Abstract: A gate drive circuit includes a charging circuit, a first shutdown circuit and a second shutdown circuit, and a first startup circuit and a second startup circuit. The charging circuit includes an energy storage element, a first switch unit and a second switch unit. The energy storage element switches between charging and discharging states based on control signals responded by control terminals of the first switch unit and the second switch unit. Control terminals of the first shutdown/startup circuit and second shutdown/startup circuit respond to the shutdown/startup control signal when the energy storage element is in the discharging state so that output terminals of the first shutdown/startup circuit and the second shutdown/startup circuit output two shutdown/startup signals to the sub-pixel.
