[0048] Embodiments of the present disclosure provide a display substrate and a display device. Combined with the accompanying drawings, the display substrate and the display device in the embodiments of the present disclosure are described in detail below. Without conflict, the features in the embodiments described at below may complement or combine with each other.
[0049] The embodiments of the present disclosure provide a display substrate. As shown in FIG. 1, the display substrate includes a substrate 10 and a plurality of sub-pixels 20 disposed on the substrate 10. The plurality of sub-pixels 20 are arranged in a plurality of rows and columns, each of the sub-pixels 20 has a first size dl in a row direction X and a second size d2 in a column direction Y, the first size dl being greater than the second size d2.
[0050] As shown in FIGS. 2 to 4, the the sub-pixel includes a first electrode 21 and a second electrode 22 disposed opposite to each other. Each of the sub-pixels 20 also includes liquid crystal molecules disposed between the first electrode 21 and the second electrode 22. The display substrate also includes a plurality of power signal lines 30, the power signal lines 30 extending along the column direction Y. Two first electrodes 21 adjacent in the row direction X are connected through the power signal line 30, and two first electrodes 21 adjacent in the column direction Y are connected through the power signal line 30. The extension of the power signal line 30 along the column direction Y means that the power signal line 30 as a whole extends along the column direction Y, and the power signal line 30 may include a portion extending along the row direction X.
[0051] In the display substrate provided in the embodiments of the present disclosure, the power signal lines extend in the column direction, which can avoid the problem of segment differences existing in different regions of the power signal line when the power signal line extends along the row direction and a portion of the power signal line overlaps with the first electrode in the stacking direction of the film layer, and in turn leads to poor anchoring of liquid crystal molecules in the region where there are segment differences in the power signal line and causes light leakage. That is, extending the power signal line in the column direction can solve this problem. Therefore, the opening for defining the light-emitting region of the sub-pixel opened in the light-shielding layer on the side of the sub-pixel away from the substrate can be arranged larger to improve the pixel aperture ratio of the display substrate, and thus improve the light efficiency of the display substrate.
[0052] In one embodiment, the display substrate also includes a plurality of pixel driving circuits. The pixel driving circuits of the display substrate may be in one-to-one correspondence with the sub-pixels, and each of the pixel driving circuits is used to drive the corresponding sub-pixel.
[0053] In one embodiment, as shown in FIG. 1, the display substrate also includes a plurality of scanning signal lines Gate extending along the row direction X and a plurality of data signal lines Data extending along the column direction. The sub-pixels in the same row are connected to the same scanning signal line Gate, and the scanning signal line Gate may be disposed between two adjacent rows of sub-pixels. The number of data signal lines Data may be the same as the number of rows of sub-pixels, and the data signal lines Data may be disposed between two adjacent columns of sub-pixels. As the size of the sub-pixel 20 in the row direction X is larger than the size of the sub-pixel 20 in the column direction Y, the display substrate may reduce the number of columns of sub-pixels in the display substrate when the size of the subpixel 20 in the row direction X is certain, which may reduce the number of the data signal lines Data, which may reduce the number of the driver chips used to provide signals to the data signal lines Data, and reduce the cost of the display substrate.
[0054] In one embodiment, as shown in FIGS. 1 to 3, the data signal lines Data are provided on opposite sides of the same column of sub-pixels. Pixel driving circuits corresponding to two sub-pixels 20 adjacent in the column direction Y are provided, with one of the pixel driving circuits being connected to one of the data signal lines Data adjacent thereto, and the other of the pixel driving circuits being connected to another of the data signal lines Data adjacent thereto. That is, the pixel driving circuits corresponding to the two sub-pixels 20 adjacent in the column direction Y are connected to different data signal lines Data. In order to avoid polarization of the liquid crystal molecules, when the display substrate displays, a signal of one of the two adjacent data signal lines Data is larger than a signal of the power supply signal line 30, and a signal of the other data signal line Data is smaller than the signal of the power supply signal 30. The above setting may cause one of the two pixel driving circuits adjacent in the column direction to receive a data signal that is larger than the signal of the power supply signal line 30, and the other pixel driving circuit to receive a data signal that is smaller than the signal of the power supply signal line 30, and may cause one of the two pixel driving circuits adjacent in the row direction to receive a data signal that is larger than the signal of the power supply signal line 30, and the other pixel driving circuit to receive a signal that is smaller than the signal of the power supply signal line 30, which helps to improve the display uniformity of the display substrate and improve the display effect of the display substrate.
[0055] In one embodiment, the plurality of sub-pixels in the display substrate are divided into a plurality of pixel units, and each pixel unit may include a plurality of sub-pixels with different light-emitting colors. The plurality of sub-pixels in the same pixel unit may be arranged along the column direction Y. Each sub-pixel of the same pixel unit is connected to a different scanning signal line Gate. The light-emitting color of a plurality of sub-pixels disposed in the same row may be the same.

In this way, the power signal line 30 is in a zigzag shape, and two driver transistors 70 adjacent in the column direction can be arranged on opposite sides of the power signal line 30, such that two adjacent driver transistors 70 are arranged on opposite sides of the data signal line Data, and thus the display uniformity of the display substrate is improved.
[0076] In one embodiment, as shown in FIG. 3, the first sub-signal line 31 includes a fourth segment 314 and a fifth segment 315 that are connected. The fourth segment 314 extends along the row direction X, the fifth segment 315 extends along the column direction Y, and an end portion of the fourth segment 314 distal from the fifth segment 315 and an end portion of the fifth segment 315 distal from the fourth segment 314 are connected to the second sub-signal line 32. In this way, it is convenient for the first sub-signal line 31 to be connected to the second sub-signal line 32, and it is convenient for the first sub-signal line 31 to be connected to the two first electrodes 21 adjacent in the row direction X. At the same time, it is possible to make the power signal line 30 in a zigzag shape, and it is convenient for the two driver transistors 70 adjacent in the column direction to be arranged on opposite sides of the power signal line 30, and it is possible to make the two adjacent driver transistors 70 to be arranged on the opposite sides of the data signal line Data, such that the display uniformity of the display substrate is improved.
[0077] In one embodiment, as shown in FIG. 3, for two second electrodes 22 connected to the same the power signal line 30 and adjacent in the row direction X, a distance from one of the two second electrodes 22 to the fifth segment 315 is different from a distance from the other of the two second electrodes 22 to the fifth segment 315 in the row direction X.
[0078] In one embodiment, as shown in FIG. 3, for two sub-pixels connected to the same the power signal line 30 and adjacent in the column direction Y, a distance from one of the two second electrodes 22 to the fifth segment 315 is different from a distance from the other of the two second electrodes 22 to the fifth segment 315 in the row direction X. In this way, it is more conducive to the power signal line 30 being in a zigzag shape.
[0079] In one embodiment, as shown in FIG. 4, the first sub-signal line 31 includes a sixth segment 316 and a seventh segment 317 that are connected. The sixth segment 316 extends along the row direction X and is disposed on a side of the seventh segment 317, and the seventh segment 317 extends along the column direction Y; and opposite ends of the seventh segment 317 are connected to the second sub-signal line 32 respectively. In this way, the sixth segment 316 and the seventh segment 317 are connected to two adjacent first electrodes 21 that are different in the row direction, which is convenient for the first sub-signal line 31 to be connected to the two first electrodes 21 adjacent in the row direction X, and for the first sub-signal line 31 to be connected to the second sub-signal line 32.
[0080] In one embodiment, as shown in FIG. 4, for two second electrodes 22 connected to the same the power signal line 30 and adjacent in the row direction X, a distance from one of the two second electrodes 22 to the seventh segment 317 is different from a distance from another of the two second electrodes 22 to the seventh segment 317 in the row direction X.
[0081] In one embodiment, as shown in FIGS. 5 to 7, the first sub-signal line 31 is disposed in the first metal conductive layer 91, and the second sub-signal line 32 is disposed in the second metal conductive layer 92. That is, the first sub-signal line 31 is disposed in the same layer as the gate electrode 71, and the second sub-signal line 32 is disposed in the same layer as the first electrode 72 and the second electrode 73. In this way, in the same power supply signal line 30, the second sub-signal line 32 can connect two adjacent first sub-signal lines 31 together while avoiding a short circuit between the second sub-signal line 32 and the scanning signal line Gate. In addition, the material of the first sub-signal line 31 and the material of the second sub-signal line 32 are both metal, which can make the resistance of the power supply signal line 30 smaller, which is conducive to improving the consistency of the level magnitude of each first electrode 21.
[0082] In one embodiment, as shown in FIG. 6 and FIG. 7, the insulating layer disposed between the first metal conductive layer 91 and the second metal conductive layer 92 is provided with a plurality of via holes 81, and the first sub-signal line 31 is connected to the second sub-signal line 32 through the via holes 81. Specifically, one end of the second subsignal line 32 is connected to the first sub-signal line 31 through one via hole 81 and the other end of the second sub-signal line 32 is connected to the first sub-signal line 31 through one via hole 81.
[0083] In one embodiment, as shown in FIG. 7, an orthographic projection of the via hole 81 on the substrate falls in an edge region of the orthographic projection of the second electrode 22 on the substrate and fals within an orthographic projection of the light-shading layer on the substrate. The via hole 81 is provided in the edge region of the second electrode 22 and covered by the light-shading layer, which can reduce the influence on the aperture ratio of the sub-pixels.
[0084] In one embodiment, as shown in FIG. 7, an orthographic projection of the via hole 82 in the insulating material layer on the substrate falls in the edge region of the orthographic projection of the second electrode 22 on the substrate and is located within the orthographic projection of the light-shielding layer on the substrate. The via hole 82 is provided in the edge region of the second electrode 22 and covered by the light-shielding layer, which can avoid the via hole 82 from affecting the display effect of the display substrate.
[0085] In one embodiment, as shown in FIGS. 5 to 7, when forming the array substrate of the display substrate, the first metal conductive layer 91 is first formed; an insulating layer disposed on a side of the first metal conductive layer 91 distal from the substrate is subsequently formed; the second metal conductive layer 92 is subsequently formed on the insulating layer, and the second sub-signal line 32 disposed in the second metal conductive layer 92 is connected to the first sub-signal line 31 disposed in the first metal conductive layer 91 through the via hole 81 provided in the insulating layer; and the first electrode 21 is subsequently formed, and the first electrode 21 overlaps with the second sub-signal line 32. The array substrate and the color filter substrate are cell bonded, as as to obtain the display substrate shown in FIG. 2.
[0086] If the first electrode is formed before the first metal conductive layer is formed when the display substrate is formed, in order to avoid short circuit between the first electrode and the scanning signal line Gate in the first metal conductive layer, it is necessary to set the distance between the first electrode and the scanning signal line Gate in the column direction to be greater than or equal to 7 pm. In this embodiment, as an insulating layer is provided between the first electrode 21 and the scanning signal line Gate located in the first metal conductive layer 91, there is no risk of short circuit between the first electrode 21 and the scanning signal line Gate. The distance between the first electrode 21 and the scanning signal line Gate in the column direction can be set to be relatively small, thereby increasing the area of the opening of the light-shielding layer and effectively improving the aperture ratio of the sub-pixels.
[0087] In one embodiment, the power signal line includes a segment (also known as a second segment 312) disposed between two openings 50 adjacent in the row direction X and extending along the column direction Y. As shown in FIG. 8, the minimum distance between an edge of an orthographic projection of the second segment 312 on the substrate 10 and an edge of an orthographic projection of an adjacent opening 50 on the substrate 10 is xl , with xl ranging from 4 pm~ 8 um. In this way, the problem of reflection caused by the exposure of the second segment 312 due to alignment deviation when the array substrate and the color filter substrate are cell bonded can be avoided when xl is too small. Also, the problem of affecting the aperture ratio of the sub-pixels when xl is too large can be avoided. In some embodiments, xl may be 4 pm, 4.5 um, 5 pm, 5.5 um, 6 um, 6.5 pm, 7 pm, 7.5 pm, 8 pm, and the like.
[0088] In one embodiment, as shown in FIG. 8, an orthographic projection of one first electrode 21 on the substrate 10 overlaps with the orthographic projection of the second segment 312 on the substrate 10, and an edge of the orthographic projection of the second segment on the substrate 10 is located inside an edge of the orthographic projection of the first electrode 21 on the substrate 10, and the minimum distance between the edge of the orthographic projection of the first electrode 21 on the substrate 10 and the edge of the orthographic projection of the second segment 312 on the substrate 10 is x2, with x2 ranging from 1.5 pm~ 3 pm. In this way, even if there is an alignment deviation between the first electrode 21 and the first sub-signal line 31, it can be ensured that there is an overlapping region between the first electrode and the second segment in the stacking direction of the film layer, so as to facilitate the first electrode being connected to the first sub-signal line. In some embodiments, x2 may be 1.5 pm, 2.0 pm, 2.5 pm, 3.0 pm, and the like.
[0089] In one embodiment, as shown in FIG. 9, in the column direction, a distance between an edge of an orthographic projection of the first signal line 41 on the substrate 10 and an edge of an orthographic projection of an adjacent opening 50 on the substrate 10 is x3, with x3 ranging from 6 pm~ 11 pm. In this way, it can avoid the problem of side view light leakage on the display substrate caused by too small the range of x3, and also avoid affecting the aperture ratio of the sub-pixels due to too large the range of x3. In some embodiments, x3 may be 6 pm, 7 pm, 8 pm, 9 pm, 10 pm, 11 pm, and the like.
[0090] In one embodiment, as shown in FIG. 9, in the column direction, a distance between the edge of the orthographic projection of the first signal line 41 on the substrate 10 and the edge of the orthographic projection of the first electrode 21 on the substrate 10 is x4, with x4 ranging from 3 pm~ 5 pm. In this way, it is possible to ensure that the signal of the first signal line 41 does not interfere with the signal of the first electrode 21 while reduce the effect on the aperture ratio of the sub-pixels. In some embodiments, x4 may be 3 pm, 3.5 pm, 4 pm, 4.5 pm, 5 pm, and the like.
[0091] It should be noted that the above range of values is determined when the liquid crystal molecules in the display substrate are positive liquid crystal molecules.
[0092] In another embodiment, when the liquid crystal molecules are negative liquid crystal molecules, as shown in FIG. 10, in the column direction, a distance between the edge of the orthographic projection of the first signal line 41 on the substrate 10 and the edge of the orthographic projection of the adjacent opening 50 on the substrate 10 is x5, with x5 ranging from 3 pm~ 5 pm. When the liquid crystal molecules are negative liquid crystal molecules, there is no problem of light leakage in the row direction of the liquid crystal molecules. Therefore, x5 can be set to a smaller value..
[0093] Further, as shown in FIG. 10, the edge of the orthographic projection of the opening 50 of the light-shading layer 51 on the substrate 10 extending along the column direction Y is located outside an orthographic projection of the corresponding first electrode 21 on the substrate 10. That is, when the liquid crystal molecules are negative liquid crystal molecules, most of the region where the opening 50 increases is a non-light-emitting region, but due to the alignment deviation when the color filter substrate and the array substrate are cell bonded, it can be avoided that the light-shading layer 51 covers the effective light-emitting region of the sub-pixel after being cell bonded, which helps to improve the aperture ratio of the sub-pixels.
[0094] In one embodiment, as shown in FIGS. 11 to 13, when forming the array substrate of the display substrate, the first electrode 21 is first formed; the first metal conductive layer 91 is subsequently formed, and the first sub-signal line 31 disposed in the first metal conductive layer overlaps with the first electrode 21; an insulating layer disposed on a side of the first metal conductive layer 91 distal from the substrate is subsequently formed; the second metal conductive layer 92 is subsequently formed on the insulating layer, and the second sub-signal line 32 disposed in the second metal conductive layer 92 is connected to the first sub-signal line 31 disposed in the first metal conductive layer 91 through the via hole 81 provided in the insulating layer. The array substrate and the color filter substrate are cell bonded to form the display substrate shown in FIG. 3.
[0095] Further, as shown in FIG. 14, in the column direction, a distance between the edge of the orthographic projection of the first signal line 41 on the substrate 10 and the edge of the orthographic projection of the first electrode 21 on the substrate 10 is x6, with x6 ranging from 5 pm~ 7 pm. In this way, it can be avoided that the conductive material falls into the gap between the first signal line 41 and the first electrode 21 during the formation of the first signal line 41 and the first electrode 21, resulting in short circuit between the first signal line 41 and the first electrode 21. In some embodiments, x6 may be 5 pm, 5.5 pm, 6 pm, 6.5 pm, 7 pm, and the like.
[0096] In another embodiment, as shown in FIG. 15 and FIG. 16, the power signal line 30 includes a first portion 33 extending along the column direction Y and a second portion 34 extending along the row direction X. The first portion 33 is disposed in the second metal conductive layer 92, the second portion 34 is disposed in the first metal conductive layer 91 or in the same layer as the first electrodes 21, and two adjacent first electrodes 21 disposed in a same row are connected through the second portion 34. The second portion 34 is disposed between the second metal conductive layer 92 and the substrate. The display substrate also includes an insulating layer disposed between the second portion 34 and the second metal conductive layer 92. The insulating layer is provided with a via hole 83, and the first portion 33 is connected to the second portion 34 through the via hole 83. In the embodiment shown in FIG. 15, the second portion 34 is disposed in the first metal conductive layer 91, and the first electrode 21 may overlap with the second portion 34. In the embodiment shown in FIG. 16, the second portion 34 is provided in the same layer as the first electrode 21 and is formed simultaneously in the same process. In this way, the portion of the power signal line 30 extending along the column direction Y is integrally formed in the same layer, compared with the embodiment in which different regions of the portion of the power signal line extending along the column direction Y are located in different layers and are connected through via holes, it helps to reduce the resistance of the power signal line 30 and improve the consistency of the level signal of the first electrode 21.
[0097] In one embodiment, as shown in FIGS. 2 to 4, FIG. 15 and FIG. 16, the display substrate also includes a plurality of spacers 62. The spacers 62 can keep a fixed distance between the color film substrate and the array substrate.
[0098] In one embodiment, as shown in FIG. 2, FIG. 4, FIG. 15, and FIG. 16, the display substrate also includes a plurality of supporting portions 61, with an orthographic projection of one spacer 62 on the substrate falling within an orthographic projection of one supporting portion 61 on the substrate.

[0100] In another embodiment, as shown in FIG. 3, the spacer 62 is disposed on a side of the power signal line 30 distal from the substrate, and an orthographic projection of the spacer 62 on the substrate overlaps with an orthographic projection of the power signal line 30 on the substrate. In the embodiment shown in FIG. 3, a portion of the orthographic projection of the spacer 62 on the substrate 10 overlaps with the orthographic projection of the power signal line 30 on the substrate, and a portion of the orthographic projection of the spacer 62 on the substrate 10 overlaps with the orthographic projection of the data signal line Data on the substrate. In this way, the supporting portion for supporting the spacer 62 may may not be provided, which helps to reduce the distance between two adjacent columns of sub-pixels.

In another embodiment, as shown in FIG. 4, FIG. 14, and FIG. 15, the orthographic projections of two drive transistors 70 adjacent in the column direction Y on the substrate are located on the same side as the orthographic projection of the adjacent power signal lines 30 on the substrate. The power supply signal line 30 adjacent to the drive transistor 70 refers to the power supply signal line 30 with the smallest distance from the drive transistor 70 in the row direction X.
[0103] In one embodiment, as shown in FIG. 2, FIG. 3, and FIG. 16, the orthographic projections of two driver transistors 70 adjacent in the column direction Y on the substrate are located on opposite sides of the orthographic projection of an adjacent data signal line Data on the substrate.
