Abstract
A shift register unit, a method of driving a shift register unit, a gate driving circuit and a touch display device are disclosed. The shift register unit includes a first signal input terminal, a first voltage control terminal, a second signal input terminal, a second voltage control terminal, a signal output terminal, a first voltage terminal, and a second voltage terminal. The shift register unit further comprises a first input circuit, a second input circuit, an output circuit, an anti-leakage circuit, a first control circuit, and a second control circuit. The anti-leakage circuit is configured to bring a first node into conduction with a second node in response to an active potential of the second voltage terminal.
