Professor of The University of Strathclyde, UK

Martin Dawson is a Distinguished Professor at the University of Strathclyde, Glasgow, UK, and serves as Director of Research at the University’s Institute of Photonics, which he helped establish almost 25 years ago. He is also, since 2012, the inaugural Head of the UK’s first Fraunhofer Research Centre, the Fraunhofer Centre for Applied Photonics. Prof. Dawson is known for the breadth of his work on semiconductor optoelectronics, from fundamentals to devices to applications, in areas including gallium nitride, optically-pumped semiconductor lasers and diamond photonics, and he has published almost 900 refereed journal and conference papers. His group is widely recognised for pioneering contributions to micro-LED technology over the past 20 years, including commercial development though the establishment of mLED Ltd, acquired by Oculus in 2016. Prof. Dawson holds fellowships of IEEE, OSA, UK Institute of Physics (IOP) and the Royal Society of Edinburgh and he has received awards including the IOP Dennis Gabor Medal and Prize and the IEEE Photonics Society’s Aron Kressel Award.

Oral Presentation: Micro-LEDs for Technological Convergence between Displays, Optical Communications,Sensing and Imaging

Abstract: Micro-pixel light emitting diode (micro-LED) technology, based primarily on gallium nitride semiconductor materials, is now developing rapidly towards commercialisation for new forms of electronic visual displays. These displays are variously scalable from micro-displays and wearables up to large panels, and offer high brightness, high resolution and fast response, facilitated by both the physical characteristics of the semiconductor micro-pixels and their suitability for integration with backplanes based on advanced electronic technologies such as CMOS. This intimate connection between high-performance displays and sophisticated electronic control is facilitating other emerging applications including visible light communications and sensing and imaging functions. Thus micro-LEDs are fostering new technological convergences by which displays are becoming interactive with their environment. In this presentation, we review the pertinent characteristics of CMOS-interfaced micro-LEDs and illustrate their applications beyond traditional ‘direct view’ visual displays.
