An n-th GOA unit includes an output control module, a forward/backward scanning control module, a node signal control module, a second pull-down circuit, a first pull-down circuit and a pull-up circuit. The forward/backward scanning control module control the GOA circuit to perform a forward or a backward scanning. The output control module controls an output of an n-th gate driving signal. The first pull-down circuit comprises a seventh thin film transistor. The second pull-down circuit comprises a fifth thin film transistor. The node signal control module control the fifth thin film transistor. The pull-up circuit includes an eighth thin film transistor. After the LCD panel is powered off, the second global control signal becomes a low level. This invention can eliminate a ghost image in the LCD panel when electricity is powered off, and improve user experience."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"GOA circuit","description":"This invention provides a GOA circuit comprising m cascaded GOA units.
