Abstract
The present invention provides a scan-driving circuit used to perform a driving operation on cascaded scanning lines, which comprises a pull-up control module, a pull-up module, a pull-down module, a pull-down sustain module, a down-transmitting module and a bootstrap capacitor. The scan-driving circuit of the present invention enhances the voltage-level control capability of the Q point and raises the reliability of the scan-driving circuit, by disposing a first constant-high voltage and a second constant-high voltage.
