有机电致发光器件薄膜封装研究进展

摘要

有机电致发光器件(OLEDs)对水汽和氧气非常敏感,渗入OLEDs内的水汽和氧气会腐蚀有机功能层及电极材料,严重影响器件寿命.文中根据OLEDs对封装材料的要求,分析了目前最有前景的OLEDs封装技术——薄膜封装,重点介绍了薄膜封装的分类和研究现状.%Organic light-emitting devices (OLEDs) are extremely sensitive to vapor and oxygen. The influence of inleakage of vapor and oxygen which can corrode organic functional layer and the electrode material on device's lifetime was serious. Based on the requirements of encapsulation materials, this paper analyzes the most promising OLEDs encapsulation technology -thin film encapsulation, which mainly focuses on the classification and research status.
