Chaoyu Xiang

Chaoyu Xiang, a professor at the Ningbo Institute of Materials Technology and Engineering, Chinese Academy of Sciences, received his Ph.D. in materials science from the University of Florida and has 10 years of R&D experience in organic light-emitting diodes (OLEDs) and quantum dot light-emitting diodes (QLEDs). He has served as director of R&D for new display technologies at Apple, UDC, and TCL, etc., and is now the leader of the Advanced Nano-Optoelectronic Materials and Devices team. He has achieved remarkable results in the research areas of device mechanism, luminous efficiency and lifetime, and has published more than 15 papers as first author in Nature Communications and other SCI journals and has been granted 30 Chinese patents and 4 international patents. He developed the world's first 5-inch and 31-inch full-color AM-QLED prototypes by applying quantum dot passivation and inkjet printing technologies, which were funded by the Chinese Academy of Sciences (CAS) under the "BR Program" and the Zhejiang Provincial Youth Talent Program. Chaoyu Xiang proposed a new idea of reconfiguring the energy level of quantum dots to enhance charge injection, which achieved the million-hour lifetime of QLED devices for the first time. The method of double passivation on the surface of quantum dots also promoted the performance breakthrough of inkjet-printed devices.
