Abstract
A gate driver on array (GOA) circuit and a display panel is provided. The GOA circuit includes a plurality of cascading GOA units. A current stage of the GOA units includes: a pull-up module, a pull-up control circuit unit, and a selection module. The pull-up module includes a first transistor. A source of the first transistor is connected to the selection module, a gate is connected to the pull-up control module through a first node, and a drain is configured to output a scan signal of the current stage. The selection module is configured to receive a first control signal and a second control signal to control the clock signal to transmit to the source of the first transistor.
