Efficient Organic Light Emitting-Diodes (OLEDs)

Following two decades of intense research globally, the organic light-emitting diode (OLED) has steadily emerged as the ultimate display technology of choice for the coming decades. Portable active matrix OLED displays have already become prevalent, and even large-sized ultra-high definition 4K TVs are being mass-produced. More exotic applications

Yi-Lu Chang received his BASc in engineering physics from the University of British Columbia, Vancouver, Canada, in 2007, and MEng in electrical engineering from McGill University, Montreal, Canada, in 2009, where he specialized in molecular beam epitaxial growth of group III-nitride nanowires and their applications in light-emitting diodes. In 2014, he received his PhD in materials science and engineering from the University of Toronto, Canada, where he focused on the development of efficient organic light-emitting diodes (OLEDs) for displays and solid-state lighting. Currently, Dr. Chang is vice president of research at OTI Lumionics Inc., which specializes in the development of novel OLED products for general lighting and displays.
