Abstract:
A light-weight and ultrathin waveguide optical element having a large field of view includes two or more layers of waveguide plates provided to be overlapped with each other. Within each layer of the waveguide plate are included multiple reflective surfaces with different reflectivity, such that light transmitted through the waveguide plate has a substantially uniform distribution of intensity in a predetermined area when exiting from the waveguide plate. The waveguide optical element is ultrathin such that it can be directly mounted into a spectacle frame. Use of the waveguide optical element with a projection optical assembly can improve user experience as well as display effect with good contrast.

Claim (Index 15):
A near-eye display apparatus, comprising:\n a waveguide optical element, comprising:\n at least two waveguide plates arranged to overlap in parallel, with a predetermined gap therebetween, each waveguide plate comprising two main surfaces parallel to each other, and transmitting light coupled into the waveguide plates in a predetermined direction through total internal reflection; and \n one or more partially reflective surfaces respectively located inside each of the waveguide plates, and arranged within a space between the main surfaces as a beam-split surface at a characteristic angle with the main surfaces; wherein the one or more partially reflective surfaces inside the waveguide plates are distributed in different areas along the direction of the main surfaces; \n a housing; a projection optical assembly; and a micro-display, wherein the projection optical assembly is disposed inside the housing for projecting image light emitted from the micro-display to the waveguide optical element, so as to transmit in the waveguide optical element.
