Abstract
A data clipping method using red, green, blue and white data, and a display device using the same are disclosed. Red (R), Green (G), Blue (B), and White (W) data are modulated by multiplying clipped data of an input image by a gain, a luminance increment is created based on the result of subtracting the clipped data from the modulated RGB data, and the luminance increment is added to the W data to be written to a W sub-pixel.
