Patent ID: 8233007

Claim:
A display device for conducting a display operation using a number n of primary colors, where n is a natural number that is equal to or greater than four, the display device comprising: a video signal converting section arranged to receive an m-primary-color signal representing a number m of primary colors, where m is a natural number that is smaller than n, and arranged to convert the m-primary-color signal into an n-primary-color signal representing the n primary colors; and a pixel including multiple subpixels; wherein each of the multiple subpixels represents an associated one of the n primary colors; the n primary colors include a color that is complementary to a particular one of the m primary colors; and the video signal converting section is arranged to generate the n-primary-color signal such that if a color component representing the particular primary color of the m-primary-color signal has a negative level, the complementary primary color has an increased luminance and the other non-complementary primary colors have decreased luminances compared to a situation where the color component representing the particular primary color is zero and at least four of the subpixels included in the pixel are lit.
