AUGMENTED/VIRTUAL REALITY NEAR EYE DISPLAY WITH EDGE IMAGING SPECTACLE LENS

摘要

A near eye display system having an image display panel, a prism assembly comprising a first and second element and a structure such as a eye wear glasses frame. The front and rear surfaces of the first and second elements are aligned and bonded to form the prism assembly. A partially-reflective coating is applied to the interface of the first and second elements to define a beam-splitter interface. The image display panel is disposed near an upper optical region such as a refracting surface of the first element. The lower edge of the second element opposite the beam-splitter interface is a coated reflective surface mirror. The display panel, the optical region and the optically reflective surface are configured to provide compactness and to avoid the break of symmetry. The system accommodates large inter pupil distance (IPD) variation and left/right eye scanning motion.
