Abstract
A GOA circuit and a liquid crystal device (LCD) are disclosed. The GOA circuit includes a plurality of GOA units and a control module. Each of the cascaded GOA units is configured for charging corresponding horizontal scanning lines within a display area when being driven by a first level clock, a second level clock, a first control clock, and a second control clock. After the horizontal scanning lines are fully charged by the GOA circuit, the control module is configured for resetting the gate driving signals to be at the first level, i.e., the invalid level, via the turn-on pulse signals and the negative-voltage constant-voltage source.
