ABSTRACT:
A scanning-light-band display apparatus includes a light-valve panel and an optical system. The optical system includes a multicolor light source and a faceted, rotatable light-transmissive polygonal prism. The light source projects illumination rays for forming images of red, green and blue light bands through the prism along different respective paths. A combination of optical components is arranged for intercepting the illumination rays and forming the images on the panel.
