Abstract Perovskite light‐emitting diodes (PeLEDs) has emerged as one of the most promising technologies for next generation lighting and high‐definition display applications due to their exceptional color purity, tunable emission, low material costs. In past eleven years, PeLEDs have made remarkable progress researchers come up with many innovative approaches. Among them, additive engineering based on small organic molecules (SOMs) been demonstrated effective strategies enhance external quantum efficiency (EQE) stability PeLEDs. Notably, champion EQEs red, green, blue devices cannot be realized without participation SOMs. Here, this paper first reviews development PeLEDs, followed by a focused discussion specific application mechanism SOMs in Lastly, it analyzes challenges provides an outlook future development.
