Abstract
The present disclosure provides a shift register unit and a method for driving the same, a gate driving circuit and a display device. The shift register unit includes: an input sub-circuit configured to receive an input control signal and an input signal, and transmit the input signal to a first pull-down node of the shift register unit under control of the input control signal; a first control sub-circuit configured to receive a first clock signal and electrically couple the first pull-down node to a second pull-down node of the shift register unit under control of the first clock signal; and an output sub-circuit configured to receive a first constant voltage signal and transmit the first constant voltage signal to an output terminal of the shift register unit under control of a voltage at the second pull-down node.
