In this paper, we describe a promising way to realize highly efficient fluorescent OLEDs (Organic Light Emitting Diodes) via thermally activated delayed fluorescence (TADF) mechanism. The resultant TADF OLEDs with optimized host‐dopant system showed comparable device performances and surpassed the limits of conventional fluorescent OLEDs.
