摘要: A display device includes pixels which represent first, second and third colors and white, a signal controller which operates a white initial luminance value of the white and first, second and third luminance compensation values of the first, second and third colors based on input image signals of the first, second and third colors, generates a white output image signal of the white based on a sum of at least one portion of the first, second and third luminance compensation values and the white initial luminance value, and generates first, second and third output image signals of the first, second and third colors based on remaining first, second and third luminance compensation values, and a data driver which converts the white output image signal and the first, second and third output image signals into data voltages and supplies the data voltages to the pixels to display an image.

摘要: One or more embodiments of the present invention relate to a four color image display device. A display device according to an exemplary embodiment of the present invention includes a first pixel adapted to display a first color, a second pixel adapted to display a second color, a third pixel adapted to display a third color, and a white pixel adapted to display a first white. In one aspect, the first to third pixels are adapted to display a second white in combination, and a ratio of the first white and the second white varies according to a gray. Accordingly, a greenish phenomenon of a low-luminance white light in a four color display device may be reduced.
