Several academic and industrial organizations are developing displays
based on organic electroluminescent (GEL) materials. Once the function
al capabilities and expected lifetimes of organic displays are firmly
established, OEL technology can be used to improve human interfaces in
products such as hand-held terminals. This paper presents optical met
hods for testing the performance and reliability of OEL displays. (C)
