Abstract
An edge-sealed barrier film composite. The composite includes a substrate and at least one initial barrier stack adjacent to the substrate. The at least one initial barrier stack includes at least one decoupling layer and at least one barrier layer. One of the barrier layers has an area greater than the area of one of the decoupling layers. The decoupling layer is sealed by the first barrier layer within the area of barrier material. An edge-sealed, encapsulated environmentally sensitive device is provided. A method of making the edge-sealed barrier film composite is also provided.
Claims16
An edge-sealed barrier film composite comprising:
- a substrate;
- at least one initial barrier stack adjacent to the substrate, the at least one initial barrier stack comprising at least one decoupling layer and at least one barrier layer, wherein a first decoupling layer of a first initial barrier stack has an area and wherein a first barrier layer of the first initial barrier stack has an area, the area of the first barrier layer of the first initial barrier stack being greater than the area of the first decoupling layer of the first initial barrier stack, and wherein the first barrier layer of the first initial barrier stack is in contact with the substrate or a third barrier layer of the first initial barrier stack, sealing the first decoupling layer of the first initial barrier stack between the first barrier layer of the first initial barrier stack and the substrate or the third barrier layer of the first initial barrier stack;
- an environmentally sensitive device adjacent to the at least one initial barrier stack on a side opposite the substrate;
- and at least one additional barrier stack adjacent to the environmentally sensitive device on a side opposite the substrate, the at least one additional barrier stack comprising at least one decoupling layer and at least one barrier layer, wherein a first decoupling layer of the first additional barrier stack has an area and wherein a first barrier layer of the first additional barrier stack has an area, the area of the first barrier layer of the first additional barrier stack being greater than the area of the first decoupling layer of the first additional barrier stack, wherein the first barrier layer of the first additional barrier stack is in contact with a third barrier layer of the first additional barrier stack, sealing the first decoupling layer of the first additional barrier stack between the first barrier layer of the first additional barrier stack and the third barrier layer of the first additional barrier stack, and wherein at least one barrier layer of at least one initial barrier stack is in contact with at least one barrier layer of at least one additional barrier stack, sealing the environmentally sensitive device between the at least one initial barrier stack and the at least one additional barrier stack.

An edge-sealed, encapsulated environmentally sensitive device comprising:
- at least one initial barrier stack comprising at least one decoupling layer and at least one barrier layer, wherein a first decoupling layer of a first initial barrier stack has an area and wherein a first barrier layer of the first initial barrier stack has an area, the area of the first barrier layer of the first initial barrier stack being greater than the area of the first decoupling layer of the first initial barrier stack, and wherein the first barrier layer of the first initial barrier stack is in contact with a third barrier layer of the first initial barrier stack or an optional substrate, sealing the first decoupling layer of the first initial barrier stack between the first barrier layer of the first initial barrier stack and the third barrier layer of the first initial barrier stack or the optional substrate;
- an environmentally sensitive device adjacent to the at least one initial barrier stack;
- and at least one additional barrier stack adjacent to the environmentally sensitive device on a side opposite the at least one initial barrier stack, the at least one additional barrier stack comprising at least one decoupling layer and at least one barrier layer, wherein a first decoupling layer of a first additional barrier stack has an area and wherein a first barrier layer of the first additional barrier stack has an area, the area of the first barrier layer of the first additional barrier stack being greater than the area of the first decoupling layer of the first additional barrier stack, wherein the first barrier layer of the first additional barrier stack is in contact with a fourth barrier layer of the first additional barrier stack, sealing the first decoupling layer of the first additional barrier stack between the first barrier layer of the first additional barrier stack and the fourth barrier layer of the first additional barrier stack, and wherein at least one barrier layer of at least one initial barrier stack is in contact with a least one barrier layer of at least one additional barrier stack, sealing the environmentally sensitive device between the at least one initial barrier stack and the at least one additional barrier stack.
