Abstract

A scan circuit is provided. The scan circuit includes a plurality of stages. A respective stage of the scan circuit includes a respective scan unit configured to provide a control signal to one or more rows of subpixels. A respective scan unit includes a first subcircuit, a second subcircuit, a third subcircuit, a fourth subcircuit. A pull-up node is coupled to the second subcircuit, the third subcircuit, and the fourth subcircuit. A pull-down node is coupled to the second subcircuit, the third subcircuit. The denoising subcircuit is coupled to a pull-up node and the input terminal, or coupled between a third power supply voltage terminal and the pull-down control node.
