Abstract
A high efficiency polarizing converter receives generally collimated light of arbitrary polarization and converts it to light of a selected polarization with minimal loss or absorption of light. In one embodiment, the polarizing converter has a generally planar configuration that is suitable for flat panel displays, LCD projectors, and other display applications.
