Abstract： |
The organic electroluminescence device (OELD) includes packaging structure. The packaging structure includes a layer of thick film formed from polymeric material. Dryer is doped in the layer of thick film. The dryer includes alkali metals, alkaline earth metal and at least one object selected from following matters: metallic oxide, zeolite, and metal alcoholates with hydrocarbon in long chain, sulfate, halide, and perchlorate. The packaging structure is located at one side or two sides of OELD. The invention simplifies packaging technique, reduces defects in preparing procedures, raising flexibility and performance for obstructing water and oxygen so as to raise service life of device. |
