Abstract
The present invention discloses a shifting register and an apparatus for driving gate lines, and it relates to Liquid Crystal Display technical field, for reducing the noise of a shifting register during non-working period. The shifting register comprises: a first thin film transistor, a second thin film transistor, a third thin film transistor, a fourth thin film transistor, a capacitor and a pull-down module, and the pull-down module is connected among a clock signal port, a first node and a signal output terminal, and further is connected to a low level signal terminal, for maintaining the first node and the signal output terminal to be at low level during the non-working period of the shifting register. The apparatus for driving gate lines comprises a plurality of above shifting registers connected in serial. The present invention is applicable to driving gate lines.
