Abstract
A voltage control circuit, a shift register unit, and a display device are provided. The voltage control circuit is applied to a shift register unit, the shift register unit includes a gate-driving-signal output end, and the voltage control circuit includes a discharge control end, a discharge circuit and a discharge voltage end. The discharge circuit is configured to, under control of a signal inputted by the discharge control end, control to electrically disconnect the gate-driving-signal output end from the discharge voltage end during a display period of a display screen, and control to electrically connect the gate-driving-signal output end to the discharge voltage end during a shutdown period of the display screen.
