| 1. A method of driving a liquid crystal display, comprising:
receiving and registering first source data for display by a liquid crystal cell of a liquid crystal panel during a first
frame period;
receiving second source data for display by the liquid crystal cell during a second frame period subsequent to the first frame
period;
generating modulated data according to a comparison result between the registered first source data and the second source
data;
supplying the modulated data to a pixel electrode of the liquid crystal cell of during an initial portion of an output period
for applying data to the pixel electrode of the liquid crystal cell; and
applying data different from the modulated data to the pixel electrode of the liquid crystal cell of the liquid crystal panel
at a later portion of the output period than the initial portion.
