Abstract
A shift register unit and a method for driving the same, a gate driving circuit, and a display apparatus are disclosed. The shift register unit includes: an input circuit configured to transmit an input signal to a pull-up node; an output circuit configured to transmit a clock signal to an output signal terminal under control of a voltage at the pull-up node; a first reset circuit configured to reset the pull-up node to a first level under control of a first reset signal; a first pull-down control circuit configured to control levels at the pull-up node and the output signal terminal under control of a first control signal; and a first voltage control circuit electrically connected to a second control signal terminal, and configured to control a voltage signal waveform at the first pull-down node under control of a second control signal.
