This paper has five chapters : the first chapter : describing the evolution of the organic / polymeric electroluminescent device , analyzing its advantages and disadvantages when acting as flat display , introducing the oled structure , luminous mechanics and the methods of increasing the luminous efficiency , etc . the second chapter : discussing the effects on the performance of oled if the lif acts as an electron inject layer and / or cupc acts as a hole inject layer 本文共分五章：第一章：详细叙述了有机聚合物电致发光器件的研究进展，分析了其作为平板显示的优缺点，介绍了oled结构、发光原理和提高其效率的途径等。第二章：讨论了lif作为电子注入层， cupc作为空穴注入层对器件性能的影响。
Since the discovery of cnt ’ s and find that cnts have small diameter and high length diameter ratio and can be look as one - demission material , it can be used as emission emitter of fed . especially , the aligned cnts array can be seen innumerable single cathodes which are lined regularly and form array . so growing aligned cnts array in selective area is the key technology to product cnts fed , which is also the necessary condition of cnts micro - electronics device 自碳纳米管发现以来,由于碳纳米管的直径很小、长径比大,故可视为准一维纳米材料,可作为场发射平板显示的尖端发射体,特别是定向碳纳米管阵列可看成是无数根单尖阴极规则的排列起来形成阵列式,是理想的场发射平板显示器的尖端发射体。
