Title:
SHIFT REGISTER AND DRIVING METHOD THEREOF, GATE DRIVING CIRCUIT AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/040711
Kind Code:
A1
Abstract:
A shift register and a driving method thereof, a gate driving circuit and a display device. The shift register comprises: an input unit (11), configured to provide an input signal to a first node (N1); a pull-up unit (12), configured to provide a voltage of a first power voltage terminal (VGH) to an output terminal (OUTPUT); a pull-up control unit (13), configured to provide a voltage of the first power voltage terminal (VHG) or a second power voltage terminal (VGL) to a second node (N2); a pull-down unit (14), configured to provide a third clock signal (CK3) to the output terminal (OUTPUT); a pull-down control unit (15), configured to provide a voltage of the first power voltage terminal (VGH) to the first node (N1); a first noise reduction unit (16), configured to reduce electrical leakage of the input unit (11) with respect to the first node (N1) by means of adjusting a voltage at a third node (N3); and a second noise reduction unit (17), configured to reduce electrical leakage of the pull-down control unit (15) with respect to the first node (N1) by means of adjusting a voltage at a fourth node (N4). The invention reduces noise at the output terminal (OUTPUT) and increases driving capability.
