摘要： Described are methods, systems and apparatuses that provide light sources to illuminate an LCD panel for a visual display. A light source includes a light emitting diode (LED) and a spectral filter. The spectral filter is operable to transmit a first set of spectral bands and block a second set of spectral bands from the LED. The spectral filter may be based on retarder stack technology or dichroic filter technology. Polarization and light recirculation techniques are disclosed and implementations into display systems described. These approaches are deemed useful for LED illuminated direct view color encoded stereoscopic systems based on LCD technology.

摘要： A compact and efficient illumination system is provided that is particularly suitable for illuminating a micro display and places the light source within the view of the display. In one embodiment, the illumination system comprises a light source, a package for the light source having a reflective surface on at least one side of the light source, and a diffuser opposite the reflective surface in direct view of the light source. The invention further comprises a film stack to receive light through the diffuser, the film stack transmitting light within a maximum exit angle and reflecting substantially all other light to the diffuser.
