Waveguide combiner with in-plane relay and waveguide display system including the same

Abstract

A system includes a waveguide configured to guide an in-coupled image light to propagate inside the waveguide via total internal reflection. The system also includes an in-coupling element configured to couple an input image light into the waveguide as the in-coupled image light. The system also includes a plurality of partial reflectors at least partially embedded inside the waveguide. The system further includes an in-plane relay at least partially embedded inside the waveguide and disposed between the in-coupling element and the partial reflectors. The in-plane relay includes a plurality of cylindrical reflectors. The in-plane relay is configured to convert the in-coupled image light received from the in-coupling element into a relayed image light.
