[0084] In one embodiment, the third conductive layer and the fourth conductive layer each include a plurality of grid-like structures, and the orthographic projection of each light-emitting structure on the substrate falls within the orthographic projection of a grid-like structure on the substrate.

[0085] In one embodiment, the shielding line 20 may be connected to a constant electrical signal, or the signal of the shielding line 20 and the signal of the touch signal line 10 may both be square wave signals.

[0086] In one embodiment, Figure 2B As shown, the display substrate includes a display area 110 and a non-display area 120, and the non-display area 120 is located on at least one side of the display area 110. In the embodiment shown in FIG. 2 , the non-display area 120 surrounds the display area 110, and the non-display area 120 includes a non-display sub-area 121, a non-display sub-area 122, a non-display sub-area 123, and a non-display sub-area 124, wherein the non-display sub-area 121 is opposite to the non-display sub-area 122, and the non-display sub-area 123 is opposite to the non-display sub-area 124. The direction from the display area 110 to the non-display sub-area 121 is the first direction Y.

[0087] In one embodiment, Figure 1 and Figure 2B As shown, the non-display sub-area 121 includes a transition area 1211, a bending area 1212 and a binding area 1213. The bending area 1212 is adjacent to the transition area 1211 and the binding area 1213, and the display area 110 is adjacent to the transition area 1211. After the display substrate is bent, the portion of the display substrate located in the bending area 1212 is bent, and the binding area 1213 is located on the side of the display area 110 away from the display surface.

[0088] In one embodiment, the display substrate includes a plurality of binding terminals located in the binding area 1213. The touch signal line 10, the shielding line 20 and other wirings are connected to the binding terminals, and the binding terminals can be bound to a FPC (Flexible Printed Circuit), so that the chip connected to the FPC can provide signals to the wirings.

[0089] In one embodiment, at least a portion of the first shielding segment 21 and the first section 11 are located in the transition area 1211 , and the second section 12 and the second shielding segment 22 are located in the transition area 1211 , the bending area 1212 and the binding area 1213 . Figure 1 In the illustrated embodiment, the first shielding segment 21 and the first section 11 are only located in the transition region 1211 .

[0090] In one embodiment, Figure 3As shown, at least part of the section of the touch signal line 10 located in the transition area 1211 includes a first touch signal part 102 and a second touch signal part 103 located on a side of the first touch signal part 102 away from the substrate; at least part of the section of the shielding line 20 located in the transition area 1211 includes a first shielding part 201 and a second shielding part 202 located on a side of the first shielding part 201 away from the substrate, the first touch signal part 102 and the first shielding part 201 are located on the third conductive layer 31 of the touch layer, and the second touch signal part 103 and the second shielding part 202 are located on the fourth conductive layer 32 of the touch layer. In this way, the resistance of the touch signal line 10 and the shielding line 20 is reduced.

[0091] In one embodiment, at least part of the section of the touch signal line 10 located in the binding area 1213 includes a first touch signal part and a second touch signal part located on a side of the first touch signal part away from the substrate; at least part of the section of the shielding line located in the binding area 1213 includes a first shielding part and a second shielding part located on a side of the first shielding part away from the substrate, the first touch signal part and the first shielding part are located on the third conductive layer of the touch layer, and the second touch signal part and the second shielding part are located on the fourth conductive layer of the touch layer. In this way, the resistance of the touch signal line 10 and the shielding line 20 is further reduced.

[0092] In one embodiment, Figure 1 and Figure 4 As shown, the first shielding segment 21 is located between two adjacent touch signal line groups 101, and in the same shielding line 20, two second shielding segments 22 are directly connected to the first shielding segment 21. Since the first shielding segment 21 is located between two adjacent touch signal line groups 101, the second shielding segment 22 can be directly connected to the first shielding segment 21, which can simplify the structure and preparation process of the shielding line 20.

[0093] In one embodiment, Figure 1 and Figure 5 As shown, the shielding line 20 also includes a third shielding segment 23 located in the binding area 1213, and the third shielding segment 23 is located between two adjacent touch signal line groups 101; in the same shielding line 20, two second shielding segments 22 are directly connected to the same third shielding segment 23. The third shielding segment 23 is connected to the binding terminal. In this way, both second shielding segments 22 are connected to the binding terminal through the third shielding segment 23, which helps to simplify the wiring complexity of the display substrate.

[0094] In one embodiment, Figure 1 and Figure 5As shown, the touch signal line 10 also includes a third section 15 located in the binding area 1213, and the third section 15 is connected to the binding terminal. The maximum distance between the third sections 15 of two adjacent touch signal line groups 101 is less than the maximum distance between the second sections 12 of two adjacent touch signal line groups 101. The third shielding section 23 is located between the third sections 15 of the two touch signal line groups. By setting the third shielding section 23 between the two third sections 15, signal crosstalk can be prevented in the third sections 15 located on both sides of the third shielding section 23.

[0095] In one embodiment, Figure 4 As shown, the second shielding segment 22 is located in a portion of the transition area 1211, and the width of a portion 2201 of the second shielding segment 22 extending along the first direction Y is greater than the width of a portion 2202 of the second shielding segment 22 extending along a second direction X intersecting the first direction Y. Such a configuration helps to reduce the width of the transition area 1211 in the first direction Y, thereby reducing the border width of the display substrate. Figure 4 In the illustrated embodiment, the second direction X is perpendicular to the first direction Y. In other embodiments, the angle between the second direction X and the first direction Y may be an acute angle.

[0096] In one embodiment, the touch signal line 10 is located in a portion of the transition area 1211, and the width of the portion of the touch signal line 10 extending along the first direction Y is greater than the width of the portion of the touch signal line 10 extending along the second direction X intersecting the first direction Y. Such a configuration helps to reduce the width of the transition area 1211 in the first direction Y, thereby reducing the border width of the display substrate.

[0097] In one embodiment, Figures 6 to 8 As shown, the first shielding segment 21 is located between two adjacent touch signal lines 10 of the same touch signal line group 101, and the shielding line 20 also includes a connecting segment 24, and the first shielding segment 21 is connected to the second shielding segment 22 through the connecting segment 24; the first shielding segment 21 is connected to the binding terminal. In this way, the second shielding segment 22 is connected to the first shielding segment 21 through the connecting segment 24, and the first shielding segment 21 can transmit the signal provided by the chip to the second shielding segment 22, and the second shielding segment 22 does not need to be connected to the binding terminal, which helps to reduce the number of binding terminals.

[0098] Further, such as Figure 6 and Figure 7 As shown, in the same shielding line 20, two second shielding segments 22 are connected, and the connecting segment 24 is connected to one second shielding segment 22. This helps to simplify the wiring complexity of the display substrate.

[0099] In one embodiment, Figure 8 and Fig. 9 As shown, the first shielding segment 21 is partially located between two adjacent second segments 12 of the same touch signal line group 101, and the second shielding segment 22 connected to the connecting segment 24 and the second segment 12 between the first shielding segment 21 include a first sub-segment 13, and the orthographic projection of the first sub-segment 13 on the substrate overlaps with the orthographic projection of the connecting segment 24 on the substrate; the first sub-segment 13 and the connecting segment 24 are located in different conductive layers. In this way, a short circuit between the connecting segment 24 and the first sub-segment 13 can be avoided.

[0100] In one embodiment, Figures 8 to 10 As shown, the connecting segment 24 is located in the fourth conductive layer 32, and the first sub-segment 13 is located in the third conductive layer 31. That is, the first sub-segment 13 only includes the first touch signal portion 102, and the connecting segment 24 only includes the second shielding portion 202. In other embodiments, the connecting segment 24 may be located in the third conductive layer, and the first sub-segment 13 may be located in the fourth conductive layer. The first insulating layer 247 is provided with a through hole 205, and the second segment 12 is located in the fourth conductive layer 32 and the portions located on both sides of the connecting segment 24 are electrically connected to the third conductive layer 31 through the through holes 205.

[0101] Furthermore, if Figure 6 As shown, the connecting section 24 is located in the transition zone 1211. In another embodiment, as Figure 7 As shown, the connecting segment 24 is located in the binding area 1213. In order to facilitate the bending of the display substrate in the bending area, the thickness of the bending area is relatively small, and the touch layer is generally hollowed out in the bending area, and the part of the touch signal line located in the bending area is arranged in the conductive layer of the pixel circuit layer. Therefore, when the connecting segment 24 and the first sub-segment 13 are arranged in the touch layer, the connecting segment 24 and the first sub-segment 13 are located in the binding area or the transition area.

[0102] In one embodiment, the first sub-segment 13 is located in the first conductive layer; the connecting segment 24 is located in the conductive layer of the touch layer. Such a configuration can make the distance between the first sub-segment 13 and the connecting segment 24 larger in the direction perpendicular to the substrate, reduce the signal interference of the connecting segment 24 on the touch signal line 10, and help improve the touch accuracy of the display substrate; and the first sub-segment 13 is located in the first conductive layer of the pixel circuit layer, so the first sub-segment 13 is formed simultaneously with the structure of the pixel circuit layer, which does not increase the process complexity of the display substrate.

[0103] Furthermore, if Fig.11 and Fig.12As shown, the first sub-segment 13 and the connecting segment 24 are located in the bending area 1212. Specifically, the first sub-segment 13 and the connecting segment 24 are located in the edge area of ​​the bending area 1212 close to the binding area 1213. Since the part of the touch signal line and the shielding line located in the bending area is arranged on the conductive layer of the pixel circuit layer, the first sub-segment 13 is arranged on the first conductive layer of the pixel circuit layer, which does not increase the complexity of the manufacturing process of the display substrate.

[0104] In one embodiment, Fig.12 As shown, the second section 12 also includes a second sub-section 14 located in the bending area 1212, and the second sub-section 14 is connected to the first sub-section 13; the second sub-section 14 is located in the second conductive layer 53. Since the distance between the first conductive layer and the touch layer is greater than the distance between the second conductive layer and the touch layer, the first sub-section 13 is arranged in the first conductive layer, so that in the direction perpendicular to the substrate, the distance between the first sub-section 13 and the connecting section 24 is larger, further reducing the signal interference of the connecting section 24 on the touch signal line 10; the second sub-section 14 is located in the second conductive layer of the pixel circuit layer, and the structure of the second sub-section 14 and the pixel circuit layer is formed at the same time, which will not increase the process complexity of the display substrate.

[0105] In one embodiment, Fig.12 As shown, the portion of the touch signal line 10 located in the bending area 1212 includes two second sub-segments 14, and the two ends of the first sub-segment 13 are respectively connected to the second sub-segments 14. The first sub-segment 13 of the touch signal line 10 located in the bending area 1212 is arranged on the side of the second sub-segment 14 facing the substrate, which helps to improve the interference of static electricity on the touch signal line 10.

[0106] In one embodiment, Fig.12 As shown, the connecting segment 24 is located in the fourth conductive layer 32 of the touch layer. In this way, the distance between the first sub-segment 13 and the connecting segment 24 can be increased in the direction perpendicular to the substrate, which can further reduce the signal interference of the connecting segment 24 on the touch signal line 10 and improve the touch accuracy of the display substrate.

[0107] In one embodiment, Fig.12 As shown, the first conductive layer of the pixel circuit layer includes a first sub-conductive layer 51 and a second sub-conductive layer 52 , some first sub-segments 13 are located in the first sub-conductive layer 51 , and other first sub-segments 13 are located in the second sub-conductive layer 52 .

[0108] In one embodiment, Fig.12As shown, the portion of the second shielding segment 22 located in the bending zone 1212 includes a third sub-segment 221 and a fourth sub-segment 222 , the third sub-segment 221 and the fourth sub-segment 222 are connected, the third sub-segment 221 is located in the first conductive layer, and the fourth sub-segment 222 is located in the second conductive layer 53 . Fig.12 In the illustrated embodiment, the third sub-section 221 is located in the first sub-conductive layer 51 of the first conductive layer. This arrangement helps to improve the interference of static electricity on the shielding wire 20.

[0109] In one embodiment, Fig.12 As shown, the portion of the second shielding segment 22 located in the bending area 1212 includes two fourth sub-segments 222 , and two ends of the third sub-segment 221 are respectively connected to the fourth sub-segment 222 .

[0110] In one embodiment, Fig.12 As shown, the portion of the first shielding segment 21 located in the bending zone 1212 includes a fifth sub-segment 211 and a sixth sub-segment 212 , the fifth sub-segment 211 and the sixth sub-segment 212 are connected, the fifth sub-segment 211 is located in the first conductive layer, and the sixth sub-segment 212 is located in the second conductive layer 53 . Fig.12 In the illustrated embodiment, the fifth sub-section 211 is located in the second sub-conductive layer 52 of the first conductive layer. This arrangement helps to improve the interference of static electricity on the shielding wire 20.

[0111] In one embodiment, Fig.12 As shown, the portion of the first shielding segment 21 located in the bending area 1212 includes two sixth sub-segments 212 , and both ends of the fifth sub-segment 211 are respectively connected to the sixth sub-segment 212 .

[0112] In one embodiment, Fig.12 As shown, two adjacent traces are located in the first conductive layer, wherein the portion of one trace located in the first conductive layer is located in the first sub-conductive layer 51, and the portion of the other trace located in the first conductive layer is located in the second sub-conductive layer 52. This can prevent the portions of adjacent traces located in the first conductive layer from short circuiting.

[0113] In one embodiment, Fig.12As shown, the connecting segment 24 sequentially connects the first sub-connecting segment 241, the second sub-connecting segment 242 and the third sub-connecting segment 243, and the orthographic projection of the second sub-connecting segment 242 on the substrate overlaps with the orthographic projection of the first sub-segment 13 on the substrate. The orthographic projection of the first sub-connecting segment 241 on the substrate falls within the orthographic projection of the first shielding segment 21 on the substrate, and the orthographic projection of the third sub-connecting segment 243 on the substrate falls within the orthographic projection of the second shielding segment 22 on the substrate. Since the signals of the first sub-connecting segment 241, the third sub-connecting segment 243, the first shielding segment 21 and the second shielding segment 22 are the same, there will be no interference between the first sub-connecting segment 241 and the first shielding segment 21, and there will be no interference between the third sub-connecting segment 243 and the second shielding segment 22.

[0114] In one embodiment, Fig.13 As shown, the display substrate further includes a ground signal line 40, and the ground signal line 40 includes a first ground signal segment 41 and a second ground signal segment 42. The first ground signal segment 41 and the second ground signal segment 42 are located between two second shielding segments 22 of the same shielding line 20, and are respectively adjacent to different second shielding segments 22. In this way, the first ground signal segment 41 and the second ground signal segment 42 can further reduce the interference of static charge and other signal lines on the touch signal line, which is more conducive to improving the touch accuracy of the display substrate.

[0115] In one embodiment, at least part of the ground signal line 40 in the section located in the binding area 1213 includes a first ground portion and a second ground portion located on a side of the first ground portion away from the substrate; the first ground portion is located on the third conductive layer of the touch layer, and the second ground portion is located on the fourth conductive layer of the touch layer. This helps to further reduce the resistance of the ground signal line 40.

[0116] In one embodiment, Fig.13 As shown, the ground signal line 40 also includes a third ground signal segment 43; the first ground signal segment 41 and the second ground signal segment 42 are respectively connected to the same third ground signal segment 43, and the third ground signal segment is connected to the binding terminal. This arrangement can simplify the routing complexity of the display substrate.

[0117] Furthermore, if Fig.13 As shown, the shielding line 20 includes a third shielding segment 23 located in the binding area 1213, and the third grounding signal segment 43 is adjacent to the third shielding segment 23. In this way, the third grounding signal segment can further improve the signal crosstalk with the touch signal lines located on both sides thereof.

[0118] Furthermore, if Fig.13As shown, the shielding line 20 includes two third shielding segments 23 , and the third ground signal segment 43 is located between the two third shielding segments 23 .

[0119] In one embodiment, Fig.14 As shown, the ground signal line 40 includes a first ground signal segment 41, a second ground signal segment 42, a fourth ground signal segment 44 and a fifth ground signal segment 45; the first ground signal segment 41 is connected to the second ground signal segment 42, the first ground signal segment 41 and the second ground signal segment 42 are located between the two second shielding segments 22 of the same shielding line 20, and are respectively adjacent to different second shielding segments 22; the fourth ground signal segment 44 is located on the same side of the at least two touch signal line groups. The fourth ground signal segment 44 can shield the interference of external static electricity and other signal lines on the touch signal line.

[0120] Furthermore, if Fig.14 As shown, the fourth ground signal segment 44 is connected to the first ground signal segment 41 through the fifth ground signal segment 45; the fourth ground signal segment 44 is connected to the binding terminal. In this way, the signals of the first ground signal segment 41, the second ground signal segment 42, the fourth ground signal segment 44 and the fifth ground signal segment 45 are the same, and there is no need to set a signal segment connecting the first ground signal segment and the second ground signal segment to the binding terminal, which helps to simplify the routing complexity.

[0121] Furthermore, if Fig.14 As shown, the ground signal line 40 further includes a sixth ground signal segment 46, and the sixth ground signal segment 46 and the fourth ground signal segment 44 are located on opposite sides of the at least two touch signal line groups 101. The sixth ground signal segment 46 can further improve the interference of the touch signal line. The sixth ground signal segment 46 can be electrically connected to the fourth ground signal segment 44. For example, the display substrate may include a shielding ring arranged at the periphery of the display area, and the sixth ground signal segment 46 and the fourth ground signal segment 44 are respectively a part of the shielding ring.

[0122] In one embodiment, Fig.15As shown, the second section 12 includes a first sub-section 13; the second shielding section 22 includes a third sub-section 221; the first shielding section 21 includes a fifth sub-section 211; the orthographic projection of the fifth grounding signal section 45 on the substrate overlaps with the orthographic projections of the first sub-section 13, the third sub-section 221 and the fifth sub-section 211 on the substrate; the fifth grounding signal section 45 and the first sub-section 13, the third sub-section 221 and the fifth sub-section 211 are respectively located in different conductive layers to avoid short circuit. The first insulating layer 247 is provided with a through hole 205; the second section 12, the first shielding section 21 and the second shielding section 22 are located in the fourth conductive layer 32 and on both sides of the connecting section 24 are electrically connected to the third conductive layer 31 through the through hole 205.

[0123] In one embodiment, the fifth ground signal segment 45 is located in the fourth conductive layer, and the first sub-segment 13, the third sub-segment 221 and the fifth sub-segment 211 are located in the third conductive layer; or the fifth ground signal segment 45 is located in the third conductive layer, and the first sub-segment 13, the third sub-segment 221 and the fifth sub-segment 211 are located in the fourth conductive layer.

[0124] Furthermore, if Fig.14 As shown, the fifth ground signal segment 45, the first sub-segment 13, the third sub-segment 221 and the fifth sub-segment 211 are located in the transition area 1211. In other embodiments, the fifth ground signal segment 45, the first sub-segment 13, the third sub-segment 221 and the fifth sub-segment 211 may be located in the binding area 1213. In order to facilitate the display substrate to bend in the bending area, the thickness of the bending area is relatively small, and the touch layer is generally hollowed out in the bending area. The part of the touch signal line located in the bending area is arranged on the conductive layer of the pixel circuit layer. Therefore, when the fifth ground signal segment 45, the first sub-segment 13, the third sub-segment 221 and the fifth sub-segment 211 are arranged in the touch layer, the fifth ground signal segment 45, the first sub-segment 13, the third sub-segment 221 and the fifth sub-segment 211 are located in the binding area or the transition area.

[0125] In one embodiment, the first sub-segment 13, the third sub-segment 221 and the fifth sub-segment 211 are located in the first conductive layer, and the fifth ground signal segment is located in the conductive layer of the touch layer. Such a configuration can make the distance between the fifth ground signal segment 45 and the first sub-segment 13, the third sub-segment 221 and the fifth sub-segment 211 larger in the direction perpendicular to the substrate, thereby reducing the signal interference of the fifth ground signal segment 45 on the touch signal line 10 and the shielding line, which helps to improve the touch accuracy of the display substrate; and the first sub-segment 13, the third sub-segment 221 and the fifth sub-segment 211 are located in the first conductive layer of the pixel circuit layer, then the first sub-segment 13, the third sub-segment 221 and the fifth sub-segment 211 are all formed simultaneously with the structure of the pixel circuit layer, which does not increase the process complexity of the display substrate.

[0126] Furthermore, if Fig.16 and Fig.17 As shown, the first sub-segment 13, the third sub-segment 221, the fifth sub-segment 211 and the fifth ground signal segment 45 are located in the bending area 1212. Specifically, the first sub-segment 13, the third sub-segment 221, the fifth sub-segment 211 and the fifth ground signal segment 45 are located in the edge area of ​​the bending area 1212 close to the binding area 1213. Since the part of the touch signal line, the ground signal line and the shielding line located in the bending area is arranged on the conductive layer of the pixel circuit layer, the first sub-segment 13, the third sub-segment 221 and the fifth sub-segment 211 are arranged on the first conductive layer of the pixel circuit layer, which will not increase the complexity of the manufacturing process of the display substrate. The connecting segment 24 can also be located in the bending area 1212, and the fifth ground signal segment 45 and the connecting segment are located in the edge area adjacent to the bending area 1212 and the binding area 1213.

[0127] Furthermore, if Fig.17 As shown, the fifth ground signal segment 45 is located in the fourth conductive layer 32. This arrangement can make the distance between the fifth ground signal segment 45 and the first sub-segment 13, the fourth sub-segment 222 of the second shielding segment 22 and the sixth sub-segment 212 of the first shielding segment 21 larger in the direction perpendicular to the substrate.

[0128] Furthermore, if Fig.17As shown, the fifth ground signal segment 45 includes a first sub-ground signal segment 451, a second sub-ground signal segment 452 and a third sub-ground signal segment 453 connected in sequence, and the orthographic projection of the second sub-ground signal segment 452 on the substrate overlaps with the orthographic projections of the first sub-segment 13, the fourth sub-segment 222 and the sixth sub-segment 212 on the substrate; the orthographic projection of the first sub-ground signal segment 451 on the substrate falls within the orthographic projection of the fourth ground signal segment 44 on the substrate, and the orthographic projection of the third sub-ground signal segment 453 on the substrate falls within the orthographic projection of the first ground signal segment 41 on the substrate. Since the signals of the first sub-ground signal segment 451, the fourth ground signal segment 44, the third sub-ground signal segment 453 and the first ground signal segment 41 are the same, there will be no interference between the first sub-ground signal segment 451 and the fourth ground signal segment 44, and there will be no interference between the third sub-ground signal segment 453 and the first ground signal segment 41.

[0129] In one embodiment, Fig.17 As shown, the second section 12 also includes a second sub-section 14 located in the bending area 1212, and the second sub-section 14 is connected to the first sub-section 13; the second sub-section 14 is located in the second conductive layer 53. Since the distance between the first conductive layer and the touch layer is greater than the distance between the second conductive layer and the touch layer, the first sub-section 13 is arranged in the first conductive layer, so that in the direction perpendicular to the substrate, the distance between the first sub-section 13 and the fifth ground signal section 45 is larger, further reducing the signal interference of the fifth ground signal section 45 on the touch signal line 10; the second sub-section 14 is located in the second conductive layer of the pixel circuit layer, and the second sub-section 14 and the pixel circuit layer structure are formed at the same time, which does not increase the process complexity of the display substrate.

[0130] In one embodiment, Fig.17 As shown, the portion of the fourth ground signal segment 44 located in the bending area 1212 includes a seventh sub-segment 441 and an eighth sub-segment 442 . The seventh sub-segment 441 and the eighth sub-segment 442 are connected. The seventh sub-segment 441 is located in the first conductive layer, and the eighth sub-segment 442 is located in the second conductive layer 53 . Fig.17 In the illustrated embodiment, the seventh sub-segment 441 is located in the first sub-conductive layer 51 of the first conductive layer. This arrangement helps to improve the interference of static electricity on the ground signal line 40.

Fig.17 In the illustrated embodiment, the ninth sub-segment 411 is located in the first sub-conductive layer 51 of the first conductive layer. This arrangement helps to improve the interference of static electricity on the ground signal line 40.

[0133] In one embodiment, Fig.17 As shown, the portion of the first ground signal segment 41 located in the bending area 1212 includes two tenth sub-segments 412 , and both ends of the ninth sub-segment 411 are respectively connected to the tenth sub-segment 412 .
