Abstract
A shift register unit and a method for driving the same, a gate driving circuit, and a touch display apparatus are disclosed. The shift register unit includes: an input circuit configured to output an input signal received at an input signal terminal to a pull-up node; an output circuit configured to output a gate driving signal at an output signal terminal under control of a clock signal; a reset circuit configured to reset the pull-up node to a first level under control of a reset signal; a pull-down control circuit configured to control a level at the output signal terminal using the first level at a first level terminal under control of a control signal and the level at the pull-up node; and a compensation circuit configured to compensate for the level at the pull-up node using a compensation signal under control of the level at the pull-up node.
