摘　　要：基于有机电致发光器件的能级结构,阐述电极薄膜优化对提高载流子注入效率的作用。系统评述了红绿蓝三原色有机发光材料在荧光量子效率、稳定性、寿命等方面的进展。在对比分析有机显示器件被动矩阵和主动矩阵两种驱动方式技术特点的基础上,介绍了主动矩阵的薄膜晶体管TFT驱动电路的研究进展及相关技术难点。最后简要回顾有机面板在显示尺寸、色彩及寿命方面的研发成果,并探讨了大尺寸面板在产业化进程中面临的问题及可能的技术解决方案。Based on the energy-level structure of Organic Electroluminescent （OEL） devices, the effect of the electrode modification on the improving to cartier injection efficiency is analyzed. Then, the tricolor luminous materials are reviewed about their quantum efficiency, luminous stability, lifetime and so on. After analysis to the technical characteristics of the two driving methods of OEL Display（ OELD）, passive matrix driving and active matrix driving, the progresses and technical difficulties of the Active Matrix（AM） driving are introduced, which is carried out by the Thin Film Transistor （rIFT） array. Finally, the new research achievements on the display size, color, and lifetime of OELD are presented. Moreover, the problems faced by large-size OELD in the industrialization and the probable solving methods are also discussed.
