Abstract:
1. A method of compensating for a kick-back voltage, the method comprising: 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, wherein the kick-back correction function is set such that the input pixel data is multiplied by a scale constant having a value between 0 and 1 and then twice the kick-back voltage is added to the multiplication result as an offset value to generate corrected pixel data for pixels to which a positive pixel signal is applied, and the input pixel data is multiplied by the scale constant to generate corrected pixel data for pixels to which a negative pixel signal is applied.
