Abstract

An organic optoelectronic device structure and a method of making the same. The structure comprises: (a) a first barrier region comprising (i) a first composite layer stack and (ii) a second composite layer stack attached to the first composite layer stack, (b) an organic optoelectronic device selected from an organic light emitting diode, an organic electrochromic display, an organic photovoltaic device and an organic thin film transistor; and (c) at least one additional barrier region, wherein the at least one additional barrier region cooperates with the first barrier region to restrict transmission of water and oxygen to the optoelectronic device from an outer environment. The first composite layer stack in this structure comprises a first polymer substrate layer, at least one first planarizing layer and at least one first high-density layer, while the second composite layer stack similarly comprises a second polymer substrate layer, at least one second planarizing layer and at least one second high-density layer.
