| Outline of Final Research Achievements |
In the OLEDs, when expose them to ambient air without any encapsulation layer, a non-emissive spots, i.e., “dark spots”, are grow up with increase an operational time according to low corrosion resistance of low work-function metal, leading to death of the OLEDs. Thus, encapsulation with a high required performance for prevent the penetration of water and oxygen or complexity of the device architecture is believed to be the solutions for preventing a degradation of OLEDs even in air, but these ideas wreak both an increasing of final fabrication time and production cost. Here, we report on that simple but effective approach to toward “low-cost” and “air-stable” OLEDs, in which a utilization of low WF ternary alloy system based on Mg- Ca-Al that had been overlooked during the long years of research on organic electronics.
