Abstract
The present disclosure provides a GOA circuit and a display panel, wherein the GOA circuit is provided with a second pull-down control circuit unit (). Combined with a timing diagram, during a touch period, for a gradual transmission first node (Q), through a third control signal (GAS) and a second control signal (DU), the first node (Q) changes from a low-level signal to a high-level signal, so that two leakage paths of the first node (Q) disappear, and there is no leakage path at the first node Q during touch, thereby maintaining stability of the first node Q.
