Abstract: An electronic device may include a display with a display panel that emits light into an optical system. The system provides the light and world light to an eye box. The system may be implemented using a folded birdbath architecture. The system may include a partial reflector and a reflective polarizer in freeform curved rotationally asymmetric surfaces. The system may include two or three optical wedges. An air gap may separate two of the wedges. A quarter waveplate may be layered over the reflective polarizer and/or the partial reflector. A privacy filter may overlap the partial reflector. The wedges may perform total internal reflections on the light. The system may provide a horizontal field of view of the light to the eye box at a different point than a vertical field of view. A switchable shutter may overlap the system and may be synchronized to an external device display.

Abstract: An electronic device may include a display panel configured to produce light and a lens assembly that receives the light from the display panel. The lens assembly may be a catadioptric lens assembly with a partially reflective layer, lens element, quarter wave plate, and reflective polarizer. Some of the light emitted by the display panel may be reflected by the catadioptric lens assembly away from the catadioptric lens assembly. A supplemental mirror may be used to reflect this light back towards the catadioptric lens assembly. The supplemental mirror may increase the field-of-view of images viewable through the catadioptric lens assembly. The supplemental mirror may have a dithered upper surface or a phase-shift mask.
