Abstract: A high contrast high resolution display is produced using an image chain comprising a plurality of downstream high resolution modulators. The modulators may be illuminated by a locally dimmed backlight. Polarization control is maintained throughout the image chain via reference and analyzing polarizers combined with non-depolarizing layers. The modulators are grayscale and modulate at the sub- pixel level. A color panel may be maintained for embodiments that require color. Diffusion in the chain is matched to a resolution of the image content carried in the light such that the effects of local dimming and sub-pixel resolution are preserved. Brightness enhancement films may be utilized to enhance brightness and maintain polarization control.
