Abstract:
A gate driver on array (GOA) circuit includes a plurality of stages of GOA units cascaded. A first control latch module, a signal processing module, and a second control latch module of an Nth stage GOA unit generate an Nth stage dipulse gate driving signal and an Nth stage cascade signal according to clock signals, and an (N−2)th or (N+2)th stage cascade signal. For the clock signals corresponding to adjacent two stages of the GOA units, a first clock signal is delayed for a predetermined period of time with respect to a second clock signal. The two dipulse gate driving signals generated by the adjacent two stages of the GOA units partially overlap.
