Abstract
A gate on array (GOA) circuit for used in an LCD includes GOA units connected in cascade. An Nth GOA unit includes an Nth stage-transmittance circuit, an Nth Q-node controlling circuit, an Nth P-node controlling circuit, an Nth outputting circuit, and a first switch circuit where N is a positive integer. The first switch circuit connected to the Nth scanning line, for inputting an enabling signal to the Nth scanning line before the LCD shows images so as to turn on a TFT in a pixel which the Nth scanning line is connected to. The benefit of the function is that the display does not leak electricity when the black screen is woken up and that the stability of the circuit is enhanced at the same time.
