Abstract

An organic electronic device structure, according to a first aspect of the invention, includes: (a) a substrate layer; (b) an organic electronic region disposed over the substrate layer; (c) a pressure sensitive adhesive layer disposed over the organic electronic device; and (d) a barrier layer disposed over the adhesive layer. According to a second aspect of the present invention, an organic electronic device structure includes: (a) a substrate layer; (b) an organic electronic region disposed over the substrate layer; (c) a barrier layer disposed over the organic electronic region; (d) a pressure sensitive adhesive layer disposed over the substrate layer and over the barrier layer; and (e) an additional layer disposed over the adhesive layer. In many preferred embodiments, the organic electronic device region is an OLED region.
