In Byeong Kang received his B.S. and M.S. degrees in Electronic Engineering from Hanyang University, Seoul, Korea, in 1989 and 1991, respectively. He also received his Ph.D. degree in Electronic Engineering from the University of South Australia in 1998. He subsequently joined LG Display, Korea, as a engineer in 1991, where he worked on the design and characterization of display for various applications such as IT, TV, and Mobile. He served as CTO, executive vice president, in LG Display from 2014 to 2020, leading technology research and development of future flat panel display such as TFT¿LCD, AMOLED, and flexible display. In particular, he has led development of rollable OLED TV, transparent signage OLED, and 8K UHD OLED TV. He has published more than 30 co-authored international journal papers and 130 international conferences. He has also presented many talks at major display conference including keynote speech. He is a fellow of The Society for Information Display.Now, he is also a regular member of The National Academy of Engineering of Korea. Chang Wook Han is the head of OLED device technology department as a chief research fellow and a vice president in LG Display, Korea. He obtained his B.S. and M.S. degrees in Material Science from Seoul National University, Korea, in 1987 and in 1989, respectively. He also received Ph.D. degree in Electrical Engineering from Seoul National University, in 2007. The title of his Ph.D. thesis was "a-Si:H TFT and pixel structure for AMOLED on flexible metal substrates". Since joining LG Display in 1990, he has worked on the device and process development on a-Si:H TFT backplanes for AMLCD. He has also focused on enhancing the performance of OLED device and developing new OLED panel structure since 1999. In particular, he has led several projects that have developed tandem white OLED and encapsulation technology for TV. He has experienced the successful application of these technologies to theworld's first 55-inch OLED TV and transparent OLED products. His research achievements were recognized and he was presented the LG Group's R&D Grand Award, in 2013. He has also developed the innovated white OLED devices to meet the requirement for 4K and 8K OLED TV. Recently, he is in charge of developing TADF, blue phosphorescence, self-emitting QLED, and cultivating new OLED device for AR/VR micro-display. He has published more than 16 authored international journal papers and 30 international patents on flat panel display. He has published 4 authored chapters of book. He has also presented over 20 talks at major display conference including invited talks. He has served The Society for Information Display and International Meeting on Information Display conference as a program committee member on OLED. Jae Kyeong Jeong received his B.S., M.S., and Ph.D. degrees in material science and engineering from Seoul National University, Seoul, Korea, in 1997, 1999, and 2002, respectively. In 2003, he was a postdoctoral researcher at the University of Illinois at Urbana-Champaign. In 2004, he joined Samsung Mobile Display Corp. as a senior engineer, where he had focused on the design and development of Si and amorphous IGZO TFTs for AMOLED display. In 2008, he successfully developed the world's largest 12.1" Oxide TFT-driven AMOLED display as a project leader. In 2009, he joined Inha University Incheon, Korea, as an assistant professor, where he had continued the oxide semiconductor and related field-effect transistors. Since September 2015, he is with the Department of Electronic Engineering at Hanyang University as a professor. His research group is interested in next-generation display electronics, CMOS TFTs for IoT, stretchable electronics, and emerging semiconductor devices. He has published more than 163 authored (or co-authored) international journal papers and 112 international patents. His total citation number and h-index are 21,498 and 56, respectively, according to the latest scholar google search. Also, he is currently an editorial board member of Scientific Reports and Journal of Information Display.
