Inaugural Lecture of IAS Professor

The Evolution of the Next-generation Display Technology


It has taken nearly three decades for the organic light emitting diode (OLED) to emerge from a laboratory curiosity to a premier technology with the potential to revolutionize the display industry and to enable new electronic products. From the inventor’s viewpoint, Prof Tang will trace the development of OLED from the early discovery to recent commercialization. He will present an outlook of OLED as well as the challenges as it is poised to become the next-generation display technology.

About the speaker

Prof. Ching W. Tang’s research interests lie in the general areas of Chemical and Condensed Matter Physics, and in particular in organic electronics. He has been recognized for the invention of the high-efficiency Organic Light Emitting Diodes (OLED). Internationally known as “Father of OLED”, the Hong Kong born and raised Prof Tang is the first Chinese recipient of the highly reputable Wolf Prize in Chemistry (awarded in 2011). The award is for his discovery of OLED, which is starting to replace Liquid Crystal Display (LCD) in smart phones, computers, and televisions. The Wolf Prizes in physics and chemistry are often considered the most prestigious awards in those fields after the Nobel Prize. Based on this key invention, a superior flat-panel display technology has been developed for electronics display applications from cellular phones to large-area high-definition television screens. Prof Tang has also been recognized for the discovery of the organic hetero-junction diode. This discovery has been recognized as a milestone contribution to the field of organic electronics and opto-electronics. The hetero-junction device structure has been found to be the key to obtaining high performance in organic-based, thin film devices including OLED and solar cells.

Prof. Tang received his PhD in Physical Chemistry from Cornell University in 1975. He then worked in Eastman Kodak and was named Distinguished Fellow of the Kodak Research Laboratories in 2003. He joined the University of Rochester as the Doris Johns Cherry Professor of Chemical Engineering in 1996, and has joint appointments in the Department of Chemistry and the Department of Physics and Astronomy.

Prof. Tang was elected to the fellowship of the American Physical Society in 1998, and membership of the US National Academy of Engineering in 2006. He has received honorary degrees from Shanghai University, and South China Technology University. In addition to the Wolf Prize in Chemistry, Prof Tang has received many other awards including the Eastman Kodak Innovation Award (2000), the Jack Rajchman Prize of the Society of Information Display (2001), the Carothers Award of the American Chemical Society (2001), the Rochester Law Association Inventor of the Year Award (2002), the Humboldt Research Award (2005), the Daniel E. Noble Award (2007) and the Eduard Rhein Award (2013).
