Title:
CHARGING SCANNING AND CHARGE SHARING SCANNING DUAL-OUTPUT GOA CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2016/082340
Kind Code:
A1
Abstract:
A charging scanning and charge sharing scanning dual-output GOA circuit, combining a timing with a circuit; an nth stage GOA unit circuit receives a first low frequency clock signal (LC1), a second low frequency clock signal (LC2), a direct-current low voltage signal (Vss), an Mth high frequency clock signal (CK(M)), an (M-2)th high frequency clock signal (CK(M-2)), a stage transmission signal generated by an (n-2)th stage GOA unit circuit (ST(n-2)), a charging scanning signal generated by the (n-2)th stage GOA unit circuit (CG(n-2)) and a stage transmission signal generated by an (n+2)th stage GOA unit circuit (ST(n+2)); outputting a charging scanning signal (CG(n)), a charge sharing scanning signal of the (n-2)th stage GOA unit circuit (SG(n-2)) and a stage transmission signal (ST(n)) respectively via different TFTs; the nth GOA unit circuit comprises: a downloading module (100), a stage transmission voltage stabilization module (200), an output module (300), a rapid pull-down module (400) and a pull-down maintaining module (500).
