Abstract: Embodiments are described of an apparatus including an eyepiece having a front surface, a back surface spaced apart from the front surface, and an edge forming a perimeter of the eyepiece. The eyepiece includes an angled surface to direct light eye-measurement light reflected from an eye into the eyepiece and to direct display light out of the eyepiece to the eye. A first waveguide is formed in the eyepiece and extending from the angled surface to the edge, the first waveguide being optically coupled to a first portion of the angled surface having a first surface treatment. And a second waveguide is formed in the eyepiece and extending from the angled surface to the edge, the second waveguide being optically coupled to a second portion of the angled surface having a second surface treatment.

Abstract: A display apparatus includes a transparent substrate having first and second sides, an array of LED micro-display panels, and an array of collimating reflectors. The LED micro-display panels are disposed within the transparent substrate between the first and second sides and oriented to emit sub-image portions of a display image towards the first side. The collimating reflectors are disposed within the transparent substrate between the first side and the array of LED micro-display panels. The collimating reflectors are aligned with the LED micro-display panels to reflect the sub-image portions back out the second side of the transparent substrate. The LED micro-display panels are offset from the collimating reflectors to expand the sub-image portions prior to reflection by the collimating reflectors.

Abstract: An eyepiece for a head wearable display includes a light guide component for guiding display light received at a peripheral location offset from a viewing region and emitting the display light along an eye-ward direction in the viewing region. The light guide component includes an input surface to receive the display light into the light guide component, an eye-ward facing side, a world facing side, a total internal reflection (“TIR”) portion disposed proximal to the input surface to guide the display light received through the input surface using TIR, and a partially reflective portion including a partially reflective element disposed over the eye-ward facing side and a switchable reflector disposed over the world facing side. The partially reflective portion is disposed to receive the display light from the TIR portion and to guide the display light via reflections off of the partially reflective element and the switchable reflector.

Abstract: A lightguide assembly including structures to provide for outcoupling of light from an internal reflection structure. In an embodiment, a lightguide assembly includes light transmissive bodies forming respective corrugations which are coupled to one another. Optical coatings are variously disposed between the respective corrugations, wherein the optical coatings provide for redirection of light from the lightguide assembly. In another embodiment, optical coatings are each applied to a respective one of alternate facets of a corrugation. Polymer film portions provide mechanical support for the optical coatings during application to the corrugation.

Abstract: An apparatus for use with a head wearable display includes a curved eyepiece for guiding display light received at an input surface peripherally located from a viewing region and emitting the display light along an eye-ward direction in the viewing region. The curved eyepiece includes an optical combiner, an eye-ward facing surface that is concave, a world facing surface that is convex, and a curved lightguide disposed between the eye-ward facing and world facing surfaces to guide the display light via total internal reflections from the input surface to the viewing region. The optical combiner is disposed within the curved eyepiece at the viewing region to redirect the display light towards the eye-ward direction. The optical combiner includes a pattern of reflective elements separated by interstitial regions. The interstitial regions pass ambient light incident through the world facing surface such that the viewing region is partially see-through.

Abstract: An eyepiece for a head wearable display includes a curved lightguide component, a curved see-through component, an output coupler, and a prescription layer. The curved lightguide component guides display light received at an input region and releases the display light along an eye-ward direction in a viewing region. The output coupler is disposed at the viewing region to redirect the display light towards the eye-ward direction for output from the curved lightguide component. The output coupler is at least partially transmissive to ambient light incident through a world-facing side such that the viewing region is see-through. The curved see-through component is mated to the world-facing side of the curved lightguide component. The prescription layer has a first side mated to an eye-facing side of the curved lightguide component and a second side having a curvature that introduces prescriptive lensing to both the ambient light and the display light.
