Abstract
A gate drive circuit is disclosed. The gate drive circuit comprises multi-stage of GOA drive unit, and each stage of GOA drive unit comprises a signal afferent unit, used for outputting a pull-down control signal; an output unit, used for outputting a first gate signal and a second gate signal; a pull-up control unit, used for outputting a pull-up control signal; and a pull-up sustaining unit, used for pulling up an electric potential of the control end of the output unit to an electric potential of the direct-current power supply according to the pull-up control signal, so that the first gate signal and the second gate signal are maintained in a high-level state.
