Fabrication and optimization of organic light-emitting devices (OLEDs) (Prof C S Lee)

Since Tang et al. at the Eastman Kodak Company reported the first multi-layered organic light-emitting diode (OLED) with high efficiency, OLED has attracted intense attention because of its enormous potential as flat panel displays (FPD). Comparing to FPD using the conventional LCD technology, OLED has many advantages including wide viewing angles, high contrast, fast response time, high efficiency and potentially low manufacturing costs. In contrast to LCD displays, OLED itself is light emitting. In short, OLED display has the necessary attributes to compete or complement effectively with the LCD technology and to become a major display technology in the near future. Thus, OLED has attracted attention of researchers from academic institutes as well as from industries. On the other hand, as the OLED is still a new technology, many processing techniques have not been fully optimized yet. Thus, the present project aims to work along this direction to explore how performance of OLEDs can be improved by optimizing various processing parameters.
