Abstract

A shift register unit, a driving method and a gate driving circuit are provided. The shift register unit includes a pull-up node control circuit, a pull-down node control circuit, a capacitor circuit, an output circuit and a noise reduction adjustment circuit. The noise reduction adjustment circuit is connected to a pull-down node and a first level input end, and configured to reduce an increasing rate of a potential at the pull-down node within a noise reduction time period of a maintenance phase, and reduce a decreasing rate of the potential at the pull-down node within a non-noise-reduction time period of the maintenance phase.
