Idemitsu Kosan also says that they are working on a new way to 'spray' small-molecule OLED materials. The new method should be ready by 2015. Spraying OLEDs (instead of using vapor-deposition) will mean less material loss, and thus cheaper displays. It will also make it easier to fabricate large panels.
Sumitomo is focusing on blue lifetime, and say that their materials will reach 50,000-60,000 hours by March 2010.
