University of Toronto engineers have combined two promising solar cell materials together for the first time, creating a new platform for LED technology. The team has designed a way to embed the strongly luminescent nanoparticles called colloidal quantum dots into perovskite. Researchers in The Edward S. Rogers Sr. Department of Electrical & Computer Engineering invented […]

Hiroshima University researchers have announced fabrication of a silicon quantum dot based hybrid inorganic/organic light-emitting diode (LED) that exhibits white-blue electroluminescence. The hybrid LED is expected to be a next-generation illumination device for producing flexible lighting and displays. The fabrication was done by Professor Ken-ichi Saitow at the Natural Science Center for Basic Research and […]

Scientists from Tohoku University in Japan have developed a new type of energy efficient flat light source based on carbon nanotubes. The new flat panel technology has a very low power consumption of around 0.1 Watt for every hour’s operation making them about a hundred times lower in energy consumption than an LED. With only […]

The Royal Swedish Academy of Sciences has decided to award the Nobel Physics Prize for 2014 for the invention of efficient blue light-emitting diodes which has enabled bright and energy-saving white light sources. The inventor recipients are Isamu Akasaki, of Meijo University in Nagoya and Nagoya University, Japan; Hiroshi Amano, of Nagoya University, Japan, and […]

Dr. Lai Yuk Ming, Dr. Loo Ka Hong and Prof. Michael Tse at the Hong Kong Polytechnic University Department of Electronic and Information Engineering have developed a high performance LED driver. The new driver powers LED lights with an innovative approach called “multi-level” PWM (Pulse-Width Modulation), which delivers remarkable improvements in terms of light quality […]
