Abstract: |
The package layer for organic electroluminescent device is in one or two sides of the device, and includes thin film layers of alternately superposed polymer material layer and ceramic material layer as well as one thick film layer of organic insulating material on the thin film layer. The thick film layer of organic insualting material can further raise the flexibility and water and oxygen blocking performance of the package, raise mechanical performance of the device, prolong the life of the device and simplify the packing process. The method of the present invention is used for modifying plastic sheet and in preparing flexible sheet with high water and oxygen blocking performance. |
