Patent Images
1. A display device comprising:
- a plurality of pixels which individually display one of a first color, a second color, a third color, and white;
a signal processor which receives input image signals corresponding to the first to third colors, modifies color temperatures represented by the input image signals, compensates luminances of the input image signals, and converts the input image signals corresponding to the first to third colors into output image signals corresponding to the first to third colors and white as a result of the modification and compensation; and
a data driver which converts the output image signals into data voltages and supplies the data voltages to the pixels.

14. A method of driving a display device, the method comprising:
-
receiving red, green and blue input image signals; generating preliminary luminance signals based on the input image signals; modifying color temperatures of the preliminary luminance signals, and compensating luminances of the preliminary luminance signals to generate modification luminance signals of red, green, blue, and white; and generating output image signals of red, green, blue and white based on the modification luminance signals, wherein the luminance compensation of the preliminary luminance signals is performed based on the number of modification luminance signals of a previous frame having a luminance more than or equal to a maximum luminance of the display device. - View Dependent Claims (15, 16)
