Abstract
In a GOA circuit and a liquid crystal display panel provided by the present disclosure, by dividing GOA units in a GOA circuit into groups and cascading the GOA units in each group, and by successively outputting an enable signal to the first to kGOA units at preset time intervals by an enable signal output unit so that the GOA circuit successively outputs a scanning signal from a first group to a kgroup of GOA units, the number of cascades of GOA units is reduced, the signal attenuation is decreased, and the display effect of a liquid crystal display panel is thus improved.
