Organic light emitting diodes (OLED) are a next step in the evolution of solid state lighting technology, complementing inorganic LEDs. This week, Germany’s Federal Ministry of Education and Research awarded an important research grant to Applied Materials, Merck KGaA and the Technical University of Braunschweig (TU-BS).
As countries look for ways to reduce their carbon footprints, lighting, which uses nearly 20% of the world’s energy, has become a key target — and increasingly solid state lighting (both LED and OLED-based) is being explored as an energy-efficient answer.
We’ve all heard about LEDs, but what about OLEDs? Both generate light using semiconductor technology, use less energy and are typically longer lasting than the incandescent or gas filled bulbs they are slated to replace: but that is where the resemblance stops.
