    Abstract: The present disclosure discloses a shift register unit, a gate drive circuit, and a driving method thereof, and relates to the field of display technologies. The shift register unit includes an input sub-circuit, an output control sub-circuit, and an output sub-circuit. The input sub-circuit is coupled to a first node and a first voltage terminal, and is configured to output a first voltage signal to the first node in response to an input control signal. The output control sub-circuit is coupled to the first node, a second node, and a clock signal terminal, and is configured to output an output control signal to the second node in response to the first voltage signal and a clock signal. The output sub-circuit is coupled to the second node, a DC voltage terminal, and an output terminal, and is configured to output a DC voltage signal to the output terminal under the control of the output control signal.
