| 摘 要： | 采用旋转涂布法制备空穴传输层聚二氧乙基噻吩/聚对苯乙烯磺酸过程中,设置高低转速相结合的方式,调转基片方向实施二次旋涂干燥成膜,有效改善了材料因基片开口设计而引起的单双行薄膜厚度不均匀现象. 由于增加了功能层薄膜的均匀性,从而改善了显示屏的整体发光均匀性与发光效率. 改进工艺后制备的绿光显示屏电流效率提高了近40%,并得到了电流效率达1.25 cd/A的96×64的3.81 cm全彩高分子发光点阵显示屏,发光亮度提高了近25%.关键词：旋转涂布法有机发光二极管显示屏

| Abstract: | By improving the spin-coating process during the deposition of hole transport layer poly(3,4-ethylenedioxythiophene)-poly(styrene-sulfonate)(PEDOT:PSS), high efficient monochrome passive-matrix organic light-emitting display is fabricated. The PEDOT:PSS film is spin-coated with a two-step spin-coating process, in which the substrate is turned 180° during the spin-coating, forcing the piled-up materials to move reversely. By introducing the second spin-coating step, the film thickness difference between single and double lines significantly reduces, leading to a more uniform light emission and a larger fill factor for the 3.81 cm monochrome polymer light-emitting diode display. Green light-emitting display with a peak current efficiency of 17 cd/A is successfully fabricated, and the efficiency is improved by 40 percent compared with that made by traditional spin-coating method. A 3.81 cm 96×64 full color display with a current efficiency of 1.25 cd/A is also successfully made. |
