We demonstrate commercial deposition stable green PHOLED emitter data and incorporate this emitter into two top emission microcavity PHOLEDs that show 110cd/A (NTSC green), and a record high efficiency 160cd/A green, at 3,000cd/m 2 . A new unsaturated green is also presented with a record lifetime of 20,000hrs to LT90 from 2000cd/m 2 .
