Abstract Two efficient and color‐stable asymmetric hybrid tandem white organic light emitting diode (WOLED) devices have been fabricated with a combination of fluorescent blue and phosphorescent green/red emissive layers. Two different color temperatures of 3000K and 5000K are easily achieved by simply changing the stack order of fluorescent blue and phosphorescent green/red layers. with the help of outcoupling film, high power efficiency of ∼40 lm/W and significantly improved reliability have been achieved.
