White emitter systems are studied in OLED using doped charge transport layers. Mature fluorescent white diodes combining high efficiency with lifetimes exceeding 10,000h at a brightness of 1000 cd/m 2 are reported. Stacked devices for applications requiring a high color rendering index perform at a current efficiency of 80 cd/A and power efficiency of 23 lm/W at 1000 cd/m 2 with the lifetime exceeding 10,000h at 1000 cd/m 2 . Efforts towards top‐emission white OLED and white OLED for passive matrix applications yield promising results.
