graphs above show the chromaticity diagram and the loci of primaries used beside the NTSC standard tv primaries

image right shows the main optic and hardware componenents for the system
(1), (2) and (3) red, green and blue LED units
(4) beam splitter (5a) DMD unit illuminated by composed led beams (5b) exit for image
(6) DMD TI controller (7) RGB sensor unit
