Abstract
A digital projection display system includes one or more digital projection displays. Each digital projection display has an external light source producing as an output a light beam, an internal optics system, and a housing in which the internal optics system is received, but wherein the external light source is located external to the housing. A display screen forms one face of the housing. Preferably, an optical fiber extends from the output of the external light source to an input of the internal optics system. Multiple digital projection displays may be illuminated by a single external light source using multiple optical fibers.
