Abstract：
Micro-light-emitting diodes (μLEDs), with their advantages of high response speed, long lifespan, high brightness, and reliability, are widely regarded as the core of next-generation display technology. However, due to issues such as high manufacturing costs and low external quantum efficiency (EQE), μLEDs have not yet been truly commercialized. Additionally, the color conversion efficiency (CCE) of quantum dot (QD)-μLEDs is also a major obstacle to its practical application in the display industry. In this review, we systematically summarize the recent applications of nanomaterials and nanostructures in μLEDs and discuss the practical effects of these methods on enhancing the luminous efficiency of μLEDs and the color conversion efficiency of QD-μLEDs. Finally, the challenges and future prospects for the commercialization of μLEDs are proposed.
摘要：
微型发光二极管(μLED),凭借其响应速度快的优势，寿命长,高亮度，和可靠性,被广泛认为是下一代显示技术的核心。然而,由于高制造成本和低外部量子效率(EQE)等问题，μLED尚未真正商业化。此外,量子点（QD）-μLED的颜色转换效率（CCE）也是其在显示行业实际应用的主要障碍。在这次审查中,我们系统地总结了纳米材料和纳米结构在μLED中的最新应用，并讨论了这些方法对提高μLED的发光效率和QD-μLED的颜色转换效率的实际效果。最后,提出了μLED商业化的挑战和未来前景。
