OLED light extraction using nanostructured coatings

Abstract:

An apparatus for light diffraction and an organic light emitting diode (OLED) incorporating the light diffraction apparatus is disclosed. An apparatus for light diffraction may comprise an optional planarization layer, a transparent substrate, a waveguide layer. The planarization layer may have a refractive index of n.sub.s. The transparent substrate may have a refractive index of n.sub.g. The waveguide layer may have a refractive index n.sub.w distributed over of the transparent substrate. The waveguide layer may comprise a binding matrix, at least one nanoparticle. The waveguide layer may be interposed between the transparent substrate and the optional planarization layer.
