Title:
GOA DRIVING CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2018/040477
Kind Code:
A1
Abstract:
Disclosed is a GOA driving circuit, comprising a downlink unit (310). The downlink unit (310) comprises a downlink transistor (T22) and a voltage stabilization capacitor (Cs), wherein one polar plate thereof is connected to a source electrode of the downlink transistor (T22); the other polar plate thereof is connected to a common electrode (Acom); the common electrode (Acom) transmits a direct current voltage signal; and the voltage stabilization capacitor (Cs) produces a coupling voltage to maintain the stability of a downlink signal. The driving circuit can improve the reliability of a signal of a key node in the driving circuit and improve the stability of the displaying of a liquid crystal panel.
