Patent attributes
A near eye display apparatus includes: a lens having a viewing area, the lens comprising a waveguide having a waveguide input and a waveguide output optically coupled to the viewing area; an optical projector having a projector output, the optical projector comprising an illumination source optically coupled to the optical prism element and configured to provide illumination light into the optical prism element at a particular direction, a spatial light modulator optically coupled to the optical prism element and configured to receive the illumination light from the optical prism element and to reflect patterned light, the optical prism element configured to provide the patterned light to the projector output at the particular direction; and an optical folding element optically coupled between the projector output and the waveguide input, the optical folding element configured to fold an optical path of the patterned light in at least two different directions.
