45.3: Micro‐structured Polymeric Linearly Polarized Light Emitting Lightguide for LCD Illumination

Abstract

Abstract A new linearly polarized light emitting lightguide system is presented, consisting of a micro‐structured anisotropic polymer film which is coated with an isotropic layer and adhered to a transparent polymeric substrate. With conventional edge‐lighting of the lightguide very high polarized contrasts are realized, exceeding 100. A gain in efficiency can be achieved by recycling of the trapped light with the orthogonal polarization.
