Patent number: 8753711Abstract: The present techniques provide systems and methods for protecting electronic devices, such as organic light emitting devices (OLEDs) from adverse environmental effects. The edges of the devices may also be protected by a edge protection coating to reduce the adverse affects of a lateral ingress of adverse environmental conditions. In some embodiments, inorganic materials, or a combination of inorganic and organic materials, are deposited over the device to form a edge protection coating which extends approximately 3 millimeter or less beyond the edges of the device. In other embodiments, the device may be encapsulated with an organic region, and with an inorganic region, or the device may be encapsulated with inorganic materials, which may form the edge protection coating and may be combined with ultra high barrier technology. The coatings formed over the device may extend beyond the edges of the device to ensure lateral protection.Type: GrantFiled: December 18, 2009Date of Patent: June 17, 2014Assignee: General Electric CompanyInventors: Ahmet Gun Erlat, George Theodore Dalakos, Brian Joseph Scherer
