POLARIZED LIGHT-EMITTING WAVEGUIDE PLATE

A polarized light emitting waveguide plate comprises an entrance side for coupling light into the wave guide plate, a major exit surface for coupling light out of the waveguide plate, and a polarizer for selectively directing a component of a first polarization state of light coupled in via the entr...

Beschreibung
Zusammenfassung:	A polarized light emitting waveguide plate comprises an entrance side for coupling light into the wave guide plate, a major exit surface for coupling light out of the waveguide plate, and a polarizer for selectively directing a component of a first polarization state of light coupled in via the entrance side towards the exit surface, the polarizer comprising an anisotropically light scattering layer which selectively scatters the component of the first polarization state towards the exit surface. Preferably, the waveguide plate is made of conventionally processed polymeric materials in the form of a laminate of waveguide substrate, anisotropically light scattering layer and, optionally, an optically transparent cover layer.
