OLED OLED LIGHT EXTRACTION FILMS HAVING NANOPARTICLES AND PERIODIC STRUCTURES

摘要

A light extraction film having nanoparticles and a processed periodic structure. The light extracting film comprises a substantially transparent substrate; A one-dimensional or two-dimensional periodic structure of low refractive index on a substrate; And a high refractive backfill layer applied over the periodic structure. The light scattering nanoparticles are applied as a layer on the periodic structure or contained in the backfill layer.
