Abstract
The present disclosure provides a gate driver on array (GOA) circuit and a display panel. The GOA circuit includes multi-level cascaded GOA units. Each of the GOA units includes a pull-up control module, a pull-up module, a pull-down module, a pull-down maintenance module and a bootstrap capacitor. By sharing part of the circuit, each of the GOA units can realize multi-level scanning signal outputting, which simplifies the structure of the GOA circuit and further realizes a narrow frame design of display panels.
