Abstract
A scan driving circuit includes a repair assembly, a pull-up assembly, a pull-up control assembly that drives the pull-up assembly, a pull-down maintaining assembly, and a reference low-level signal. When the pull-down maintaining assembly turns off in a work stage of a current scanning line, the repair assembly turns off. When the pull-down maintaining assembly turns on in the work stage of the current scanning line, the repair assembly is connected with the pull-down maintaining assembly. In the work stage of the current scanning line, the reference low-level signal is sent to the repair assembly via the turn-off unit, and turns off the pull-down maintaining assembly through the repair assembly.
