    摘要: Methods of making an edge-sealed, encapsulated environmentally sensitive device. One method includes providing an environmentally sensitive device with a contact on a substrate; depositing a decoupling layer adjacent to the environmentally sensitive device, the decoupling layer having a discrete area and covering the environmentally sensitive device and not covering the contact, the decoupling layer deposited using a printing process; depositing a first barrier layer adjacent to the decoupling layer, the first barrier layer having a first area greater than the discrete area of the decoupling layer, and the first barrier layer having a second area covering the decoupling layer and the contact, the decoupling layer being sealed between the edges of the first barrier layer and the substrate or an optional second barrier layer; and removing the second area of the first barrier layer from the contact.
