ABSTRACT:
An image display device includes a display panel having pixels, and a signal compensate unit for receiving first, second and third image signals externally provided, and for generating a first compensate signal obtained from the first and second image signals. The signal compensate unit generates a second compensate signal obtained from the first compensate signal and the first and third image signals. The image display device also includes a data driver for receiving the second compensate signal from the signal compensate unit, and for generating data voltages corresponding to the second compensate signal to the pixels of the display panel. A method for compensating image signals includes recognizing first, second and third image signals at three successive frames, obtaining a first compensate signal from the first and second image signals, obtaining a second compensate signal from the first and third image signals and the first compensate signal, and providing the second compensate signal to pixels of a display panel.
