Title: GATE DRIVE CIRCUIT
Abstract:
A gate drive circuit, comprising multiple levels of gate drive units, wherein each level of gate drive units comprises an input control module (100), an output control module (200), a pull-down module (300), a pull-down maintaining module (400) and a compensation module (500). The compensation module (500) makes a threshold voltage (Vth) of a transistor not influence the potential of a first node (Q(N)), thereby significantly improving the stability of a gate drive circuit and being beneficial for improving the display effect of a liquid crystal display panel.
