[0002] With the continuous development and application of display technology, users have higher and higher requirements on the display effects of electronic display products.

However, for narrow-border products with left and right borders less than 1 mm and high resolution, a large number of signal lines need to be set without measuring the borders. The 1 mm borders on the left and right cannot meet the space for single-layer wiring or double-layer alternating wiring. Summary of the invention

[0098] 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. And in the absence of conflict, the embodiments in the present disclosure and the features in the embodiments can be combined with each other. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present disclosure.

[0099] Unless otherwise defined, the technical terms or scientific terms used in the present disclosure should be understood by people with ordinary skills in the field to which the present disclosure belongs. "First", "second" and similar words used in the present disclosure do not indicate any order, quantity or importance, but are only used to distinguish different components. "Include" or "comprise" and similar words mean that the elements or objects appearing before the word cover the elements or objects listed after the word and their equivalents, without excluding other elements or objects. "Connect" or "connected" and similar words are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect.

[0100] It should be noted that the sizes and shapes of the figures in the accompanying drawings do not reflect the actual proportions, and are only intended to illustrate the present disclosure. The same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions.

[0101] In the related art, for low-resolution display products, the signal lines in the peripheral areas on the left and right sides of the display area are arranged in a single-layer wiring or double-layer alternating wiring manner. However, for narrow-border products with left and right frames less than 1 mm and high resolution, a large number of signal lines need to be arranged in each frame, and the left and right 1 mm frames cannot provide sufficient wiring space for single-layer wiring or double-layer alternating wiring. If the multiple signal lines on one side of the display area are arranged in a double-layer overlapping wiring manner, that is, the orthographic projections of the signal lines on different layers have overlapping areas, a parallel plate capacitor will be formed between the two layers of signal lines. According to the capacitance calculation formula C=εS / d, where ε is the dielectric constant of the medium between the two layers of signal lines, S is the overlapping area of ​​the two layers of signal lines, and d is the distance between the two layers of signal lines, it can be seen that the use of overlapping wiring will make the capacitance of the overlapping area of ​​the orthographic projection of the signal lines become twice the capacitance of the single-layer wiring, affecting the charging rate of the pixel.

[0102] The present disclosure provides a display substrate, such as Figure 1 As shown, the display substrate includes:

[0103] The first base substrate 1 comprises a display area 101 and a peripheral area 102 surrounding the display area 101 ; the peripheral area 102 comprises: first peripheral areas 1021 respectively located on both sides of the display area 101 in the first direction X;

[0104] At least one signal line group 2 is located at least in the first peripheral area 1021 on one side of the first substrate 1, and includes a plurality of signal lines 201; the plurality of signal lines 201 include: a plurality of first signal lines 2011 arranged along a first direction X, and a plurality of second signal lines 2012 located in a different layer from the plurality of first signal lines 2011 and arranged along the first direction X; in the first peripheral area 1021, the signal line group 2 includes a first area 3 and a second area 4 arranged in the extension direction thereof; the number of signal lines included in the first area 3 is greater than the number of signal lines included in the second area 4; in the first area 3, the plurality of first signal lines 2011 The orthographic projection of the first substrate 1 overlaps with the orthographic projection of the plurality of second signal lines 2012 on the first substrate 1; in the second area 4, the plurality of first signal lines 2011 and the plurality of second signal lines 2012 are alternately arranged along the second direction Y; the first area 3 includes a plurality of sub-areas 5 arranged in sequence in the extension direction of the signal line group 2, and a distance L18 between an edge of at least one sub-area 5 of the plurality of sub-areas 5 away from the display area 101 and the display area 101 is smaller than a distance L19 between an edge of at least one sub-area 5 of the remaining sub-areas 5 of the plurality of sub-areas 5 away from the display area 101 and the display area 101.

[0105] It should be noted that the display area and the display substrate include a plurality of sub-pixel units arranged in an array along the first direction and the second direction, and a plurality of signal lines in the signal line group are used to provide signals to the sub-pixel units in the display area. A signal line in the signal line group that is closest to the display area is electrically connected to the first row of sub-pixels in the second direction and in the direction from the first area to the second area at one end of its extension direction, and a signal line in the signal line group that is farthest from the display area is electrically connected to the last row of sub-pixels in the second direction and in the direction from the first area to the second area at one end of its extension direction, so the number of signal lines in the signal line group gradually decreases in the second direction and in the direction from the first area to the second area.

[0106] In the display substrate provided by the embodiment of the present disclosure, in the first area with a large number of signal lines, the orthographic projections of the plurality of first signal lines on the first substrate overlap with the orthographic projections of the plurality of second signal lines on the first substrate, that is, the plurality of signal lines included in the signal line group are overlapped and wired in the first area, which can save the wiring space of the signal lines and avoid the first peripheral area being too large in the first direction, which is not conducive to achieving a narrow frame. In the second area with a small number of signal lines, the plurality of first signal lines and the plurality of second signal lines are alternately arranged along the first direction, that is, the plurality of first signal lines and the plurality of second signal lines included in the signal line group are alternately wired in the second area. Since the number of signal lines is reduced, the plurality of first signal lines and the plurality of second signal lines can be alternately arranged in the second area without increasing the width of the second peripheral area in the first direction, which avoids the signal lines completely overlapping, resulting in an increase in capacitance and affecting the charging of sub-pixels. Furthermore, since the number of signal lines in the signal line group gradually decreases in the second direction and in the direction from the first area to the second area, the number of signal lines in the multiple sub-areas included in the first area is not exactly the same, the number of signal lines included in at least one sub-area close to the second area is smaller than the number of signal lines included in at least one sub-area far from the second area, and the wiring space required for at least one sub-area close to the second area is smaller than the wiring space required for at least one sub-area far from the second area. Therefore, the distance L18 between the edge of the display area away from the display area and the display area of ​​at least one sub-area among the multiple sub-areas can be set to be smaller than the distance L19 between the edge of the display area away from the display area and the display area of ​​at least one sub-area among the remaining sub-areas, that is, one of the sub-areas is retracted toward the display area relative to another sub-area, and the wiring space on the side of the sub-area away from the display area is increased, which is conducive to setting other structures.

[0107] In some embodiments, Figure 1 As shown, the peripheral area 102 further includes a second peripheral area 103 located at one side of the display area 101 in the second direction Y;

[0108] The signal line group 2 further includes: a third area 10 located in the second peripheral area 103 ; the third area 10 is connected to the first area 3 ; that is, the second area 4 is located on a side of the first area 3 away from the second peripheral area 103 .

[0109] In some embodiments, Figure 2 As shown, the array substrate further includes:

[0110] A plurality of scan lines 6 are located on one side of the first substrate 1 and extend from the display area 101 to the first peripheral area 1021; the plurality of scan lines 6 are arranged along the second direction Y and extend along the first direction X; a signal line 201 in the signal line group 2 is electrically connected to a scan line 6 in the plurality of scan lines 6 at one end of its extension direction.

[0111] In some embodiments, Figure 1 As shown, the second peripheral area 103 includes a binding area 1031 , which includes a plurality of signal terminals (not shown) disposed on one side of the first substrate 1 , and the signal line group is electrically connected to the signal terminals of the binding area 1031 .

[0112] In a specific implementation, the signal terminal of the binding area is bound to the driving chip, and the driving chip provides a scanning signal to the scanning line through the signal line group.

[0113] In some embodiments, Figure 2 , Figure 3 As shown, the first region 3 includes: a plurality of first sub-regions 501, and at least one second sub-region 502; the second sub-region 502 connects two first sub-regions 501;

[0114] In the first sub-region 501, the signal line 201 extends along the second direction Y, and in the second sub-region 502, the signal line 201 extends along the third direction X1; the second direction Y intersects the first direction X; and an angle a1 between the third direction X1 and the direction of the first peripheral region 1021 corresponding to the second sub-region 502 pointing to the display region 101 is greater than 0° and less than 90°.

[0115] It should be noted that Figure 2 The first peripheral area 102 shown in FIG. 1 is a first peripheral area 102-1 on the left side of the display area 101. Figure 3 for Figure 2 A magnified schematic diagram of area A in the middle. Figure 2 The first direction X is a left-right extending direction, the first peripheral area 1021 corresponding to the second sub-area 502 is located on the left side of the display area 101, and the direction from the first peripheral area 1021 corresponding to the second sub-area 502 to the display area 101 is the direction from left to right of the first direction X. The third direction X1 is a direction inclined toward one side of the display area 101.

[0116] It should be noted that Figure 2 In the embodiment, the first sub-region 501 with reference number 501-1 is located on the side of the second sub-region 502 away from the second region (not shown), and the first sub-region 501 with reference number 501-2 is located on the side of the second sub-region 502 close to the second region (not shown). That is, the distance L18 between the edge of the first sub-region 501 with reference number 501-2 away from the display region 101 and the display region 101 is smaller than the distance L19 between the edge of the first sub-region 501 with reference number 501-1 away from the display region 101 and the display region 101.

[0117] That is, in the display substrate provided by the embodiment of the present disclosure, the signal line group extends upward, first changes the extension direction in the second sub-region, and tilts toward the display area side, that is, the second sub-region begins to shrink toward the display area compared to the first sub-region far away from the second area, and can also achieve that the first sub-region close to the second area shrinks toward the display area relative to the first sub-region far away from the second area, and the wiring space of the first sub-region close to the second area away from the display area is increased, which is conducive to the arrangement of other structures.

[0118] In some embodiments, Figure 4 As shown, the second signal line 2012 is located on a side of the first signal line 2011 away from the first substrate 1 .

[0119] It should be noted that Figure 4 for Figure 3 The cross-sectional view along BB'. Figure 4 As shown, the display substrate further includes a first insulating layer 11 located between the first base substrate 1 and the first signal line 2011 , and a second insulating layer 12 located between the second signal line 2012 and the first signal line 2011 .

[0120] In a specific implementation, the sub-pixel unit of the display substrate includes a thin film transistor, and the thin film transistor includes: an active layer, a gate, a source and a drain. The first signal line is, for example, arranged in the same layer as the gate, and the second signal line is, for example, arranged in the same layer as the source and the drain. The thin film transistor can be, for example, a bottom gate structure, that is, the active layer is located on the side of the gate away from the first substrate. Figure 4 In the embodiment, the first insulating layer 11 includes: a buffer layer located between the first substrate and the gate, and the second insulating layer 12 includes a gate insulating layer located between the gate and the active layer. Alternatively, the thin film transistor may be a top gate structure, that is, the active layer is located between the gate and the first substrate. Figure 4 In the embodiment, the first insulating layer 11 includes: a buffer layer located between the first substrate and the active layer, and a gate insulating layer located between the gate and the active layer, and the second insulating layer 12 includes an interlayer insulating layer located between the gate and the source and drain.

[0121] In some embodiments, Figure 2As shown, the number of signal lines 201 included in the second sub-region 502 is less than the number of signal lines 201 in the first sub-region 501 (i.e., Figure 2 The number of signal lines 201 included in the first sub-region 501 (denoted by 501-1 in the figure).

[0122] In specific implementation, Figure 2 As shown, in the first sub-region 501 with reference numeral 501-1, part of the signal lines 201 are no longer extended upward after being electrically connected to the scan line 6, so the number of the signal lines 201 in the first sub-region 501 with reference numeral 501-2 is less than the number of the signal lines 201 included in the second sub-region 502, and accordingly, the number of the signal lines 201 in the first sub-region 501 with reference numeral 501-2 is less than the number of the signal lines 201 in the first sub-region 501 with reference numeral 501-1. The wiring space required for the second sub-region 502 is less than the wiring space required for the first sub-region 501 with reference numeral 501-1, and the signal lines 201 in the second sub-region 502 are inclined toward the display region 101, which will not cause the width of the second peripheral region where the second sub-region is located to increase in the first direction. Correspondingly, the wiring space required for the first sub-region 501 marked with 501-2 connected to the second sub-region 502 is also smaller than the wiring space required for the first sub-region 501 marked with 501-1. After the signal line of the second sub-region 502 is tilted toward the display area, the first sub-region 501 marked with 501-2 shrinks toward the display area relative to the first sub-region 501 marked with 501-1. The wiring space of the first sub-region 501 marked with 501-2 away from the display area 1010 is increased, which is conducive to the arrangement of other structures.

[0123] In some embodiments, Figure 2 As shown, the number of signal lines 201 included in the second sub-region 502 is greater than or equal to the number of signal lines 201 included in the first sub-region 501 connected to the second sub-region 502 on the side close to the second region (ie, the first sub-region 501 marked as 501-2 in the figure).

[0124] It should be noted that Figure 2 In the figure, an example is given in which the number of signal lines 201 included in the second sub-region 502 is equal to the number of signal lines 201 included in the first sub-region 501 connected to the second sub-region 502 on the side close to the second region (that is, the first sub-region 501 marked as 501-2 in the figure), that is, in the first peripheral area 102 corresponding to the second sub-region 502, no signal line 201 is electrically connected to the scan line 6, and all signal lines 201 included in the second sub-region 502 extend upward to the first sub-region 501 marked as 501-2 in the figure.

[0125] Of course, in the specific implementation, it can also be Figure 5 As shown, the number of signal lines 201 included in the second sub-region 502 is less than the number of signal lines 201 included in the first sub-region 501 connected to the second sub-region 502 on the side close to the second region 4, that is, in the first peripheral area 102 corresponding to the second sub-region 502, there is a signal line 201 electrically connected to the scan line 6, and the second sub-region 502 includes the signal line 201 without extending to the first sub-region 501 marked as 501-2 in the figure. Figure 5 In the figure, an example is taken in which a first signal line 2011 in the second sub-region 502 which is closest to the display area 101 is electrically connected to the scan line 6 in the area corresponding to the second sub-region 502, that is, the difference between the number of signal lines 201 included in the second sub-region 502 and the number of signal lines 201 included in the first sub-region 501 marked as 501-2 is 1.

[0126] In some embodiments, Figure 3 As shown, in the first sub-region 501 and the second sub-region 502, the signal line group 2 includes a plurality of sub-groups 9, at least part of the sub-groups 9 include a first signal line 2011 and a second signal line 2012 with overlapping areas in the orthographic projection of the first substrate 1; in the first sub-region 501 and the second sub-region 502, the line widths L4 of the plurality of sub-groups 9 are equal, and the spacings L5 between any two adjacent sub-groups 9 are equal. That is, a first signal line 2011 and a second signal line 2012 with overlapping areas in the orthographic projection of the first substrate 1 are regarded as a sub-group 9.

[0127] In specific implementation, Figure 2 , Figure 5 As shown, the number of subgroups 9 included in the second sub-region 502 is less than the number of subgroups 9 in the first sub-region 501 (i.e. Figure 2 The number of subgroups 9 included in the first subregion 501 (i.e., the first subregion 501 labeled 501-1 in the figure) is less than the number of subgroups 9 included in the first subregion 501 connected to the second subregion 502 on the side close to the second region (i.e., the first subregion 501 labeled 501-2 in the figure), which is smaller than the number of subgroups 9 included in the first subregion 501 (i.e., the first subregion 501 labeled 501-2) connected to the second subregion 502 on the side far from the second region (not shown). Figure 2 The number of subgroups 9 included in the first sub-area 501) marked as 501-1 in the figure.

[0128] In specific implementation, Figure 2As shown, when the number of signal lines 201 included in the second sub-region 502 is equal to the number of signal lines 201 included in the first sub-region 501 connected to the second sub-region 502 on the side close to the second region (i.e., the first sub-region 501 marked as 501-2 in the figure), the number of sub-groups 9 included in the second sub-region 502 is equal to the number of sub-groups 9 included in the first sub-region 501 connected to the second sub-region 502 on the side close to the second region (i.e., the first sub-region 501 marked as 501-2 in the figure).

[0129] In specific implementation, Figure 5 As shown, when the number of signal lines 201 included in the second sub-region 502 is greater than the number of signal lines 201 included in the first sub-region 501 connected to the second sub-region 502 on the side close to the second region (i.e., the first sub-region 501 marked as 501-2 in the figure), and the difference between the number of signal lines 201 included in the second sub-region 502 and the number of signal lines 201 included in the first sub-region 501 connected to the second sub-region 502 on the side close to the second region 4 (i.e., the first sub-region 501 marked as 501-2 in the figure) is less than or equal to 2, the number of sub-groups 9 included in the second sub-region 502 is equal to the number of sub-groups 9 included in the first sub-region 501 connected to the second sub-region 502 on the side close to the second region (i.e., the first sub-region 501 marked as 501-2 in the figure).

[0130] In a specific implementation, when the number of signal lines included in the second sub-region is greater than the number of signal lines included in the first sub-region connected to the second sub-region on a side close to the second region, and the difference between the number of signal lines included in the second sub-region and the number of signal lines included in the first sub-region connected to the second sub-region on a side close to the second region is greater than 2, the number of sub-groups included in the second sub-region is greater than the number of sub-groups included in the first sub-region connected to the second sub-region on a side close to the second region.

[0131] In some embodiments, Figure 3 As shown, in the first sub-region 501 and the second sub-region 502, the orthographic projections of the plurality of first signal lines 2011 on the first substrate 1 and the orthographic projections of the plurality of second signal lines 2012 on the first substrate 1 have overlapping areas;

[0132] In the first sub-region 501 and the second sub-region 502 , the line width of the first signal line 2011 is equal to the line width of the second signal line 2012 , and the spacing between any two adjacent signal lines 201 is equal; the line width of the first signal line 2011 and the line width of the second signal line 2012 are the line width L4 of the sub-group 9 .

[0133] In some embodiments, L4 = 3.5 microns, L5 = 2 microns.

[0134] Of course, in a specific implementation, the line width of the first signal line may be unequal to the line width of the second signal line, the orthographic projection of the first signal line on the first substrate substrate and the orthographic projection of the second signal line on the first substrate substrate have an overlapping area, the orthographic projection of the first signal line on the first substrate substrate falls within the orthographic projection of the second signal line on the first substrate substrate, or the orthographic projection of the second signal line on the first substrate substrate falls within the orthographic projection of the first signal line on the first substrate substrate. The line width of the subgroup is the line width of the wider signal line between the line width of the first signal line and the line width of the second signal line, and the spacing between adjacent subgroups is the spacing between the signal lines with the wider line width.

[0135] In some embodiments, L4 = 3.5 microns, L5 = 2 microns.

[0136] In a specific implementation, when the line width of the first signal line is equal to the line width of the second signal line, the line width of the first signal line and the line width of the second signal line are both 3.5 microns, the spacing between adjacent first signal lines is 2 microns, and the spacing between adjacent second signal lines is 2 microns. When the line width of the first signal line is not equal to the line width of the second signal line, for example, the line width of the first signal line is 3.5 microns, the spacing between adjacent first signal lines is 2 microns, the line width of the second signal lines is both 3 microns, and the spacing between adjacent second signal lines is 2.5 microns.

[0137] In some embodiments, Figure 2 , Figure 5 As shown, of the two first sub-regions 501 connected to the second sub-region 502, the maximum width L26 of the first sub-region 501 far away from the second region (not shown) (i.e., the first sub-region 501 marked as 501-1 in the figure) in the first direction X is greater than the maximum width L27 of the first sub-region 501 close to the second region (i.e., the first sub-region 501 marked as 501-2 in the figure) in the first direction X.

[0138] In specific implementation, Figure 2 , Figure 5 As shown, when the number of signal lines 201 in the first sub-region far away from the second region is greater than the number of signal lines 201 in the first sub-region close to the second region, and when the line width L4 of each sub-group is equal and the spacing L5 between two adjacent sub-groups is equal, L26 is greater than L27.

[0139] In some embodiments, Figure 2 , Figure 5As shown, in the two first sub-regions 501 connected to the second sub-region 502, in the first sub-region 501 far from the second region (i.e., the first sub-region 501 marked as 501-1 in the figure), the signal line 201 closest to the display area 101 at the connection with the second sub-region 502 has a first distance L1 from the display area 101 in the first direction X, and the first sub-region 501 close to the second region 4 (i.e., the first sub-region 501 marked as 501-2 in the figure), the signal line 201 closest to the display area 101 at the connection with the second sub-region 502 has a second distance L2 from the display area 101 in the first direction X, L2 <L1。

[0140] In some embodiments, Figure 2 , Figure 5 As shown, the length of the signal line 201 closest to the display area 101 in the second sub-area 502 in its extension direction is L3; L1, L2, L3 satisfy:

[0141] L2≥L1-L3×cos a1.

[0142] It should be noted that Figure 2 , Figure 5 In the example, L2 = L1-L3 × cos a1 is used for illustration. In the specific implementation, Figure 2 , Figure 5 As shown, when the number of subgroups 9 included in the second subregion 502 is equal to the number of subgroups 9 included in the first subregion 501 (i.e., the first subregion 501 marked as 501-2) connected to the second subregion 502 on one side close to the second region, L2=L1-L3×cos a1. In a specific implementation, when the number of subgroups included in the second subregion is greater than the number of subgroups included in the first subregion connected to the second subregion on one side close to the second region, L2>L1-L3×cos a1.

[0143] In specific implementation, when the width of the second peripheral area in the first direction is determined, and the number of signal lines, line width, and spacing included in the signal line group are determined, L1, L2, and L3 can be specifically set according to the number of sub-groups included in the signal line group in each sub-area and the actual width of the second peripheral area in the first direction.

[0144] In some embodiments, of the two first sub-regions connected to the second sub-region, the first sub-region far from the second region includes m sub-groups, and the first sub-region close to the second region includes n sub-groups, where m>n, and m and n are positive integers;

[0145] The line width L4 of the subgroup, the spacing L5 between adjacent subgroups, the first distance L1, and the second distance L2 satisfy:

[0146] [m×L4+(m-1)×L5]-[n×L4+(n-1)×L5]≤L1-L2.

[0147] It should be noted that, in specific implementation, in different sub-areas, the distance between the signal line closest to the display area and the display area needs to be greater than 0 and greater than a preset value.

[0148] In some embodiments, Figure 6 As shown, between the signal line group 2 and the display area 101, the display substrate further includes an electrostatic unit 7; in the first direction X, the distance between the edge of the electrostatic unit 7 close to the signal line group 2 and the display area 101 is L6; L2 and L6 satisfy: L2-L6 is greater than 0.

[0149] In a specific implementation, in order to prevent the signal lines included in the signal line group from affecting the electrostatic unit, L2-L6 is greater than 2 microns. Preferably, for example, L2-L6 is greater than 3 microns.

[0150] In a specific implementation, if the width of the first peripheral area in the first direction is 0.9 mm, usually, L6 is about 90 microns, and correspondingly, L2 is greater than 92 microns, preferably L2 is greater than 93 microns. In some embodiments, L2 is 140 microns and L1 is 245 microns.

[0151] In a specific implementation, the electrostatic unit includes a plurality of first sub-units and a second sub-unit arranged along a second direction; in the direction from the first area to the second area, the second sub-unit is located on one side of the plurality of first sub-units; for example, a first sub-unit is electrically connected to a corresponding scanning line, and the second sub-unit is electrically connected to a third signal line; the number of first sub-units included in the electrostatic unit is equal to the number of signal lines in the signal line group; the first sub-unit and the second sub-unit, for example, both include thin film transistors.

[0152] In some embodiments, Figure 2 , Figure 3 As shown, the lengths L3 of the plurality of signal lines 201 included in the second sub-region 502 in the extending direction are all equal.

[0153] In some embodiments, Figure 2 As shown, the edge of the second sub-region 502 connected to the first sub-region 501 extends along the fourth direction X2, and the fourth direction X2 and the display area 101 point to the direction of the first peripheral area 1021 corresponding to the second sub-region 502 ( Figure 2 The angle a2 between the first direction in the middle and the direction from right to left is greater than 0° and less than 90°.

[0154] In some embodiments, a1 is greater than or equal to 30° and less than or equal to 60°, and a2 is greater than or equal to 15° and less than or equal to 30°.

[0155] In some embodiments, Figure 2 As shown, a1 is 45° and a2 is 23°.

[0156] In a specific implementation, when L2 is 140 microns, L1 is 245 microns, and a1 is 45°, L3 is approximately 148 microns.

[0157] It should be noted that a1 and a2 can be set according to actual needs. a1 is 45 degrees, which is conducive to ensuring that the extension directions of the multiple subgroups included in the signal line group remain parallel and shrink inward to the display area, and avoids a1 being too large to increase the space required for the second sub-area.

[0158] In some embodiments, Figure 2 , Figure 3 , Figure 5 , Figure 6 As shown, the display substrate also includes:

[0159] The third signal line 8 is located at one side of the first substrate 1 in the peripheral area 102; in the first direction X, the third signal line 8 is located at one side of the signal line group 2 away from the display area 101 in the first peripheral area 1021; the third signal line 8 includes a first portion 801 and a second portion 802; the second portion 802 is at least adjacent to the second sub-area 502 and the first sub-area 501 connected to the second sub-area 502 on the side close to the second area 4;

[0160] like Figure 3 As shown, in the first direction X, the maximum width L20 of the first part 801 is smaller than the maximum width L22 of the second part 802; the second part 802 includes: a first sublayer 8-1, and a second sublayer 8-2 located on the side of the first sublayer 8-1 away from the first substrate 1.

[0161] In some embodiments, the display substrate is an array substrate of a liquid crystal display panel, that is, the sub-pixel unit included in the display substrate also includes a pixel electrode located on the side of the thin film transistor away from the first substrate, and the display substrate also includes a common electrode arranged on the entire surface; the common electrode can be arranged between the pixel electrode and the source and drain, or can be arranged on the side of the pixel electrode away from the first substrate. The third signal line is electrically connected to the common electrode.

[0162] It should be noted that when the display substrate is applied to a liquid crystal display panel, the liquid crystal display panel also includes an opposing substrate arranged opposite to the display substrate, and a packaging glue needs to be arranged in the peripheral area between the display substrate and the opposing substrate, and the packaging glue usually includes supporting silicon (Si) balls. In the related art, the area where the signal line group overlaps the wiring does not include the area that shrinks inward toward the display area, that is, the wiring space on the side of the signal line group away from the display area is small, and the third signal line is a single layer. The thickness of the display substrate in the area where the third signal line is located is less than the thickness of the display substrate in the area where the signal line double-layer overlaps, that is, the thickness uniformity of the display substrate corresponding to the supporting silicon (Si) balls is poor, which easily causes the screen of the display panel to be yellowish.

[0163] In the display substrate provided by the embodiment of the present disclosure, the signal line group begins to shrink inward toward the display area in the second sub-area, and the wiring space of the second sub-area and the first sub-area close to the second area away from the display area is increased, so that the width of the third signal line can be increased in the second sub-area and the first sub-area close to the second area away from the display area, so that the third signal line has enough space for double-layer wiring, that is, including the first sub-layer and the second sub-layer, which is conducive to improving the thickness uniformity of the display substrate in the first peripheral area. In this way, when the display substrate is applied to a liquid crystal display panel, the problem of the yellowing of the screen of the display panel due to the poor thickness uniformity of the display substrate corresponding to the supporting silicon ball can be alleviated or even avoided, thereby improving the display effect. In addition, the increase in the width of the second part of the third signal line is also conducive to increasing the resistance of the third signal line and thus alleviating the voltage drop of the third signal line.

[0164] In some embodiments, Figure 3 As shown, the edge of the second portion 802 adjacent to the second sub-region 502 is parallel to the extension direction of the signal line included in the second sub-region 502. That is, the edge of the second portion adjacent to the second sub-region extends along the third direction.

[0165] In some embodiments, Figure 3 As shown, in the first peripheral region, the spacings between the second portion 802 and different sub-regions 5 of the signal line group 2 are substantially equal.

[0166] It should be noted that the spacing between the second part and different sub-regions of the signal line group is roughly equal, which means that the difference in spacing between the second part and different sub-regions of the signal line group is within a reasonable process error range, and the spacing between the second part and different sub-regions of the signal line group can be regarded as equal.

[0167] For example, Figure 3 As shown, the distance L24 between the second portion 802 and the second sub-region 502 is equal to the distance L25 between the second portion 802 and the first sub-region 501 - 2 .

[0168] In some embodiments, Figure 3As shown, in the first peripheral region, the distance L23 between the first portion 801 and the first sub-region 501 - 1 of the signal line group 2 is equal to the distance L25 between the second portion 802 and the first sub-region 501 - 2 .

[0169] In specific implementation, when L23=L24=L25, L22-L20≤L2-L1; if L2 is 140 microns and L1 is 245 microns, then L22-L20≤105 microns, which can be set to L22-L20=105 microns, that is, the line width of the second part is increased by 105 microns compared with the first part.

[0170] In some embodiments, Figure 3 As shown, the orthographic projection pattern of the first sub-layer 8 - 1 on the first base substrate 1 is in a grid shape, that is, the first sub-layer 8 - 1 includes a plurality of first opening areas 13 .

[0171] It should be noted that when the display substrate is applied to a liquid crystal display panel, the encapsulation glue is usually a UV curing glue, that is, UV light irradiation is required after the glue is applied. The orthographic projection pattern of the first sublayer on the first base substrate is a grid shape, which is conducive to improving the transmittance of UV light and improving the curing yield of the UV curing glue.

[0172] In some embodiments, Figure 3 , Figure 4 As shown, the orthographic projection of the second sub-layer 8 - 2 on the first substrate 1 falls within the orthographic projection of the first sub-layer 8 - 1 on the first substrate.

[0173] In specific implementation, Figure 3 , Figure 4 As shown, the orthographic projection of the second sub-layer 8-2 on the first base substrate 1 falls within the orthographic projection of the grid pattern of the first sub-layer 8-1 on the first base substrate. Figure 3 , Figure 4 As shown, the orthographic projection of the second sub-layer 8-2 on the first base substrate 1 does not overlap with the orthographic projection of the first opening area 13 on the first base substrate, thereby preventing the second sub-layer from affecting the transmittance of ultraviolet light.

[0174] Alternatively, in the second part, the orthographic projection of the second sub-layer on the first base substrate may coincide with the orthographic projection of the first sub-layer grid pattern on the first base substrate.

[0175] In some embodiments, Figure 3 , Figure 4 As shown, the first sub-layer 8 - 1 is disposed on the same layer as the first signal line 2011 , and the second sub-layer 8 - 2 is disposed on the same layer as the second signal line 2012 .

[0176] In some embodiments, Figure 3 As shown, the first portion 801 includes only the first sub-layer 8 - 1 .

[0177] In some embodiments, Figure 7 As shown, the first region 3 includes a second sub-region 502; the display area 101 includes a first edge 1011 extending along the first direction X; the extension line of the first edge 1011 is located on a side of the first region 3 away from the second region 4;

[0178] In the second direction Y, there is a third distance L7 between the connection b1 between the signal line 201 in the second sub-region 502 closest to the display area 101 and the first sub-region 501 far away from the second region 4 and the first edge 1011; the third distance L7 and the width L8 of the display area 101 in the second direction Y satisfy: L7=L8 / 3.

[0179] It should be noted that the display area involved in the embodiment of the present disclosure corresponds to the area where the image is displayed when the display substrate is applied to a display product, and the peripheral area involved in the embodiment of the present disclosure corresponds to the area where no image display is required.

[0180] Or, in some embodiments, Figure 8 As shown, the first area 3 includes two second sub-areas 502, and the reference numbers of the two second sub-areas 502 are 502-1 and 502-2 respectively; the display area 101 includes a first edge 1011 extending along the first direction X; the extension line of the first edge 1011 is located on the side of the first area 3 away from the second area 4;

[0181] In the second direction Y, in the second sub-region 502 away from the second area 4 (i.e., the second sub-region 502 with reference numerals 502-1, respectively), there is a fourth distance L9 between a connection b4 between the signal line 201 closest to the display area 101 and the first sub-region 501 away from the second area 4 (i.e., the first sub-region 501 with reference numerals 501-1, respectively) and the first edge 1011; in the second direction Y, in the second sub-region 502 close to the second area (i.e., the second sub-region 502 with reference numerals 502-2, respectively), there is a fifth distance L10 between a connection b5 between the signal line 201 closest to the display area 101 and the first sub-region 501 away from the second area 4 (i.e., the first sub-region 501 with reference numerals 501-2, respectively) and the first edge 1011; the fourth distance L9 and the width L8 of the display area 101 in the second direction Y satisfy: L9=L8 / 4; the fifth distance L10 and the width L8 of the display area 101 in the second direction Y satisfy: L10=L8 / 2.

[0182] It should be noted that the display area is a rectangle, the sides of the rectangle are the edges of the display area, a pair of edges of the display area extend along the first direction X, and the other pair of edges extend along the second direction Y. The display area includes a first edge extending along the first direction X, which is the boundary between the display area and the second peripheral area.

[0183] The first area includes two second sub-areas, that is, the signal line group is retracted twice in the first area toward one side of the display area.

[0184] In a specific implementation, the first area may also include more second sub-areas, that is, the signal line group is retracted more times in the first area toward the display area. It should be noted that the number of second sub-areas included in the first area, that is, the number of times the signal line group is retracted in the first area toward the display area, can be specifically set according to the number of signal lines included in the signal line group and the size of the first peripheral area, as long as there is enough wiring space in the direction in which the signal line group extends after the number of signal lines is reduced so that L2 meets the requirements after the signal line group is retracted.

[0185] In the display substrate provided by the embodiment of the present disclosure, when the first area includes two second sub-areas, L9 is smaller than L7 compared to the case where the first area includes one second sub-area. Accordingly, when the first area includes two second sub-areas, the length of the first part of the third signal line in the second direction is smaller than the length of the first part of the third signal line in the second direction when the first area includes one second sub-area. That is, when the first area includes two second sub-areas, the first part of the third signal line arranged in a single layer occupies a smaller area, which is more conducive to improving the uniformity of the thickness of the display substrate in the peripheral area and avoiding the problem of yellowing of the display.

[0186] In some embodiments, Figure 7 , Fig. 9 As shown, the first area 3 further includes: a third sub-area 503, and the second area 4 includes: a fourth sub-area 504 connected to the third sub-area 503; the third sub-area 503 is connected to the first sub-area 501 closest to the second area 4 (i.e., the first sub-area 501 marked as 501-2 in the figure);

[0187] The signal line 201 in the fourth sub-region 504 extends along the second direction Y, and at least part of the signal line 201 in the third sub-region 503 includes a part extending along the fifth direction X3. The angle a3 between the fifth direction X3 and the direction of the display area 101 pointing to the side of the first peripheral area 1021 corresponding to the second sub-region 502 is greater than 0° and less than 90°.

[0188] It should be noted that Fig. 9 for Figure 7 Enlarged schematic diagram of area C in the middle.

[0189] It should be noted that the signal line group continues to extend upward after passing through the first sub-region close to the second region, and the number of signal lines included in the signal line group continues to decrease as the signal line group extends upward. The number of signal lines included in the fourth sub-region is much smaller than the maximum number of signal lines included in the first region. There is no need to increase the width of the second peripheral area in the first direction. In the fourth sub-region included in the second region, multiple first signal lines and multiple second signal lines can be alternately arranged in the second region, thereby avoiding signal line overlap, which leads to increased capacitance and affects sub-pixel charging.

[0190] In the display substrate provided by the embodiment of the present disclosure, the signal line group extends to the third sub-region and changes the extension direction. The signal line closest to the display area extends along the fifth direction and deviates toward one side of the display area, so that multiple signal lines have enough space in the fourth sub-region to be arranged alternately, thereby avoiding signal line overlap, which leads to increased capacitance and affects sub-pixel charging.

[0191] In some embodiments, Figure 7 As shown, the number of signal lines 201 included in the third sub-region 503 is less than the number of signal lines 201 included in the first sub-region 501 closest to the second region 4 (ie, the first sub-region 501 marked as 501 - 2 ).

[0192] Correspondingly, such as Figure 7 As shown, the number of signal lines 201 included in the fourth sub-region 504 is less than the number of signal lines 201 included in the first sub-region 501 closest to the second region 4 (ie, the first sub-region 501 marked as 501 - 2 ).

[0193] In some embodiments, Figure 7 As shown, the number of signal lines 201 included in the fourth sub-region 504 is less than or equal to the number of signal lines 201 included in the third sub-region 503 .

[0194] It should be noted that Figure 7 In the example, the number of signal lines 201 included in the fourth sub-region 504 is equal to the number of signal lines 201 included in the third sub-region 503. In the first peripheral area 102 corresponding to the third sub-region 503, no signal line 201 is electrically connected to the scan line 6, and all signal lines 201 included in the third sub-region 503 extend upward to the fourth sub-region 504.

[0195] Of course, in a specific implementation, the number of signal lines included in the fourth sub-region can also be made smaller than the number of signal lines included in the third sub-region, that is, in the first peripheral area corresponding to the third sub-region, there is a signal line electrically connected to the scan line, and the signal line included in the third sub-region does not need to extend to the fourth sub-region.

[0196] Since in the fourth sub-area, the first signal lines and the second signal lines are arranged alternately along the first direction, in some embodiments, such as Figure 7 As shown, the minimum width L28 of the first sub-region 501 closest to the second region 4 (ie, the first sub-region 501 labeled 501 - 2 ) in the first direction X is smaller than the maximum width L29 of the fourth sub-region 504 in the first direction X.

[0197] In some embodiments, Figure 7 As shown, the signal line 201 in the first sub-region 501 (ie, the first sub-region 501 marked as 501 - 2 ) connected to the third sub-region 503 and the signal line 201 in the fourth sub-region 504 that is away from the display area 101 are located in the same straight line.

[0198] That is, the extension direction and extension position of a signal line in the signal line group farthest from the display area do not change after passing through the third sub-area and the fourth sub-area, that is, the signal line in the fourth sub-area farthest from the display area does not need to be retracted, providing sufficient wiring space for the first signal line and the second signal line to be alternately arranged along the first direction.

[0199] In some embodiments, Figure 7 As shown, in the first direction X, the signal line 201 closest to the display area 101 in the first sub-area 501 closest to the second area 4 (i.e., the first sub-area 501 marked as 501-2) has a sixth distance L11 from the connection between the signal line 201 and the third sub-area 503 to the display area 101, the signal line 201 closest to the display area 101 in the fourth sub-area 504 has a seventh distance L12 from the display area 101, and the signal line 201 closest to the display area 101 in the third sub-area 501 has a length L13 in its extension direction;

[0200] L11, L12, L13 meet the following requirements:

[0201] L12 <L11;

[0202] L12 ≥ L11 - L13 × cos a3.

[0203] It should be noted that Figure 7 In the example, L12 = L11-L13 × cos a3 is used for illustration. In the specific implementation, Figure 7 As shown, when twice the number of subgroups 9 included in the third subregion 503 is equal to the number of signal lines 2 included in the fourth subregion 504, L12=L11-L13×cos a3. In a specific implementation, when twice the number of subgroups included in the third subregion is greater than the number of signal lines included in the fourth subregion, L12>L11-L13×cos a3.

[0204] In specific implementation, when the width of the second peripheral area in the first direction is determined, and the number of signal lines included in the signal line group, the line width, and the spacing are determined, L11, L12, and L13 can be specifically set according to the number of signal lines included in each sub-area of ​​the signal line group and the actual width of the second peripheral area in the first direction.

[0205] In some embodiments, Figure 7 As shown, in the first sub-area 501 and the third sub-area 503, the signal line group 2 includes a plurality of sub-groups 9;

[0206] like Fig. 9 As shown, in the fourth sub-region 504 , the first signal line 2011 has a first line width L14 , the second signal line 2012 has a second line width L15 , and the distance between the first signal line 2011 and the second signal line 2012 is L16 .

[0207] In some embodiments, the first sub-region 501 closest to the second region 4 includes k sub-groups, and the fourth sub-region includes e1 first signal lines and e2 second signal lines; e1, e2, and k are positive integers, and e1+e2<2k;

[0208] e1, e2, k, L11, L12, L14, L15, L16, the line width L4 of subgroup 9, and the spacing L5 between adjacent subgroups 9 satisfy:

[0209] [e1×L14+e2×L15+(e1+e2-1)×L16]-[k×L4+(k-1)×L5]≤L11-L12.

[0210] It should be noted that k is used here to represent the number of subgroups included in the first subregion closest to the second region. The "first subregion far away from the second region includes m subgroups" mentioned in the previous text, when the first subregion far away from the second region is the first subregion closest to the second region, k=m.

[0211] In some embodiments, L4=3.5 microns, L5=2 microns; L14=3.5 microns, L15=3 microns, L16=1.25 microns.

[0212] It should be noted that, in specific implementation, in different sub-areas, the distance between the signal line closest to the display area and the display area needs to be greater than 0 and greater than a preset value.

[0213] In some embodiments, when the display substrate further includes an electrostatic unit, L12 and L6 satisfy: L12-L6 is greater than 0.

[0214] In a specific implementation, in order to prevent the signal lines included in the signal line group from affecting the electrostatic unit, L12-L6 is greater than 2 microns. Preferably, for example, L12-L6 is greater than 3 microns.

[0215] In a specific implementation, if the width of the first peripheral area in the first direction is 0.9 mm, usually, L6 is about 90 microns, and correspondingly, L12 is greater than 92 microns, preferably L12 is greater than 93 microns. In some embodiments, L12 is 285 microns.

[0216] In some embodiments, Figure 7 As shown, in the direction in which the first peripheral area 1021 corresponding to the third sub-area 503 points to the display area 101, the length of the multiple first signal lines 2011 included in the third sub-area 503 gradually increases in its extension direction, and the length of the multiple second signal lines 2012 included in the third sub-area 503 gradually increases in its extension direction.

[0217] In some embodiments, Figure 7 As shown, the edge of the connection between the third sub-region 503 and the first sub-region 501 (i.e., the first sub-region 501 labeled 501-2 in the figure) extends along the ninth direction X4, and the angle a4 between the ninth direction X4 and the direction of the display area 101 pointing to the first peripheral area 1021 corresponding to the second sub-region 502 is greater than 0° and less than 90°;

[0218] The edge of the connection between the third sub-region 503 and the fourth sub-region 504 extends along the sixth direction X5, and an angle a5 between the sixth direction X5 and the direction of the first peripheral region 1021 corresponding to the second sub-region 502 pointing to the display region 101 is greater than 0° and less than 90°.

[0219] In some embodiments, a3 is greater than or equal to 30° and less than or equal to 60°, a4 is greater than or equal to 15° and less than or equal to 30°, and a5 is greater than or equal to 5° and less than or equal to 15°.

[0220] In some embodiments, a3 is 45°, a4 is 22.5°, and a5 is 8°.

[0221] It should be noted that a3, a4, and a5 can be set according to the actual wiring space of the third sub-region and the fourth sub-region.

[0222] In some embodiments, Figure 7 As shown, the first region 3 includes a second sub-region 502; the display area 101 includes a first edge 1011 extending along the first direction X; the extension line of the first edge 1011 is located on a side of the first region 3 away from the second region 4;

[0223] In the second direction Y, there is an eighth distance L17 between the connection b2 between the signal line 201 closest to the display area 101 in the third sub-area 503 and the first sub-area 501 (i.e., the first sub-area 501 marked as 501-2 in the figure) and the first edge 1011; the eighth distance L17 and the width L8 of the display area 101 in the second direction Y satisfy: L17=2×L8 / 3.

[0224] Or, in some embodiments, Figure 8 As shown, the first area 3 includes two second sub-areas 502; the display area 101 includes a first edge 1011 extending along the first direction X; the extension line of the first edge 1011 is located on a side of the first area 3 away from the second area 4;

[0225] In the second direction Y, there is an eighth distance L17 between the connection between the signal line 201 closest to the display area 101 in the third sub-area 503 and the first sub-area 501 (i.e., the first sub-area 501 marked as 501-3 in the figure) and the first edge 1011; the eighth distance L17 and the width L8 of the display area 101 in the second direction Y satisfy: L17=3×L8 / 4.

[0226] In some embodiments, Fig. 9 As shown, the second portion 802 is adjacent to the third sub-region 503 and the fourth sub-region 504 .

[0227] In some embodiments, the extension direction of at least a portion of the second portion close to the edge of the signal line group is parallel to the extension direction of the signal lines in the third sub-region and the fourth sub-region farthest from the display area.

[0228] In some embodiments, Fig.10 As shown, the second area 4 also includes an eighth sub-area 508 and a ninth sub-area 509; the eighth sub-area 508 connects the fourth sub-area 504 and the ninth sub-area 509; the extension direction of the signal line in the eighth sub-area 508 intersects with the second direction Y and the first direction X; the distance L34 between the edge of the ninth sub-area 509 away from the display area 101 and the display area 101 is less than the distance L35 between the edge of the fourth sub-area 504 away from the display area 101 and the display area 101.

[0229] In the display substrate provided by the embodiment of the present disclosure, the signal line group starts to shrink inward toward the display area in the eighth sub-area of ​​the second area, and the width of the second part adjacent to the eighth sub-area and the ninth area is further increased, which is more conducive to increasing the resistance of the third signal line and thereby alleviating the voltage drop of the third signal line.

[0230] In some embodiments, Figure 1As shown, the peripheral area 102 further includes a third peripheral area 104 located on one side of the display area 101 in the second direction Y; the third peripheral area 104 is located above the display area 101; Figure 1 The enlarged schematic diagram of the E area is shown in Fig.11 As shown, in the third peripheral area 104, the extension direction of the edge of the second portion 802 of the third signal line 8 on the side away from the signal line group 2 intersects both the first direction X and the second direction Y, and the extension direction of the edge is deflected toward the display area, that is, in the third peripheral area 104, the second portion 802 is retracted toward the display area 101, so that space can be reserved on the side of the second portion 802 away from the display area 101 to arrange other structures, such as Fig.11 The dummy structure 21 in the circuit prevents static electricity accumulation.

[0231] In some embodiments, Figure 1 As shown, the peripheral area 102 further includes a second peripheral area 103 located at one side of the display area 101 in the second direction Y;

[0232] The third region 10 includes a fifth sub-region 505 and a sixth sub-region 506;

[0233] The fifth sub-region 505 connects the sixth sub-region 506 and the first region 3, the signal line 201 in the fifth sub-region 505 extends along the second direction Y, and the extension direction of at least a part of the signal line 201 in the sixth sub-region 506 intersects the second direction Y and the first direction X;

[0234] In the fifth sub-region 505, the orthographic projections of the plurality of first signal lines 2011 on the first substrate 1 overlap with the orthographic projections of the plurality of second signal lines 2012 on the first substrate 1; in the sixth sub-region 506, the plurality of first signal lines 2011 and the plurality of second signal lines 2012 are alternately arranged along the first direction X.

[0235] In some embodiments, Figure 1 As shown, the third area 10 also includes a tenth sub-area 510; the tenth sub-area 510 is connected to the sixth sub-area 506 and the signal terminal (not shown) of the binding area 1031; in the tenth sub-area 510, the plurality of first signal lines 2011 and the plurality of second signal lines 2012 are alternately arranged along the first direction X, and the plurality of first signal lines 2011 and the plurality of second signal lines 2012 extend along the second direction Y.

[0236] In a specific implementation, the signal line group is led out from the binding area of ​​the second peripheral area, and before reaching the first peripheral area, the number of signal lines included in the signal line group in different sub-areas remains unchanged. In the second peripheral area, the signal line group has sufficient wiring space, so in the part electrically connected to the signal terminal, that is, the tenth sub-area, the signal lines included in the signal line group can be alternately wired, that is, the first signal line and the second signal line are arranged alternately, so as to avoid the signal line overlap causing the capacitance to increase and affect the sub-pixel charging. When the signal line group extends to the first peripheral area, the wiring space of the first area where the total number of signal lines remains unchanged becomes smaller, so the signal line group adopts overlapping wiring in the first area. In the second peripheral area, the fifth sub-area connected to the signal line group and the first area also adopts overlapping wiring, that is, the signal line group is alternately wired along the first direction in the tenth sub-area, changes the extension direction to the sixth sub-area, and changes the extension direction again to the fifth sub-area and turns to overlapping wiring. Compared with directly changing from alternating wiring to overlapping wiring at the boundary between the second peripheral area and the first peripheral area, it is conducive to the rational use of the space of the second peripheral area and reduces the wiring difficulty.

[0237] In a specific implementation, the extension direction of any signal line in the signal line group in the fifth sub-region and the extension direction of the signal line in the signal line group in the first sub-region connected to the fifth sub-region are located in the same straight line, that is, the extension direction of the signal line group through the fifth sub-region and the first sub-region connected to the fifth sub-region remains unchanged.

[0238] Or, in some embodiments, Fig.12 , Fig.13 As shown, in the second peripheral area 103, the third region 10 further includes: a seventh sub-region 507 connected to the sixth sub-region 506; the seventh sub-region 507 connects the sixth sub-region 506 and the tenth sub-region 510;

[0239] The extension direction of the signal line 201 in the seventh sub-region 507 intersects with the second direction Y, and the extension direction of the signal line 201 in the seventh sub-region 507 intersects with the extension direction of the signal line 201 in the sixth sub-region 506;

[0240] In the seventh sub-region 507 , a plurality of first signal lines 2011 and a plurality of second signal lines 2012 are alternately arranged along the first direction X.

[0241] That is, in the second peripheral area, the signal line group extends along the second direction in the tenth sub-area, changes the extension direction once in the seventh sub-area, changes the extension direction again in the sixth sub-area, and returns to the second direction in the fifth sub-area, and turns to overlapping wiring. In specific implementation, the number of times the extension direction needs to be changed between the tenth sub-area and the fifth sub-area can be selected according to the number of signal lines and the actual wiring space of the signal line group.

[0242] It should be noted that Fig.13 for Fig.12 A magnified schematic diagram of region D in the middle.

[0243] In some embodiments, Fig.12 As shown, the edge of the connection between the sixth sub-region 506 and the fifth sub-region 505 extends along the seventh direction X7, and the angle a6 between the seventh direction X7 and the direction from the display area 101 to the first peripheral area 1021 is greater than 0° and less than 90°;

[0244] The edge of the connection between the sixth sub-region 506 and the seventh sub-region 507 extends along the eighth direction X8, and an angle a7 between the eighth direction X8 and the direction from the display region 101 to the first peripheral region 1021 is greater than 0° and less than 90°.

[0245] In some embodiments, Fig.12 As shown, the seventh direction X7 is parallel to the eighth direction X8; the included angles a8, a6, and a7 between the extension direction of at least a portion of the signal line 201 in the sixth sub-region 506 and the first direction X are all 45°.

[0246] In some embodiments, Fig.12 As shown, the included angle a9 between the extension direction X6 of at least a part of the signal line 201 in the seventh sub-region 507 and the first direction X is greater than 0° and less than a8=45°.

[0247] In some embodiments, Fig.12 As shown, the distance from the signal line 201 of the fifth sub-region 505 closest to the display area 101 to the display area 101 is L30; in the second direction Y, in the sixth sub-region 506, the distance from the connection b6 of the signal line 201 closest to the display area and the fifth sub-region 505 to the display area 101 is L31; in the sixth sub-region 506, the distance from b7 to b6 of the connection between the signal line 201 closest to the display area and the seventh sub-region 507 is L32, and in the sixth sub-region 506, the distance from the connection b8 of the signal line 201 farthest from the display area and the fifth sub-region 505 to the display area 101 is L33; for example, L33 is greater than or equal to 680 microns and less than or equal to 690 microns, L31 is approximately 200 microns, and L32 is approximately 230 microns; if the display substrate includes an electrostatic unit, L30 is greater than or equal to 92 microns, and preferably L30 is greater than 93 microns.

[0248] In some embodiments, Figure 1 As shown, the display substrate includes two signal line groups 2 , and the two signal line groups 2 correspond to two first peripheral areas 1021 respectively.

[0249] In some embodiments, when the display substrate includes two signal line groups, one of the two signal line groups is electrically connected to the odd-numbered scan lines, and the other of the two signal line groups is electrically connected to the even-numbered scan lines.

[0250] In some embodiments, Figure 1 As shown, the display substrate further includes a ground level signal line 14 , which is located at a side of the third signal line 8 away from the display area 101 .

[0251] In specific implementation, Figure 1 As shown, the ground level signal line 14 and the third signal line 8 are both electrically connected to the binding end (not shown) of the binding area 1031; the display substrate also includes a third peripheral area 104 located on the side of the display area 101 away from the second peripheral area 103; the third signal line 8 is led out from one side of the binding area 1031 of the second peripheral area 103, extends to the first peripheral area 102-1, the third peripheral area 104, the first peripheral area 102-2 and then returns to the other side of the binding area 1031 of the second peripheral area 103; the ground level signal line 14 is led out from one side of the binding area 1031 of the second peripheral area 103, extends to the first peripheral area 102-1, the third peripheral area 104, the first peripheral area 102-2 and then returns to the other side of the binding area 1031 of the second peripheral area 103.

[0252] Based on the same inventive concept, the embodiment of the present disclosure also provides a display device, such as Fig.14 As shown, the display device includes:

[0253] The display substrate 15 provided in the embodiment of the present disclosure;

[0254] An opposite substrate 16, arranged opposite to the display substrate 15;

[0255] The liquid crystal layer 17 is located between the display substrate 15 and the counter substrate 16 .

[0256] In some embodiments, Fig.15 As shown, the display substrate includes a third signal line 8, and the third signal line 8 includes a second portion 802;

[0257] The display panel also includes:

[0258] A plurality of support portions 18 are located between the display substrate 15 and the opposite substrate 16 ; the orthographic projection of the support portion on the first base substrate 1 overlaps with the orthographic projection of the second portion 802 on the first base substrate 1 .

[0259] In specific implementation, Fig.15 As shown, at least part of the orthographic projection of the supporting portion 18 on the first substrate 1 overlaps with the orthographic projection of the second sub-layer 8 - 2 and the first sub-layer 8 - 1 included in the second portion 802 on the first substrate 1 .

[0260] In the display device provided by the embodiment of the present disclosure, the orthographic projection of the supporting part on the first base substrate overlaps with the orthographic projection of the second part on the first base substrate. Since the double-layer wiring of the second part of the signal line includes the first sublayer and the second sublayer, the thickness uniformity of the display substrate in the peripheral area is better, which can alleviate or even avoid the problem of the screen of the display device being yellowish due to the poor thickness uniformity of the display substrate corresponding to the supporting part, thereby improving the display effect.

[0261] In specific implementation, Fig.15 As shown, a packaging glue 19 is provided between the display substrate 15 and the opposite substrate 16 and includes a plurality of supporting parts 18. The supporting parts 18 are, for example, silicon balls included in the packaging glue 19.

[0265] In some embodiments, the display device provided in the embodiments of the present disclosure may further include a backlight module located on the light incident side of the display substrate, and the backlight module may be a direct-type backlight module or an edge-type backlight module.

[0266] In a specific implementation, the side-entry backlight module may include a light bar, a reflective sheet, a light guide plate, a diffuser, a prism group, etc., and the light bar is located on one side of the thickness direction of the light guide plate.

[0267] The display device provided in the embodiment of the present disclosure is any product or component with a display function, such as a mobile phone, a tablet computer, a television, a display, a laptop computer, a digital photo frame, a navigator, etc. Other essential components of the display device should be understood by a person skilled in the art, and will not be described in detail here, nor should they be used as a limitation of the present disclosure. The implementation of the display device can refer to the embodiment of the display panel above, and the repeated parts will not be described in detail.

[0268] In summary, in the display substrate, display panel and display device provided by the embodiments of the present disclosure, in the first area with a large number of signal lines, the orthographic projections of the plurality of first signal lines on the first substrate overlap with the orthographic projections of the plurality of second signal lines on the first substrate, that is, the plurality of signal lines included in the signal line group are wired in an overlapping manner in the first area, which can save the wiring space of the signal lines and avoid the first peripheral area being too large in the first direction, which is not conducive to achieving a narrow frame. In the second area with a small number of signal lines, the plurality of first signal lines and the plurality of second signal lines are alternately arranged along the second direction, that is, the plurality of first signal lines and the plurality of second signal lines included in the signal line group are wired alternately in the second area. Since the number of signal lines is reduced, the plurality of first signal lines and the plurality of second signal lines can be alternately arranged in the second area without increasing the width of the second peripheral area in the first direction, which avoids the signal lines completely overlapping, resulting in an increase in capacitance and affecting the charging of sub-pixels. Furthermore, since the number of signal lines in the signal line group gradually decreases in the second direction and in the direction from the first area to the second area, the number of signal lines in the multiple sub-areas included in the first area is not exactly the same, the number of signal lines included in at least one sub-area close to the second area is smaller than the number of signal lines included in at least one sub-area far from the second area, and the wiring space required for at least one sub-area close to the second area is smaller than the wiring space required for at least one sub-area far from the second area. Therefore, the distance L18 between the edge of the display area away from the display area and the display area of ​​at least one sub-area among the multiple sub-areas can be set to be smaller than the distance L19 between the edge of the display area away from the display area and the display area of ​​at least one sub-area among the remaining sub-areas, that is, one of the sub-areas is retracted toward the display area relative to another sub-area, and the wiring space on the side of the sub-area away from the display area is increased, which is conducive to setting other structures.
