Abstract
An eyepiece for a head wearable display includes a lightguide component for guiding display light and emitting the display light along at a viewing region. The light guide component includes an input surface oriented to receive the display light into the lightguide component at the peripheral location, a first folding surface disposed to reflect the display light received through the input surface, a second folding surface disposed to reflect the display light received from the first folding surface, an eye-ward facing surface disposed opposite to the second folding surface to reflect the display light received from the second folding surface, and a curved reflective surface having reflective optical power disposed at the viewing region to receive the display light reflected from the eye-ward facing surface and to reflect the display light for emission out through the eye-ward facing surface.
