Claim Text:
1. A method for encapsulating a substrate having an OLED structure formed thereover, comprising: blanket depositing a first encapsulation layer over the substrate, a contact layer positioned over an upper surface the substrate, and an OLED structure positioned on and in physical contact with the contact layer, wherein the contact layer is positioned below the OLED structure and extends out from under the OLED structure, wherein an upper surface of the contact layer comprises a first portion and a second portion, wherein the OLED structure is positioned on the second portion of the contact layer, and wherein the first encapsulation layer is inorganic; and depositing a second encapsulation layer over the first encapsulation layer above the OLED structure; and blanket depositing a third encapsulation layer over the second encapsulation layer, or over both the first encapsulation layer and the second encapsulation layer; laser ablating at least the first inorganic encapsulation layer to expose the first portion of the upper surface of the contact layer and the upper surface of the substrate.
