Abstract:
A GOA circuit and a display panel according to an embodiment of the present disclosure include multi-stage cascaded GOA units. Each GOA unit includes a pull-up control module, an output module, a stage transfer module, a pull-down module, and a pull-down maintenance module. The GOA circuit has a simple structure and can reduce a space occupied by a circuit layout while ensuring the circuit function. Therefore, an aperture ratio of the display panel is increased, and requirements for a narrow frame and a high resolution for the display panel are met.
