Patent ID: 8570254

Claim:
A display apparatus comprising: multiple pixels each including sub-pixels of red, green, blue and white; and a color operation circuit for converting an image signal inputted from the outside of the display apparatus into the inside of the display apparatus into a driving signal for the sub-pixels, wherein each of the sub pixels includes an electroluminescence device, wherein the color operation circuit adjusts a luminance ratio between the sub-pixels of red, green and blue and the sub pixel of white based on a display region determination signal, which represents display position information of an icon display region, is inputted from the outside of the display apparatus, and is synchronized with the image signal, and wherein during performing gray scale display other than black, the color operation circuit makes a larger than zero luminance ratio of each of red, green, and blue when the display region determination signal represents the icon display region, and the color operation circuit makes a zero luminance ratio of each of red, green, and blue when the display region determination signal represents a natural image display region.
