  • OLED light extraction films having nanoparticles and periodic structures
    Patent number: 8692446
    Abstract: 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.
    Type: Grant
    Filed: March 17, 2011
    Date of Patent: April 8, 2014
    Assignee: 3M Innovative Properties Company
    Inventors: Jun-Ying Zhang, Encai Hao, Vivian W. Jones, Terry L. Smith, Sergey A. Lamansky, Ha T. Le, Dawn Qiu, William B. Kolb, James M. Battiato, David B. Stegall
