| 摘要 |
The present invention relates to organic electro-luminescent devices, in particular to methods of increasing device lifetime in organic-electro luminescent devices. We will describe an organic electroluminescent device comprising a substrate, a first electrode layer overlying said substrate, an electroluminescent layer overlying said first electrode layer, a second electrode layer overlying said electroluminescent layer, and an encapsulating layer joined to the substrate to cover the organic electroluminescent layer, wherein said electroluminescent layer is surrounded by a ring of getter material that is disposed in a retaining means provided on or in said substrate and/or said encapsulating layer. |
