Abstract:
A wearable augmented reality (AR) or virtual reality (VR) display apparatus includes an optical waveguide; an optical free-form surface; and a microdisplay; wherein optical free-form surface is optically coupled to the waveguide through an inclined optical path. A near-eye display apparatus includes two or more layers of waveguide plates arranged to overlap with each other, wherein within each layer of the waveguide plate includes multiple reflective surfaces different in reflectivity, so as to ensure that light transmitted through the waveguide plate has a substantially uniform distribution of intensity in a predetermined area when exiting outward from the waveguide plate. The waveguide optical element is ultrathin so as to be directly mounted into a spectacle frame. User experience and contrast level are also improved.

Claim (Index 10):
The near-eye display apparatus of  claim 5 , wherein the multiple partially reflective surfaces are configured to have different reflectivity to ensure that light exiting the waveguide plates has a substantially uniform intensity distribution in a predetermined area, the reflectivity of adjacent partially reflective surfaces satisfies the following formula: R N = R N - 1 1 - R N - 1 wherein N is a sequence number of the partially reflective surface, R 1  is reflectivity of the partially reflective surface closest to the coupling incidence portions.
