Color LCD projector with micro display light engine

摘要

A light engine for an LCD projector is disclosed. More particularly, a liquid crystal display projector including a light source emitting a light beam, a light engine, and a projection lens is disclosed. The light engine includes a polarizing beam splitter for receiving the light beam from the light source. The polarizing beam splitter orthogonally reflects a light beam containing multiple colors and passes a first light beam containing a single color. The light engine also includes a dichroic prism that receives the light beam containing multiple colors, reflects a second light beam containing a single color, and passes a third light beam containing a single color. Further, the light engine includes reflective liquid crystal displays associated with each of the first, second, and third light beams containing a single color for receiving, modulating, and reflecting modulated first, second, and third light beams containing a single color for recombination and projection through the projection lens.
