1. A display substrate, comprising:
a base substrate, comprising:
a display area; and
a frame area around the display area;
a plurality of touch electrodes in the display area; and
a plurality of signal lines in the frame area;
wherein at least some of the signal lines are electrically connected to the plurality of touch electrodes; and
the signal lines comprise:
a first signal line and a second signal line adjacent to each other;
wherein the first signal line and the second signal line each comprises:
a first-layer wiring and/or a second-layer wiring, overlapping with each other in a direction perpendicular to the base substrate and electrically connected to each other;
a line width of the first signal line is greater than a line width of the second signal line; and
the first-layer wiring of the second signal line is disconnected, and the first-layer wiring of the first signal line is continuous;
wherein the display substrate further comprises:
a bridge layer between the base substrate and a layer where the plurality of touch electrodes are located; and
an insulating layer between the bridge layer and the layer where the plurality of touch electrodes are located;
wherein the first-layer wiring of the signal lines is arranged in a same layer as the plurality of touch electrodes, and the second-layer wiring is arranged in a same layer as the bridge layer.
