OLED LIGHT EXTRACTION FILMS HAVING NANOPARTICLES AND PERIODIC STRUCTURES
摘要
<p>A light extraction film having nanoparticles with engineered periodic structures. The light extraction film includes a substantially transparent substrate, low index one-dimensional or two-dimensional periodic structures on the substrate, and a high index planarizing backfill layer applied over the periodic structures. Light scattering nanoparticles are either applied in a layer over the periodic structures or included in the backfill layer.</p>
