Abstract
An edge-sealed, encapsulated environmentally sensitive device. The device includes an environmentally sensitive device, and at least one edge-sealed barrier stack. The edge-sealed barrier stack includes a decoupling layer and at least two barrier layers. The environmentally sensitive device is sealed between an edge-sealed barrier stack and either a substrate or another edge-sealed barrier stack. A method of making the edge-sealed, encapsulated environmentally sensitive device is also disclosed.
Claims31
An edge-sealed, encapsulated environmentally sensitive device comprising:
- a substrate;
- an environmentally sensitive device adjacent to the substrate;
- and
- an edge-sealed barrier stack adjacent to the environmentally sensitive device, the edge-sealed barrier stack comprising a decoupling layer and at least two barrier layers, wherein the decoupling layer has an area, wherein the first barrier layer has an area, and wherein the second barrier layer has an area, the area of the first and second barrier layers being greater than the area of the decoupling layer, and wherein the decoupling layer is sealed between the first and second barrier layers;
- and
- wherein at least one barrier layer of the edge-sealed barrier stack is in contact with the substrate, sealing the environmentally sensitive device between the substrate and the edge-sealed barrier stack forming an environmentally sensitive device seal, wherein an oxygen transmission rate through the environmentally sensitive device seal is less than 0.005 cc/m2/day at 23° C. and 0% relative humidity.
An edge-sealed, encapsulated environmentally sensitive device comprising:
- a substrate;
- an environmentally sensitive device adjacent to the substrate;
- and
- an edge-sealed barrier stack adjacent to the environmentally sensitive device, the edge-sealed barrier stack comprising a decoupling layer and a barrier layer, wherein the decoupling layer has an area, wherein the first barrier layer has an area, the area of the first barrier layer being greater than the area of the decoupling layer;
- and
- wherein the barrier layer of the edge-sealed barrier stack is in contact with the substrate, sealing the environmentally sensitive device and the decoupling layer between the substrate and the barrier layer of the edge sealed barrier stack forming an environmentally sensitive device seal, wherein an oxygen transmission rate through the environmentally sensitive device seal is less than 0.005 cc/m2/day at 23° C. and 0% relative humidity.
A method of making an edge-sealed, encapsulated environmentally sensitive device comprising:
- providing an environmentally sensitive device on a substrate;
- placing an edge-sealed barrier stack adjacent to the environmentally sensitive device, the edge-sealed barrier stack comprising a decoupling layer and at least two barrier layers, wherein the decoupling layer has an area, wherein the first barrier layer has an area, and wherein the second barrier layer has an area, the area of the first and second barrier layers being greater than the area of the decoupling layer, and wherein the decoupling layer is sealed between the first and second barrier layers;
- wherein at least one barrier layer of the edge-sealed barrier stack is in contact with the substrate, sealing the environmentally sensitive device between the substrate and the edge-sealed barrier stack forming an environmentally sensitive device seal, wherein an oxygen transmission rate through the environmentally sensitive device seal is less than 0.005 cc/m2/day at 23° C. and 0% relative humidity.
