Document Type and Number:
WIPO Patent Application WO/2017/206542
Kind Code:
A1
Abstract:
Provided are a shift register and an operation method therefor, a grid drive circuit, and a display device. The shift register comprises: an input module (11), wherein a first end thereof is connected to an input end (INPUT) of the shift register and is used for receiving an input signal from the input end (INPUT), a second end is connected to a first clock signal end (CLK1), and a third end is connected to a first node (P1); a pull-up module (12), wherein a first end thereof is connected to a first power supply voltage end (VGH), a second end is connected to a second node (P2), and a third end is connected to an output end (OUTPUT); a pull-up control module (13), wherein a first end thereof is connected to the first clock signal end (CLK1), a second end is connected to a second supply voltage end (VGL), a third end is connected to the second node (P2), and a fourth end is connected to the first node (P1); an output module (14), wherein a first end thereof is connected to the first node (P1), a second end is connected to a second clock signal end (CLK2), and a third end is connected to the output end (OUTPUT); and a noise reduction module (15), wherein a first end thereof is connected to the second node (P2), a second end is connected to the second clock signal end (CLK2), a third end is connected to the first supply voltage end (VGH), and a fourth end is connected to the first node (P1). The noise of the output end can be effectively reduced.
