In an embodiment, in a direction perpendicular to the display panel, the front projection of the first interference-reducing hole 1041 and the front projection of the second interference-reducing hole 1042 are adjacent to each other on the display panel, and it can be understood that by setting the front projection of the first interference-reducing hole 1041 and the front projection of the second interference-reducing hole 1042 to be adjacent to each other on the display panel, the overlapping area between the signal trace and the touch signal trace is further reduced, and the signal interference between the signal trace and the touch signal trace is further reduced.
In an embodiment, as shown in fig. 8, the touch trace layer 102 includes a first touch trace layer 102a and a second touch trace layer 102b; the second interference reducing hole 1042 includes a plurality of first interference reducing holes 1041a located on the first touch trace layer 102a and a plurality of second interference reducing holes 1041b located on the second touch trace layer 102b, and in a direction perpendicular to the display panel, the front projections of the first interference reducing holes 1041a and the front projections of the second interference reducing holes 1041b are all spaced from the front projections of the first interference reducing holes 1041.
Specifically, the touch trace layer 102 may be a touch signal line of a self-capacitance type touch structure or a mutual-capacitance type touch structure, when the touch trace layer 102 has two layers including a first touch trace 102a and a second touch trace 102b, an insulating layer 304 is disposed between the first touch trace layer 102a and the second touch trace layer 102b, and the touch signal lines of the two layers of touch trace layers 102 are provided with interference reducing holes 104, that is, interference reducing sub-holes 1041a and interference reducing sub-holes 1041b, in a direction perpendicular to the display panel, forward projections of the interference reducing sub-holes 1041a and forward projections of the interference reducing sub-holes 1041b are all set at intervals with forward projections of the first interference reducing holes 1041, and the forward projections of the interference reducing sub-holes 1041a and the interference reducing sub-holes 1041b may not overlap.
It can be understood that by arranging the first hole 1041a for reducing the interference on the first touch trace layer 102a and the second hole 1041b for reducing the interference on the second touch trace layer 102b, the signal interference of the trace between the touch trace layer 102 and the signal trace layer 103 is obviously reduced, and the touch accuracy and the display effect of the display panel are improved.
In an embodiment, as shown in fig. 8, the touch trace layer 102 includes a first touch trace layer 102a and a second touch trace layer 102b; the second interference-reducing holes 1042 include a plurality of first interference-reducing holes 1041a located on the first touch-control wiring layer 102a and a plurality of second interference-reducing holes 1041b located on the second touch-control wiring layer 102b, wherein a vertical distance between the first touch-control wiring layer 102a and the signal wiring layer 103 is greater than a vertical distance between the second touch-control wiring layer 102b and the signal wiring layer 103, and a forward projection area of the first interference-reducing holes 1041a is smaller than a forward projection area of the second interference-reducing holes 1041b in a direction perpendicular to the display panel;
it can be understood that, by setting the first hole 1041a for reducing the interference on the first touch trace layer 102a and setting the second hole 1041b for reducing the interference on the second touch trace layer 102b, the further the vertical distance between the first touch trace layer 102a and the second touch trace layer 102b from the signal trace layer 103 is, the weaker the signal interference between the traces on the touch trace layer 102 and the signal trace layer 103 is, so in the direction perpendicular to the display panel, the smaller the orthographic projection area of the first hole 1041a for reducing the interference is than the orthographic projection area of the second hole 1041b for reducing the signal interference between the touch trace layer 102 and the signal trace layer 103, and meanwhile, the smaller the area of the opening of the interference reducing hole 104 is, the higher the impedance of the trace is, the longer the service life of the trace is, and the service life of the display panel is effectively prolonged while the signal interference between the signal traces is at a lower level.

Specifically, on the signal trace layer 103, among two adjacent signal traces, the signal trace near the trace bending region 40 receives a bending stress greater than that received by the signal trace far from the trace bending region 40, so that the density of the first overlapping-group inner interference-reducing holes 104 on the signal trace near the trace bending region 40 is set to be greater than that of the first overlapping-group inner interference-reducing holes 104 on the signal trace far from the trace bending region 40.
It can be appreciated that by adopting the above scheme, the bending performance of the signal wire close to the wire bending region 40 is stronger, so that bending stress on the signal wire close to the wire bending region 40 can be effectively dispersed, and the service life of the signal wire can be effectively prolonged.
In an embodiment, the second overlapping portion includes a plurality of second overlapping sub-portions, the second overlapping sub-portions are provided with anti-interference holes, the second overlapping sub-portions include a plurality of second overlapping groups, each second overlapping group includes more than two second overlapping sub-portions, and in any two adjacent second overlapping groups, an arrangement density of the interference reducing holes 104 in the second overlapping group far from the routing bending region 40 is less than an arrangement density of the interference reducing holes 104 in the second overlapping group near the routing bending region 40.
