Abstract
A polarized light illumination system includes a light emitting diode (LED) () for providing a source of light that is directed to a non-polarizing dichroic combiner () for combining light from the LEDs into a single light source. A power beam splitter (PBS) () is then used for splitting the single light source into polarized light components and an output waveguide () operates to provide a source of uniformly illuminated light. A condenser lens () then projects the uniformly illuminated light to a microdisplay panel () for use with a television receiver or other type of display monitor.
