Abstract
Color sub-pixel display is performed with a display device that has three light emitting elements for emitting three primary colors R, G, and B, respectively, aligned in an x-y matrix. Color information at pixel accuracy is separated into luminance data at pixel accuracy and chroma data at pixel accuracy. From the luminance data at pixel accuracy, luminance data at sub-pixel accuracy is generated. The luminance data at sub-pixel accuracy and chroma data at pixel accuracy are synthesized, whereby color information at sub-pixel accuracy is obtained.
Claims11
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;
- luminance and chroma separating means for inputting color information at pixel accuracy and separating said color information into luminance data at pixel accuracy and chroma data at pixel accuracy;
- sub-pixel luminance data generating means for receiving said luminance data at pixel accuracy and generating luminance data at sub-pixel accuracy at one to one correspondence with said three light emitting elements forming one pixel;
- luminance and chroma synthesizing means for synthesizing luminance data at sub-pixel accuracy and chroma data at pixel accuracy and outputting color information at sub-pixel accuracy;
- and
- display control means for controlling each light emitting element of said display device by using color information from said luminance and chroma synthesizing means and performing display with said display device.
