In addition, the three-dimensional dimensions of length, width and height should be included in the actual fabrication.
Fig. 1 is a schematic structural diagram of a display substrate according to an embodiment of the present invention. As shown in fig. 1, the display substrate includes a plurality of sub-pixel group rows, an extending direction of the sub-pixel group rows is a first direction X, a vertical direction of the first direction X is a second direction Y, the plurality of sub-pixel group rows includes a plurality of first sub-pixel group rows 100 and a plurality of second sub-pixel group rows 200, and the first sub-pixel group rows 100 and the second sub-pixel group rows 200 are alternately arranged along the second direction Y. The first subpixel group row 100 includes a plurality of first subpixel groups 110 and a plurality of second subpixel groups 120, the first subpixel groups 110 and the second subpixel groups 120 are alternately arranged, and the second subpixel group row 200 includes a plurality of third subpixel groups 210.
The adjacent first subpixel group row 100 and second subpixel group row 200 are staggered by a width of 0.5 subpixel group, the same subpixel group in the adjacent two first subpixel group rows 100 is staggered by a width of 1 subpixel group, and the subpixel groups at the same position in the adjacent two second subpixel group rows 200 are arranged along the second direction.
The first sub-pixel group 110 includes eight first sub-pixels 111 with the same color, the center points of the eight first sub-pixels 111 are arranged in an octagon shape, the second sub-pixel group 120 includes eight second sub-pixels 121 with the same color, the center points of the eight second sub-pixels 121 are arranged in an octagon shape, the third sub-pixel group 210 includes four third sub-pixels 211 with the same color, and the center points of the four third sub-pixels 211 are arranged in a quadrangle shape. The number of sub-pixels adjacently disposed to the same adjacent sub-pixel group in each sub-pixel group is two, and the first sub-pixel 111, the second sub-pixel 121, and the third sub-pixel 211 are different in color.
Note that the width of the sub-pixel group refers to the length of the sub-pixel group in the first direction X.
It should be noted that the shapes of the first sub-pixel 111 and the second sub-pixel 121 are not limited to the quadrilateral shown in fig. 1, and the shape of the third sub-pixel 211 is not limited to the pentagon shown in fig. 1, and in other embodiments of this embodiment, the shapes of the first sub-pixel 111 and the second sub-pixel 121 may be other than the quadrilateral, and the shape of the third sub-pixel 211 may be other than the pentagon.
For example, fig. 2 is a schematic structural diagram of another display substrate provided in an embodiment of the present invention. As shown in fig. 2, each of the first sub-pixel 111, the second sub-pixel 121, and the third sub-pixel 211 may include a curved edge, a shape formed by eight first sub-pixels 111 in the same first sub-pixel group 110 or eight second sub-pixels 121 in the same second sub-pixel group 120 is an ellipse, and a shape formed by four third sub-pixels 211 in the same third sub-pixel group 210 is also an ellipse.
It is worth noting that in this embodiment, the plurality of sub-pixels in the same sub-pixel group are adjacently and concentratedly disposed, so that the organic light emitting function layers of the plurality of sub-pixels in the same sub-pixel group in the organic light emitting display substrate can correspond to the same evaporation hole or the same organic light emitting material droplet and are formed in the same process step, thereby increasing the number of sub-pixels corresponding to the evaporation hole and the organic light emitting material droplet, improving the resolution of the display substrate, and solving the problem that the pixel density cannot be continuously improved due to the fact that the sizes of the evaporation hole and the organic light emitting material droplet cannot be reduced under the influence of process limits.
It can be understood that the organic light emitting function layer is distributed in the partition area between adjacent sub-pixels in each sub-pixel group, that is, a plurality of sub-pixels in the same sub-pixel group share the same organic light emitting function layer, the functional film layer for really realizing the partition of each sub-pixel is the anode layer, the distribution mode of the anode layer is the same as that of the sub-pixels shown in fig. 1 or fig. 2, and the organic light emitting function layer can emit light under the action of an electric field formed between the anode layer and the cathode layer, so that the organic light emitting function layer in the region where the anode layer is not arranged can not emit light, and the partition of the adjacent sub-pixels is realized.
The display substrate provided by the embodiment includes a plurality of first subpixel group rows 100 and a plurality of second subpixel group rows 200 which are alternately arranged, the first subpixel group row 100 includes a plurality of first subpixel groups 110 and a plurality of second subpixel groups 120 which are alternately arranged, the second subpixel group row 200 includes a plurality of third subpixel groups 210, adjacent first subpixel group rows 100 and second subpixel group rows 200 are staggered by a width of 0.5 subpixel group, the same subpixel groups in two adjacent first subpixel group rows 100 are staggered by a width of 1 subpixel group, the subpixel groups at the same positions in two adjacent second subpixel group rows 200 are arranged along the second direction Y, each of the first subpixel groups 110 and the second subpixel groups 120 includes eight subpixels which have the same color and have octagonal central points, and the third subpixel groups 210 include four subpixels which have the same color and quadrilateral central points. Due to the arrangement, a plurality of sub-pixels in each sub-pixel group can correspond to the same evaporation hole in the mask plate or be formed by using the same organic light-emitting material liquid drop in the printing process, so that the number of the sub-pixels corresponding to the pixel holes in the pixel limiting layer is increased, the pixel density of a display device formed by the display substrate is improved, and the problem that the pixel density cannot be continuously improved due to the fact that the evaporation holes are influenced by the process limit and the size of the organic light-emitting material liquid drop cannot be reduced is solved.
Illustratively, with continued reference to fig. 1, the first subpixel 111 and the second subpixel 121 are both quadrilateral, and the third subpixel 211 is a pentagon.
It should be noted that, in the above-mentioned setting manner, the shape formed by a plurality of sub-pixels in the same sub-pixel group may be a hexagon, and the sides of the hexagon are straight sides, which is convenient for setting the width of the region between the edges of adjacent sub-pixel groups to a certain value, so that the problem of too large local width in the region between adjacent sub-pixel groups does not occur, and the probability of the problem of poor display effect caused by too large distance between adjacent sub-pixels in the local region is reduced.
Alternatively, the colors of the first sub-pixel 111, the second sub-pixel 121, and the third sub-pixel 211 may be any one of red, green, and blue, respectively.
Since red, green, and blue are three primary colors of light, and red, green, and blue with different intensities can be mixed to obtain light of various colors, the colors of the first sub-pixel 111, the second sub-pixel 121, and the third sub-pixel 211 are set to be one of red, green, and blue, respectively, so that the organic light emitting display panel can display various colors, and the display color of the organic light emitting display device can be enriched.
Optionally, with continued reference to fig. 1, the shape and size of each sub-pixel within the same sub-pixel group is the same.
The anode layer is distributed in the same manner as the sub-pixels, and the anode layer corresponding to each sub-pixel has the same shape and size, so that the design and manufacturing difficulty of the anode layer is simplified, and the formed pixel structure is more regular.
Alternatively, the first subpixel 111 and the second subpixel 121 may have the same shape and size, and the area of the third subpixel 211 may be larger than that of the first subpixel 111.
It should be noted that, when the shape and size of the first sub-pixel 111 and the second sub-pixel 121 are the same, the shape and size of the first sub-pixel group 110 and the second sub-pixel group 120 may be the same. In addition, the number of the third sub-pixels 211 in the third sub-pixel group 210 is less than the number of the first sub-pixels 111 in the first sub-pixel group 110 and the number of the second sub-pixels 121 in the second sub-pixel group 120, and therefore, the area of the third sub-pixels 211 is larger than the area of the first sub-pixels 111 and the area of the second sub-pixels 121, so that the shape and the size of the third sub-pixel group 210 can be the same as those of the first sub-pixel group 110 and the second sub-pixel group 120, the shape and the size of each sub-pixel group in the sub-pixel group array are the same, and the sub-pixel group array structure is more regular.
Further, the color of the third sub-pixel 211 may be blue.
It should be noted that, the size of the third sub-pixel 211 is larger than the sizes of the first sub-pixel 111 and the second sub-pixel 121, and the color of the third sub-pixel 211 is set to be blue, so that the size of the blue sub-pixel is larger than the sizes of the red sub-pixel and the green sub-pixel, and because the sensitivity of human eyes to blue is smaller than that of red and green, the above-mentioned setting method can make the recognition degree of human eyes to each sub-pixel in the display picture of the display substrate closer, and improve the visual perception of users.
Fig. 3 is a schematic structural diagram of a display panel according to an embodiment of the present invention. As shown in fig. 3, the display panel 10 includes a display substrate 11 according to any embodiment of the present invention.

Specifically, fig. 4 is a partially enlarged view of fig. 1, and includes a third sub-pixel group, and two first sub-pixel groups and two second sub-pixel groups disposed adjacent to the sub-pixel group. Fig. 4 shows one pixel cell in a dashed box.
FIG. 5 is a schematic diagram of a distribution of a local driving circuit of the display panel of FIG. 1. As shown in fig. 1 and 5, the four pixel units corresponding to the third sub-pixel group 210 form a pixel unit group 300, and the pixel unit group 300 includes a first pixel unit 310, a second pixel unit 320, a third pixel unit 330, and a fourth pixel unit 340, which are sequentially arranged in a clockwise direction. It should be noted that, in order to better show the connection regularity, fig. 5 only illustrates a part of the sub-pixels constituting the complete pixel unit group 300 in fig. 1.
With continued reference to fig. 5, the display panel further includes a plurality of scan lines 410 and a plurality of data lines 420, wherein the first pixel unit 310 and the second pixel unit 320 in the plurality of pixel unit groups corresponding to the same second sub-pixel group row 200 share the same scan line 410, and the third pixel unit 330 and the fourth pixel unit 340 share the same scan line 410. In the pixel unit groups corresponding to the third sub-pixel groups arranged along the second direction Y, the same data line 420 is shared by the sub-pixels with the same color in the first pixel unit 310 and the fourth pixel unit 340, and the same data line 420 is shared by the sub-pixels with the same color in the second pixel unit 320 and the third pixel unit 330.

It should be noted that, in the organic light emitting display panel, the pixel driving circuit includes a plurality of transistors, so that the connection relationship is clearer, the plurality of transistors are simplified into one, and corresponding connection lines, including an emit line, a PVDD line, a PVEE line, etc., are omitted, where the emit line may be parallel to the scan line 410, and the number of the emit lines is the same as that of the scan line 410.
It is noted that the scan line 410 shared by the plurality of pixel units means that all the sub-pixels in the plurality of pixel units are connected to the same scan line 410.
It should be noted that, with such an arrangement, the connection between each sub-pixel and the scan line 410 and the data line 420 has regularity, the connection relationship is clear, and the phenomenon of misconnection is not likely to occur, and the sub-pixels are closer to the corresponding scan line 410 and data line 420, so that the occupation ratio of the connection lines to the internal space of the display substrate is reduced.
FIG. 6 is a schematic diagram of another distribution of local driving circuits of the display panel of FIG. 1.
