“…Using the same number of holographic dichroic mirrors and LCD panels as the primary colors enables higher resolution display with expanded color gamut, 13 although this leads to the larger display device and complicated optical arrangement. The optical system of transmission type DOE, proposed in this paper, sacrifices image resolution to increase the number of the primary color, but is simple and has compact architecture.…”

To reproduce the natural color of an object through color imaging systems, the range of the reproducible color, i.e., the color gamut, of the color display devices must be expanded, because the color gamut of current display devices such as cathode ray tubes (CRTs) and liquid crystal displays (LCDs) is insufficient. We present a new method to enlarge the color gamut for the LCD device using more than three primaries, i.e., multiprimaries, generated by a diffraction grating and a liquid crystal panel. The optical system for the multiprimary color display is introduced, and its capability of increasing the gamut is discussed. The experimental result displayed by seven primary colors is also demonstrated.
