Title:
GATE DRIVE CIRCUIT AND LIQUID CRYSTAL DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/040390
Kind Code:
A1
Abstract:
A gate drive circuit and a liquid crystal display device. The gate drive circuit comprises multiple stages of gate drive units. Each stage of gate drive unit comprises a pull-down maintaining module (400) for maintaining the potential of an output end (G(N)) of a gate drive unit of the present stage at a negative potential, so that the influence on the gate drive circuit caused by a threshold voltage of the 82nd transistor (T82) drifting to the right can be prevented, and the pull-down speed of the potential of a first node (Q(n)) can also be increased.
