Abstract
A scan-driving device is disclosed herein. The scan-driving device comprises a plurality of scan-driving circuits, a detective-driving circuit, and a modulating module. The scan-driving circuit comprises a n up-pull control module, an up-pull module, a down-transfer module, a down-pull module, a down-pull-sustain module, a bootstrap capacitor. The detective-driving circuit in the scan-driving device of the present invention is able to better maintain the ability of down-pull-sustain of the down-pull-sustain module, whereby the stability of the scan-driving device is increased.
