WUHAN, China (July 25, 2013) - Wuhan Optoelectronics Forum No. 75 was successfully held in Auditorium A101 at Wuhan National Laboratory for Optoelectronics (WNLO) in the morning of July 25.
In practical applications, the visual contrast of an emissive display is more important than the brightness of image. As such, improving the visual contrast in organic light-emitting diodes (OLEDs) is another important issue to address with a significant technological implication. This talk will discuss the progress in developing gradient refractive index transparent electrode for enhancing the visual contrast in OLEDs. The concept is based upon on using an electrode with a gradient or graded refractive index to minimize the ambient light reflection from OLEDs and hence to enhance the visual contrast. The transparent electrode with gradient refractive index can be easily engineered and optimized during the film deposition, providing a cost-effective approach for application in high contrast OLED displays.
Furong Zhu is a Professor in the Department of Physics and Institute of Advanced Materials (IAM) at Hong Kong Baptist University (HKBU). He received his BSc and MSc in Physics from Fudan University, Shanghai China, in 1983 and 1987. He completed his Ph.D in Applied Physics at Charles Darwin University in Australia from 1990-1993. He did his post-doctoral research in the Department of Electrical and Electronic Engineering at Kyoto University in Japan from 1993-1995, and was a Research Fellow with the Department of Physics at Murdoch University in Australia from 1995-1997 working on silicon thin films derived from plasma enhanced chemical vapor deposition (PECVD) for device application. He joined Institute of Materials Research and Engineering (IMRE) in Singapore in 1997. Prior to HKBU, he was a Senior Scientist and a Program Manager leading the organic light-emitting diode (OLED) and organic photovoltaic (OPV) R&D activities at IMRE. He has authored/co-authored over 90 refereed journal/conference publications, and filed 8 patents in organic electronics. His research interests include device physics, surface science, nanostructures and semiconducting materials-oriented research for application in OLEDs, OPV, thin film transistors and organic sensors. He has been invited to deliver >30 invited talks at the different international conferences.
