碩士 === 國立交通大學 === 顯示科技研究所 === 94 === Inverted Organic Light-Emitting Device（IOLED）has great potential to be integrated with a-Si TFT and applied in large active-matrix OLED displays. In order to get good performance, we have developed a highly efficient IOLED in which the barrier height between indium tin oxide (ITO) and organic electron transport material has been reduced by different electron injection materials. The mechanism of electron injection can be rationalized by the formation of interfacial dipole and trap states. By using Mg/Cs2CO3: Bphen as electron injection bi-layer, the device of IOLED can achieve not only high performance but also more stable device than those of the conventional OLED.
