Abstract: The present disclosure provides a shift register unit and a driving method therefor, a gate drive circuit, and a display device, belonging to the field of display technologies. In the shift register unit, a first input circuit can control a potential of a first node under control of a first clock signal provided by a first clock terminal and control a potential of a third node under control of a potential of a second node. A second input circuit can control the potential of the second node under control of the first clock signal, an input control signal provided by an input control terminal, the potential of the third node, and the potential of the first node. An output circuit can transmit a pull-up power signal at a high potential or a pull-down power signal at a low potential to an output terminal under control of the third node. In this way, the potential of the output terminal can be reliably controlled only by flexibly setting clock signals provided by two clock terminals and the input control signal provided by the input control terminal. The control process is simple, and the control flexibility is high.
