Passivation of electroluminescent organic devices

摘要

A method of passivating electroluminescent organic devices positioned on a supporting substrate including the steps of overcoating or capping the individual pixels, which form an array of electroluminescent organic devices, with a layer of stable metal, overcoating the layer of stable metal with a buffer system including a buffer layer of organic material and a thermal coefficient matching layer on the buffer layer, depositing a low permeability inorganic layer over the thermal coefficient matching layer, and sealing the electroluminescent organic device with an epoxy encapsulant or polymer laminated aluminum foil.
