Abstract:
A diffractive backlight system includes a light source and a plate light guide. A surface of the plate light guide is configured with a diffraction grating that couples light out of the plate light guide and concentrates the light into a localized region of space. The diffractive backlight system may be used with at least one light valve array to form a display that generates images for viewing in the localized region of space. The display may be incorporated in head-mounted displays in order to generate focused augmented or virtual reality images for wearers.

Claim (Index 13):
A head-mounted display comprising:\n a plate light guide having a diffraction grating configured to diffractively couple out a portion of light input to the plate light guide and concentrate light coupled out of the plate light guide into an eyebox; a first light valve array oriented substantially parallel to the plate light guide and positioned so that the light coupled out of the plate light guide passes through the first light valve array; and a display control connected to the first light valve array, the display control operating the first light valve array to form an image in the eyebox.
