Abstract
A shift register unit, a gate drive circuit, a display device and a method of driving a gate drive circuit are provided. The shift register unit includes a shift register circuit and an output control circuit. The shift register circuit is configured to output a valid output level at a first output terminal according to a first input signal received by a first input terminal, and is configured to reset according to a first reset signal received by a first reset terminal. The output control circuit is configured to output an invalid output level at the second output terminal according to a second input signal received by the second input terminal, thereby controlling a level of the first output terminal to the invalid output level, and is configured to reset according to a second reset signal received by the second reset terminal.
