摘要
描述了薄膜场致发光（ＴＦＥＬ）显示的电学和光学性质．介绍了夹层结构，它等效于齐纳二极管组成的线路．分析了影响亮度和效率的因素，主要是发光中心浓度、电子的能量和发光体的结晶状态．为了提高电子能量，提出了分层优化方案，它具有明显的优越性；为改善发光层的结晶状态，提出了厚膜场致发光（ＴＤＥＬ）．对场致发光的机理进行了讨论，描述了多色和全色ＴＦＥＬ器件的材料和结构的研究进展．
The electrical and optical properties of thin film electroluminescence (TFEL)displays are described.A simple Zener model for TFEL devices is used to discuss the factors influencing luminance and efficiency,from which it is concluded that the layered-optimization structure has the most advantages,and a thick dielectric electroluminescence device can improve the crystallinity of phosphor.The basic mechanism of TFEL devices is described.The development and prospects of multi color and full color electroluminescence flat panel displays are reviewed.
