Abstract:
A light concentrating backlight includes a light guide to guide light and a diffraction grating configured to diffractively couple out a portion of the guided light as diffractively coupled-out light and to concentrate the diffractively coupled-out light into an eyebox. A near-eye display system includes the light guide and the diffraction grating, and further includes a light valve array configured to modulate the diffractively coupled-out light to form an image in the eyebox. The formed image is configured to be viewable within the eyebox by a user.

Claim (Index 20):
A method of near-eye display operation, the method comprising:\n guiding light in a light guide as guided light; concentrating light in an eyebox located adjacent to the light guide using a diffraction grating to diffractively couple out and direct a portion of the guided light into the eyebox; and modulating the concentrated light using a light valve array between the light guide and the eyebox to form an image within the eyebox.
