Title:
SHIFT REGISTER UNIT, GATE DRIVING CIRCUIT AND DRIVING METHOD THEREFOR, AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/185590
Kind Code:
A1
Abstract:
A shift register unit, a gate driving circuit (130) and a driving method therefor, and a display device (100). The shift register unit has a duty cycle comprising an input phase (t1), an output phase (t2), a resetting phase (t3), and a holding phase (t4). During the resetting phase (t3), a clock signal (CLK) is transmitted to an output terminal to pull down the voltage of the output terminal to a reference voltage (Vref1), and then the pulled-down voltage of the output terminal is changed from the reference voltage (Vref1) to a gate turn-off voltage (Vref2). During the holding phase (t4), the voltage of the output terminal is held at the gate turn-off voltage (Vref2). The reference voltage (Vref1) is less than the gate turn-off voltage (Vref2).
