Abstract:
Multibeam diffraction grating-based backlighting includes a light guide and a multibeam diffraction grating at a surface of the light guide. The light guide is configured to guide light from a light source. The multibeam diffraction grating is configured to couple out a portion of the guided light using diffractive coupling and to direct the diffractively coupled out portion away from the light guide as a plurality of light beams with different principal angular directions having directions corresponding to view directions of a multiview display.

Claim (Index 1):
A multibeam diffraction grating-based backlight comprising:\n a light guide configured to guide light from a light source as guided light; and a plurality of multibeam diffraction gratings arranged across the light guide, each multibeam diffraction grating of the multibeam diffraction grating plurality being configured to couple out a portion of the guided light using diffractive coupling, the diffractively coupled-out portion of the guided light being directed away from a surface of the light guide as a plurality of light beams, a light beam of the light beam plurality having a different principal angular direction from other light beams of the light beam plurality, wherein different principal angular directions of the plurality of light beams correspond to directions of different views of a multiview display.
