Paper Abstract

In order to reproduce the natural color of object on color display devices, such as CRT and LCD (liquid crystal display), the saturation of the reproduced color is limited by the gamut of the display device. This paper presents a method to increase the color gamut by using more than three primary colors generated by a holographic optical element (HOE). The light diffracted by HOE is used to generate multiprimary colors, and the color image with extended color gamut is displayed by LCD device. Both transmission- and reflection-type systems suitable for projection displays are proposed, and the capability of increasing the gamut is discussed. The experimental result using transmission-type HOE is also demonstrated.
