Patent ID: 8692855

Claim:
A 3D display, comprising: a modulating panel; a plurality of light sources; and a plurality of spectral filters each paired with at least one of the light sources and positioned to separate spectra of light emitted from its paired light source into a first spectra having wavelengths consistent with a first-eye channel and a second spectra having wavelengths consistent with a second-eye channel of the 3D display; wherein the plurality of light source spectral filter pairs are arranged so as to illuminate the modulating panel in a first-eye channel & second-eye channel illumination sequence that corresponds to a first-eye channel & second-eye channel image sequence displayed on the modulation panel such that the spectra of first-eye channel is modulated by the first eye channel image data and the spectra of the second-eye channel is modulated by the second-eye channel image data; and wherein the plurality of light sources are arranged in an edge lit configuration such that the light sources are positioned off an edge of the modulating panel; and wherein the first eye channel and second eye channel illumination sequence comprises a sequence illuminating at least four areas on the modulating panel, the sequence comprising, illuminating a first area with a first spectra and a third area separate from the first area with a second spectra during a first time interval, illuminating the first area with the second spectra and the third area with the first spectra during a second time interval, illuminating a second area with the first spectra and a fourth area separate from the second area during a third time interval, and illuminating the second area with the second spectra and the fourth area with the first spectra during a fourth time interval.
