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 14):
The polychromatic grating-coupled backlight of  claim 11 , wherein the color-specific, non-zero propagation angles of the plurality of light beams of the guided light are configured to mitigate color dispersion of the respective different colors of light by the multibeam diffraction grating.
