Description

Technical Field

[0001] This disclosure relates to the field of display technology, and more particularly to display substrates, display panels, and display devices. Background Technology

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

[0003] Signal lines are typically required around the perimeter of display products. For low-resolution products, single-layer or alternating double-layer wiring is used for the signal lines on the left and right sides. However, for narrow-bezel products with left and right bezels less than 1 mm and high resolution, a large number of signal lines need to be set up around the bezels. The 1 mm left and right bezels cannot accommodate single-layer or alternating double-layer wiring. Summary of the Invention

[0098] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. Furthermore, the embodiments and features in the embodiments of this disclosure can be combined with each other without conflict. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0099] Unless otherwise defined, the technical or scientific terms used in this disclosure shall have the ordinary meaning understood by one of ordinary skill in the art to which this disclosure pertains. The terms “first,” “second,” and similar terms used in this disclosure do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as “comprising” or “including” mean that an element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects. Terms such as “connected” or “linked” are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect.

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

[0101] In related technologies, for low-resolution display products, signal lines in the peripheral areas on both sides of the display area are laid out using single-layer wiring or alternating double-layer wiring. However, for narrow-bezel products with left and right bezels less than 1 mm and high resolution, a large number of signal lines need to be set on each side bezel, and the 1 mm left and right bezels cannot provide sufficient wiring space for single-layer wiring or alternating double-layer wiring. If multiple signal lines on one side of the display area are laid out using double-layer overlapping wiring, that is, the orthographic projections of signal lines on different layers have overlapping areas, it will cause a parallel plate capacitor to 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 overlapping wiring method will make the capacitance of the overlapping area of ​​the orthographic projection of the signal lines twice that of single-layer wiring, affecting the pixel charging rate.

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

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

[0104] At least one signal line group 2, located at least in the first peripheral region 1021 on one side of the first substrate 1, includes multiple signal lines 201; the multiple signal lines 201 include: multiple first signal lines 2011 arranged along a first direction X, and multiple second signal lines 2012 located on a different layer from the multiple first signal lines 2011 and arranged along the first direction X; in the first peripheral region 1021, the signal line group 2 includes a first region 3 and a second region 4 arranged in its extending direction; the number of signal lines included in the first region 3 is greater than the number of signal lines included in the second region 4; in the first region 3, the multiple 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 region 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 region 3 includes a plurality of sub-regions 5 arranged sequentially in the extension direction of the signal line group 2, and the distance L18 between the edge of at least one of the plurality of sub-regions 5 away from the display area 101 and the display area 101 is less than the distance L19 between the edge of at least one of the remaining sub-regions 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 multiple sub-pixel units arranged in an array along a first direction and a second direction. Multiple signal lines in the signal line group are used to provide signals to the sub-pixel units in the display area. The signal line closest to the display area in the signal line group is electrically connected at one end of its extension direction to the first row of sub-pixels in the second direction, pointing from the first region to the second region. The signal line furthest from the display area in the signal line group is electrically connected at one end of its extension direction to the last row of sub-pixels in the second direction, pointing from the first region to the second region. Therefore, the number of signal lines in the signal line group gradually decreases in the second direction, pointing from the first region to the second region.

[0106] The display substrate provided in this embodiment features a first region with a large number of signal lines. The projections of multiple first signal lines onto the first substrate overlap with the projections of multiple second signal lines onto the first substrate. This means that the signal lines in a signal line group overlap and are routed in the first region, saving wiring space and preventing the first peripheral region from becoming too large in the first direction, which would hinder the achievement of a narrow bezel. In a second region with a smaller number of signal lines, multiple first and second signal lines are arranged alternately along the first direction. This means that the signal lines in a signal line group alternately routed in the second region. Because the number of signal lines is reduced, it is not necessary to increase the width of the second peripheral region in the first direction to achieve the alternating arrangement of multiple first and second signal lines in the second region, avoiding complete overlap of signal lines that would increase capacitance and affect sub-pixel charging. 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 region to the second region, the number of signal lines in the multiple sub-regions included in the first region is not exactly the same. The number of signal lines in at least one sub-region close to the second region is less than the number of signal lines in at least one sub-region far from the second region. The wiring space required for at least one sub-region close to the second region is less than the wiring space required for at least one sub-region far from the second region. Therefore, the distance L18 between the edge of at least one sub-region far from the display area and the display area can be set to be less than the distance L19 between the edge of at least one sub-region far from the display area and the display area in the remaining sub-regions. That is, one sub-region is recessed towards the display area relative to another sub-region, and the wiring space on the side of the sub-region far from the display area is increased, which is beneficial for setting up other structures.

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

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

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

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

[0111] In some embodiments, such as Figure 1 As shown, the second peripheral region 103 includes a bonding region 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 bonding region 1031.

[0112] In practice, the signal terminals in the bonding area are bonded to the driver chip, and the driver chip provides scanning signals to the scan lines through the signal line group.

[0113] In some embodiments, such as 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 with the first direction X. The angle α1 between the third direction X1 and the direction from the first peripheral area 1021 corresponding to the second sub-region 502 to the display area 101 is greater than 0° and less than 90°.

[0115] It should be noted that, Figure 2 The first peripheral area 102 shown is the first peripheral area 102-1 on the left side of the display area 101. Figure 3 for Figure 2 An enlarged schematic diagram of region A in the middle. Figure 2 The first direction X is the left-right extension direction. The first peripheral area 1021 corresponding to the second sub-region 502 is located to the left of the display area 101. The direction in which the first peripheral area 1021 corresponding to the second sub-region 502 points to the display area 101 is the left-to-right direction of the first direction X. The third direction X1 is the direction that tilts towards one side of the display area 101.

[0116] It should be noted that, Figure 2 In the figure, the first sub-region 501, denoted by reference numeral 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, denoted by reference numeral 501-2, is located on the side of the second sub-region 502 closer to the second region (not shown). That is, the distance L18 between the edge of the first sub-region 501, denoted by reference numeral 501-2, away from the display area 101 and the display area 101 is less than the distance L19 between the edge of the first sub-region 501, denoted by reference numeral 501-1, away from the display area 101 and the display area 101.

[0117] The display substrate provided in this embodiment has signal line groups extending upwards. First, the extension direction changes in the second sub-region, tilting towards the display area. That is, the second sub-region begins to shrink inwards towards the display area compared to the first sub-region which is far from the second region. It can also realize that the first sub-region closer to the second region shrinks inwards towards the display area compared to the first sub-region farther from the second region. The wiring space on the side of the first sub-region closer to the second region that is far from the display area is increased, which is beneficial for setting up other structures.

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

[0119] It should be noted that, Figure 4 for Figure 3 Cross-sectional view along the middle BB'. (See diagram below.) Figure 4 As shown, the display substrate also includes a first insulating layer 11 located between the first 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 (TFT), which comprises an active layer, a gate, a source, and a drain. A first signal line is disposed on the same layer as the gate, and a second signal line is disposed on the same layer as the source and drain, for example. The TFT can be, for example, a bottom-gate structure, meaning the active layer is located on the side of the gate facing away from the first substrate. Figure 4 In the first insulating layer 11, a buffer layer is 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, i.e., the active layer is located between the gate and the first substrate. Figure 4 In the first insulating layer 11, there are: 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. The second insulating layer 12 includes an interlayer insulating layer located between the gate and the source and drain.

[0121] In some embodiments, such as Figure 2As shown, the number of signal lines 201 included in the second sub-region 502 is less than that of the first sub-region 501 connected to the second sub-region 502 on the side away from the second sub-region (not shown). Figure 2 The first sub-region 501 (labeled 501-1 in the attached figure) includes the number of signal lines 201.

[0122] In specific implementation, such as Figure 2 As shown, in the first sub-region 501 (reference numeral 501-1), some signal lines 201, after being electrically connected to the scan line 6, no longer extend upwards. Therefore, the number of signal lines 201 in the first sub-region 501 (reference numeral 501-2) is less than the number of signal lines 201 included in the second sub-region 502. Correspondingly, the number of signal lines 201 in the first sub-region 501 (reference numeral 501-2) is less than the number of signal lines 201 in the first sub-region 501 (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 (reference numeral 501-1). The signal lines 201 in the second sub-region 502 are tilted towards the display area 101 side, which does not cause an increase in the width of the second peripheral area where the second sub-region is located in the first direction. Correspondingly, the wiring space required for the first sub-region 501 (reference numeral 501-2) connected to the second sub-region 502 is also less than that required for the first sub-region 501 (reference numeral 501-1). After the signal line of the second sub-region 502 is tilted towards the display area, the first sub-region 501 (reference numeral 501-2) is shrunken inward towards the display area relative to the first sub-region 501 (reference numeral 501-1). The wiring space on the side of the first sub-region 501 (reference numeral 501-2) away from the display area 1010 is increased, which is beneficial for setting up other structures.

[0123] In some embodiments, such as 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 (i.e., the first sub-region 501 denoted as 501-2) that is connected to the second sub-region 502 on the side close to the second sub-region 502.

[0124] It should be noted that, Figure 2 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 (i.e., the first sub-region 501 denoted as 501-2) that is connected to the second sub-region 502 on the side close to the second sub-region 502, for example. That is, in the first peripheral area 102 corresponding to the second sub-region 502, no signal lines 201 are 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 denoted as 501-2.

[0125] Of course, in specific implementation, it can also be like this 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 sub-region 4. That is, in the first peripheral area 102 corresponding to the second sub-region 502, there are signal lines 201 electrically connected to the scan line 6, and the second sub-region 502 including the signal lines 201 does not need to extend to the first sub-region 501 marked 501-2 in the attached figure. Figure 5 The example given is that the first signal line 2011 closest to the display area 101 in the second sub-region 502 is electrically connected to the scan line 6 in the corresponding area of ​​the second sub-region 502. That is, the difference between the number of signal lines 201 in the second sub-region 502 and the number of signal lines 201 in the first sub-region 501 (labeled 501-2) is 1.

[0126] In some embodiments, such as Figure 3 As shown, in the first sub-region 501 and the second sub-region 502, the signal line group 2 includes multiple sub-groups 9, at least some of which include a first signal line 2011 and a second signal line 2012 having an overlapping region in the orthographic projection of the first substrate 1; in the first sub-region 501 and the second sub-region 502, the line width L4 of the multiple sub-groups 9 is equal, and the spacing L5 between any two adjacent sub-groups 9 is equal. That is, a first signal line 2011 and a second signal line 2012 having an overlapping region in the orthographic projection of the first substrate 1 constitute a sub-group 9.

[0127] In specific implementation, such as Figure 2 , Figure 5 As shown, the number of subgroups 9 included in the second subregion 502 is less than the number of subregions 501 connected to the second subregion 502 on the side away from the second region (not shown). Figure 2 The number of subgroups 9 included in the first sub-region 501 (reference numeral 501-1) is less than the number of subgroups 9 included in the first sub-region 501 (reference numeral 501-2) that connects to the second sub-region 502 on the side closer to the second region. Figure 2 The first subregion 501 (labeled 501-1 in the attached figure) includes the number of subgroups 9.

[0128] In specific implementation, such as 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 (i.e., the first sub-region 501 denoted as 501-2) connected to the second sub-region 502 on the side close to the second region, the number of subgroups 9 included in the second sub-region 502 is equal to the number of subgroups 9 included in the first sub-region 501 (i.e., the first sub-region 501 denoted as 501-2) connected to the second sub-region 502 on the side close to the second region.

[0129] In specific implementation, such as 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 (i.e., the first sub-region 501 denoted as 501-2) connected to the second sub-region 502 on the side closer to the second region 4, and when 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 (i.e., the first sub-region 501 denoted as 501-2) connected to the second sub-region 502 on the side closer to the second region 4 is less than or equal to 2, the number of subgroups 9 included in the second sub-region 502 is equal to the number of subgroups 9 included in the first sub-region 501 (i.e., the first sub-region 501 denoted as 501-2) connected to the second sub-region 502 on the side closer to the second region 4.

[0130] In 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 the side close to the second sub-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 the side close to the second sub-region is greater than 2, the number of subgroups included in the second sub-region is greater than the number of subgroups included in the first sub-region connected to the second sub-region on the side close to the second sub-region.

[0131] In some embodiments, such as Figure 3 As shown, in the first sub-region 501 and the second sub-region 502, the projections of multiple first signal lines 2011 onto the first substrate 1 and the projections of multiple second signal lines 2012 onto 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 subgroup 9.

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

[0134] Of course, in specific implementations, the linewidths of the first signal line and the second signal line can be unequal, with overlapping areas between the orthographic projections of the first signal line and the second signal line onto the first substrate. The orthographic projection of the first signal line onto the first substrate may fall within the orthographic projection of the second signal line onto the first substrate, or vice versa. The linewidth of a subgroup is the wider of the two signal lines, and the spacing between adjacent subgroups is the spacing between the wider signal lines.

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

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

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

[0138] In specific implementation, such as Figure 2 , Figure 5 As shown, when the number of signal lines 201 in the first sub-region far 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 subgroup is equal and the spacing L5 between two adjacent subgroups is equal, L26 is greater than L27.

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

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

[0141] L2≥L1-L3×cos a1.

[0142] It should be noted that, Figure 2 , Figure 5 The example given is L2 = L1 - L3 × cos a1. In practical implementation, such as... 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 denoted as 501-2) connected to the second subregion 502 on the side closer to the second subregion, 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 the side closer to the second subregion, L2 > L1 - L3 × cos a1.

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

[0144] In some embodiments, among the two first sub-regions connected to the second sub-region, the first sub-region farther from the second region includes m subgroups, and the first sub-region closer to the second region includes n subgroups, 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 the following:

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

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

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

[0149] In practical implementation, to avoid the signal lines included in the signal line group affecting the electrostatic unit, L2-L6 is greater than 2 micrometers. Preferably, for example, L2-L6 is greater than 3 micrometers.

[0150] In specific implementations, if the width of the first peripheral region in the first direction is 0.9 mm, typically L6 is approximately 90 micrometers, and correspondingly, L2 is greater than 92 micrometers, preferably greater than 93 micrometers. In some embodiments, L2 is 140 micrometers and L1 is 245 micrometers.

[0151] In a specific implementation, the electrostatic unit includes a plurality of first sub-units and second sub-units arranged along a second direction; in the direction from the first region to the second region, 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 scan line, and a 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; both the first sub-units and the second sub-units include, for example, thin-film transistors.

[0152] In some embodiments, such as Figure 2 , Figure 3 As shown, the multiple signal lines 201 included in the second sub-region 502 have equal lengths L3 in their extension directions.

[0153] In some embodiments, such as Figure 2 As shown, the edge at the junction of the second sub-region 502 and the first sub-region 501 extends along the fourth direction X2. The fourth direction X2 is the direction in which the display area 101 points to the side of the first peripheral area 1021 corresponding to the second sub-region 502. Figure 2 The angle a2 between the first 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, such as Figure 2 As shown, a1 is 45° and a2 is 23°.

[0156] In practice, when L2 is 140 micrometers, L1 is 245 micrometers, and a1 is 45°, L3 is approximately 148 micrometers.

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

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

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

[0160] like Figure 3 As shown, in the first direction X, the maximum width L20 of the first portion 801 is less than the maximum width L22 of the second portion 802; the second portion 802 includes: a first sublayer 8-1, and a second sublayer 8-2 located on the side of the first sublayer 8-1 facing 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 of the display substrate further includes a pixel electrode located on the side of the thin film transistor away from the first substrate, and the display substrate further includes a common electrode disposed over its entire surface; the common electrode may be disposed between the pixel electrode and the source / drain electrode, or it may be disposed 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 a display substrate is used in a liquid crystal display panel, the liquid crystal display panel also includes a counter substrate disposed opposite to the display substrate. An encapsulating adhesive needs to be applied between the display substrate and the counter substrate in a peripheral area. This encapsulating adhesive typically includes supporting silicon (Si) balls. In related technologies, the overlapping wiring area of ​​signal line groups does not include the area recessed towards the display area; that is, the wiring space on the side of the signal line group away from the display area is smaller, 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 two layers of signal lines overlap. This means that the thickness uniformity of the display substrate corresponding to the supporting silicon (Si) balls is poor, which can easily lead to a yellowish tint on the display panel screen.

[0163] The display substrate provided in this embodiment has a signal line group that begins to shrink inward from the display area from the second sub-region. The wiring space in the second sub-region and the side of the first sub-region closest to the second region away from the display area is increased. This allows for an increase in the width of the third signal line in the second sub-region and the side of the first sub-region closest to the second region away from the display area, providing sufficient space for double-layer wiring (including both the first and second sub-layers). This improves the thickness uniformity of the display substrate in the first peripheral region. Therefore, when the display substrate is used in a liquid crystal display panel, it can alleviate or even avoid the problem of a yellowish screen due to poor thickness uniformity of the display substrate corresponding to the supporting silicon balls, thus improving the display effect. Furthermore, the increased width of the second portion of the third signal line also helps to increase the resistance of the third signal line, thereby reducing the voltage drop of the third signal line.

[0164] In some embodiments, such as 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 lines included in the second sub-region 502. That is, the edge of the second portion adjacent to the second sub-region extends in a third direction.

[0165] In some embodiments, such as Figure 3 As shown, in the first peripheral area, the spacing between the second part 802 and the different sub-regions 5 of the signal line group 2 is approximately equal.

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

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

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

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

[0170] In some embodiments, such as Figure 3 As shown, the pattern of the first sublayer 8-1 projected onto the first substrate 1 is a grid. That is, the first sublayer 8-1 includes a plurality of first opening regions 13.

[0171] It should be noted that when the display substrate is used in a liquid crystal display panel, the encapsulating adhesive is usually a UV-curable adhesive, meaning that it needs to be irradiated with ultraviolet light after application. The pattern of the first sublayer projected onto the first substrate is a grid, which helps to improve the transmittance of ultraviolet light and increase the curing yield of the UV-curable adhesive.

[0172] In some embodiments, such as Figure 3 , Figure 4 As shown, the orthographic projection of the second sublayer 8-2 onto the first substrate 1 falls within the orthographic projection of the first sublayer 8-1 onto the first substrate.

[0173] In specific implementation, such as Figure 3 , Figure 4 As shown, the orthographic projection of the second sublayer 8-2 onto the first substrate 1 falls within the orthographic projection of the grid pattern of the first sublayer 8-1 onto the first substrate. Figure 3 , Figure 4 As shown, the orthographic projection of the second sublayer 8-2 onto the first substrate 1 and the orthographic projection of the first opening region 13 onto the first substrate do not overlap. This avoids the second sublayer affecting the transmittance of ultraviolet light.

[0174] Alternatively, in the second part, the orthographic projection of the second sublayer onto the first substrate may coincide with the orthographic projection of the grid pattern of the first sublayer onto the first substrate.

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

[0176] In some embodiments, such as Figure 3 As shown, the first part 801 only includes the first sublayer 8-1.

[0177] In some embodiments, such as 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 a first direction X; the extension line of the first edge 1011 is located on the 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 point b1 of the signal line 201 closest to the display area 101 in the second sub-region 502 and the first edge 1011 of the first sub-region 501 far away from the second region 4; 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 embodiments of this disclosure corresponds to the area where the display substrate is used to display images when applied to a display product, and the peripheral area involved in the embodiments of this disclosure corresponds to the area where image display is not required.

[0180] Alternatively, in some embodiments, such as Figure 8 As shown, the first region 3 includes two second sub-regions 502, and the reference numerals for the two second sub-regions 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 region 3 away from the second region 4.

[0181] In the second direction Y, in the second sub-region 502 (i.e., the second sub-region 502 with reference numerals 502-1) away from the second region 4, there is a fourth distance L9 between the connection point b4 of the signal line 201 closest to the display area 101 and the first sub-region 501 (i.e., the first sub-region 501 with reference numerals 501-1) away from the second region 4 and the first edge 1011; in the second direction Y, in the second sub-region 502 (i.e., the second sub-region 502 with reference numerals 502-2) close to the second region, there is a fifth distance L10 between the connection point b5 of the signal line 201 closest to the display area 101 and the first sub-region 501 (i.e., the first sub-region 501 with reference numerals 501-2) away from the second region 4 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 rectangular, and the sides of the rectangle are the edges of the display area. One pair of edges of the display area extends along the first direction X, and the other pair of edges extends along the second direction Y. The first edge extending along the first direction X of the display area is the boundary between the display area and the second peripheral area.

[0183] The first area includes two second sub-areas, meaning the signal line group is recessed twice inwards towards the display area within the first area.

[0184] In practical implementation, the first area can also include more second sub-areas, meaning the signal line group is recessed inwards towards the display area multiple times within the first area. It should be noted that the number of second sub-areas included in the first area, i.e., the number of times the signal line group is recessed towards the display area within the first area, can be specifically set based on the number of signal lines included in the signal line group and the size of the first peripheral area. The key is that as long as there is sufficient wiring space in the direction of signal line group extension, even after the number of signal lines is reduced, L2 meets the requirements after the signal line group is recessed.

[0185] In the display substrate provided in this embodiment, when the first region includes two second sub-regions, L9 is less than L7 compared to the case where the first region includes one second sub-region. Correspondingly, when the first region includes two second sub-regions, the length of the first part of the third signal line in the second direction is less than the length of the first part of the third signal line in the second direction when the first region includes one second sub-region. That is, when the first region includes two second sub-regions, the area occupied by the first part of the single-layer third signal line is smaller, 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, such as Figure 7 , Figure 9 As shown, the first region 3 also includes a third sub-region 503, and the second region 4 includes a fourth sub-region 504 connected to the third sub-region 503; the third sub-region 503 is connected to the first sub-region 501 closest to the second region 4 (i.e., the first sub-region 501 denoted by 501-2 in the attached figure).

[0187] The signal line 201 in the fourth sub-region 504 extends along the second direction Y, and at least a portion of the signal line 201 in the third sub-region 503 includes a portion extending along the fifth direction X3. The angle α3 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, Figure 9 for Figure 7 A magnified view of region C in the middle.

[0189] It should be noted that after the signal line group passes through the first sub-region near the second region, it continues to extend upward. 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. It is not necessary to increase the width of the second peripheral region in the first direction to achieve multiple first signal lines and multiple second signal lines alternately arranged in the second region within the fourth sub-region included in the second region. This avoids signal line overlap causing an increase in capacitance and affecting sub-pixel charging.

[0190] The display substrate provided in this embodiment has a signal line group that extends to the third sub-region and changes its extension direction. The signal line closest to the display area extends along the fifth direction and bends towards the display area, so that multiple signal lines have enough space to be arranged alternately in the fourth sub-region, avoiding signal line overlap that would increase capacitance and affect sub-pixel charging.

[0191] In some embodiments, such as 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 (i.e., the first sub-region 501 denoted as 501-2 in the attached figure) which is closest to the second region 4.

[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 (i.e., the first sub-region 501 denoted as 501-2 in the attached figure) which is closest to the second region 4.

[0193] In some embodiments, such as 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 The example given is that the number of signal lines 201 in the fourth sub-region 504 is equal to the number of signal lines 201 in the third sub-region 503. In the first peripheral region 102 corresponding to the third sub-region 503, no signal lines 201 are electrically connected to the scan line 6, and all signal lines 201 in the third sub-region 503 extend upwards to the fourth sub-region 504.

[0195] Of course, in specific implementation, the number of signal lines included in the fourth sub-region can be less 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 are signal lines electrically connected to the scan lines, and the signal lines included in the third sub-region do not need to extend to the fourth sub-region.

[0196] Because in the fourth sub-region, the first signal line and the second signal line are alternately arranged along the first direction, in some embodiments, such as... Figure 7 As shown, the minimum width L28 of the first sub-region 501 (i.e., the first sub-region 501 denoted as 501-2 in the attached figure) closest to the second region 4 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, such as Figure 7 As shown, the signal line 201 in the first sub-region 501 (i.e., the first sub-region 501 denoted as 501-2 in the attached figure) that is connected to the third sub-region 503, which is far away from the display area 101, and the signal line 201 in the fourth sub-region 504 that is far away from the display area 101 are on the same straight line.

[0198] That is, the signal line furthest from the display area in the signal line group does not change its extension direction and position after passing through the third and fourth sub-regions. In other words, the signal line furthest from the display area in the fourth sub-region does not need to be recessed, providing sufficient wiring space for the first and second signal lines to be arranged alternately along the first direction.

[0199] In some embodiments, such as Figure 7 As shown, in the first direction X, the signal line 201 closest to the display area 101 in the first sub-region 501 (i.e., the first sub-region 501 denoted as 501-2 in the attached figure) and the connection point with the third sub-region 503 have a sixth distance L11 to the display area 101; the signal line 201 closest to the display area 101 in the fourth sub-region 504 has a seventh distance L12 to the display area 101; and the length of the signal line 201 closest to the display area 101 in the third sub-region 503 in its extension direction is L13.

[0200] L11, L12, and L13 satisfy:

[0201] L12 <L11;

[0202] L12≥L11-L13×cos a3.

[0203] It should be noted that, Figure 7 The example given is L12 = L11 - L13 × cos a3. In practical implementation, such as... 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 practical implementation, when the width of the second peripheral area in the first direction is determined, and the number, width, and spacing of the signal lines included in the signal line group 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, such as Figure 7 As shown, in the first sub-region 501 and the third sub-region 503, the signal line group 2 includes multiple sub-groups 9;

[0206] like Figure 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 subgroups, 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 here k represents the number of subgroups included in the first subregion closest to the second region. As mentioned earlier, "the first subregion far from the second region includes m subgroups". When the first subregion far from the second region is the same as the first subregion closest to the second region, k = m.

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

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

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

[0214] In practical implementation, to avoid the signal lines included in the signal line group affecting the electrostatic unit, L12-L6 is greater than 2 micrometers. Preferably, for example, L12-L6 is greater than 3 micrometers.

[0215] In specific implementations, if the width of the first peripheral region in the first direction is 0.9 mm, then typically L6 is approximately 90 micrometers, and correspondingly, L12 is greater than 92 micrometers, preferably greater than 93 micrometers. In some embodiments, L12 is 285 micrometers.

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

[0217] In some embodiments, such as Figure 7 As shown, the edge at the junction of the third sub-region 503 and the first sub-region 501 (i.e., the first sub-region 501 marked as 501-2 in the attached figure) extends along the ninth direction X4. The angle α4 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 at the junction of the third sub-region 503 and the fourth sub-region 504 extends along the sixth direction X5. The angle α5 between the sixth direction X5 and the direction of the first peripheral area 1021 corresponding to the second sub-region 502 pointing to the side of the display area 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 and fourth sub-regions.

[0222] In some embodiments, such as 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 a first direction X; the extension line of the first edge 1011 is located on the 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 point b2 of the signal line 201 closest to the display area 101 in the third sub-region 503 and the first sub-region 501 (i.e., the first sub-region 501 marked as 501-2 in the attached 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] Alternatively, in some embodiments, such as Figure 8 As shown, the first region 3 includes two second sub-regions 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 the side of the first region 3 away from the second region 4;

[0225] In the second direction Y, there is an eighth distance L17 between the connection point of the signal line 201 closest to the display area 101 in the third sub-region 503 and the first sub-region 501 (i.e., the first sub-region 501 marked as 501-3 in the attached 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, such as Figure 9 As shown, the second part 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 near the edge of the signal line group is parallel to the extension direction of the signal line furthest from the display area in the third and fourth sub-regions.

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

[0229] The display substrate provided in this embodiment has a signal line group that begins to shrink towards the display area from the eighth sub-region of the second region. The width of the second part adjacent to the eighth sub-region and the ninth region is further increased, which is more conducive to increasing the resistance of the third signal line and thus alleviating the voltage drop of the third signal line.

[0230] In some embodiments, such as Figure 1As shown, the peripheral area 102 also 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 An enlarged schematic diagram of region E in the middle is shown below. Figure 11 As shown, in the third peripheral area 104, the extension direction 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 this edge is deflected towards the display area. That is, in the third peripheral area 104, the second portion 802 is recessed towards the display area 101, thereby leaving space on the side of the second portion 802 away from the display area 101 to set other structures, such as... Figure 11 The dummy structure 21 in the middle prevents static electricity accumulation.

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

[0232] The third region 10 includes the fifth sub-region 505 and the 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. The extension direction of at least a portion of the signal line 201 in the sixth sub-region 506 intersects both the second direction Y and the first direction X.

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

[0235] In some embodiments, such as Figure 1 As shown, the third region 10 also includes a tenth sub-region 510; the tenth sub-region 510 is connected to the signal terminals (not shown) of the sixth sub-region 506 and the bonding region 1031; in the tenth sub-region 510, a plurality of first signal lines 2011 and a 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 practice, the signal line group extends from the bonding area of ​​the second peripheral region. Before reaching the first peripheral region, the number of signal lines included in the signal line group remains unchanged in different sub-regions. In the second peripheral region, the signal line group has ample wiring space. Therefore, in the part electrically connected to the signal terminal, i.e., the tenth sub-region, the signal lines included in the signal line group can be alternately routed, i.e., the first signal line and the second signal line are arranged alternately, avoiding signal line overlap that would increase capacitance and affect sub-pixel charging. When the signal line group extends to the first peripheral region, the wiring space in the first region, where the total number of signal lines remains unchanged, becomes smaller. Therefore, the signal line group adopts overlapping wiring in the first region. In the second peripheral region, the fifth sub-region where the signal line group connects to the first region also adopts overlapping wiring. That is, the signal line group alternately routes along the first direction in the tenth sub-region, changes its extension direction in the sixth sub-region, and changes its extension direction again in the fifth sub-region, switching to overlapping wiring. Compared to directly changing from alternating wiring to overlapping wiring at the boundary between the second and first peripheral regions, this is beneficial for making reasonable use of the space in the second peripheral region and reducing wiring difficulty.

[0237] In specific implementation, the extension direction of any signal line in the fifth sub-region of the signal line group is on the same straight line as the extension direction of the signal line in the first sub-region connected to the fifth sub-region. That is, the extension direction of the signal line group remains unchanged as it passes through the fifth sub-region and the first sub-region connected to the fifth sub-region.

[0238] Alternatively, in some embodiments, such as Figure 12 , Figure 13 As shown, in the second peripheral area 103, the third area 10 also includes: a seventh sub-area 507 connected to the sixth sub-area 506; the seventh sub-area 507 connects the sixth sub-area 506 and the tenth sub-area 510;

[0239] The signal line 201 in the seventh sub-region 507 extends in a direction that intersects with the second direction Y, and the signal line 201 in the seventh sub-region 507 extends in a direction that intersects with the signal line 201 in the sixth sub-region 506.

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

[0241] In the second peripheral area, the signal line group extends along the second direction in the tenth sub-region, changes its extension direction once in the seventh sub-region, changes its extension direction again in the sixth sub-region, and then returns to the second direction in the fifth sub-region, becoming an overlapping wiring configuration. In actual implementation, the number of times the extension direction needs to be changed between the tenth and fifth sub-regions can be selected based on the number of signal lines and the actual wiring space of the signal line group.

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

[0243] In some embodiments, such as Figure 12 As shown, the edge at 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 of the display area 101 pointing to the first peripheral area 1021 is greater than 0° and less than 90°.

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

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

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

[0247] In some embodiments, such as Figure 12 As shown, the distance from the signal line 201 closest to the display area 101 in the fifth sub-region 505 to the display area 101 is L30; in the second direction Y, in the sixth sub-region 506, the distance from the connection point b6 between 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 the connection point b7 to b6 between the signal line 201 closest to the display area and the seventh sub-region 507 is L32; in the sixth sub-region 506, the distance from the connection point b8 between the signal line 201 furthest 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 micrometers and less than or equal to 690 micrometers, L31 is approximately 200 micrometers, and L32 is approximately 230 micrometers; if the display substrate includes electrostatic units, then L30 is greater than or equal to 92 micrometers, preferably L30 is greater than 93 micrometers.

[0248] In some embodiments, such as Figure 1 As shown, the display substrate includes two signal line groups 2, which correspond to two first peripheral regions 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, such as Figure 1 As shown, the display substrate also includes a ground level signal line 14, located on the side of the third signal line 8 away from the display area 101.

[0251] In specific implementation, such as Figure 1 As shown, both the ground level signal line 14 and the third signal line 8 are electrically connected to the bonding end (not shown) of the bonding area 1031; the display substrate also includes a third peripheral area 104 located on the side of the display area 101 opposite to the second peripheral area 103; the third signal line 8 is led out from the bonding 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 bonding area 1031 of the second peripheral area 103; the ground level signal line 14 is led out from the bonding 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 bonding area 1031 of the second peripheral area 103.

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

[0253] The display substrate 15 provided in the embodiments of this disclosure;

[0254] The opposing substrate 16 is disposed opposite to the display substrate 15;

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

[0256] In some embodiments, such as Figure 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] Multiple support portions 18 are located between the display substrate 15 and the opposing substrate 16; the orthographic projection of the support portions on the first substrate 1 overlaps with the orthographic projection of the second portion 802 on the first substrate 1.

[0259] In specific implementation, such as Figure 15 As shown, at least a portion of the support portion 18 overlaps with the orthographic projection of the second sublayer 8-2 and the first sublayer 8-1 included in the second portion 802 on the first substrate 1.

[0260] The display device provided in this embodiment has an overlapping projection of the support portion onto the first substrate and the second portion onto the first substrate. Since the second portion of the signal line has double-layer wiring, including the first sub-layer and the second sub-layer, the thickness uniformity of the display substrate in the peripheral area is better. This can alleviate or even avoid the problem of the display device screen being yellowish due to poor thickness uniformity of the display substrate corresponding to the support portion, thereby improving the display effect.

[0261] In specific implementation, such as Figure 15 As shown, an encapsulant 19 and a plurality of support portions 18 are included between the display substrate 15 and the opposing substrate 16. The support portions 18 are, for example, silicon balls included in the encapsulant 19.

[0262] In some embodiments, such as Figure 16 As shown, the display substrate includes a second peripheral region 103; the second peripheral region includes a bonding region 1031; the display substrate also includes a plurality of signal terminals (not shown) located on one side of the first substrate 1 in the bonding region 1031; the signal line group 2 is electrically connected to a portion of the plurality of signal terminals;

[0263] The display device also includes a driver chip IC; the driver chip IC is bonded to multiple signal terminals in the bonding area 1031.

[0264] In some embodiments, the opposing substrate includes: a second substrate, a black matrix and a color resist on the side of the second substrate facing the liquid crystal layer; the black matrix has an opening region corresponding one-to-one with a sub-pixel unit of the display substrate, and the color resist is located within the opening region; spacers are located on the side of the black matrix facing the liquid crystal layer. The color resist corresponds one-to-one with the sub-pixel region, and the orthographic projection of the color resist onto the array substrate falls within the sub-pixel region. The sub-pixel unit includes a red sub-pixel, a blue sub-pixel, and a green sub-pixel. Correspondingly, the color resist includes a red color resist corresponding to the red sub-pixel, a blue color resist corresponding to the blue sub-pixel, and a green color resist corresponding to the green sub-pixel.

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

[0266] In practical implementation, a side-lit backlight module may include LED strips, stacked reflective sheets, light guide plates, diffusers, prism assemblies, etc., with the LED strips located on one side of the thickness direction of the light guide plate. A direct-lit backlight module may include a matrix light source, a reflective sheet, diffuser plate, and brightness enhancement film stacked on the light-emitting side of the matrix light source, with the reflective sheet including openings directly opposite the positions of the LEDs in the matrix light source. The LEDs in the LED strips and the LEDs in the matrix light source can be light-emitting diodes (LEDs), such as miniature LEDs (Mini LEDs, Micro LEDs, etc.). Submillimeter-scale or even micrometer-scale miniature LEDs, like organic light-emitting diodes (OLEDs), are self-emissive devices. Like OLEDs, they possess a series of advantages such as high brightness, ultra-low latency, and ultra-wide viewing angles. Furthermore, because inorganic LEDs emit light based on more stable and lower-resistance metal semiconductors, they have advantages over organic LEDs, such as lower power consumption, greater resistance to high and low temperatures, and longer lifespan. Furthermore, when micro LEDs are used as backlights, more precise dynamic backlighting effects can be achieved. This not only effectively improves screen brightness and contrast but also solves the glare problem caused by traditional dynamic backlighting between bright and dark areas of the screen, thus optimizing the visual experience.

[0267] The display device provided in this disclosure includes any product or component with a display function, such as a mobile phone, tablet computer, television, monitor, laptop computer, digital photo frame, or navigator. Other essential components of this display device are understood by those skilled in the art and will not be described in detail here, nor should they be construed as limiting this disclosure. Implementation of this display device can refer to the embodiments of the display panel described above; repeated details will not be repeated.

[0268] In summary, the display substrate, display panel, and display device provided in this disclosure, in a first region with a large number of signal lines, have overlapping projections of multiple first signal lines onto the first substrate and multiple second signal lines onto the first substrate. That is, the signal lines in the signal line group overlap and are routed in the first region, saving wiring space and preventing the first peripheral area from being too large in the first direction, which is detrimental to achieving a narrow bezel. In a second region with a smaller number of signal lines, multiple first signal lines and multiple second signal lines are arranged alternately along the second direction. That is, the signal line group has alternating wiring of multiple first signal lines and multiple second signal lines in the second region. Due to the reduced number of signal lines, it is not necessary to increase the width of the second peripheral area in the first direction to achieve the alternating arrangement of multiple first signal lines and multiple second signal lines in the second region, avoiding complete overlap of signal lines that would increase capacitance and affect sub-pixel charging. 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 region to the second region, the number of signal lines in the multiple sub-regions included in the first region is not exactly the same. The number of signal lines in at least one sub-region close to the second region is less than the number of signal lines in at least one sub-region far from the second region. The wiring space required for at least one sub-region close to the second region is less than the wiring space required for at least one sub-region far from the second region. Therefore, the distance L18 between the edge of at least one sub-region far from the display area and the display area can be set to be less than the distance L19 between the edge of at least one sub-region far from the display area and the display area in the remaining sub-regions. That is, one sub-region is recessed towards the display area relative to another sub-region, and the wiring space on the side of the sub-region far from the display area is increased, which is beneficial for setting up other structures.

[0269] Although preferred embodiments of the invention have been described, those skilled in the art, upon learning the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including both the preferred embodiments and all changes and modifications falling within the scope of the invention.

[0270] Obviously, those skilled in the art can make various modifications and variations to this disclosure without departing from its spirit and scope. Therefore, if such modifications and variations fall within the scope of the claims of this disclosure and their equivalents, this disclosure is also intended to include such modifications and variations.
