Abstract
A polarizing waveguide plate includes a pair of spaced transparent plates that define a gap therebetween. Disposed within the gap is a composite material formed of a mixture of polymer mater and liquid crystal material. Positioned proximate to one edge of the gap is an edge light, while a reflector/converter is positioned proximate to another edge of the gap. During operation, unpolarized light is emitted from the edge light and is received within the gap. As such, a portion of the light polarized in a first direction is permitted to exit the waveguide, while the remaining portion of the light that is polarized in a second direction, orthogonal to the first direction, is converted by the converter/reflector so that its polarization is also in the first direction. As such, substantially all of the unpolarized light from the edge light is emitted by the polarizing waveguide plate as polarized light.
