Abstract
A scan driving circuit includes a pull controlling module for generating scan level signal based on transferring signals from the previous one stage and from the previous two stage, a pull-up module, a pull-down module, a pull-down holding module, a transferring module, a first bootstrap capacitor, a constant low voltage level source, and a second bootstrap capacitor for pulling up the scan level signal through the transferring signal from the previous one stage. The present invention upgrades a reliability of the scan driving circuit.
