Patent ID: 7271816

Claim:
A display apparatus comprising: a display device; said display device being of a type in which three light emitting elements for emitting three primary colors R, G, and B are aligned in a fixed order to form one pixel; a plurality of said pixels are aligned in a first direction to form one line; a plurality of said lines are aligned in a second direction, orthogonal to said first direction, to form a display screen; a luminance and chroma separating unit operable to input color information at pixel accuracy and to separate said color information into luminance data at pixel accuracy and chroma data at pixel accuracy; a sub-pixel luminance data generating unit operable to receive said luminance data at pixel accuracy and to generate luminance data at sub-pixel accuracy at one to one correspondence with said three light emitting elements forming one pixel; a luminance and chroma synthesizing unit operable to synthesize luminance data at sub-pixel accuracy and chroma data at pixel accuracy and to output color information at sub-pixel accuracy; and a display control unit operable to control each light emitting element of said display device by using color information from said luminance and chroma synthesizing unit and to perform display with said display device.
