Abstract
Disclosed is a GOA circuit, including GOA units, which are cascade coupled. An nth stage GOA unit charges nth stage, n+1th stage and n+2th stage horizontal scanning lines. The nth stage GOA unit includes a pull-up control circuit, receiving a start signal CT and outputting a pull-up control signal Q(n); a pull-up circuit, receiving Q(n), an nth stage clock signal CK(n), an n+1th stage clock signal CK(n+1) and an n+2th stage clock signal CK(n+2), and outputting an nth stage transfer signal ST(n), an nth stage scan driving signal G(n), an n+1th stage scan driving signal G(n+1) and an n+2th stage scan driving signal G(n+2); a pull-down circuit, receiving an n+6th stage scan driving signal G(n+6) and a first direct current low voltage signal VSSQto enable Q(n) in an off state. Three stages scan driving signals can be outputted through one stage GOA unit.
