Abstract:
An organic optoelectronic device structure comprising:a polymer substrate layer; a first barrier region disposed over said polymer substrate layer, said first barrier region comprising at least three planarizing layers in an alternating series with at least three other layers, said at least three other layers comprising at least two high-density layers and a layer of material that absorbs water, oxygen or both water and oxygen; a second barrier region disposed over said first barrier region, said second barrier region comprising two or more planarizing layers, two or more high-density layers and a layer of an absorbing material that absorbs water, oxygen or both water and oxygen; and 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, said organic optoelectronic device disposed between said first and second barrier regions, wherein said first barrier region and said second barrier region restrict transmission of water and oxygen from an outer environment to said optoelectronic device.
