Method for edge sealing barrier films

摘要

A method of making an edge-sealed, encapsulated environmentally sensitive device comprising: providing an environmentally sensitive device on a substrate; depositing a polymeric decoupling layer using a thermal gradient, the polymeric decoupling layer adjacent to the environmentally sensitive device, the polymeric decoupling layer having a discrete area and covering the environmentally sensitive device; and depositing a first barrier layer adjacent to the polymeric decoupling layer, the first barrier layer having an area greater than the discrete area of the polymeric decoupling layer and covering the polymeric decoupling layer, the polymeric decoupling layer being sealed between the edges of the first barrier layer and the substrate or an optional second barrier layer.
