Abstract
A display substrate, including: a plurality of partition control signal lines disposed on a base substrate; and a plurality of sub-pixels disposed on the base substrate, at least one of the sub-pixels includes a pixel circuit and a light emitting device. The pixel circuit includes a switch transistor, a first partition control transistor, a drive transistor and a first initialization transistor. The first partition control transistor is electrically connected to the switch transistor, the first initialization transistor, the drive transistor and at least one partition control signal line. The first partition control transistor is configured to: in response to a partition control signal on the partition control signal line, selectively transmit a received first initialization signal to a gate electrode of the drive transistor in an initialization phase, and selectively transmit a received data signal to the gate electrode of the drive transistor in a data writing phase.
