This report encompasses efforts directed toward the development of a multicolor display suitable for aircraft command and control applications. The approach taken was to superimpose the images from two 175 x 175 element matrix liquid crystal displays using a dichroic beam splitter such that one display formed a red image while the other display formed a green image. The two displays were illuminated by a Xenon arc lamp and the combined image was projected onto a screen. The resulting display presented red, yellow, and green symbology with high brightness 3300 fL for yellow, high contrast 141 for yellow, and good color purity, greater than 90 for all colors.
