It is indeed critical to have a fundamental understanding of how QD properties affect micro-LED display performance in order to develop the most energy-efficient display device in the near future. However, to take a more detailed look at the stability issues and passivation ways of QDs is essential for accelerating the commercialization of QD-based LED technologies. Knowing about the most recent breakthroughs in QD-based LEDs can give a good indication of how they might be used in shaping the future of displays. In this review, we discuss the characteristics of QD-based LEDs for the applications of display and lighting technologies. Various approaches for synthesis and the stability improvement of QDs are addressed in detail, along with recent advancements towards QD-based LED breakthroughs. Moreover, we summarize our latest research findings in QD-based LEDs, providing valuable information about the potential of QD-based LEDs for future display technologies. © 2022 The Royal Society of Chemistry.[SDGs]SDG7Display devices; Energy efficiency; Nanocrystals; Organic light emitting diodes (OLED); Quantum efficiency; Commercialisation; Display performance; Display technologies; Emission linewidth; Energy efficient; Full color; LED display; Lightemitting diode; Property; Stability issues; Semiconductor quantum dotsreview10.1039/d1nr05288h352466722-s2.0-85127291578
