OLED inventor joins QD Vision science advisory board
The innovator of Quantum Light product platform harnesses the unique light-emitting properties of a new class of nanomaterials called quantum dots
Ching Tang, inventor of the organic light emitting diode (OLED) and a winner of the prestigious Wolf Prize in the field of chemistry, has joined QD Vision on the company’s scientific advisory board.
cited by more scientists than any other papers published in the history of the journal.
Tang is a member of the National Academy of Engineering.
“QD Vision’s leadership in the commercialisation of quantum dot materials, and its ground breaking research into electroluminescent applications of the technology, is really impressive” says Tang. “I am truly excited to be joining this world-class team of scientists and engineers in the field of nanotechnology.”
Kyma saving energy with new funding
The supplier of crystalline III-nitride semiconductor materials including GaN, AlN, AlGaN and related products and services, has received funding from the NC Green Business Fund
Kyma Technologies is making energy saving measures to complete in 2011, one of the largest geothermal HVAC systems for cleanroom air handling in North Carolina.
Funded by the North Carolina Green Business Fund, Kyma contracted TriMech to install a 30 ton geothermal HVAC system and a 20 ton energy efficient industrial chiller. The company also enlisted Danco Electrical Contractors to install energy efficient lighting and Kyma itself also installed a facility- wide data acquisition system for energy usage analysis and optimisation.
Kyma estimates that the energy needed to run the facilities for its cleanroom has been reduced by 68% and that overall energy usage of the company has been reduced by 35%.
Ching Tang, Scientific Advisor, QD Vision
Currently the Doris Johns Cherry Professor at the University of Rochester, Tang is credited with several key innovations that led to the commercialisation of OLED flat-panel display technology, including the discovery of the basic heterojunction device structure.
“Ching Tang is an extraordinary talent and we are thrilled to have him join Professor Vladimir Bulovic and Professor Moungi Bawendi on QD Vision’s three-member scientific advisory board,” says Seth Coe-Sullivan, QD Vision founder and Chief Technology Officer.
“His creation of the OLED and organic photovoltaic fields has shaped 25 years of research and technology around the world, changing how we display information and harvest solar energy. We look forward to him having a similar impact on our quantum dot devices in the lighting and display markets.”
In addition to the Wolf Prize, Tang has received numerous industry awards. These include, the Daniel E. Noble Award, which recognises outstanding contributions to emerging technologies, the Humboldt Research Award, and the Jan Racjhman Prize from the Society for Information Display. His seminal paper on OLED technology was published in 1987 in the journal Applied Physics Letters, and is said to have been

In addition to immediate energy savings, the data acquisition system will allow continued analysis of other energy-consuming systems to identify additional energy savings opportunities.
The geothermal HVAC unit controls all of the air handling for Kyma’s class 10,000 (ISO 7) cleanroom, and maintains stringent temperature and humidity requirements with 25 air changes per hour using 100% outside air. This unit is one of the largest geothermal units in the state of North Carolina and is claimed to be the only one that uses 100% outside air.
Addison provided the custom HVAC unit that is uniquely designed for parameters outside the normal design space. Kyma is continuing to work with TriMech and Addison engineers to monitor and optimise the operation of the machine.
According to Paul Penland, President of TriMec, “The end results of this very unique and challenging project were very satisfying. This is the only known geothermal heat pump in the state using 100% outside air, and we are breaking new ground in showing that this type of system works and is very energy- efficient.”
Heather Splawn, Chief Operating Officer and Director of Business Development who led the project for Kyma, adds “This project has helped us to significantly lower our costs
