“…At present, some metal ions such as Sn 2+ , Mn 2+ , Tb 3+ , Cu 2+ , In 3+, and Cd 2+ have been used to replace Pb 2+ for constructing lead-free perovskite materials and devices. [174][175][176][177][178][179][180][181][182][183][184] Regrettably, the brightness and EQE of lead-free perovskite devices still lag far behind those of Pb-based devices. In addition, the devices are not well studied in terms of energy level matching and interfacial interaction.…”

Perovskite, as a star fluorescent material, has the characteristics of adjustable luminescence peak, high color purity, high photoluminescence quantum yield, and low cost, showing significant potential in the photoelectric field. Among the RGB colors for display devices, green is the most sensitive color for human eyes, and green perovskite light‐emitting diodes (GPeLEDs) have aroused much interest in recent years. In this work, the research history of GPeLEDs is reviewed, the perovskites of different dimensions are introduced, and the common synthesis methods of perovskites are discussed. Besides, the strategies to improve the stability and luminous efficiency of GPeLEDs are summarized, including component engineering, phase engineering, ligand engineering, additive engineering, interface engineering, and optical coupling structure strategy. Finally, the development state of GPeLEDs is summarized and prospected. This work is expected to stimulate more unprecedented achievements derived from GPeLEDs, thus promoting their practical applications in future ultra‐high‐definition displays.
