At the launch Sherlock commented, “As we strive to embed the knowledge economy in Ireland it is vital that we maximise the return on the significant investment Government is making in research and development. InifiniLED is an excellent example of the type of company that we want to see emerge from this investment. One that will grow, develop and create the jobs this economy needs.”
The Micro LED technology was invented by a team of researchers led by Brian Corbett at Tyndall National Institute, supported and funded by Enterprise Ireland. Under the EI Business Partner Programme, Entrepreneur Joe O’Keeffe, who has already spun out a series of successful companies, evaluated the commercial potential of the Micro LED leading to the launch of the company, InfiniLED.
Portable device manufacturers are continuously in search of new technologies that provide end users with extended battery life, while reducing energy usage. “Our Micro LED technology extends battery life by up five times relative to the current state-of-the-art for any device with an LCD display” commented Joe O’ Keeffe, Interim CEO of InfiniLED.
The Micro LED technology is said to bring performance advantages across a broad spectrum of applications. Already, products have been developed to serve LCD display, medical and analytical instrumentation and maskless lithography markets. InfiniLED is actively seeking new applications, new customers and new licensing opportunities. “We are in the process of raising investment and we invite any interested investors to contact us at
info@InfiniLED.com“, added O’Keeffe.
“This is an excellent example of a successful collaboration between researchers, UCC s Technology Transfer team and external entrepreneurs. We are delighted that Dr. Bill Henry, who as a Tyndall employee worked on indentifying commercial opportunities for the technology, has now joined InfiniLED as Chief Commercial Officer. InfiniLED will continue to access our facilities and expertise in the further development of the Micro

LED technology under an access agreement between InfiniLED and Tyndall”, explained Roger Whatmore, CEO Tyndall National Institute.
InfiniLED is initially targeting three market segments, where it believes its LED s advantages will be most effective. Firstly, in backlighting for mobile phones, TVs and monitors, where the benefits would be reduced energy consumption and extended battery life. The firm is also interested in using its products in analytical and medical instrumentation, where the advantages would be battery life extension and size reduction via simplified heat sinking and the elimination of optics. Finally, InfiniLED is targeting maskless lithography, which can be enabled through the production of micro arrays of LED s
First long wavelength InGaN LED grown on silicon
RSL hopes to commercialise its indium gallium nitride-on-silicon technology in the next 2-3 years and then develop it further for growth on 200mm silicon substrates.
Scientists from RoseStreet Labs (RSL) have demonstrated what they claim is the world’s first long wavelength LED device grown on low cost silicon wafer substrates.
Green and longer wavelength LEDs have been sought after by both science and industry for a long time because they would fill a high-value gap in the rapidly growing global LED market for lighting and illumination where energy efficiency, low cost and miniaturisation are critical product characteristics.
RSL’s breakthrough device compliments its proprietary thin-film InGaN-on-silicon technology for high efficiency photovoltaic applications and power devices. These RSL longer wavelength devices
