Abstract
A scan circuit is provided. The scan circuit includes a plurality of scan units in a plurality of stages, respectively. A respective scan unit of the plurality of scan units includes an output subcircuit. The output subcircuit includes a first switch transistor and a second switch transistor. A source electrode of the first switch transistor is coupled to a third terminal configured to receive a first clock signal. A drain electrode of the first switch transistor is coupled to a first output terminal configured to output a first control signal. A source electrode of the second switch transistor is coupled to a fourth terminal configured to receive the third clock signal. A drain electrode of the second switch transistor is coupled to a second output terminal configured to output a second control signal. Gate electrodes of the first switch transistor and the second switch transistor are coupled to a first node.
