Abstract
A shift register unit, a gate driving circuit, a display device, and a driving method are disclosed. The shift register unit includes a first sub-circuit, a second sub-circuit, a leakage prevention circuit and a blanking input sub-circuit, wherein the first sub-circuit comprises a first input circuit and a first output circuit; the second sub-circuit comprises a second input circuit and a second output circuit; the leakage prevention circuit is configured to control a level of a leakage prevention node under control of the level of the first node, so as to turn off a circuit connected between the first node and the leakage prevention node; and the blanking input sub-circuit is connected to the first node and the second node, and is configured to receive a selection control signal and a first clock signal, and control the level of the first node and the level of the second node.
