[0033] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0035] Before describing in detail the display substrate and the display device provided by the embodiments of the present disclosure, it is necessary to describe the related technologies as follows:

[0036] In the related art, for narrow-frame display products, taking a spliced ​​screen as an example, Figure 1 The figure shows the cross-sectional structure diagram of the splicing screen product structure. Figure 2 for Figure 1 A schematic diagram of the shielding of some pixels around the spliced ​​screen by the frame in the top view, with only one corner of the spliced ​​screen shown in the figure. Figure 1 and Figure 2 As shown, the frame 20 will block some pixels around the display substrate 10. Due to the difference in straightness of the frame edge, the degree of blocking will be different, and the degree of opening loss of the RGB sub-pixels 30 in different pixel units will be different, which will cause rainbow lines to appear on the edge of the screen, and the colors presented on the two opposite sides will also be different.

[0037] In order to improve the problem of rainbow patterns in the above-mentioned display products, the embodiments of the present disclosure provide a display substrate and a display device. By improving the pixel arrangement structure, the phenomenon of rainbow patterns in display products can be improved to enhance product quality.

[0038] Figure 3 FIG. 1 is a schematic diagram of a pixel arrangement structure in a display substrate provided by an embodiment of the present disclosure. Figure 3As shown, the display substrate provided by the embodiment of the present disclosure includes a middle display area A, and a first peripheral display area B1 and a second peripheral display area B2 located on opposite sides of the middle display area A. The display area includes a pixel unit array, and the pixel unit array includes a plurality of pixel units 300 distributed in an array. Each pixel unit 300 includes at least two sub-pixels emitting light of different colors. The opening shape of the sub-pixel is a rectangle, and the rectangle includes a long side 300b and a short side 300a.

[0039] In at least one of the first peripheral display area B1 and the second peripheral display area B2, and the intermediate display area A, the sub-pixels in each pixel unit 300 are arranged in sequence along the short side extension direction of the sub-pixels; and the extension direction of the first peripheral display area B1 and the second peripheral display area B2 is perpendicular to the short side extension direction of the sub-pixels in the intermediate display area A, and the short side extension direction of the sub-pixels in at least one of the first peripheral display area B1 and the second peripheral display area B2 is perpendicular to the short side extension direction of the sub-pixels in the intermediate display area A.

[0040] by Figure 3 Taking the drawing direction shown in as an example, the short side extension direction of each sub-pixel in the middle display area A is the row direction X of the pixel unit array, and the long side extension direction is the column direction Y of the pixel unit array. The first peripheral display area B1 is the peripheral display area located on the left side of the middle display area A; the second peripheral display area B2 is the peripheral display area located on the right side of the middle display area A, and each sub-pixel in the pixel unit 300 in the middle display area A is arranged in sequence along the short side extension direction, that is, arranged in sequence along the X direction; the short side extension direction of each sub-pixel of the pixel unit 300 in the first peripheral display area B1 and the second peripheral display area B2 is perpendicular to the short side extension direction of the sub-pixel in the middle display area, that is, it is arranged along the Y direction, and each sub-pixel in the pixel unit is arranged in sequence along the short side extension direction, that is, arranged in sequence along the Y direction.

[0041] When the display substrate provided by the embodiment of the present disclosure is applied to a narrow-frame display product, especially to a spliced ​​screen, the first peripheral display area B1 and the second peripheral display area B2 will be partially blocked by the corresponding four side frames on the frame.

[0042] By adopting the above scheme, by improving the pixel arrangement structure on the display substrate, the sub-pixels of the pixel unit 300 in the middle display area A located in the middle position of the display area are arranged in sequence along the extension direction of the short side, and the sub-pixels of the pixel unit 300 in at least one area of ​​the two peripheral display areas (i.e., the first peripheral display area B1 and the second peripheral display area B2) located in the peripheral position and perpendicular to the extension direction of the short side of the sub-pixels in the middle display area are designed to be arranged in sequence along the extension direction of the short side, and the short sides of the sub-pixels in at least one area of ​​the first peripheral display area B1 and the second peripheral display area B2 are arranged perpendicular to the short sides of the sub-pixels in the middle display area A. In this way, when the display substrate is applied to a narrow frame structure, the edge extension direction of the frame located on the first side 110 and the second side 120 will be consistent with the sub-pixel arrangement direction in each pixel unit 300 in the first peripheral display area B1 and the second peripheral display area B2. Therefore, when the frame blocks the pixel unit 300 of the first peripheral display area B1 and / or the second peripheral display area B2, a part of the pixel unit 300 of the first peripheral display area B1 and the second peripheral display area B2 is blocked by the frame, while the other part is not blocked by the frame. The sub-pixel openings in each blocked pixel unit 300 in the peripheral display area will be lost in the same proportion, thereby improving the problem of rainbow patterns and improving product quality.

[0043] It should be noted that if Figure 3 As shown, the first peripheral display area B1 may include only one column of pixel units 300 or at least two columns of pixel units 300; similarly, the second peripheral display area B2 may include only one column of pixel units 300 or at least two columns of pixel units 300.

[0044] In some embodiments, as shown in the figure, the pixel unit 300 includes at least a first sub-pixel 310, a second sub-pixel 320 and a third sub-pixel 330. For example, the first sub-pixel 310 is a red sub-pixel, the second sub-pixel 320 is a green sub-pixel, and the third sub-pixel 330 is a blue sub-pixel.

[0045] like Figure 3 As shown, the pixel opening area of ​​the first sub-pixel 310 in the middle display area A is the same as that of the first sub-pixel 310 in the first peripheral display area B1 and the second peripheral display area B2; the pixel opening area of ​​the second sub-pixel 320 in the middle display area A is the same as that of the second sub-pixel 320 in the first peripheral display area B1 and the second peripheral display area B2; the pixel opening area of ​​the third sub-pixel 330 in the middle display area A is the same as that of the third sub-pixel 330 in the first peripheral display area B1 and the second peripheral display area B2.

[0046] In the above solution, for sub-pixels of the same color, the sub-pixel opening area in the first peripheral display area B1 and the second peripheral display area B2 is the same as the sub-pixel opening area in the middle display area A.

[0047] In order to realize the pixel arrangement structure in the display substrate provided by the embodiment of the present disclosure, there may be multiple corresponding display driving circuit wiring modes in the display substrate in the embodiment of the present disclosure.

[0048] In the display substrate provided by the embodiment of the present disclosure, the base substrate 100 is provided with a data line 500 and a gate line 600 that are crossed and insulated, and a thin film transistor and a pixel electrode are provided in each sub-pixel, and the gate of the thin film transistor is connected to the gate line 600, the source is connected to the data line 500, and the drain is connected to the pixel electrode. Among them, in the multiple pixel units 300 in the same row, the sources of the thin film transistors of the sub-pixels of different color lights are respectively connected to different data lines 500; and in the multiple pixel units 300 in the same row, the gates of the thin film transistors of each sub-pixel are connected to the same gate line 600 adjacent to the pixel unit 300 in the row, or to at least two gate lines 600 adjacent to the pixel unit 300 in the row, and the gates of the thin film transistors of the sub-pixels of the same color are connected to the same gate line 600.

[0049] Since the arrangement direction of each sub-pixel of the pixel unit 300 in the first peripheral display area B1 and the second peripheral display area B2 is different from the arrangement direction of each sub-pixel of the pixel unit 300 in the middle display area A, for the pixel units 300 in the same row, the signal line wiring method in the first peripheral display area B1 and the second peripheral display area B2 will be different from the signal line wiring method in the middle display area A.

[0050] In the middle display area A, since the sub-pixels of each pixel unit 300 are sequentially arranged along the direction in which the short sides of the sub-pixels extend, that is, the X direction, and the gate line 600 extends along the X direction, the thin film transistors in each sub-pixel are at the same distance from the gate line 600, and the source of the thin film transistor can be directly connected to the gate line 600; and in the pixel units 300 in the first peripheral display area B1 and the second peripheral display area B2, since the sub-pixels are sequentially arranged along the direction perpendicular to the short sides of the sub-pixels in the middle display area, that is, the Y direction, the distances from each sub-pixel in the same pixel unit 300 to the gate line 600 are different. In order to make each sub-pixel in the same pixel unit 300 All sub-pixels are connected to the same or at least two gate lines 600 adjacent to the pixel unit 300. In at least one of the first peripheral display area B1 and the second peripheral display area B2, at least one gate line branch 600' is provided on the gate line 600. The gate line branch 600' is cross-connected with the gate line 600. The extension direction of the gate line branch 600' is the extension direction of the long side of the sub-pixel in the middle display area, that is, the Y direction, and can be extended from the gate line 600. The source of the thin film transistor of at least one color sub-pixel in the pixel unit 300 is connected to the gate line 600 through the gate line branch 600'.

[0051] As an exemplary embodiment, Figure 4 As shown, when the gates of the sub-pixels in the same row of the pixel units 300 are connected to the same gate line 600 adjacent to the row of pixel units 300, in the first peripheral display area B1 and the second peripheral display area B2, at least one gate line branch 600' is further provided on the gate line 600, and the gate line branch 600' is cross-connected with the gate line 600, and the gate of the thin film transistor of a sub-pixel in the pixel unit 300 closest to the gate line 600 is connected to the gate line 600, and the gate of the thin film transistor of the sub-pixel on the side of the pixel unit 300 away from the gate line 600 is connected to the gate line branch 600'.

[0052] For example, Figure 4Taking the display substrate shown as an example, the pixel unit 300 includes a first sub-pixel 310, a second sub-pixel 320 and a third sub-pixel 330, and the thin film transistors of the same row of pixel units 300 are all connected to the same gate line 600 located on the side of the pixel unit 300 of the row close to the fourth side 140 (that is, the same gate line 600 located below the pixel unit 300 shown in the figure). In the first peripheral display area B1 and the second peripheral display area B2, the first sub-pixel 310 of the pixel unit 300 is located on the side closest to the fourth side 140, and the third sub-pixel 330 is located on the side closest to the third side 130. Two gate line branches 600' are provided on the gate line 600. The thin film transistor in the first sub-pixel 310 is directly connected to the gate line 600, the thin film transistor of the second sub-pixel 320 is connected to the gate line 600 through one of the two gate line branches 600', and the thin film transistor of the third sub-pixel 330 is connected to the gate line 600 through the other gate line branch 600' of the two gate line branches 600'.

[0053] As another exemplary embodiment, Figure 5 As shown, when the gates of the sub-pixels in the same row of the pixel units 300 are connected to at least two gate lines 600 adjacent to the row of pixel units 300, in the first peripheral display area B1 and the second peripheral display area B2, one of the at least two gate lines 600 adjacent to the row of pixel units 300 is a first gate line 610, and the other gate line 600 is a second gate line 620;

[0054] At least one first gate line branch 610' is disposed on the first gate line 610, and the first gate line branch 610' is cross-connected with the first gate line 610, or at least one second gate line branch 620' is disposed on the second gate line 620, and the second gate line branch 620' is cross-connected with the second gate line 620;

[0055] The gate of the thin film transistor of a sub-pixel in the pixel unit 300 closest to the first gate line 610 is connected to the first gate line 610, the gate of the thin film transistor of a sub-pixel in the pixel unit 300 closest to the second gate line 620 is connected to the second gate line 620, and the gate of the thin film transistor of the sub-pixel in the pixel unit 300 far from the first gate line 610 and the second gate line 620 is connected to the first gate line branch 610' or the second gate line branch 620'.

[0056] For example, Figure 5Taking the display substrate shown in the figure as an example, the pixel unit 300 includes a first sub-pixel 310, a second sub-pixel 320 and a third sub-pixel 330, and the thin film transistors of the pixel units 300 in the same row are all connected to the first gate line 610 and the second gate line 620 adjacent to the pixel units 300 in the same row (that is, the two gate lines 600 located above and below the pixel unit 300 shown in the figure). In the first peripheral display area B1 and the second peripheral display area B2, the first sub-pixel 310 of the pixel unit 300 is located on the side closest to the fourth side 140, and the third sub-pixel 330 is located on the side closest to the third side 130, wherein the first sub-pixel 310 can be directly connected to the first gate line 610 or connected to the first gate line 610 through the first gate line branch 610', the third sub-pixel 330 can be directly connected to the second gate line 620 or connected to the second gate line 620 through the second gate line branch 620', and the second sub-pixel 320 can be connected to another first gate line branch 610' on the first gate line 610 or another second gate line branch 620' on the second gate line 620.

[0057] In addition, as an exemplary embodiment, Figure 4 As shown, in the middle display area A, sub-pixels of different colors are respectively connected to different data lines 500 , and sub-pixels of the same color in the same column of pixel units 300 are connected to the same data line 500 .

[0058] In the first peripheral display area B1 and the second peripheral display area B2, sub-pixels of the same color in the same column of the pixel units 300 are connected to the same data line 500, and each data line 500 is arranged to cross the gate line 600 vertically or to be arranged in a winding manner to bypass the sub-pixels.

[0059] by Figure 4 As shown in the figure, in the first peripheral display area B1 and the second peripheral display area B2, sub-pixels of different colors in the same pixel unit 300 are connected to different data lines 500, and the data lines 500 are perpendicular to the gate lines 600. The specific wiring method of the data lines 500 should ensure that different data lines 500 do not overlap.

[0060] As a specific embodiment, for example Figure 6As shown, in the first peripheral display area B1 and the second peripheral display area B2, the first data line 500 connected to the first sub-pixel 310 in the pixel unit 300 and the third data line 500 connected to the third sub-pixel 330 are respectively located on opposite sides of the pixel unit 300, namely, the side close to the middle display area A and the side away from the middle display area A, the second data line 500 connected to the second sub-pixel 320 is located in the middle of the pixel unit 300, and the pixel electrode of each sub-pixel is divided into a first part 300A and a second part 300B, the first part 300A and the second part 300B are connected by a connecting bridge 300C, and the orthographic projections of the first part and the second part on the substrate 100 do not overlap with the orthographic projection of the second data line 500 on the substrate 100, so as to reduce parasitic capacitance, etc.
