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 oriented to receive the display light into the light guide component, an eye-ward facing surface having a reflection portion and a viewing portion, a folding surface oriented to reflect the display light received through the input surface to the reflection portion of the eye-ward facing surface, and a first interface surface oriented to receive the display light reflected from the reflection portion of the eye-ward facing surface. A partially reflective layer is disposed on the first interface surface in the viewing region to reflect the display light along the eye-ward direction through viewing portion of the eye-ward facing surface.
