Abstract
A gate drive circuit includes: N array substrate row drive circuits arranged in cascade, an Nth array substrate row drive circuit is configured for outputting an Nth gate drive signal in response to a signal input terminal receiving a gate drive signal output by an N−1th array substrate row drive circuit to control Nth sub-pixels to charge; N auxiliary circuits, a timing signal input terminal is connected to an Nth timing control signal, a controlled terminal is connected to a pull-up control signal terminal of the N−1th array substrate row drive circuit, and an output terminal is connected to a gate drive signal output terminal; and the Nth auxiliary circuit is configured for controlling the Nth sub-pixels to charge in a determination that the Nth timing control signal connected to the timing signal input terminal and an N−1th pull-up control signal connected to the controlled terminal are both high level.
