Abstract
A display includes a lightguide arrangement in which at least part of the image light is not coupled-out from the lightguide during a first pass of a coupling-out arrangement, and is recirculated so as to pass repeatedly the coupling-out arrangement. In one set of embodiments, recirculation of light is performed via a separate lightguide. In another set of embodiments, light is recirculated within a single lightguide, employing polarization management to avoid unwanted interactions between the light and the coupling-out arrangement.
