OLED OLED DEVICE HAVING ENHANCEMENT LAYERS

摘要

The present invention provides an enhancement layer at or below a threshold distance from the organic light emitting layer to maximize the non-radiative transfer of excited state energy from the organic light emitting material of the OLED to the surface plasmon polaritons in the enhancement layer; A method of improving the operation of an OLED comprising scattering energy from the surface plasmon polariton through an outcoupling layer provided proximate to the enhancement layer, but opposite the organic light emitting layer, thereby emitting light from the enhancement layer into free space.
