Abstract
The present disclosure provides a shift register unit whose operating time includes a plurality of multi-frame periods, each of the multi-frame periods including a plurality of frame periods. The shift register unit includes a trigger signal input terminal, an input module, a pull-up module, a pull-down control module, a plurality of pull-down modules, and a signal output terminal. The pull-down control module is configured to sequentially provide active signals to the control terminals of respective pull-down modules in pull-down stages of respective frame periods of one multi-frame period. The present disclosure further provides a shift register, a gate driving circuit and a display panel. The shift register unit has longer lifetime and better electric performance, and can meet the requirements of high-reliability products.
