1. A gate drive circuit, comprising:
drive units, wherein each of the drive units comprises cascaded shift registers; wherein each of the shift registers comprises an input sub-circuit, a first reset sub-circuit and an output sub-circuit;
wherein the input sub-circuit is connected with a first cascaded input end and a first node, and is configured to control an electric potential of the first node under control of an electric potential of the first cascaded input end; the output sub-circuit is configured to control an electric potential of a signal output end under control of the electric potential of the first node; the first reset sub-circuit is connected with the first node and a second cascaded input end, and is configured to reset the first node under control of an electric potential of the second cascaded input end;
wherein the first cascaded input end of a first shift register of each of the drive units is connected to a different start signal end; one or more drive units in the drive units comprise a reset control sub-circuit, wherein the reset control sub-circuit is connected with the second cascaded input end of a last shift register and one or more start signal ends, and is configured to control an electric potential of the second cascaded input end of the last shift register according to an electric potential of the one or more start signal ends; the start signal end connected with the first cascaded input end of the first shift register in one of the one or more drive units is different from the one or more start signal ends connected with the reset control sub-circuit in the one of the one or more drive units.
