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.
Claims21
-94. (canceled)
A device comprising:
- a substrate;
- a first electrode disposed over the substrate;
- an organic emissive material disposed over the first electrode;
- an enhancement layer comprising a plasmonic material that exhibits surface plasmon resonance disposed over the organic emissive material;
- and
- an outcoupling layer comprising metal nanostructures disposed over the enhancement layer that causes light emitted by the device to have circular polarization with a Stokes parameter S3 having an absolute value of 0.1 or greater.
