1. A display panel, comprising:
a display substrate, provided with a display region and a peripheral region surrounding the display region; and
a touch layer laminated on the display substrate, wherein the touch layer comprises a plurality of touch electrodes, a plurality of traces, and a flexible film, orthographic projections of the plurality of touch electrodes on the display substrate being within the display region, and orthographic projections of the plurality of traces on the display substrate being within the peripheral region, wherein a part of the touch electrodes and the traces are disposed on one surface of the flexible film, and the other part of the touch electrodes and the traces are disposed on the other surface of the flexible film;
wherein ends of the plurality of traces are connected to the corresponding touch electrodes, and the other ends of the plurality of traces are disposed in a plurality of bonding regions arranged at intervals in the touch layer, orthographic projections of the plurality of bonding regions on the display substrate being within a first peripheral sub-region, the first peripheral sub-region being a partial region, on a side of the display region, of the peripheral region, and the plurality of bonding regions being arranged along an extending direction of an outer edge of the first peripheral sub-region;
the peripheral region further comprises a second peripheral sub-region and a third peripheral sub-region, wherein the second peripheral sub-region and the third peripheral sub-region are connected to the first peripheral sub-region, and the second peripheral sub-region, the first peripheral sub-region and the third peripheral sub-region are respectively on sides where three connecting borders of the display region are disposed;
the plurality of traces comprise a first trace, a second trace and a third trace, wherein in an orthographic projection of the touch layer on the display substrate, the first trace is connected to the corresponding touch electrode from a border, close to the first peripheral sub-region, of the display region, the second trace is connected to the corresponding touch electrode from a border, close to the second peripheral sub-region, of the display region, and the third trace is connected to the corresponding touch electrode from a border, close to the third peripheral sub-region, of the display region; and
the plurality of bonding regions comprise a first bonding region corresponding to the first trace, a second bonding region corresponding to the second trace and a third bonding region corresponding to the third trace; wherein
the first bonding region is between the second bonding region and the third bonding region;
the traces in any first bonding region are connected to one first FPC, the traces in any second bonding region are connected to one second FPC, and the traces in any third bonding region are connected to one third FPC; and
a part of the first FPC, the second FPC and the third FPC are bonded to the traces on one surface of the touch layer, and the other part of the first FPC, the second FPC and the third FPC are bonded to the traces on the other surface of the touch layer.
