Patent ID: 7038673

Claim:
A liquid crystal display (LCD) comprising: a timing controller for receiving external image data, and outputting a vertical sync start signal based on a data-enable signal having an irregular output interval to control output of the image data, the vertical sync start signal having a generation interval associated with a blank interval of the data-enable signal; a data driver for converting the image data and outputting the same; a gate driver for sequentially applying both a first gate-on voltage and a second gate-on voltage to a same gate line, wherein the first gate-on voltage is to drive a previous line being most adjacent to and having the same polarity as a present line, and the second gate-on voltage is to drive the present line; and an LCD panel being first charged with the first gate-on voltage supplied from the gate driver, and second charged with the second gate-on voltage, wherein the LCD panel displays the image data received from the data driver during the second charging.
