Publication number: 20130320838Abstract: Certain example embodiments relate to organic light emitting diode (OLED) inclusive devices, and/or methods of making the same. A substrate supports a transparent conductive coating (TCC) based layer, and first and second organic layers disposed thereon. A reflective conductive layer is supported by the organic layers. An out-coupling layer stack (OCLS) interposed between the organic layers and a viewer of the device includes a hybrid organic-inorganic polymer matrix having scatterers dispersed throughout in a manner such that each scatterer is located in the far field of its nearest neighbor. The scatterers are dispersed to have a high Zeta potential, and promote Mie-like scattering of light passing through the OCLS. Mie-like scattering caused by the OCLS may help to frustrate the wave-guiding modes in the glass, e.g., by breaking down the in-phase coherence.Type: ApplicationFiled: June 5, 2012Publication date: December 5, 2013Applicant: Guardian Industries Corp.Inventor: Vijayen S.
