Title: GOA CIRCUIT
Abstract:
Disclosed is a GOA circuit. The GOA circuit comprises a plurality of cascaded GOA circuit units, wherein n is a natural number greater than 0, and the nth stage of the GOA circuit unit includes a first thin film transistor (T1), a second thin film transistor (T2), a third thin film transistor (T3), a fourth thin film transistor (T4), a fifth thin film transistor (T5), a sixth thin film transistor (T6), a seventh thin film transistor (T7), an eighth thin film transistor (T8), a ninth thin film transistor ( T9), a first capacitor (CI), and a second capacitor (C2). On the basis of the prior GOA circuit, the GOA circuit enables the conduction between a first node and a second node to be achieved by means of a parallel connection of the eighth thin film transistor and the ninth thin film transistor, a gate terminal of the eighth thin film transistor being connected to a second node of a previous stage, and a gate terminal of the ninth thin film transistor being connected to a second node of a subsequent stage. In addition to the function of preventing stress severity of the seventh thin film transistor in the prior GOA circuit, the GOA circuit can prevent unstable output of the output terminal.
