Abstract
Example display devices include a waveguide configured to propagate visible light under total internal reflection in a direction parallel to a major surface of the waveguide. The waveguide has formed thereon an outcoupling element configured to outcouple a portion of the visible light in a direction normal to the major surface of the waveguide. The example display devices additionally include a cholesteric liquid crystal (CLC) reflector disposed on a forward side of said waveguides, said CLC reflector configured to have an optical power or a depth of focus that is adjustable upon application of an electrical signal. The out-coupling element is disposed to extract light from the waveguide and direct at least a portion of said light propagating within said waveguide to the CLC reflector, said light being directed from said CLC reflector back through said waveguide and into said eye to present an image from the optical display into the eye of the wearer.
