Polarized display with wide-angle illumination

摘要

A polarized display device having an expanded angle of illumination for optimizing a viewing angle in a desired plane comprises: a direct view a polarized display panel (200); and a transmissive polarization rotating element (230) proximate to an exterior surface of the polarized display panel, wherein the transmissive polarization rotating element rotates light polarization between a first linear polarization orientation (232) and a second linear polarization orientation (236).
