Abstract Hyperphosphorescent organic light‐emitting diodes (HP‐OLEDs) represent an attractive solution to persistent efficiency roll‐off and device stability issues, combining phosphorescent sensitizers with fluorescent terminal emitters achieve efficient, narrowband emission. This review discusses advances in HP‐OLEDs where the emitter is a multiresonance thermally activated delayed fluorescence compound. Recent breakthroughs performance, including examples demonstrating both high maximum external quantum efficiencies (EQE max ) excellent color purity, are highlighted. summarizes design strategies, challenges, future directions for improving efficiency, stability, spectral performance of HP‐OLEDs.
