Ching Wan Tang (Chinese: 鄧青雲; pinyin: Dèng Qīngyún; born July 23, 1947) is a Hong Kong–American physical chemist. He was inducted into the National Inventors Hall of Fame in 2018 for inventing OLED (together with Steven Van Slyke), and was awarded the 2011 Wolf Prize in Chemistry.[1] Tang is the IAS Bank of East Asia Professor at the Hong Kong University of Science and Technology and previously served as the Doris Johns Cherry Professor at the University of Rochester.[2][3]


Tang was born in Yuen Long, British Hong Kong in 1947. He attended secondary school at Yuen Long Public Secondary School in Hong Kong and later received his senior high school education at King's College. He graduated with a BS in chemistry from the University of British Columbia, Canada, and subsequently earned his PhD in physical chemistry from Cornell University in the US in 1975.[4] He joined Eastman Kodak in 1975 as a Research Scientist, was promoted to Senior Research Scientist in 1981, to Research Associate in 1990, and to Senior Research Associate in 1998. In 2003 he was named Distinguished Fellow of the Kodak Research Laboratories, Eastman Kodak Company. In 2006 he joined the University of Rochester as the Doris Johns Cherry Professor.

Tang is the inventor of several groundbreaking electronic devices, including the OLED (organic light-emitting diode),[5] and the hetero-junction organic photovoltaic cell (OPV).[4] Efficient OLEDs of small molecules were first developed by Tang at the research department of Eastman Kodak Company in the 1970s. Tang is widely recognized as one of the leaders in the organic electronics industry and in photovoltaics.[6] Tang was elected to the National Academy of Engineering in 2006 for "the invention of the organic light-emitting device and organic bilayer solar cell, the bases of modern organic electronics".[7]

In addition to his pioneer research on the OLED and OPV, Tang made a number of critical innovations resulting in the commercialization of a new flat-panel display technology. These innovations include "the development of robust transport and luminescent materials, improved device architectures, novel color pixilation methods, and fabrication processes for the manufacture of passive-matrix OLED displays; and the adaptation of active-matrix backplane technology for high-definition OLED displays".[8]

On 15 February 2011, Tang was awarded the Wolf Prize in Chemistry, together with Stuart A. Rice and Krzysztof Matyjaszewski. The official citation for the three professors from the Wolf Foundation reads: "For deep creative contributions to the chemical sciences in the field of synthesis, properties and an understanding of organic materials; for exploring the nature of organic solids and their energy profiles, structure and dynamics and for creating new ways to make organic materials, ranging from polymers, to organic-based devices that capture energy from the sun, and light our way in the dark; and for groundbreaking conceptual and experimental advances that have helped to create the research field of organic materials." [9]

On 5 December 2015, Tang was elected a founding member of the Academy of Science of Hong Kong.
