Abstract
The present invention provides a GOA circuit, comprising a forward-backward scan control module, an output module, an output pull-down module, a node control module, a second node signal input module, a second node signal control module, a voltage stabilizing module and a second capacitor; the forward scan of the circuit is controlled with the ninth and the tenth thin film transistors, and the signal input of the second node is controlled with the first and the eleventh thin film transistors, and the mutual control of the first node and the second node are achieved with the second, the fourth and the fifth thin film transistors, and meanwhile, as the GOA circuit applies to a display of dual side drive interlaced scan structure, the GOA circuits of the two sides can respectively receive four different clock signals to reduce the loading of the signal line of the GOA circuit.
