Perovskite materials show exciting potential for light-emitting diodes (LEDs) owing to their intrinsically high photoluminescence efficiency and color purity. The research focusing on perovskite light-emitting diodes (PeLEDs) has experienced an exponential growth in the past six years. The maximum external quantum efficiency of red, green, and blue PeLEDs has surpassed 20%, 20%, and 10%, respectively. Nevertheless, the current PeLEDs are still in the laboratory stage, and the key for further development of PeLEDs is large-area fabrication. In this paper, we briefly discuss the similarities and differences between manufacturing high-quality and large-area PeLEDs and perovskite solar cells. Especially, the general technologies for fabricating large-area perovskite films are also introduced. The effect of charge transport layers and electrodes on large-area devices are discussed as well. Most importantly, we summarize the advances of large-area (active area ≥ 30 mm²) PeLEDs reported since 2017, and describe the methods for optimizing large-area PeLEDs reported in the literature. Finally, the development perspective of PeLEDs is presented for the goal of highly efficient and large-area PeLED fabrication. It is of great significance for the application of PeLEDs in future display and lighting.

钙钛矿材料因其固有的高光致发光效率和色纯度而显示出令人兴奋的发光二极管（LED）潜力。过去六年来，钙钛矿发光二极管 (PeLED) 的研究呈指数级增长。红色、绿色和蓝色 PeLED 的最大外量子效率分别超过了 20%、20% 和 10%。尽管如此，目前的PeLED仍处于实验室阶段，PeLED进一步发展的关键是大面积制造。在本文中，我们简要讨论了制造高质量和大面积 PeLED 与钙钛矿太阳能电池之间的异同。特别介绍了制备大面积钙钛矿薄膜的通用技术。还讨论了电荷传输层和电极对大面积器件的影响。最重要的是，我们总结了大面积（有效面积≥ 30 mm² ) 自 2017 年以来报道的 PeLED，并描述了文献中报道的优化大面积 PeLED 的方法。最后，提出了 PeLED 的发展前景，以实现高效和大面积 PeLED 制造的目标。这对PeLED在未来显示和照明中的应用具有重要意义。
