NanoLEDs for AR/VR Microdisplays
Dr. Seth Coe-Sullivan, President, CEO & co-founder of NS Nanotech, Inc.
Presentation Abstract
Dr. Seth Coe-Sullivan will describe NS Nanotech’s new methods for growing nanoLEDs and resulting structures that demonstrate a viable path to overcome current efficiency limits of LEDs for microdisplays and AR/VR displays. The company’s patented technology enables fabrication of components that are smaller and draw less power than current LED solutions, while emitting brighter, more saturated, more stable, and more directional light. NS Nanotech previously announced breakthroughs in green LED performance, with laboratory fabrication of green GaN nanoLEDs that set records for brightness, efficiency, color saturation, directionality, and power consumption, including EQE greater than 11% directly on the wafer. NS Nanotech recently developed red-emitting N-polar InGaN/GaN nanowire heterostructures demonstrating the smallest size red-emitting LEDs ever. The device surface area is nearly three orders of magnitude smaller than some of the previously reported InGaN quantum well red micro-LEDs, and it set a record for efficiency of a submicron-scale red LED, with EQE greater than 1% directly on the wafer. In his talk, Dr. Coe-Sullivan will provide updates on the company’s latest nanoLED performance milestones and discuss the possibilities and potential timelines for delivery of commercial RGB nanoLEDs for AR/VR microdisplays.
Dr. Seth Coe-Sullivan, CEO & Co-Founder, NS Nanotech, Inc.
Seth Coe-Sullivan is co-founder, board member, Chief Executive Officer, and President of NS Nanotech, Inc., a spin-out from the University of Michigan and McGill University with technology developed by Professor Zetian Mi. In January 2020, NS Nanotech was developing future nanoLED products for the next generation of TVs, phones, and computer displays. But when Covid-19 arrived, Dr. Coe-Sullivan knew the company’s extensive experience with nitride semiconductors could help fight the virus. He pivoted the company’s R&D team to development of the NS Nanotech ShortWaveLightTM Emitter, the world’s first solid-state semiconductor device capable of emitting pathogen-neutralizing far-UVC light.
NS Nanotech has exclusive rights to a patent portfolio based on more than a decade of groundbreaking work on nanoLEDs by Prof. Mi at the University of Michigan and McGill. Beyond today’s semiconductor-based far-UVC emitters, the company is developing next-generation nanoscale Gallium-Nitride (GaN) nanoLEDs for UVC disinfection applications, for large displays, and for microdisplays required for augmented reality and virtual reality (AR/VR) applications.
Dr. Coe-Sullivan has a distinguished background in nanotechnology-based solid-state product development. Until 2019 he was Chief Technology Officer of Luminit LLC, where he led R&D and growth through development and introduction of new products. While there he launched the world’s first volume holographic combiner product for augmented reality displays, procuring first customers, completing development, and setting up manufacturing. Before joining Luminit, he was co-founder, board member, and Chief Technology Officer of QD Vision, which was acquired by Samsung. QD Vision’s quantum dot technology is now integrated into Samsung’s QLED televisions.
Dr. Coe-Sullivan received his Ph.D. in Electrical Engineering from the Massachusetts Institute of Technology in 2005, and his Sc.B from Brown University in 1999. He has more than 50 papers, patents, and patents-pending in the fields of organic light emitting devices, quantum dots, displays, and environmental health and safety. He has received many industry awards including Technology Review Magazine’s TR35 Award, BusinessWeek’s top young entrepreneurs, Wall Street Journal’s Innovation Award, the SEMI Award for North America, and the Presidential Green Chemistry Award. Most recently he received the Society for Information Display’s Peter Brody Award for his pioneering work bringing quantum dot technologies to market.
