Abstract

The present invention provides a gate driver on array (GOA) circuit and a display panel, in the GOA circuit, a nth one of GOA units has a pull-up control module, a logical addressing module, a pull-up module, first pull-down module, a second pull-down module, a first pull-down maintenance module connected to a first node, a second pull-down module, a third pull-down module, and a second pull-down maintenance module connected to a third node, and a logical addressing module. The logical addressing module pulls up a potential of a second node potential twice to facilitate increasing a threshold voltage margin.
