Abstract
An object of the invention is to convert input RGB data to R'G′B′W data without suffering loss of gradations of the input RGB data. A display panelis configured having unit pixels made up of subpixels of RGBW (red, green, blue, white). In an RGB→R′G′B′W conversion section, conversion is carried out under conditions that usage rate of W is less than 100%, and a bit width of input RGB data us larger than a bit width of R′G′B′W data after conversion. In the RGB→R′G′B′W conversion section, R1G1B1values and W values are determined so that an absolute value of a sum of values obtained by multiplying differences between respective RGB data input and respective RGB components in R′G′B′W data after conversion by a weight, becomes minimum.
