Abstract
A liquid crystal display and a pre-charging method thereof for pre-charging data lines using a ESD circuit to simplify a circuit configuration are provided. In the method, video lines receiving video signals are floated in a pre-charge interval of time. A pre-charge voltage is supplied to the video lines floated via a static electricity proof circuit connected to the video lines. The pre-charge voltage on the video line is pre-charged by a demultiplexer for making a time-divisional driving of the data lines in a video charge interval of time.
