Polarized light emitting diode (LED) color illumination system and method for providing same

摘要

A polarized light illumination system includes a light emitting diode (LED) ( 601, 602, 603 ) for providing a source of light that is directed to a non-polarizing dichroic combiner ( 607 ) for combining light from the LEDs into a single light source. A power beam splitter (PBS) ( 608 ) is then used for splitting the single light source into polarized light components and an output waveguide ( 611 ) operates to provide a source of uniformly illuminated light. A condenser lens ( 612 ) then projects the uniformly illuminated light to a microdisplay panel ( 613 ) for use with a television receiver or other type of display monitor.
