Abstract
The embodiments of the present disclosure disclose a shift register unit and a method for driving the same, a gate driving circuit, and a display apparatus. The shift register unit includes: an input circuit configured to output an input signal from an input signal terminal to a pull-up node; an output circuit configured to output a clock signal from a clock signal terminal to an output signal terminal under control of a potential at the pull-up node; a resetting and de-noising circuit configured to reset and de-noise the pull-up node and the output signal terminal under control of a potential at a pull-down node; and a pull-down node control circuit coupled to a first voltage terminal and the pull-down node, and configured to electrically couple the pull-down node to the first voltage terminal under control of the potential at the pull-down node.
