Title:
SHIFT REGISTER CIRCUIT, DRIVING METHOD, AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/134367
Kind Code:
A1
Abstract:
A shift register circuit, a driving method, and a display device. The shift register circuit comprises a noise reduction sub-circuit (50) and a pull-down node control sub-circuit (10); a control end of the noise reduction sub-circuit (50) is connected to a pull-down node (PD); the noise reduction sub-circuit (50) is connected to a first voltage input end; the pull-down node control sub-circuit (10) comprises a first pull-down node control sub-circuit (101) and a second pull-down node control sub-circuit (102); the second pull-down node control sub-circuit (102) is configured to control a pull-down control node (NET1) to be connected to a first clock signal (CLK1) input end when the first clock signal (CLK1) input end inputs a first level, and control the pull-down node (PD) to be connected to the first clock signal (CLK1) input end when the potential of the pull-down control node (NET1) is the first level, so that the potential of the pull-down node (PD) is the first level, thereby controlling noise reduction transistors (M2, M7) comprised in the noise reduction sub-circuit (50) to be switched off.
