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.

Abstract: A pixel compensation method includes determining an actual driving digital voltage of each organic light-emitting sub-pixel in a detection row; performing mean value calculation based on the actual driving digital voltage of each organic light-emitting sub-pixel in the detection row to determine an average driving digital voltage corresponding to the detection row; calculating a voltage difference between the actual driving digital voltage of the organic light-emitting sub-pixel in the detection row and the average driving digital voltage, and counting the voltage differences to form a voltage difference set; and outputting a corresponding data compensation analog voltage to the organic light-emitting sub-pixel in the detection row when an absolute value of a maximum voltage difference in the voltage difference set is greater than or equal to a target threshold. The pixel compensation method of this disclosure can improve the uneven display and improve the display effect.
