Abstract
A display substrate includes a scan circuit, a first reference signal line in a third region, and at least three clock signal lines arranged in a fourth region. The scan circuit includes a plurality of stages, wherein a respective stage of the scan circuit includes a respective scan unit configured to provide a control signal to at least a row of subpixels. The respective scan unit includes an input subcircuit configured to receive from an input terminal a start signal or an output signal from a previous scan unit of a previous stage, a first processing subcircuit, a second processing subcircuit, and an output subcircuit configured to output an output signal from an output terminal. The output subcircuit includes a first output transistor. The input subcircuit includes a first input transistor and a second input transistor sequentially coupled between an input terminal and a first node.
