An integrated gate driver circuit includes a control circuit, a plurality of drive stages and a plurality of discharge transistors. The control circuit is configured to output a plurality of clock signals within a frame period and to output a discharge enabling signal within a blanking period of the frame period. Each of the drive stages receives the clock signals and includes an output terminal configured to output a gate driving signal. Each of the discharge transistors is coupled to the output terminal of one of the drive stages and discharges the output terminal according to the discharge enabling signal thereby eliminating the voltage fluctuation of the output terminal in the blanking period.
