REAR PROJECTION SCREEN

摘要

A rear projection screen, made of a substantially one piece unit, forms at least on its viewing side with lenticular projections having crests and troughs being connected by flanks. Each frank totally reflects light impinging from the screen's projection side, and the reflected light emanates from the screen through the crest, characterized in that the lenticular projections (1) are longitudinally and vertically extending lens units arranged parallel to one another. The crest comprises a concave surface (11) and each trough is formed with a lens surface (12A).
