Abstract:
Polychromatic backlighting employs a grating coupler to diffractively split and redirect collimated light coupled into a light guide. A polychromatic grating-coupled backlight includes a light guide configured to guide light and a light source to provide collimated polychromatic light. The polychromatic grating-coupled backlight further includes the grating coupler diffractively split and redirect to provide a plurality of light beams. Each light beam of the plurality represents a respective different color of the polychromatic light and is configured to propagate within the light guide as guided light at a color-specific, non-zero propagation angle corresponding to the respective different color of polychromatic light. An electronic display includes the polychromatic grating-coupled backlight and further includes a diffraction grating to diffractively couple out a portion of the guided light and a light valve array to modulate the coupled-out light as an electronic display pixel.

Claim (Index 10):
The polychromatic grating-coupled backlight of  claim 1 , further comprising a diffraction grating at a surface of the plate light guide, the diffraction grating being configured to diffractively couple out a portion of the guided light as a coupled-out light beam having a predetermined principal angular direction emitted from the plate light guide surface, the coupled-out portion comprising the different colors of polychromatic light.
