Organic light emitting diodes (OLEDs) include a polymeric barrier coating that is a copolymer of ethylene and substituted vinyl constituents configured to protect the OLEDs from both oxygen and water. The substituted vinyl of the coating may be selected, in conjunction with the permeability properties provided by the ethylene, to include chemical structures, physical structures, and chemical functional groups that effectively and efficiently create a barrier towards both oxygen and water. Methods for producing and using the coatings are also disclosed.
