Abstract
Efficient rear projection systems are made manufacturable by utilizing diamond turning technology and compression molding techniques. Present manufacturing methods allow a variety of refractive surfaces and diffusers to be molded in thermoplastic. Screens can be designed to have specific light distributions that maximize light output into a given viewer space. Use of rear projection for demanding applications such as large aperture television systems is increasing. It is likely that rear projection will continue to replace front projection systems as the cost, performance and size of the rear projection screens are improved.
