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.
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.
