We show that efficiency, voltage and lifetime cannot be optimized simultaneously in blue fluorescent OLEDs. With novel ETMs, any desired trade-off In performance can be obtained. In an optimized system, 8.5% EQE were achieved. With thick ETLs, we obtain low driving voltage and improved color purity in green phosphorescent OLEDs.
