Abstract
A display substrate includes multiple sub-pixels, a sub-pixel includes a pixel drive circuit and a light emitting device, the pixel drive circuit includes an initial signal line, a reset signal line, a scan signal line and multiple transistors. Multiple transistors include a drive transistor, a data writing transistor, a first reset transistor and a second reset transistor. The first reset transistor resets a gate of the drive transistor under control of the reset signal line. The display substrate further comprises dummy pixel rows among the plurality of sub-pixels, at least one row of the plurality of sub-pixels is arranged adjacent to a dummy pixel row, the dummy pixel row comprises a plurality of dummy sub-pixels, a dummy sub-pixel comprises a dummy pixel drive circuit.
