1. A display substrate, comprising:
a substrate;
a plurality of pixels, disposed on a side of the substrate, each of the pixels comprising a pixel circuit and a light-emitting element, wherein the pixel circuit is coupled to a first electrode of the light-emitting element, a second electrode of the light-emitting element is coupled to a first power line, the pixel circuit is configured to transmit a drive signal to the first electrode of the light-emitting element, and the light-emitting element is configured to emit light based on the drive signal and a first power signal supplied by the first power line; and
at least one second power line and a plurality of repair lines that are disposed on a side of the substrate, wherein the second power line is coupled to the repair line, an orthographic projection of the repair line on the substrate being overlapped with an orthographic projection of the first electrode of the light-emitting element on the substrate, the repair line is configured to couple the second power line to a first electrode of a light-emitting element in a defective pixel in the plurality of pixels, and the second power line is configured to transmit a second power signal to the first electrode of the coupled light-emitting element by the repair line;
wherein the defective pixel comprises a dark pixel, and a potential of the second power signal is greater than a potential of the first power signal.
