Abstract

ABSTRACT Nowadays, flexible organic light-emitting diodes (OLEDs) have been widely used in next-generation wearable electronics. Flexible electrodes, flexible substrates, and flexible encapsulation are indispensable components for the construction of flexible OLEDs. In this review, metal nanowires and graphene-based flexible electrodes, textile (fiber and fabric), novel polymer film-based flexible OLEDs, including the key process of planarization for flexible OLEDs fabrication on uneven surfaces are discussed. OLEDs cannot operate stably without encapsulation in an ambient atmosphere. Not only barrier performance but also mechanical properties are necessary for the encapsulation of flexible OLEDs. The encapsulation technologies for flexible OLEDs fabrication are also described.

可穿戴器件柔性oled研究进展

目前，柔性有机发光二极管(oled)已广泛应用于下一代可穿戴电子产品中。柔性电极、柔性衬底和柔性封装是柔性oled结构不可缺少的组成部分。本文综述了金属纳米线和石墨烯基柔性电极、纺织(纤维和织物)、新型聚合物薄膜基柔性oled，包括在不平整表面上制造柔性oled的关键工艺。如果没有封装，oled在环境气氛中无法稳定运行。柔性oled的封装不仅需要阻隔性能，还需要机械性能。本文还介绍了柔性oled的封装技术。

期刊介绍： Fiber and Integrated Optics , now incorporating the International Journal of Optoelectronics, is an international bimonthly journal that disseminates significant developments and in-depth surveys in the fields of fiber and integrated optics. The journal is unique in bridging the major disciplines relevant to optical fibers and electro-optical devices. This results in a balanced presentation of basic research, systems applications, and economics. For more than a decade, Fiber and Integrated Optics has been a valuable forum for scientists, engineers, manufacturers, and the business community to exchange and discuss techno-economic advances in the field.
