Abstract
Provided A gate drive circuit includes: a first frame start signal line and a cascade circuit. The first frame start signal line is connected to a first input terminal of the cascade circuit, configured to transmit a first frame start signal to the cascade circuit in a first display stage. The cascade circuit includes shift registers. Each shift register is connected to a clock signal line. An output terminal of each shift register is connected to a writing module in a pixel drive circuit. The cascade circuit is configured to output first scanning signals stage by stage according to the first frame start signal and a clock signal from the clock signal line. The effective level of the first frame start signal in one period overlaps with a plurality of pulse signals of the clock signal. The first scanning signal includes a plurality of scanning pulse signals in one period.
