SHIFT REGISTER UNIT AND GATE DRIVE APPARATUS

摘要

A shift register unit and a gate drive apparatus are disclosed. The shift register unit comprises a pre-charge module configured to provide a voltage of a first voltage source to a first node under the control of an input signal from the signal input terminal, the first node being an output node of the pre-charge module; a pull-up module, and configured to provide a clock signal from a first clock signal terminal to a signal output terminal under the control of a voltage of the first node; a reset module configured to provide a voltage of a second voltage source to the first node under the control of an input signal from a reset signal terminal; and a pull-down module configured to maintain the first node and the signal output terminal at a low level during non-operating time of the shift register unit.
