Abstract
In a color projection display system employing display devices operating in the reflective mode, the optical path lengths are considerably reduced by employing prism illuminators immediately adjacent the display devices to illuminate the reflective display surface and to spatially separate the incident and reflected illumination. Such color projection systems are easier to arrange and offer sufficient brightness to be useful in both home and commercial applications, such as movie theaters.
