Abstract:
Techniques disclosed herein relate to folded optical systems for near-eye display. In one embodiment, an optical device includes a first polarizer, a second polarizer, and a partial reflector positioned between the first polarizer and the second polarizer. The first polarizer is configured to polarize incident light into light of a first circular polarization state. The second polarizer is configured to transmit light of a second circular polarization state and reflect light of the first circular polarization state without changing its polarization state. The partial reflector is configured to transmit light from the first polarizer, and reflect light from the second polarizer. The light reflected by the partial reflector and the light from the second polarizer have different polarization states.

Claim (Index 21):
A near-eye display device comprising:\n a display including an output surface, wherein:\n the display is configured to emit display light through the output surface; and \n the output surface is configured to at least partially reflect light incident on the output surface from an exterior of the display, wherein the partially reflected light and the light incident on the output surface from the exterior of the display have different polarization states; and \n a reflective circular polarizer formed on the output surface of the display and including liquid crystal molecules arranged in a helical structure, the reflective circular polarizer configured to:\n reflect light of a first circular polarization state in the display light back to the output surface of the display, wherein the reflected light from the reflective circular polarizer to the output surface of the display is in the first circular polarization state; and \n transmit light of a second circular polarization state in the display light to a user's eye, wherein the light transmitted to the user's eye maintains the second circular polarization state.
