Abstract
Disclosed is a GOA circuit. By locating the thirteenth thin film transistor (T13) coupled with the tenth thin film transistor (T10) in series and controlled by the Mth clock signal (CK(M)) in the output module (400) of the nth stage GOA unit, as entering signal interrupt and performing touch scan, the output competition of the output ends (G(n)) can be prevented; by locating the twelfth thin film transistor (T12) controlled by the global control signal (Gas) in the output end pull-down module (600), and by setting the composite signal (CS) to be the pulse signal consistent with the touch scan signal as entering signal interrupt and performing touch scan, the twelfth thin film transistors (T12) of the GOA units of all stages can be activated, and the output ends of the GOA units of all stages outputs the composite signal (CS) consistent with the touch scan signal (TP).
