In the future electronics, all device components will be connected wirelessly to displays that serve as information input and/or output ports. There is a growing demand of flexible and wearable displays, therefore, for information input/output of the next-generation consumer electronics. Among many kinds of light-emitting devices for these next-generation displays, quantum dot light-emitting diodes (QLEDs) exhibit unique advantages, such as wide color gamut, high color purity, high brightness with low turn-on voltage, and ultrathin form factor. Here, we review the recent progress on flexible QLEDs for the next-generation displays. First, the recent technological advances in device structure engineering, quantum-dot synthesis, and high-resolution full-color patterning are summarized. Then, the various device applications based on cutting-edge quantum dot technologies are described, including flexible white QLEDs, wearable QLEDs, and flexible transparent QLEDs. Finally, we showcase the integration of flexible QLEDs with wearable sensors, micro-controllers, and wireless communication units for the next-generation wearable electronics.

在未来的电子产品中，所有设备组件都将无线连接到显示器，用作信息输入和/或输出端口。因此，对于下一代消费电子产品的信息输入/输出，柔性和可穿戴显示器的需求不断增长。在这些下一代显示器的多种发光器件中，量子点发光二极管（QLED）具有独特的优势，例如色域宽，色纯度高，具有低开启电压的高亮度和超薄形式。因素。在这里，我们回顾了用于下一代显示器的柔性QLED的最新进展。首先，总结了器件结构工程，量子点合成和高分辨率全色图案化方面的最新技术进步。然后，描述了基于尖端量子点技术的各种设备应用，包括柔性白光QLED，可穿戴QLED和柔性透明QLED。最后，我们展示了柔性QLED与下一代可穿戴电子设备的可穿戴传感器，微控制器和无线通信单元的集成。
