Patent ID: 7671855

Claim:
A method for driving an LCD that includes an LCD panel having a plurality of data lines and gate lines, which charges a specific pixel by ( 1 ) first charging the data of an pixel adjacent to the specific pixel and having the same polarity as the specific pixel to change the polarity of the corresponding pixel, and ( 2 ) second charging the data of the specific pixel, the method comprising: (a) receiving image data from an external image signal source and a data-enable signal for controlling output of the image data; (b) checking whether the data-enable signal has been received, sequentially recording the image data on a predetermined number of built-in memories upon receiving the data-enable signal, sequentially extracting the recorded image data, and generating an internal data-enable signal upon extraction of the image data to output a vertical sync start signal having a generation interval associated with a blank interval of the data-enable signal; (c) applying a voltage corresponding to the image data to the data lines; and (d) sequentially applying both a first gate-on voltage and a second gate-on voltage based on the vertical sync start signal, wherein the first gate-on voltage drives a previous line being most adjacent to and having the same polarity as the present line, and the second gate-on voltage drives the present line.
