Abstract
The present disclosure provides to a shift register unit, a driving method, a gate driving circuit, and a display panel. The shift register unit includes: first and second signal terminals respectively outputting high and low levels alternately, a level logic of a signal output from the second signal terminal being opposite to that from the first signal terminal; first and second pull-down control circuits; a first pull-down circuit coupled to the first pull-down node, the first signal terminal, and a pull-down target node, and transmitting, in response to a signal of the first pull-down node, the signal of the first signal terminal to the pull-down target node; a second pull-down circuit coupled to the second pull-down node, the second signal terminal, and the pull-down target node, and transmitting, in response to a signal of the second pull-down node, the signal of the second signal terminal to the pull-down target node.
