A system and method are described for achieving a high efficiency, full color display using color sensitive lenses such as holographic lenses. A lens assembly is composed of discrete lens elements (1, 2, 3) which are sensitive to different wavelengths bands of light. Each lens element (1, 2, 3) focuses...http://www.google.de/patents/US4807978?utm_source=gb-gplus-sharePatent US4807978 - Color display device and method using holographic lenses
