NS Nanotech, a LED materials company startup announced its first technical milestone with the demonstration of a nano-LED that promises to close the “green gap” in LEDs.
The new LED technology is based on patented technology enabling fabrication of components that will be smaller and draw far less power than current LED solutions, while emitting brighter, more saturated, more stable, and more directional green light. The demonstration unit is now showing at the virtual Display Week until today.

Seth Coe-Sullivan, CEO and co-founder, said, “Initially, we are bridging the ‘green gap’ in LEDs that has drastically limited their use in markets ranging from large-scale outdoor signage to mobile displays. Ultimately, we intend to disrupt even larger emerging markets for multicolor Micro LED displays and UV LED solutions.”

Based on exclusively licensed patent portfolios from McGill University and the University of Michigan, NS Nanotech’s technology introduces new methods for growing nano-LEDs and their resulting structures. Coe-Sullivan said the company’s green LED technology is expected to deliver an order-of-magnitude improvement in efficiency for micron-sized devices, from today’s standard of less than 5% to more than 50% wall-plug efficiency (Wopt/Welec). The company has achieved nano-LED performance of less than 5nm FWHM (full width at half maximum) emission spectrum.
The company intends to bring costs below the threshold required for integration of micro-LEDs into countless end products. NS Nanotech expects its green LED wafer will offer twice the efficiency performance of any other current solution. Further development will enable breakthroughs in cost and efficiency delivering performance equivalent to chips that today are ten times the size, for products such as Micro LED displays used in mobile phones.
NS Nanotech’s nano-LEDs will also be capable of delivering invisible ultraviolet-spectrum light that has been proven effective in water and air purification and sterilization of medical equipment. By delivering to UV LEDs the same breakthroughs in cost and performance that it delivers to multicolor micro LEDs, the company will be positioned to enable new classes of antiviral and anti-microbial purification solutions.
