1. A display panel, comprising a display area and a peripheral area located at the periphery of the display area, wherein at least one side of the peripheral area is a binding side connected with a binding circuit, and the peripheral area is provided with an isolation dam arranged at least partially around the display area;
the display panel comprises:
a substrate;
a display functional layer, wherein the display functional layer comprises display units located in the display area, and a plurality of display signal traces that are located in at least part of the peripheral area and are connected with the display units; and
a touch-control functional layer, wherein the touch-control functional layer comprises a touch-control pattern located in the display area, and a plurality of touch-control signal traces located in at least part of the peripheral area, and the touch-control signal trace and the display signal trace are arranged in different layers;
wherein on the binding side, there are a first boundary and a second boundary arranged opposite to each other, and a first trace area located between the first boundary and the second boundary, and the first boundary is closer to the display area than the second boundary;
in the first trace area, the touch-control signal trace is arranged along a first direction and are led out from the binding circuit and connected to the touch-control pattern via the isolation dam and the first trace area in sequence, the display signal trace is arranged along a second direction intersecting with the first direction, and there is an intersection area between orthographic projections of the display signal trace and the touch-control signal trace onto the substrate;
wherein the display panel further comprises a signal shielding layer between the touch-control signal traces and the display signal traces in a direction perpendicular to the substrate, and an orthographic projection of the signal shielding layer onto the substrate at least partially covers the intersection area of the touch-control signal trace and the display signal trace within the first trace area.
