Abstract
A near-eye display includes a light-guide optical element (LOE) () having first and second major external surfaces (A,B) that are planar and mutually parallel. An image projector () introduces into the LOE illumination corresponding to an image so that the illumination propagates within said LOE by internal reflection at the major external surfaces. A coupling-out arrangement couples the illumination out of the LOE towards the eye of the observer. The coupling-out arrangement may be a set of mutually-parallel, partially-reflective surfaces (A) deployed at an oblique angle within the LOE. Various arrangements for suppressing reflections of ambient light sources include obstructing baffles oriented so as to avoid reduction of peripheral field of view, various non-reflective coatings and various deployments of polarization filters.
