Abstract

Provided is a display device. The display device includes: a gamma mapping unit; a compensating signal generation unit including a limit gray scale determination unit outputting a white limit gray scale value; and a hue control compensation unit including a main color compensation unit and a white compensation unit. The white compensation unit decreases a gray scale value of the white image signal based on the white limit gray scale value to generate the white compensated signal and the main color compensation unit compensates the red, green and blue image signals based on the white limit gray scale value to generate the red, green and blue compensated signals, when gray scale value of the white image signal is larger than the white limit gray scale value.
