Claim:
1. A display device, comprising: a first pixel including only three sub-pixels to emit red, green, and white light, respectively; a second pixel neighboring the first pixel, the second pixel including only three sub-pixels to emit blue, green, and white light, respectively, wherein the display device includes only two kinds of pixels including the first pixel and the second pixel; and a color data converter to: receive first input color data corresponding to the first pixel and second input color data corresponding to the second pixel, and generate first output color data each corresponding to red (R), green (G), and white (W) sub-pixels included in the first pixel and second output color data each corresponding to blue (B), green (G), and white (W) sub-pixels included in the second pixel, wherein each of the first input color data and the second input color data includes red, green, and blue input color data, wherein the first output color data for the red (R) sub-pixel is generated based on a first sum of a value obtained by multiplying the red input color data of the first input color data by a first weight and a value obtained by multiplying the red input color data of the second input color data by a second weight, wherein the second output color data for the blue (B) sub-pixel is generated based on a second sum of a value obtained by multiplying the blue input color data of the second input color data by the first weight and a value obtained by multiplying the blue input color data of the first input color data by the second weight, and wherein the first and second weights are 0.5, and wherein the color data converter is to: determine first white output color data by extracting a minimum value from the first input color data and multiplying the extracted minimum value by a first gain ratio, determine second white output color data by extracting a minimum value from the second input color data and multiplying the extracted minimum value by a second gain ratio, calculate the red output color data of the first output color data by subtracting a value obtained by multiplying the first white output color data by the first weight and a value obtained by multiplying the second white output color data by the second weight from the first sum, and calculate the blue output color data of the second output color data by subtracting a value obtained by multiplying the second white output color data by the first weight and a value obtained by multiplying the first white output color data by the second weight from the second sum.
