Recent advances in color subpixel rendering theory have enabled the economical manufacture of very high resolution flat panels for full color natural image display. The theory has been extended to projectors using displaced color imaging light modulators, enabling higher resolution image reconstruction with no increase in modulator pixel elements. Displacing the projected pixel locations for each color allows additional degrees of freedom with which to reconstruct the image. The resulting increase in 'addressable points' allows high spatial frequencies at and just below the traditional Nyquist Limit to be reconstructed over the full positional phase space, without aliasing or phase error, increasing observable image quality. The Modulation Transfer Function Limit is extended, adding image detail. Examples of color subpixel rendering algorithms for both flat panel & projector displays, and resulting performance improvement are examined. Implications for Electronic Digital Cinema and HDTV are explored.
