Abstract

Methods and systems for a combination of up converters and semiconductor light sources in low voltage display or indicator system that can be battery powered. The display or indicator system includes one or more spatial light modulators and one or more up converters in combination with one or more semiconductor light sources. The spatial light modulator can be a liquid crystal display or a micro electro mechanical system or other spatial light modulator and can use direct modulation of the semiconductor light sources to modulate the visible emission from the up converters. The spatial light modulator can be placed between the up converting light source and the viewer or behind the up converting light source depending on the type of spatial light modulator, or modulation may be applied directly to one or more semiconductor light sources or arrays of semiconductor light sources that excite the up converters.
