New materials for flexible OLED
For flexible organic light emitting diodes (OLEDs), new materials such as a flexibletransparent conducting electrode and flexible moisture barrier substrate areindispensable. In our laboratory, a new planarized metal-grid transparent electrodefilm has been developed and utilized for the fabrication of the flexible OLED instead ofutilizing the conventional indium tin oxide (ITO) electrode. In addition, for the flexiblemoisture barrier substrates, multi-layered aluminium oxide and polymer substrateswhich can be fabricated by full wet processes have been developed and utilized as theflexible substrates for flexible OLEDs. In order to take the full advantages of flexibleorganic electronics, the new materials are targeted to be possible by the low-cost andshort tact-time processes. These new materials can be applied for the flexible activematrixOLED displays, the flexible OLED lightings, and the flexible organicphotovoltaic (OPV) devices.

New manufacturing processes for flexible OLED and flexible OPV
This research aims to fabricate the flexible OLEDs cheaper and easier than theconventional fabrication processes can. The researches include the solution-baseddeposition of active organic layers, thin film encapsulation processes, and thefabrication of high-efficiency OLED devices. For these researches, besides theconventional vacuum deposition processes for fabricating OLEDs, the unit depositionprocesses such as the atomic layer deposition (ALD), the molecular layer deposition(MLD), the plasma-enhanced chemical vapor deposition (PECVD), the ultrasonic mistdeposition (UMD), and the wet printing processes are utilized. For the wet printingprocesses, the gravure printing and screen printing methods are utilized for thefabrication of flexible OLEDs. We also study a few novel deposition processes tofabricate flexible OLEDs by utilizing the vapour phase polymerization. All the abovefabrication processes can be applied for the fabrication of flexible OPV devices.
