胶体量子点（QD）由于其独特的光学特性，例如尺寸可调的发射波长、窄光谱线宽和接近一致的光致发光量子产率，在显示技术中展现出巨大的潜力。过去十年来，学术界和工业界付出了巨大努力，量子点发光二极管（QLED）的性能取得了显着提高，这主要归功于高质量量子点和优化器件架构的发展。此外，还为量子点开发了复杂的图案化工艺，这是其商业化的关键技术。由于这些成就，一些基于QD的显示技术，例如QD增强膜和QD有机发光二极管，已成功商业化，证实了QD在显示技术中的优越性。然而，尽管取得了这些进展，QLED 的商业化尚未达到门槛，需要在解决挑战和相关问题方面取得飞跃。因此，综述了 QLED 在材料合成、器件工程和制造方法方面的代表性研究趋势、进展和挑战，以明确 QLED 的现状和发展方向。此外，还简要介绍了在对单器件 QLED 进行研究以实现有源矩阵显示器时需要考虑的因素。这篇综述为 QLED 的商业化指明了方向。

Recent Advances and Challenges of Colloidal Quantum Dot Light-Emitting Diodes for Display Applications

Colloidal quantum dots (QDs) exhibit tremendous potential in display technologies owing to their unique optical properties, such as size-tunable emission wavelength, narrow spectral linewidth, and near-unity photoluminescence quantum yield. Significant efforts in academia and industry have achieved dramatic improvements in the performance of quantum dot light-emitting diodes (QLEDs) over the past decade, primarily owing to the development of high-quality QDs and optimized device architectures. Moreover, sophisticated patterning processes have also been developed for QDs, which is an essential technique for their commercialization. As a result of these achievements, some QD-based display technologies, such as QD enhancement films and QD-organic light-emitting diodes, have been successfully commercialized, confirming the superiority of QDs in display technologies. However, despite these developments, the commercialization of QLEDs is yet to reach a threshold, requiring a leap forward in addressing challenges and related problems. Thus, representative research trends, progress, and challenges of QLEDs in the categories of material synthesis, device engineering, and fabrication method to specify the current status and development direction are reviewed. Furthermore, brief insights into the factors to be considered when conducting research on single-device QLEDs are provided to realize active matrix displays. This review guides the way toward the commercialization of QLEDs.
