Patent ID: 7847805

Claim:
A display apparatus including pixels, each pixel configured to display four colors including three primary colors and a white color, the display apparatus receiving chrominance signals corresponding to a mixing ratio of said four colors and displaying said chrominance signals to include said four colors, comprising: a color correction instrument which applies, to at least one of the pixels, each of a) a first color correction of increasing saturation of at least one of said chrominance signals by decreasing a value of the at least one of said chrominance signals to form a first corrected chrominance signal and b) a second color correction of increasing the white color component of the at least one of said chrominance signals by increasing the value of the at least one of said chrominance signals to form a second corrected chrominance signal, when a predetermined color component is detected in said chrominance signals corresponding to said at least one pixel; a height generation instrument which generates, when a region of adjacent pixels having said predetermined color component is detected, a saturation height difference for the pixels in said region by assigning each of said first corrected chrominance signal and said second corrected chrominance signal to the pixels of said region according to a predetermined assignment pattern, the predetermined assignment pattern alternating said first and second corrected chrominance signals over one or more of said pixels; and a display instrument which displays the pixels of said region using said generated saturation height difference.
