Document Type and Number:
WIPO Patent Application WO/2017/107255
Kind Code:
A1
Abstract:
A gate driver on array (GOA) circuit (30) for use in a liquid crystal display device (20). The liquid crystal display device (20) comprises multiple scanning lines (G(1)-G(6)); the GOA circuit (30) comprises multiple GOA units (40); the multiple GOA units (40) are cascaded with each other to form multiple stages of GOA units (40); an nth-stage GOA unit (40) comprises a clock circuit (100), a pull-down circuit (200), a bootstrap capacitance circuit (300), a pull-up circuit (400), and a pull-down holding circuit (500). The present invention can resolve the tri-gate color cast problem and reduce the production costs.
