Abstract

An encapsulated organic light emitting device. The device may include a substrate, an organic light emitting layer stack adjacent to the substrate, and at least one first barrier stack adjacent to the organic light emitting device, the at least one first barrier stack comprising at least one first barrier layer and at least one first decoupling layer wherein the at least one first barrier stack encapsulates the organic light emitting device. There may be a second barrier stack adjacent to the substrate and located between the substrate and the organic light emitting device. The second barrier stack has at least one second barrier layer and at least one second decoupling layer. A method of making the encapsulated organic light emitting device is also provided.
