  • Patent number: 11726235
    Abstract: Embodiments are disclosed for an optical waveguide display configured for use with a near-eye display (NED) device. In an embodiment the waveguide display includes a light-transmissive substrate and an optical coupling element configured to input light rays to the substrate or output light rays from the substrate, the optical coupling element configured to deflect a plurality of wavelengths of an incident light ray collinearly for propagation within the light-transmissive substrate through total internal reflection (TIR). The optical coupling element can include a pattern of nano-structures that collectively form a metasurface on the substrate.

  • Patent number: 10914956
    Abstract: A headset includes a first waveguide display and a second waveguide display. The first waveguide display is configured to emit a first portion of image light, the first waveguide display having a first field of view (FOV). The second display assembly is configured to emit a second portion of the image light, and the second display assembly has a second FOV. The first waveguide display and the second display assembly are tiled such that the emitted first portion of image light and the emitted second portion of image light create a tiled FOV from a perspective of an eyebox. And a seam between the first FOV and the second FOV is located in a peripheral region of the tiled FOV.
