Abstract: Disclosed is a GOA circuit, and the GOA circuit includes multiple stages of GOA unit circuits. Each stage of GOA unit circuit includes a first scan module, a first clock input module, a first signal port control module, a third signal port control module, a first output module, a first global signal operation module, a second scan module, a second clock input module, a second signal port control module, a fourth signal port control signal module, a second output module and a second global signal operation module. The afterimages that may occur when a power supply of a crystal display panel is abnormally cut off can be avoided by using the disclosed GOA circuit, and thus the user experience can be improved.
