Multilayer barrier region containing moisture- and oxygen-absorbing material for optoelectronic devices

An organic optoelectronic device structure comprising:

• a first barrier region;
• a second barrier region;
• and
• an organic optoelectronic device disposed between said first barrier region and said second barrier region, said organic optoelectronic device selected from an organic light emitting diode, an organic electrochromic display, an organic photovoltaic device and an organic thin film transistor,
• wherein said first barrier region and said second barrier region restrict transmission of water and oxygen from an outer environment to said optoelectronic device, and wherein at least one of said first and second barrier regions comprises at least two planarizing layers, at least two high-density layers, and at least one layer of a material that absorbs water, oxygen or both water and oxygen.

An OLED structure comprising:

• a polymer substrate layer;
• a first barrier region disposed over said polymer substrate layer, said first barrier region comprising two or more planarizing layers and two or more high-density layers;
• 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 at least one layer of an absorbing material that absorbs water, oxygen or both water and oxygen;
• and
• an OLED 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.
