MULTIBEAM DIFFRACTION GRATING-BASED BACKLIGHTING |
摘要 |
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 to guide light from a light source. The multibeam diffraction grating is to couple out a portion of the guided light using diffractive coupling and to direct the coupled out portion away from the light guide as a plurality of light beams with different principal angular directions. |

1. A multibeam diffraction grating-based backlight comprising:
a light guide to guide light from a light source; a multibeam diffraction grating at a surface of the light guide, the multibeam diffraction grating to couple out a portion of the guided light using diffractive coupling, the coupled out portion of the guided light being directed away from the light guide surface as a plurality of light beams, a light beam of the plurality having a different principal angular direction from other light beams of the plurality. |
