Abstract
A Gate Driver on Array (GOA) circuit and a display panel are provided. The GOA circuit includes a plurality of cascaded GOA units. An Nth stage GOA unit includes a pull-up control circuit, a pull-up output circuit and a scan direction control circuit. The scan direction control circuit can be controlled by the clock signal to realize the alternating forward and backward scanning. The output terminal of the scan direction control circuit is connected with the output terminal of the pull-up control circuit, and the output terminal potential of the pull-up control circuit can be alternately changed.
