Speaker: Chen Chen, PhD
Dr. Chen Chen is the CEO and co-founder of Saphlux, Inc., an industry leader in quantum dot micro-LED solutions. He has led the company’s efforts in the development and commercialization of three industry-first products: the 4-inch semi-polar (20-21) template for next-generation GaN devices, NPQD® mini-LEDs for commercial displays, and NPQD® micro-LED displays for all-day wearable AR glasses.
Prior to establishing Saphlux, Dr. Chen was an R&D engineer at Schlumberger, where he successfully developed the ONYX360 rolling cutter, which achieved sales exceeding $1 billion and received both the World Oil Award and the E&P Meritorious Award. Holding over 60 patents, Dr. Chen earned his B.S. and Ph.D. in Mechanical Engineering and received his MBA from Yale University.

Abstract:
Quantum dots have long been regarded as the ideal material for superior color performance in displays. However, limitations in efficiency and reliability have restricted their use to low-flux density applications like LCD backlighting and QD-OLED.
To overcome these challenges, Saphlux developed its proprietary NPQD (nanopores with quantum dots) technology. By utilizing electrochemical etching, nanometer-sized pores are formed in gallium nitride, allowing in-situ integration of quantum dots. This innovation significantly improves color conversion efficiency and reliability, enabling two key direct-emitting QD micro-LED applications: NPQD micro-LEDs for public information displays and monolithic full-color AR micro-displays.
