Abstract

Disclosed is a shift register unit, a gate driving circuit and a driving method, as well as a display apparatus. The shift register unit has a working cycle including an input phase, an output phase, a reset phase and a maintaining phase. In the reset phase, a clock signal is transmitted to an output terminal to pull a voltage of the output terminal down to a reference voltage, and the pulled-down voltage of the output terminal is subsequently changed from the reference voltage to a gate-off voltage. In the maintaining phase, the voltage of the output terminal is maintained at the gate-off voltage. The reference voltage is smaller than the gate-off voltage.
