Abstract

Method and system for an up conversion lighting system for use with displays. The system includes an up converter-semiconductor light source for emitting an up conversion emission and a spectrally selective optical element in the path of the emission for selectively passing selected wavelengths. The optical element has a coating selected to pass selected wavelengths. The up converter-semiconductor light source includes an up converter for emitting the up conversion emission, a semiconductor light source coupled with the up converter to excite an up conversion material within the up converter to emit an up conversion emission and a spatial light modulator for modulating the up conversion emission. For a full color display, the up converter includes a red, green and blue up converter and a separate a light source coupled with the red, green and blue up converters. The spectrally selectively optical element can be a spectrally selectively beam splitter having a film coating that is sele
