Abstract

A display includes a projector configured to provide light of a virtual image, a waveguide into which the light of the virtual image is injected at an injection angle by the projector, and a combiner disposed along the waveguide and configured to redirect the light of the virtual image. The waveguide is configured to emit the light at a point established by the injection angle. The combiner is further configured to allow ambient light from beyond the waveguide to pass through the combiner. The waveguide constrains the light of the virtual image through total internal reflection along a curved path for the light between the projector and the combiner.
