertical screen.

[0119] like Figure 1 As shown, an embodiment of the present invention further provides a display device, including the display substrate 80 provided in the above embodiment, and the display device further includes a color film substrate CF, and the color film substrate CF is arranged opposite to the display substrate 80.

[0120] Exemplarily, the display device further includes a liquid crystal layer, and the liquid crystal layer is located between the display substrate 80 and the color film substrate CF.

[0121] It should be noted that the display device can be any product or component with a display function, such as a television, a monitor, a digital photo frame, a mobile phone, a tablet computer, etc., wherein the display device also includes a flexible circuit board, a printed circuit board and a backplane, etc.

[0122] According to the specific structure of the display substrate 80, in the display substrate 80 provided by the embodiment of the present invention, by setting the pixel electrode Pix to be located in at least two adjacent pixel opening areas 40 at the same time, the pixel electrode Pix can span the area between the adjacent pixel opening areas 40 in the at least two adjacent pixel opening areas 40, and the area between the adjacent pixel opening areas 40 is not covered by the black matrix BM, so that in the at least two adjacent pixel opening areas 40, and in the area between the adjacent pixel opening areas 40 in the at least two adjacent pixel opening areas 40, a control electric field between the pixel electrode Pix and the common electrode can be formed, thereby realizing the continuous display of the at least two adjacent pixel opening areas 40; at the same time, it also solves the problem of displaying rainbow patterns caused by removing the black matrix BM used to cover the area between the adjacent pixel opening areas 40. Therefore, when the display substrate 80 provided by the embodiment of the present invention is applied to a 3D display product, the continuous luminous effect of the 3D display is well achieved.

[0123] In some embodiments, the color film substrate CF includes a black matrix BM, the extension direction of the black matrix BM is the same as the extension direction of the gate line 20 in the display substrate 80, and the orthographic projection of the black matrix BM on the base substrate of the display substrate 80 at least partially overlaps with the orthographic projection of the first touch portion 510 in the display substrate 80 on the base substrate.

[0124] Exemplarily, the display substrate 80 further includes a color filter pattern, and the orthographic projection of at least a portion of the black matrix BM on the display substrate 80 is located between adjacent sub-pixels of different colors.

[0125] The above-mentioned orthographic projection of the black matrix BM on the base substrate of the display substrate 80 at least partially overlaps with the orthographic projection of the first touch portion 510 in the display substrate 80 on the base substrate, so that the black matrix BM can shield the first touch portion 510, thereby avoiding the first touch portion 510 from affecting the display effect of the display substrate 80 and ensuring the display quality of the display substrate 80.

[0126] It should be noted that the signal line extends along the X direction means that the signal line includes a main part and a secondary part connected to the main part, the main part is a line, a line segment or a strip-shaped body, the main part extends along the X direction, and the length of the main part extending along the X direction is greater than the length of the secondary part extending along other directions.

[0127] It should be noted that the "same layer" in the embodiment of the present invention may refer to a film layer on the same structural layer. Or, for example, a film layer on the same layer may be a film layer for forming a specific pattern formed by the same film forming process, and then the film layer is patterned by the same mask through a single composition process to form a layer structure. Depending on the specific pattern, a single composition process may include multiple exposure, development or etching processes, and the specific pattern in the formed layer structure may be continuous or discontinuous. These specific patterns may also be at different heights or have different thicknesses.
