It is demonstrated that materials with thermally activated delayed fluorescence (TADF) are ideal host materials for organic light‐emitting diodes (OLEDs). TADF‐sensitized‐fluorescent OLEDs exhibit maximum power efficiency up to 45 lm/W. TADF‐sensitized‐phosphorescent OLEDs show high efficiency, low voltage and long lifetime even at low phosphor concentrations of <3 wt%.
