SHIFT REGISTER UNIT AND DRIVING METHOD THEREFOR, GATE DRIVING CIRCUIT, AND DISPLAY DEVICE

WIPO Patent Application WO/2019/242317

A1

A shift register unit (10) and a driving method therefor, a gate driving circuit (20), and a display device (30). The shift register unit (10) comprises an input circuit (100), an output circuit (200), a first reset circuit (300), and a reset control circuit (400). The input circuit (100) is configured to control the level of a first node (PU) in response to an input signal. The output circuit (200) is configured to output a clock signal (CLK) to an output terminal (OT) under the control of the level of the first node (PU). The first reset circuit (300) is configured to reset the first node (PU) in response to a first reset signal (Re1). The reset control circuit (400) is configured to input the first reset signal (Re1) to the first reset circuit (300) in response to a reset control signal and a reference signal, in order to turn on the first reset circuit (300). The shift register unit (10) can solve the problem of insufficient noise reduction of the first node (PU) due to the reduction of channel current of a transistor in a low temperature environment, thereby avoiding repeated output and ensuring the normal operation of the product.
