Abstract
A liquid crystal display includes an image signal modifier for generating a modified signal based on a first image signal of a first frame, a second image signal of a second frame, and a lookup table. A data driver converts the modified signal into a data voltage which is supplied to a pixel of the display. The lookup table stores a plurality of reference modified signals for a plurality of reference first image signals and a plurality of reference second image signals. The lookup table includes a first lookup table having a gray gap of the reference first image signals and a gray gap of the reference second image signals of x, and a second lookup table having a gray gap of the reference first image signals and a gray gap of the reference second image signals of y, where y is greater than x.
