WIPO Patent Application WO/2021/168952
Kind Code:
A1
Abstract:
The present application provides a GOA circuit and a display panel. The nth level GOA unit in the GOA circuit comprises: a pull-up control module, a logic addressing module, a pull-up module, a first pull-down module, a second pull-down module, and a first pull-down maintaining module which are connected to a first node; a second pull-down module, a third pull-down module, and a second pull-down maintaining module which are connected to a third node; and a logic addressing module. The logic addressing module pulls up the potential of a second node twice, facilitating the improvement of the threshold voltage margin.
