Summary:	有機發光二極體(Organic light-emitting Diode, OLED)為自發光(不需背光源)，相對於薄膜電晶體-液晶顯示器(Thin Films Transistor-Liquid Crystal Display, TFT-LED)擁有許多光電特性的優勢。為了讓OLED達到全彩化平面顯示器的需求，高亮度、高效率、高色純度的RGB三原色，變成為OLED研究發展的重要課題。在本實驗中所使用的主要材料有NPB、CBP、DPVBi、Alq3、CH3(COOH)2Zn、LiF；其中NPB和CBP為電洞傳輸層，DPVBi為藍光發光層，Alq3為電子傳輸層，CH3(COOH)2Zn和LiF為電子注入層。短波長的藍光，在色轉換法(CCM)的全彩技術中扮演重要角色。因此本論文藉由調變各個有機材料的厚度，研究改善藍光OLED的色純度；此外加入雙層CBP做為電洞傳輸層，研究不同厚度的CBP層對元件的影響。為了改善元件電流密度和亮度，加入一適當厚度的額外醋酸類材料可以改善元件藍光色純度、電流密度和亮度。 Organic light-emitting Diode (OLED) emits light itself. It owns many advantages of optical-electronic characteristics as compared with thin films transistor-liquid crystal display (TFT-LCD). In order to achieve the requirement for full color flat panel display, the three primary colors which are red, green, blue (R, G, B) with high luminance, high current efficiency and high color purity are important study of research and development for OLED.In our experiment, the major materials are NPB, CBP, DPVBi, Alq3, LiF and (CH3COOH)2Zn. The materials of NPB and CBP are used as hole transporting layer. DPVBi is blue emission layer. Alq3 is electron transporting layer. LiF and (CH3COOH)2Zn, are used as electron injection layer.The blue light emission with short wavelength plays an important role in color conversion method (CCM) of full color technology. In the study, we improve and research on color purity of blue OLED by various thicknesses of organic layer. In addition, we research the influence of the different thickness of double-CBP layers as hole-transporting layers. In order to improve the current density and luminance, we add extra acetate layer to the device. It can improve the blue color purity, current density and luminance.
