Abstract

We have developed multi-layer passivation films of UV-polymerized film/inorganic composite film to improve the long lifetime of passivated OLEDs for very thin flat panel applications. Preliminary lifetime to half initial luminance ($L_{o}{\sim}\;3,000\;cd/m^2$) of order 300 Hr is achieved on the conventional encapsulated test pixel using a passive matrix drive at room temperature; 570 Hr lifetime is achieved on a de tested multi-layer passivated 9$mm^2$ test pixel.
