Faculty
Dr. George Zhaojun Liu’s research interests include Micro-LEDs, advanced display and AR/VR, GaN Transistors & LEDs, Mass Transferring & Advanced Packaging, Wearable Devices. He is one of the earliest researchers over the world work on Micro-LEDs. He fabricated the first Si CMOS programmed active matrix Micro-LED displays in 2007, the highest PPI Micro-LED displays (till 2016), and the first full-color Micro-LED pico-project in 2012. Dr. Liu has published 60+ journal and conference papers and hold 60+ US & China patents, and delivered 30+ invited talks. Dr. Liu and his team won the second place in the 2011 HKUST One Million Dollar Entrepreneurship Competition. He is a founding member of 2 companies. He is IEEE and SID member, and SID Beijing Chapter Committee member. His research topics include Micro-LEDs, AR/VR, wearable devices, high-density & fine-pitch packaging & mass transferring, low-dimensional material & devices, and flat-panel displays.
