D-ILA modulators and projectors based on LCOS (liquid crystal on silicon) technology have been developed. The compact reflection-mode modulators have resolution of up to 2048 x 1536 pixels for projection display applications. Research projectors have demonstrated resolution of 3840 x 2048 pixels. D-ILA projectors feature high contrast and a close-spaced pixel structure that creates high quality imagery. The structure of the D-ILA will be reviewed and current performance of D-ILA projectors characterized.
