Abstract
A shift register unit, drive method thereof, gate drive device and display device. The shift register unit includes: an input subcircuit; a reset subcircuit; an output subcircuit configured to provide a clock signal at a clock signal end to a current stage shift register unit output end in response to a voltage signal at the pull-up node and a control signal having a first voltage level, and to disable an output at the current stage output end in response to the control signal having a second voltage level; a pull down control subcircuit configured to provide a second voltage signal having a low voltage level to a pull-down node in response to the voltage signal at the pull-up node, and to provide the voltage signal having a high voltage level to the pull-down node in response to the voltage signal having a high voltage level; and a pull down subcircuit.
