Abstract: 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.

Abstract: A direct view display provides a light modulating panel and a backlight including first and second sets of spectral emitters. The first set of spectral emitters generate a first light bundle and the second set of spectral emitters generate a second light bundle. Several modes of operation may be provided including (1) an advanced 2D mode, (2) an enhanced color gamut mode employing simultaneous illumination of the first and second set of spectral emitters, (3) a privacy screen mode, (4) a channel multiplexed mode, and (5) a stereoscopic image mode. The latter three modes utilize the first and second set of spectral emitters to alternately illuminate a portion of the light modulating panel. Images and representations generated by the direct view display operating in the latter three modes are viewed using appropriate eyewear having filters with passband characteristics to transmit the respective light bundle.
