摘要:
柔性量子点发光二极管（QLEDs）不仅具备其刚性量子点器件高效发光特性，如高色纯度、宽色域、低驱动电压、能耗低和高发光效率等，还兼顾柔性电子的可弯曲折叠、轻质超薄、便携性和贴合性等特征，在新型显示、可穿戴和可植入式光电子领域展现出重要应用前景。然而，柔性QLEDs与刚性器件相比还存在效率低和稳定性差等问题，主要归因于柔性衬底与功能层的界面缺陷多、电荷注入势垒高等问题，急需发展新型柔性导电衬底和界面修饰策略。首先概述了柔性QLEDs的器件结构和发展历程，然后分析比较了不同柔性基底与透明电极的优缺点；详细介绍了通过功能层优化与界面工程方面研究工作实现高性能柔性QLEDs的进展。接着，进一步概述了柔性QLEDs在可穿戴显示、柔性照明、便携式光疗等领域的应用发展。最后，就柔性QLEDs的现存问题及未来发展进行了讨论和展望。
Abstract:
Flexible quantum dot light-emitting diodes (QLEDs) not only possess the high-efficiency light-emitting characteristics of rigid QLEDs counterparts, such as high color purity, wide color gamut, low drive voltage, low power consumption, and high light-emitting efficiency, but also incorporate the features of flexible electronics, including bendability, foldability, lightweight and ultra-thin design, portability, and conformability. As a result, flexible QLEDs hold significant application potential in the fields of next-generation displays, wearables, and implantable optoelectronics. However, compared to rigid QLEDs devices, flexible QLEDs still suffer from issues such as low efficiency and poor stability, primarily attributed to numerous interface defects between the flexible substrate and the functional layer, as well as high charge injection barriers. There is an urgent need to develop novel flexible conductive substrates and interface modification strategies. This review first outlines the fundamental device structure and development history of flexible QLEDs, then analyzes and compares the advantages and disadvantages of different flexible substrates and transparent electrodes, details functional layer optimization and interface engineering research and progress for achieving high-performance flexible QLEDs. Subsequently, the paper further outlines the application developments of flexible QLEDs in fields such as wearable displays, flexible lighting, and portable phototherapy. Finally, it discusses and provides an outlook on the existing challenges and future development directions of flexible QLEDs.
