Abstract: A head mounted display includes a combiner configured to receive display light from a micro-display. The world-facing surface of the combiner has a curvature that corresponds to a user's vision correction prescription. The head mounted display also includes a corrective layer having a second curvature that corresponds to the user's vision correction prescription. The corrective layer is disposed on the eye-facing surface of the combiner such that the focal point of the display light is adjusted for the specific user as the display light exits the combiner towards the user's eye.

Abstract: A head mounted display (HMD) device and method of manufacturing the same. The HMD includes a frame housing a micro-display to project display light, a lightguide configured to receive the display light from the micro-display, and a corrective layer having a world-side surface coupled to the eye-side surface of the lightguide. The lightguide is further configured to have a world-side surface with a radius of curvature based on an ophthalmic corrective prescription and an eye-side surface having an outcoupler feature formed thereon such that the coupled lightguide and corrective layer form a lens configured to fit within the frame.

Abstract: A head mounted display includes an eyeglasses frame, a lens framed in the eyeglasses frame, and a light engine disposed in the eyeglasses frame. The lens includes an optical shell comprising a world-facing spherical surface and an opposing eye-facing surface and a curved lightguide disposed in the optical shell. The curved lightguide includes an incoupler surface, a first freeform surface facing the world-facing spherical surface, and a second freeform surface facing the eye-facing surface. The lens further includes a first low refractive index region disposed between the first freeform surface and a first conformal freeform surface of the optical shell and a second low refractive index region disposed between the second freeform surface and a second conformal freeform surface of the optical shell.

Abstract: An optical device includes a lightguide and a display at a top of a head mountable frame. The display is oriented toward an eye-side of the optical device. A reflector is positioned at an eye-side of the optical device and directs light into the lightguide. This orientation and arrangement of components reduces light leaking out of the optical device. The lightguide includes curved first and second surfaces. The device reflects light through the curved first surface to a user eye for augmented reality vision. A head mountable frame supports the display, the reflector, and the lightguide.

Abstract: A mobile computing device includes an emissive display panel, where the panel is used as a grating, and spectrometer optics positioned behind/below the emissive display panel. A mobile computing device includes an emissive display panel and a spectrometer positioned below the emissive display panel. The emissive display panel includes a first periodic pattern of pixels that include one or more LEDs and a second periodic pattern of circuit elements that control the pixels, where the first and second periodic patterns are configured to diffract light received from outside the device, which passes through the emissive display, and where the diffraction is wavelength-dependent. The spectrometer is configured to detect intensities of different wavelength ranges of the diffracted light.

Abstract: A lightguide includes an incoupler configured to receive light emitted from a microdisplay and to direct the received light into the lightguide, a first non-planar major surface and a second non-planar major surface configured to reflect the light directed into the lightguide by the incoupler, and an outcoupler comprising a non-planar, angle selective hologram configured to receive light reflected from at least one of the first major surface and the second major surface and to selectively direct the light out of the lightguide based on the angle of incidence at the hologram.
