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 11):
The near-eye display apparatus of  claim 10 , wherein the waveguide optical element further comprises coupling incidence portions integrated with or combined with each waveguide plate into a whole, the coupling incidence portions are used for refracting light beams into each waveguide plate so as to make light entering said each waveguide plate satisfy an incidence condition of total internal reflection, at least one of the coupling incidence portions comprises a wedge deflection element.
