Abstract: Embodiments herein are generally directed to a waveguide display assembly and a near-eye display system incorporating the waveguide display assembly. In an embodiment, the waveguide display includes a light engine, a waveguide combiner, an input coupling grating, and one or more coupling gratings exposed to an ambient environment of the waveguide display assembly. The waveguide combiner extends across a user's eye at a wrap angle θwrap(xy) relative to a waveguide plane, and the light engine is configured to project light toward the input coupling grating at a compensation angle θCl so as to increase the grating vector of the exposed gratings and reduce the angles and wavelengths at which light can be diffracted and coupled by the exposed grating into the waveguide combiner to the user's eye.

Abstract: A rainbow-free waveguide display, a near-eye display incorporating the rainbow-free waveguide, and methods of manufacturing the rainbow-free waveguide are provided. The display includes a waveguide display configured to direct image light to an eyebox plane having a length (LEyebox) and to a user's eye. The waveguide display includes a waveguide combiner and an out-coupler grating, wherein the out-coupler grating has a grating period ΛOC such that all angles of incidence θin of light from an external light source, result in diffracted angles θout, that miss the user's eye.

Abstract: Embodiments of the present disclosure generally relate to methods for forming a waveguide. Methods may include measuring a waveguide substrate, the waveguide having a substrate thickness distribution; and depositing an index-matched layer onto a surface of the waveguide, the index-matched layer having a first surface disposed on the waveguide substrate and a second surface opposing the first surface, wherein the index-matched layer is disposed only over a portion of the waveguide substrate, and a device slope of a second surface of the index-matched layer is substantially the same as the waveguide slope of the first surface of the waveguide.
