Patent abstract
A polarized backlight employs a light source configured to provide polarized light and a light guide to guide the polarized light. A polarization-preserving scattering feature optically coupled to the light guide is configured to scatter a portion of the guided polarized light out of the light guide as emitted polarized light. A polarization of the emitted polarized light is determined by a polarization of the guided polarized light.
