The present application provides a GOA circuit and a display panel. The GOA circuit includes a plurality of cascaded GOA units. Every GOA unit includes a pull-up control module, a pull-up output module, a pull-down control module, a pull-down output module, a pull-down maintenance module, and a random location module. By adding the random location module in the GOA unit, the GOA circuit has a function of randomly selecting rows and outputting scanning signals, so as to realize a purpose of randomly selecting rows for mobility detection and compensation.
