Abstract

A gate drive circuit, a control method thereof, and a display device are disclosed. The gate drive circuit includes a plurality of cascaded shift registers, and at least one coded control sub-circuit; wherein each stage of the shift registers is configured to transmit a received signal to a next stage of the shift registers and the coded control sub-circuit. The coded control sub-circuit is configured to receive a coded signal, and transmit a voltage at the first voltage terminal or the second voltage terminal to the drive signal output terminal according to a signal output from a shift register coupled to the control sub-circuit under the control of the coded signal.
