1. An imaging panel comprising:
- a light source including a light emitter and a waveguide having a grating, the waveguide configured to confine the light from the light emitter and to release the light through the grating;
a reflective image-forming array configured to form a display image using light from the light source and to reflect the display image back through the waveguide; and
a freeform-prism eyepiece configured to receive the display image and to present the display image for viewing, together with an external image transmitted through the eyepiece.

Abstract
An imaging panel includes a light source, a reflective image-forming array, and a freeform-prism eyepiece. The light source includes a light emitter and a waveguide having a grating. The waveguide is configured to confine the light from the light emitter and to release the light through the grating. The reflective image-forming array is configured to form a display image using light from the light source and to reflect the display image back through the waveguide. The freeform-prism eyepiece configured to receive the display image and to present the display image for viewing, together with an external image transmitted through the eyepiece.
