The future developments and prospects of QLED
Dr. Sun obtained his PhD in electronic engineering from the Hong Kong University of Science and Technology. He is presently a Chair Professor and Head of the Department of Electrical and Electronic Engineering in the Southern University of Science and Technology, Shenzhen, China. Before joining Southern University of Science and Technology, he had been working at Nanyang Technological University, Singapore as a Full Professor. He was the Director of Microelectronics Center at Nanyang Technological University. He was awarded the Nanyang Award for Research and Innovation in 2009, the 1000 Talent Award by the Chinese Government in 2012, and the Jacques Beaulieu Excellence Research Chair of INRS, Quebec, Canada in 2013. He is an Academician of the Asia-Pacific Academy of Materials. He is the fellow of several academic societies including OSA, SPIE, SID, and IoP, UK. He is an IEEE Distinguished Lecturer.
Quantum dots (colloidal) are semiconducting nanocrystals, also known as artificial atoms. Due to quantum confinement effect, the emitted color of the QD is directly dependent on the size. With years of study, the start-of-the-art synthesized QDs are known for their high quantum yield and narrow emission bandwidth, making it suitable for practical applications for displays, though there is still some distance for lighting. In this talk, we present highly efficient colloidal core-shell quantum dots, quantum rods and nanoplatelets for emerging energy-saving quality display applications. Especially, we will show a QD composite called QD luminescent microspheres (QLuMis) with high stability suitable for on-chip packaging. We also show unique emission properties of quantum rods and nanoplatelets making them useful in driving display applications. These nanocrystal materials were also used to make high efficiency quantum dot light-emitting diodes with high efficiency. We will touch upon some trends in this field.
