  • Efficiency roll-off in organic light-emitting diodes under elevated current densities not only results in high power consumption but also device degradation. Here, the impact of polaroninduced quenching in efficiency roll-off was investigated and strategies to reduce efficiency roll-off were proposed.

  • OLEDs based on thermally activated delayed fluorescence have shown high fluorescence efficiency but poor lifetime. Herein, Cui et al. demonstrate that the use of n-type host molecules can increase the device lifetime by 30 times and 1000 times for green and blue OLEDs, respectively.

  • Extraordinarily thick organic light-emitting diodes can be fabricated using hybrid organic–inorganic perovskites as the transport layers, thus relaxing fabrication constraints without affecting their efficiency, voltage requirement or durability.
