Patent ID: 8773340

Claim:
A color display apparatus for displaying a color image, comprising: a color conversion circuit configured to convert a three-color video signal into a n-color video signal (n≧4), the three-color video signal representing at least a first color component, a second color component and a third color component, and the n-color video signal representing at least the first color component, the second color component and the third color component; and a display panel including n-color pixels corresponding to n colors of the n-color video signal, the color image being made up of the n colors; wherein the three-color video signal includes three pixel color values, the first color component and the second color component of the three-color video signal are represented by at least one of the three pixel color values, and the third color component of the three-color video signal is represented by at least two of the three pixel color values, the n-color video signal includes n pixel color values, the first color component, the second color component and the third color component of the n-color video signal are represented by at least one of the n pixel color values, and in a case where the third color component is reproduced by the display panel, an output luminance of the third color component represented by the n-color video signal is higher than an input luminance of the third color component represented by the three-color video signal.
