Title:
GOA CIRCUIT FOR LIQUID CRYSTAL DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/106803
Kind Code:
A1
Abstract:
Disclosed is a Gate Driver On Array (GOA) circuit for a liquid crystal display device. The liquid crystal display device comprises a plurality of scanning lines. The GOA circuit comprises a plurality of cascaded GOA units. An Nth-level GOA unit controls charging of an Nth-level scanning line (G(N)) in a display area. The Nth-level GOA unit comprises a forward and reverse scanning control circuit (100), a pull-up circuit (200), a bootstrap capacitor circuit (300), a pull-up control circuit (400) and a pull-down holding circuit (500). The pull-up circuit (200), the bootstrap capacitor circuit (300), the pull-up control circuit (400) and the pull-down holding circuit (500) are connected to a gate signal point (Q(N)). The pull-up circuit (200), the bootstrap capacitor circuit (300) and the pull-down holding circuit (500) are connected to the Nth-level scanning line (G(N)). The forward and reverse scanning control circuit (100) is connected to an (N-1)th-level scanning line (G(N-1)) and an (N+1)th-level scanning line (G(N+1)). The GOA circuit is used for improving the stability of the gate signal point and reducing the use of transistors.
