Display system having coherent and incoherent light sources
Abstract:
Embodiments are disclosed that allow light display systems, such as projectors, to be manufactured having lower power consumption, reduced speckling, and/or that are less expensive than conventional light projectors. In some embodiments, may include an incoherent light source and a coherent light source operating in concert with one another to produce a combined light beam that has similar wavelength contributions from the incoherent and coherent light sources.
