Abstract
(EN)
Disclosed are a shift register unit, a gate drive circuit, and a display panel and a drive method thereof. The shift register unit comprises: a detection signal input sub-circuit (110), a display signal input sub-circuit (120), an output circuit (130), a pull-down control circuit (140) and a signal output end (OUT<N>), wherein the output circuit (130) comprises a pull-up sub-circuit (131) and a pull-down sub-circuit (132), and the pull-down control circuit (140) comprises a selection sub-circuit (141) and multiple pull-down control sub-circuits (142, 143). The shift register unit has a simple structure and a relatively long life.
