摘要：
A gate-driver-on-array circuit. The gate-driver-on-array circuit contains several GOA circuit units (12). Each level of GOA circuit units (12) contains an input control module (100), an output control module (200), a pull-down module (300) and a pull-up maintaining module (400). The input control module (100) comprises a first transistor (T1), a second transistor (T2), a third transistor (T3) and a fourth transistor (T4). Each level of GOA circuit units (12) is constituted by ten transistors, and the number of used transistors is relatively small, so that the beneficial effect of facilitating a narrow-frame display design is achieved. In addition, the input control module (100) of the GOA circuit units contains the second transistor (T2) and the third transistor (T3) controlled by a first gate-on signal (Gas1). Since the first transistor (T1) and the second transistor (T2) are connected in series, and the third transistor (T3) and the fourth transistor (T4) are connected in series, a leakage current can be re
