SHIFT REGISTER AND A GATE DRIVING DEVICE

摘要

The present invention discloses a shift registor and a gate driving device, the shift register comprising: an input module for providing an input signal to a pull-up node; an output module for storing the input signal and providing a first clock signal to an output terminal; a reset module for providing a level signal to the pull-up node; a pull-up module for providing a second clock signal to a pull-down node; a first pull-down module for providing the level signal to the pull-down node; and a second pull-down module for providing the level signal to the pull-up node and providing the level signal to the output terminal.
