ABSTRACT:
A method and apparatus of compensating for a kick-back voltage to reduce the generation of flicker in a liquid crystal display (LCD). The method of compensating for a kick-back voltage includes correcting input pixel data using a kick-back correction function that meets a condition on which a response characteristic of a voltage detected from a pixel electrode of a liquid crystal cell for a positive input pixel signal and a response characteristic of a voltage detected from the pixel electrode of the liquid crystal cell for a negative input pixel signal become symmetrical without causing a saturation state on a basis of a kick-back voltage measured from an LCD panel to generate corrected pixel data, and driving the LCD panel using the corrected pixel data.
