Provided is a display substrate, including: a substrate; a plurality of pixels disposed on a side of the substrate, each of the pixels including a pixel circuit and a light-emitting element; and at least one second power line and a plurality of repair lines that are disposed on a side of the substrate. 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. The second power line is coupled to the repair line. 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. A potential of the second power signal is greater than a potential of the first power signal.
