Abstract
A light emitting device, includes a light emitting diode unit on a substrate; a gas-generating species; an inert gas; a barrier; and a sealant; wherein: the sealant, barrier, and substrate define a protective chamber; and the light emitting diode unit, the gas generating species, and the inert gas are disposed within the chamber.
Claims28
A light emitting device, comprising:
- a light emitting diode unit deposited on to a substrate;
- a gas-generating species;
- a barrier;
- and
- a sealant;
- wherein:
- the sealant, barrier, and substrate define a protective chamber;
- the light emitting diode unit, the gas generating species, and the inert gas are disposed within the chamber;
- and
- the gas generating species comprises 40K, a carbodiimide, an azo-compound, a cyanamide, a trizaole, an isocyanate or a combination of any two or more thereof.

A process for the manufacture of an light emitting device, the process comprising:
- depositing an light emitting diode unit on a substrate;
- depositing a gas generating species on the substrate;
- overlaying the light emitting diode unit with a barrier material;
- and
- sealing the barrier material to the substrate with a sealant;
- wherein:
- the barrier, sealant, and substrate define a protective chamber encapsulating the organic light emitting diode unit, and the gas generating species;
- and
- the gas generating species comprises 40K, a carbodiimide, an azo-compound, a cyanamide, a trizaole, an isocyanate or a combination of any two or more thereo.
