Title:
液晶表示装置用GOA回路
Document Type and Number:
Japanese Patent JP6637981
Kind Code:
B2
Abstract:
A Gate Driver On Array (GOA) circuit for a liquid crystal display device. The liquid crystal display device comprises a plurality of scanning lines, and the GOA circuit comprises a plurality of cascaded shift register units. An Nth-level shift register unit controls charging of an Nth-level scanning line (G(N)). The Nth-level shift register unit comprises a forward and reverse scanning control circuit (100), a pull-up circuit (200), a bootstrap capacitor circuit (300), a gate signal point electric leakage prevention circuit (400) and a pull-down holding circuit (500). The bootstrap capacitor circuit (300), the gate signal point electric leakage prevention circuit (400) and the pull-down holding circuit (500) are connected together to form a gate signal point (Q) so as to improve the stability of the gate signal point (Q) and reduce the use of switches.
