Abstract
The present disclosure discloses a scan driving circuit of a liquid crystal display (LCD) panel, an LCD device and a driving method. The scan driving circuit of the LCD panel includes a time delay component. An input end of the time delay component is coupled to an output enable. An output end of the time delay component is coupled to a dock voltage pulse. A delay time of the time delay component is less than an action time of a single output enable cycle.
