Patent ID: 6977391

Claim:
An encapsulated organic optoelectronic device, comprising: a substrate; an organic optoelectronic device on said substrate, said organic optoelectronic device includes a cathode; a diffusion layer on said organic optoelectronic device, said diffusion layer covers exposed areas of said organic optoelectronic device; an adhesive layer on said substrate and around a perimeter of said diffusion layer, wherein said adhesive layer is separated from said diffusion layer by a gap such that said adhesive layer does not physically contact said diffusion layer; an encapsulation lid on said adhesive layer, said encapsulation lid forming a cavity around said organic optoelectronic device such that there is a gap between said encapsulation lid and said diffusion laver; and a getter on said encapsulation lid, said getter overlies said organic optoelectronic device, wherein said diffusion layer slows a rate of absorption of reactive gasses by said cathode and increases a proportion of said reactive gasses absorbed by said getter relative to said cathode.
