Title: GOA CIRCUIT AND LIQUID CRYSTAL DISPLAY
Abstract:
A GOA circuit and a liquid crystal display. The GOA circuit comprises multiple cascaded GOA units (11) and a control module (12). Each GOA unit (11) is used for being driven by a first level-transfer clock (CK-A1), a second level-transfer clock (CK-A2), a first control clock (CK-B1), a second control clock (CK-B1) into charging a corresponding horizontal scan line in a display area. The control module (12) is used for controlling, when all of the horizontal scan lines are concurrently charged by the GOA circuit, a gate driving signal to reset to a first potential, which is an invalid potential, via a start pulse signal (STV) and a negative-voltage constant power supply (VGL).
