Abstract
The invention provides a GOA circuit and driving method therefor, and a display panel. The GOA circuit includes a GOA unit. The GOA unit includes a forward and reverse scan control module, a node signal control module, a voltage regulator module, an output control module, a first pull-down module, and a second pull-down module. When the second pull-down module is in operation, the forward and reverse scan control module controls the voltage regulator module to be in an off state, so that the GOA circuit has no transistor in the on state for a long time, thus to suppress threshold voltage drift in transistors.
