Title:
SHIFT REGISTER CIRCUIT, DRIVING METHOD, GATE DRIVE CIRCUIT, AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/042189
Kind Code:
A1
Abstract:
A shift register circuit, a driving method, a gate drive circuit, and a display device are provided. The shift register circuit comprises a clock signal adjustment circuit (13) and a self-controlled conduction circuit (14). The clock signal adjustment circuit (13) has a first clock signal input (CLK), a second clock signal input (CLKB), and a clock signal adjustment output (CLKR). The clock signal adjustment circuit (13) is used to output a first level by means of the clock signal adjustment output (CLKR) if a first clock signal and a second clock signal are both at a second level. The self-controlled conduction circuit (14) is used to control the clock signal adjustment output (CLKR) to be electrically connected to a pull-up node (PU) if the pull-up node (PU) is at the first level, or break the electrical connection between the clock signal adjustment output (CLKR) and the pull-up node (PU) if the pull-up node (PU) is at the second level.
