Perovskite light-emitting diodes toward commercial full-color displays: Progress and key technical obstacles

Perovskite light-emitting diodes (PeLEDs) have been considered the most potential application technologies for the next-generation display and lighting field. Since the first room temperature-emission PeLED was demonstrated in 2014, the performances of PeLEDs have improved rapidly within a few years. The external quantum efficiencies (EQEs) of green, red, and near-infrared emission devices have exceeded 20%.
