Abstract: Embodiments of the disclosed subject matter provide a device that may include an organic light emitting device (OLED) having a substrate, a first electrode disposed over the substrate, a second electrode disposed over the first electrode, and an organic emissive layer having a first surface positioned over a second surface is disposed between the first electrode and the second electrode. A nanoparticle layer may be disposed over the organic emissive layer and has a first surface that is positioned over a second surface. The nanoparticle layer may include a first plurality of nanoparticles comprising a dielectric material, and a surrounding medium. A distance from the second surface of the nanoparticle layer to the first surface of the organic emissive layer may be not more than 50 nm, and there may be a difference of at least 1.0 between a refractive index of the dielectric material and the surrounding medium.

Abstract: High-efficiency plasmonic OLED displays are provided that use the design of the plasmonic device to overcome some of the shortcomings of conventional display panels. Control of the Stokes parameters of the emitted light and/or modification of the ambient light incident on the device relative to the emitted light is used to maximize the amount of visible light emitted by the display.
