Abstract
A shift register, a method for driving the same, a gate driving circuit, and a display device are described. The shift register includes a pull-up control circuit which outputs the voltage of a signal input terminal, a pull-up circuit which outputs the voltage of a first clock signal input terminal, a pull-down control circuit which outputs the voltage of a second clock signal input terminal, or pulls down the voltage of the pull-down node, a pull-down circuit which pulls down voltages of the pull-up node and the signal output terminal to the first voltage terminal, respectively, a reset circuit which pulls down voltages of the pull-up node and the signal output terminal to the first voltage terminal, respectively, and a noise reduction control circuit which outputs the voltage of a noise reduction control signal terminal to the pull-down node in the blanking time of an image frame.
