1. A display substrate, comprising:
a base substrate comprising a display area and a peripheral area surrounding the display area, wherein the display area comprises a pixel array comprising a plurality of sub-pixels, and wherein the peripheral area comprises a bending area located at a first side of the display area, and a shift register located at at least one of a second side or a third side of the display area, the first side is adjacent to the second side and the third side,
a plurality of signal lines, wherein one end of each of the plurality of signal lines is led out from the bending area, and the other end of each of the plurality of signal lines is connected with the shift register,
a first power line led out from the bending area and routed around the display area,
at least one first detection signal line arranged at at least one of a side where the shift register is located or a fourth side opposite to the first side of the display area, wherein a first end of the at least one first detection signal line is led out from the bending area, and
at least one second detection signal line arranged at at least one of the side where the shift register is located or the fourth side, wherein a first end of the at least one second detection signal line is led out from the bending area,
wherein at a side close to the bending area and outside an area where an orthographic projection of the first power line on a substrate surface of the base substrate is located, an orthographic projection of the at least one first detection signal line on the substrate surface of the base substrate has no overlap with orthographic projections of the plurality of signal lines on the substrate surface of the base substrate, and an orthographic projection of the at least one second detection signal line on the substrate surface of the base substrate has no overlap with the orthographic projections of the plurality of signal lines on the substrate surface of the base substrate.
