Within a 500h test, ALD encapsulated poly-LEDs show approximately half the black spot density of plasma deposited a-SiNx:H (300 nm thick) encapsulated devices. The black spot density is further reduced ifthe a-SiNx:H layer is coupled with an ALD layer and such decrease is accompanied by a massive reduction of the black spot area growth in time. A selection of electroluminescence measurements of encapsulated poly-LEDs point out a very promising application of ALD Al2O3 layers in the field of LED encapsulation and will be interpreted in terms of possible mechanisms related to film growth in multi-layer structures.
