Abstract:
The present disclosure provides a scan driving circuit for driving an Nth-stage scanning line including: a pull-up control module for receiving a cascade signal of an upper stage and generating a scan level signal of the Nth-stage scanning line based on the cascade signal of the upper stage; a pull-up module for pulling down the scanning signal of the Nth-stage scanning line when the first clock signal is low according to the scan level signal and the first clock signal; the pull-up control module includes a first control unit and a second control unit, the control terminal of the second control unit inputs a second clock signal for controlling the scan level signal to become smaller when the second clock signal is at a high level. The present disclosure can prevent the waveform of the gate from appearing spikes, and thus the waveform of the gate is output normally.
