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 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: Techniques and mechanisms for fabricating an eyepiece from a lens blank including blank bodies that are bonded to each other. In an embodiment, the blank bodies are formed by injection molding and adhered to one another. Fabrication of the eyepiece includes variously machining the blank bodies to shape respective lens bodies of the eyepiece. One or more blocking structures are coupled to reinforce the lens blank during at least part of such machining. In another embodiment, any blocking structures that are to resist forces of a particular machining process are coupled only indirectly to one of the blank bodies.

Abstract: Implementations are described of an eyepiece for a head wearable display. The eyepiece includes a curved lightguide for guiding display light via total internal reflection between a peripherally-located input surface and a viewing region and an output coupler disposed across the viewing region to redirect the display light towards an eyeward direction for output from the curved light guide. The output coupler has an optical axis and has a set of reflective surfaces that includes at least two individual reflective surfaces to reflect incident display light toward the eyeward direction in at least two different directions relative to the optical axis of the output coupler. Other embodiments are disclosed and claimed.

Abstract: An apparatus for use with a head wearable display includes a curved eyepiece for guiding display light to a viewing region offset from a peripheral location and emitting the display light along an eye-ward direction in the viewing region. The curved eyepiece includes a curved lightguide to guide the display light, an eye-ward facing surface that is concave, a world facing surface that is convex and opposite the eye-ward facing surface, and an optical combiner disposed at the viewing region to redirect the display light towards the eye-ward direction for output from the curved lightguide. The optical combiner is partially transmissive to ambient light incident through the world facing surface such that the viewing region is see-through. In some embodiments, a prism is disposed proximate to the input surface to pre-compensate the display light for lateral chromatic aberrations resulting the curved lightguide.
