AbstractThe evolution of display technology toward ultrahigh resolution, high color purity, and cost‐effectiveness has generated interest in metal halide perovskites, particularly colloidal perovskite nanocrystals (PeNCs). PeNCs exhibit narrow emission spectra, high photoluminescence quantum yields, and wide color gamuts, rendering them promising candidates for next‐generation displays. Despite significant advancements in perovskite light‐emitting diode (PeLED) technology, challenges remain regarding the efficiencies of PeNC‐based blue LEDs. Addressing these challenges, including both inherent and external instabilities of PeNCs and operational instabilities of the devices, is important as they collectively impede the broader acceptance and utilization of PeNCs. Herein, a comprehensive overview of the syntheses of dimension‐ and composition‐controlled blue colloidal PeNCs and critical factors influencing the performances of colloidal PeNC‐based blue LEDs is provided. Moreover, the advancements of colloidal PeNC‐based blue LEDs and challenges associated with the application of these LEDs are explored, and the potentials of these LEDs for application in next‐generation displays are emphasized. This review highlights the path forward for the future development of PeNC‐based blue LEDs.
