More Information
Summary: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.
