Abstract
Disclosed is a GOA driving circuit. In screen awakening stage, the first global control signal (Gas) controls the twelfth thin film transistor (T) to be activated for realizing the All Gate On function, and meanwhile controls the eleventh thin film transistor (T) to be activated to pull down the voltage level of the second node (P(n)); in reset stage, the reset signal (Reset) controls the first thin film transistor (T) to reset the voltage level of the second node (P(n)), and to set the duration of the single pulse of the reset signal (Reset) to be at least the sum of durations of initial pulses of the first, second clock signals; in touch scan stage, the second global control signal (Gas) controls the thirteenth thin film transistor (T) to be activated to make the output ends of the GOA units of the respective stages output composite signals (CS).
