Abstract
The disclosure provides a GOA circuit, a driving method thereof and a liquid crystal display device. The GOA circuit comprises a plurality of GOA units connected in cascade, wherein the N-stage GOA unit comprises a N-stage stage circuit, a N-stage Q point control circuit, a N-stage P point circuit, a N-stage output circuit and a switch circuit. The switch circuit is connected to the N-stage scan line for sending a turn-on signal to the N-stage scan line before the liquid crystal display device displays an image such that the thin-film transistor in the pixel connected to the N-stage scan line turns on. The disclosure may turn on the gate of each pixel when the display device is waken from the black screen to prevent the electricity leakage when the display device is wakened from the black screen, and may also increase the stability of the circuit.
