In two adjacent touch signal line groups, the first touch signal lines 104 and the second touch signal lines 105 are adjacent, and the first touch signal lines 104 and the second touch signal lines 105 are located on opposite sides of the first shielding segment 21 of the shielding line 20. In this manner, the shielding line 20 can prevent signal crosstalk between the first touch signal lines 104 and the second touch signal lines 105.
[0084] In one embodiment, the third conductive layer and the fourth conductive layer each include a plurality of grid-like structures, and an orthographic projection of each light-emitting structure on the substrate falls within an 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, as shown in FIG2B , the display substrate includes a display area 110 and a non-display area 120, with the non-display area 120 located on at least one side of the display area 110. In the embodiment shown in FIG2 , the non-display area 120 surrounds the display area 110 and 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. The non-display sub-area 121 is opposite the non-display sub-area 122, and the non-display sub-area 123 is opposite the non-display sub-area 124. The direction from the display area 110 toward the non-display sub-area 121 is a first direction Y.
[0087] In one embodiment, as shown in Figures 1 and 2B, 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. Touch signal lines 10, shielding lines 20, and other traces are connected to the binding terminals. The binding terminals can be bound to an FPC (Flexible Printed Circuit), so that a chip connected to the FPC can provide signals to the traces.
[0089] In one embodiment, at least a portion of the first shielding segment 21 and the first section 11 are located in the transition region 1211, and the second section 12 and the second shielding segment 22 are located in the transition region 1211, the bending region 1212, and the binding region 1213. In the embodiment shown in FIG1 , the first shielding segment 21 and the first section 11 are located only in the transition region 1211.
[0090] In one embodiment, as shown in FIG3 , at least the portion of the touch signal line 10 located in the transition region 1211 includes a first touch signal portion 102 and a second touch signal portion 103 located on a side of the first touch signal portion 102 away from the substrate. At least the portion of the shielding line 20 located in the transition region 1211 includes a first shielding portion 201 and a second shielding portion 202 located on a side of the first shielding portion 201 away from the substrate. The first touch signal portion 102 and the first shielding portion 201 are located on the third conductive layer 31 of the touch layer, while the second touch signal portion 103 and the second shielding portion 202 are located on the fourth conductive layer 32 of the touch layer. This helps reduce the resistance of the touch signal line 10 and the shielding line 20.
[0091] In one embodiment, at least the portion of the touch signal line 10 located in the binding area 1213 includes a first touch signal portion and a second touch signal portion located on a side of the first touch signal portion away from the substrate. At least the portion of the shielding line located in the binding area 1213 includes a first shielding portion and a second shielding portion located on a side of the first shielding portion away from the substrate. The first touch signal portion and the first shielding portion are located on the third conductive layer of the touch layer, while the second touch signal portion and the second shielding portion are located on the fourth conductive layer of the touch layer. This helps further reduce the resistance of the touch signal line 10 and the shielding line 20.
[0092] In one embodiment, as shown in Figures 1 and 4 , the first shielding segment 21 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 first shielding segment 21. Because 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, simplifying the structure and manufacturing process of the shielding line 20.
[0093] In one embodiment, as shown in Figures 1 and 5 , the shielding line 20 further includes a third shielding segment 23 located in the bonding area 1213. The third shielding segment 23 is located between two adjacent touch signal line groups 101. Within 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 bonding terminal. Thus, both second shielding segments 22 are connected to the bonding terminal via the third shielding segment 23, which helps simplify the wiring complexity of the display substrate.
[0094] In one embodiment, as shown in Figures 1 and 5 , the touch signal line 10 further includes a third segment 15 located in the binding area 1213 , which is connected to the binding terminal. The maximum distance between the third segments 15 of two adjacent touch signal line groups 101 is less than the maximum distance between the second segments 12 of two adjacent touch signal line groups 101. The third shielding segment 23 is located between the third segments 15 of the two touch signal line groups. Positioning the third shielding segment 23 between the two third segments 15 prevents signal crosstalk between the third segments 15 on either side of the third shielding segment 23.
[0095] In one embodiment, as shown in Figure 4 , the second shielding segment 22 is located within the transition region 1211. The width of the portion 2201 of the second shielding segment 22 extending along the first direction Y is greater than the width of the portion 2202 of the second shielding segment 22 extending along the second direction X intersecting the first direction Y. This arrangement helps reduce the width of the transition region 1211 in the first direction Y, thereby reducing the width of the display substrate's bezel. In the embodiment shown in Figure 4 , 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 acute.
[0096] In one embodiment, the touch signal line 10 is located in the transition region 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. This configuration helps reduce the width of the transition region 1211 in the first direction Y, thereby reducing the border width of the display substrate.
[0097] In one embodiment, as shown in Figures 6 to 8 , the first shielding segment 21 is located between two adjacent touch signal lines 10 in the same touch signal line group 101. The shielding line 20 also includes a connecting segment 24, through which the first shielding segment 21 is connected to the second shielding segment 22. The first shielding segment 21 is also connected to the binding terminal. Thus, the second shielding segment 22 is connected to the first shielding segment 21 via the connecting segment 24. The first shielding segment 21 can transmit the chip's signal to the second shielding segment 22, eliminating the need for the second shielding segment 22 to connect to the binding terminal, thus reducing the number of binding terminals.
[0098] 6 and 7 , 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, as shown in Figures 8 and 9 , the first shielding segment 21 is partially located between two adjacent second segments 12 of the same touch signal line group 101. The second segment 12 between the second shielding segment 22 and the first shielding segment 21, each connected to the connecting segment 24, includes a first sub-segment 13. 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 on different conductive layers. This prevents short circuits between the connecting segment 24 and the first sub-segment 13.
[0100] In one embodiment, as shown in Figures 8-10 , 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 includes only the first touch signal portion 102, and the connecting segment 24 includes only 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 through-holes 205. The portions of the second segment 12 located in the fourth conductive layer 32 and on either side of the connecting segment 24 are electrically connected to the third conductive layer 31 via the through-holes 205.
[0101] Furthermore, as shown in FIG6 , the connecting segment 24 is located in the transition region 1211. In another embodiment, as shown in FIG7 , the connecting segment 24 is located in the binding region 1213. To facilitate bending of the display substrate in the bending region, the thickness of the bending region is relatively small. Generally, the touch layer is hollowed out in the bending region, and the portion of the touch signal line located in the bending region is disposed in the conductive layer of the pixel circuit layer. Therefore, when the connecting segment 24 and the first sub-segment 13 are disposed in the touch layer, the connecting segment 24 and the first sub-segment 13 are located in the binding region or transition region.
[0102] In one embodiment, the first sub-segment 13 is located in the first conductive layer, and the connecting segment 24 is located in the conductive layer of the touch layer. This arrangement allows for a greater distance between the first sub-segment 13 and the connecting segment 24 in a direction perpendicular to the substrate, reducing signal interference from the connecting segment 24 on the touch signal line 10 and helping to improve the touch accuracy of the display substrate. Furthermore, since the first sub-segment 13 is located in the first conductive layer of the pixel circuit layer, the first sub-segment 13 is formed simultaneously with the structure of the pixel circuit layer, without increasing the manufacturing complexity of the display substrate.
[0103] Furthermore, as shown in Figures 11 and 12, the first sub-segment 13 and the connecting segment 24 are located in the bending region 1212. Specifically, the first sub-segment 13 and the connecting segment 24 are located in the edge of the bending region 1212 near the binding region 1213. Because the touch signal lines and shielding lines located in the bending region are disposed in the conductive layer of the pixel circuit layer, disposing the first sub-segment 13 in the first conductive layer of the pixel circuit layer does not increase the complexity of the display substrate manufacturing process.
[0104] In one embodiment, as shown in FIG12 , the second segment 12 further includes a second sub-segment 14 located in the bend region 1212 . The second sub-segment 14 is connected to the first sub-segment 13 . The second sub-segment 14 is located in the second conductive layer 53 . Because 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, positioning the first sub-segment 13 in the first conductive layer increases the distance between the first sub-segment 13 and the connecting segment 24 in a direction perpendicular to the substrate, further reducing signal interference from the connecting segment 24 on the touch signal line 10 . Positioning the second sub-segment 14 in the second conductive layer of the pixel circuit layer allows the second sub-segment 14 and the pixel circuit layer structures to be formed simultaneously, without increasing the manufacturing complexity of the display substrate.
[0105] In one embodiment, as shown in FIG12 , the portion of the touch signal line 10 located in the bend region 1212 includes two second sub-segments 14, with both ends of the first sub-segment 13 connected to the second sub-segments 14. Disposing the first sub-segment 13 of the touch signal line 10 located in the bend region 1212 on the side of the second sub-segment 14 facing the substrate helps reduce static electricity interference on the touch signal line 10.
[0106] In one embodiment, as shown in FIG12 , the connecting segment 24 is located on the fourth conductive layer 32 of the touch layer. This increases the distance between the first sub-segment 13 and the connecting segment 24 in a direction perpendicular to the substrate, further reducing signal interference from the connecting segment 24 on the touch signal line 10 and improving the touch accuracy of the display substrate.
[0107] In one embodiment, as shown in FIG12 , 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, as shown in Figure 12 , the portion of the second shielding segment 22 located in the bend region 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. In the embodiment shown in Figure 12 , the third sub-segment 221 is located in the first sub-conductive layer 51 of the first conductive layer. This configuration helps to reduce static electricity interference on the shielding wire 20.
[0109] In one embodiment, as shown in FIG. 12 , the portion of the second shielding segment 22 located in the bending region 1212 includes two fourth sub-segments 222 , and both ends of the third sub-segment 221 are respectively connected to the fourth sub-segment 222 .
[0110] In one embodiment, as shown in Figure 12 , the portion of the first shielding segment 21 located in the bend region 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. In the embodiment shown in Figure 12 , the fifth sub-segment 211 is located in the second sub-conductive layer 52 of the first conductive layer. This configuration helps to reduce static electricity interference on the shielding wire 20.
[0111] In one embodiment, as shown in FIG. 12 , the portion of the first shielding segment 21 located in the bending region 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, as shown in FIG12 , two adjacent traces are located in portions of 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 prevents short circuits between adjacent traces located in the first conductive layer.
[0113] In one embodiment, as shown in Figure 12, the connecting segment 24 sequentially connects the first sub-segment 241, the second sub-segment 242, and the third sub-segment 243. The orthographic projection of the second sub-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-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-segment 243 on the substrate falls within the orthographic projection of the second shielding segment 22 on the substrate. Because the signals of the first sub-segment 241, the third sub-segment 243, the first shielding segment 21, and the second shielding segment 22 are the same, there is no interference between the first sub-segment 241 and the first shielding segment 21, and no interference between the third sub-segment 243 and the second shielding segment 22.
[0114] In one embodiment, as shown in FIG13 , the display substrate further includes a ground signal line 40, which 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. This arrangement of the first ground signal segment 41 and the second ground signal segment 42 further reduces interference with the touch signal line from static charge and other signal lines, thereby further improving the touch accuracy of the display substrate.
[0115] In one embodiment, at least the portion of the ground signal line 40 located in the bonding 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 further reduce the resistance of the ground signal line 40.
[0116] In one embodiment, as shown in FIG13 , the ground signal line 40 further includes a third ground signal segment 43. The first ground signal segment 41 and the second ground signal segment 42 are each connected to the same third ground signal segment 43, which is in turn connected to the binding terminal. This configuration simplifies the routing complexity of the display substrate.
[0117] 13 , the shielding line 20 includes a third shielding segment 23 located in the bonding area 1213, and the third ground signal segment 43 is adjacent to the third shielding segment 23. This configuration further reduces signal crosstalk between the third ground signal segment and the touch signal lines on both sides of the third ground signal segment.
[0118] Furthermore, as shown in FIG. 13 , 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, as shown in FIG14 , 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 and the second ground signal segment 42 are connected. 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. 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 touch signal lines from interference from external static electricity and other signal lines.
[0120] Furthermore, as shown in Figure 14, the fourth ground signal segment 44 is connected to the first ground signal segment 41 via the fifth ground signal segment 45; the fourth ground signal segment 44 is also connected to the binding terminal. This allows 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 to carry the same signal, eliminating the need for signal segments connecting the first and second ground signal segments to the binding terminal, thus simplifying routing complexity.
[0121] Furthermore, as shown in FIG14 , the ground signal line 40 further includes a sixth ground signal segment 46. 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 reduce interference with 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 disposed around the periphery of the display area, with the sixth ground signal segment 46 and the fourth ground signal segment 44 each forming part of the shielding ring.
[0122] In one embodiment, as shown in FIG15 , the second segment 12 includes a first sub-segment 13; the second shield segment 22 includes a third sub-segment 221; and the first shield segment 21 includes a fifth sub-segment 211. The orthographic projection of the fifth ground signal segment 45 on the substrate overlaps with the orthographic projections of the first sub-segment 13, the third sub-segment 221, and the fifth sub-segment 211 on the substrate. The fifth ground signal segment 45 and the first sub-segment 13, the third sub-segment 221, and the fifth sub-segment 211 are located on different conductive layers to prevent short circuits. The first insulating layer 247 is provided with a through-hole 205. The portions of the second segment 12, the first shield segment 21, and the second shield segment 22 located on the fourth conductive layer 32 and on both sides of the connecting segment 24 are electrically connected to the third conductive layer 31 via 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, as shown in FIG14 , 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 region 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 region 1213. To facilitate bending of the display substrate in the bending region, the thickness of the bending region is relatively small. Generally, the touch layer is hollowed out in the bending region, and the portion of the touch signal line located in the bending region is disposed in 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 disposed 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 region or transition region.
[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. This arrangement allows for a greater 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 in a direction perpendicular to the substrate, thereby reducing signal interference from the fifth ground signal segment 45 on the touch signal line 10 and the shielding line, thereby improving the touch accuracy of the display substrate. Furthermore, since 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, 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, thereby not increasing the manufacturing complexity of the display substrate.
[0126] Furthermore, as shown in Figures 16 and 17, 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 region 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 region of the bending region 1212 near the binding region 1213. Because the touch signal lines, ground signal lines, and shielding lines located in the bending region are disposed in the conductive layer of the pixel circuit layer, disposing the first sub-segment 13, the third sub-segment 221, and the fifth sub-segment 211 in the first conductive layer of the pixel circuit layer does not increase the complexity of the display substrate manufacturing process. The connecting segment 24 may also be located in the bending region 1212, and the fifth ground signal segment 45 and the connecting segment are located in the edge region adjacent to the bending region 1212 and the binding region 1213.
[0127] 17 , the fifth ground signal segment 45 is located in the fourth conductive layer 32. This arrangement allows the fifth ground signal segment 45 to be further away from the first sub-segment 13, the fourth sub-segment 222 of the second shield segment 22, and the sixth sub-segment 212 of the first shield segment 21 in a direction perpendicular to the substrate.
[0128] Furthermore, as shown in FIG17 , 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, which are connected in sequence. 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. Because 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, no interference occurs between the first sub-ground signal segment 451 and the fourth ground signal segment 44, and no interference occurs between the third sub-ground signal segment 453 and the first ground signal segment 41.
[0129] In one embodiment, as shown in FIG17 , the second segment 12 further includes a second sub-segment 14 located in the bend region 1212 . The second sub-segment 14 is connected to the first sub-segment 13 ; the second sub-segment 14 is located in the second conductive layer 53 . Because 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, positioning the first sub-segment 13 in the first conductive layer increases the distance between the first sub-segment 13 and the fifth ground signal segment 45 in a direction perpendicular to the substrate, further reducing signal interference from the fifth ground signal segment 45 on the touch signal line 10 . Positioning the second sub-segment 14 in the second conductive layer of the pixel circuit layer allows the second sub-segment 14 and the pixel circuit layer structures to be formed simultaneously, without increasing the manufacturing complexity of the display substrate.
[0130] In one embodiment, as shown in FIG17 , the portion of the fourth ground signal segment 44 located in the bend region 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. In the embodiment shown in FIG17 , the seventh sub-segment 441 is located in the first sub-conductive layer 51 of the first conductive layer. This configuration helps to reduce static electricity interference with the ground signal line 40.
[0131] In one embodiment, as shown in FIG. 17 , the portion of the fourth ground signal segment 44 located in the bending region 1212 includes two eighth sub-segments 442 , and both ends of the seventh sub-segment 441 are respectively connected to the eighth sub-segment 442 .
[0132] In one embodiment, as shown in FIG17 , the portion of the first ground signal segment 41 located in the bend region 1212 includes a ninth sub-segment 411 and a tenth sub-segment 412. The ninth sub-segment 411 and the tenth sub-segment 412 are connected. The ninth sub-segment 411 is located in the first conductive layer, and the tenth sub-segment 412 is located in the second conductive layer 53. In the embodiment shown in FIG17 , the ninth sub-segment 411 is located in the first sub-conductive layer 51 of the first conductive layer. This configuration helps to reduce static electricity interference with the ground signal line 40.
[0133] In one embodiment, as shown in FIG. 17 , the portion of the first ground signal segment 41 located in the bending region 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 .
[0134] In one embodiment, as shown in FIG17 , two adjacent traces are located in portions of 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 prevents short circuits between adjacent traces located in the first conductive layer.
