In an embodiment, in a direction perpendicular to the display panel, the orthographic projection of the first interference reduction hole 1041 and the orthographic projection of the second interference reduction hole 1042 are adjacent to each other on the display panel, and it can be understood that by arranging the orthographic projection of the first interference reduction hole 1041 and the orthographic projection of the second interference reduction hole 1042 to be adjacent to each other on the display panel, an overlapping area between the signal traces and the touch signal lines is further reduced, and signal interference between the signal traces and the touch signal lines is further reduced.
In an embodiment, as shown in fig. 8, the touch routing layer 102 includes a first touch routing layer 102a and a second touch routing layer 102 b; the second interference reducing holes 1042 include a plurality of first interference reducing holes 1041a located on the first touch wiring layer 102a and a plurality of second interference reducing holes 1041b located on the second touch wiring layer 102b, and in a direction perpendicular to the display panel, an orthographic projection of the first interference reducing holes 1041a and an orthographic projection of the second interference reducing holes 1041b are both spaced from an orthographic projection of the first interference reducing holes 1041.
Specifically, the touch routing layer 102 can be a touch signal line of a self-contained touch structure or a touch signal line of a mutual-contained touch structure, when the touch routing layer 102 has two layers, including the first touch routing 102a and the second touch routing 102b, wherein, an insulating layer 304 is disposed between the first touch wiring layer 102a and the second touch wiring layer 102b, interference reduction holes 104 are disposed on the touch signal lines of the two touch wiring layers 102, namely, a first hole for jammer 1041a and a second hole for jammer 1041b, wherein, in a direction perpendicular to the display panel, the orthographic projection of the first interference reduction hole 1041a and the orthographic projection of the second interference reduction hole 1041b are both arranged at intervals with the orthographic projection of the first interference reduction hole 1041, the orthographic projection of the first hole 1041a of the descending disturber and the orthographic projection of the second hole 1041b of the descending disturber may or may not overlap.
It can be understood that by disposing the first hole 1041a of the interference reduction sub on the first touch wiring layer 102a and disposing the second hole 1041b of the interference reduction sub on the second touch wiring layer 102b, the signal interference of the trace between the touch wiring layer 102 and the signal wiring layer 103 is significantly reduced, and the touch precision and the display effect of the display panel are improved.
In an embodiment, as shown in fig. 8, the touch routing layer 102 includes a first touch routing layer 102a and a second touch routing layer 102 b; the second interference reduction holes 1042 include a plurality of interference reduction sub-first holes 1041a located on the first touch routing layer 102a and a plurality of interference reduction sub-second holes 1041b located on the second touch routing layer 102b, a vertical distance between the first touch routing layer 102a and the signal routing layer 103 is greater than a vertical distance between the second touch routing layer 102b and the signal routing layer 103, and an orthographic projection area of the interference reduction sub-first holes 1041a is smaller than an orthographic projection area of the interference reduction sub-second holes 1041b in a direction perpendicular to the display panel;
it can be understood that by disposing the interference reducing sub-first hole 1041a on the first touch wiring layer 102a and disposing the interference reducing sub-second hole 1041b on the second touch wiring layer 102b, since the vertical distance between the first touch wiring layer 102a and the second touch wiring layer 102b and the signal wiring layer 103 is different, the farther from the signal wiring layer 103, the weaker the signal interference between the traces of the touch wiring layer 102 and the signal wiring layer 103, therefore, in the direction perpendicular to the display panel, the smaller the orthographic area of the interference reducing sub-first hole 1041a is disposed than the orthographic area of the interference reducing sub-second hole 1041b, the signal interference between the touch wiring layer 102 and the signal wiring layer 103 can be reduced, and meanwhile, the smaller the area of the opening of the interference reducing hole 104, the higher the impedance, the longer the service life of the trace, and the lower the signal interference between the signal lines is ensured to be at a lower level, the service life of the display panel is effectively prolonged.

Specifically, on the signal trace layer 103, of two adjacent signal traces, the bending stress applied to the signal trace close to the trace bending region 40 is greater than the bending stress applied to the signal trace far from the trace bending region 40, so that the density of the first overlap inner drop interference holes 104 on the signal trace close to the trace bending region 40 is set to be greater than the density of the first overlap inner drop interference holes 104 on the signal trace far from the trace bending region 40.
It can be understood that, by adopting the above scheme, the bending performance of the signal trace close to the trace bending region 40 is stronger, the bending stress on the signal trace close to the trace bending region 40 can be effectively dispersed, and the service life of the signal trace is effectively prolonged.
In an embodiment, the second overlapping portion includes a plurality of second overlapping portions, each of the second overlapping portions includes a plurality of second overlapping groups, each of the second overlapping groups includes more than two second overlapping portions, and in any two adjacent second overlapping groups, an arrangement density of the interference reducing holes 104 in one of the second overlapping groups far from the trace bending region 40 is less than an arrangement density of the interference reducing holes 104 in the second overlapping group near the trace bending region 40.
Specifically, on the touch wiring layer 102, of two adjacent touch signal lines, the bending stress applied to the touch signal line close to the wiring bending region 40 is greater than the bending stress applied to the touch signal line far from the wiring bending region 40, so that the density of the second inter-stack interference reduction holes 104 on the touch signal line close to the wiring bending region 40 is set to be greater than the density of the second inter-stack interference reduction holes 104 on the touch signal line far from the wiring bending region 40.
