Abstract
The present invention relates to a light valve projector in which a small high resolution active matrix transmission display is used with a light source, coupling optics and a projection lens to provide a compact presentation system. A preferred embodiment of the system comprises a three light valve system with an arc lamp within a compact housing in which dichroic mirrors separate light from the source into three primary colors and directs the separated light through three active matrix displays manufactured by a thin film transfer process and having a small active area.
