Japan developed a new type of lighting device using carbon nanotube FED Technology

Tohoku University Japan Graduate School of Environmental Sciences and the same and holding company (Dowa Holdings) announced on January 9, 2013, the two sides jointly developed the use of carbon nanotubes (CNT) cold cathode field emission type light emitting device. FED (field emission display, field emission display) technology, which was used primarily for display purposes, was switched to lighting. Tohoku University Japan and the same will be in the lighting show "LIGHTING JAPAN 2013" (January 2013 ~ 18 ~ 16, Tokyo Ming International Convention and Exhibition Center) on the device related research results. FED technology is the technology of emitting electrons from the cathode in a vacuum environment, so that the electrons impact the fluorescent material. The principle is similar to cathode ray tube (CRT) technology. In the early 2000s, in order to achieve the use of FED technology ultra-thin display for the purpose of the research is very active. In order to carbon nanotubes as cathode display, although Japan's new energy and Industrial Technology Development Organization (NEDO) also in promoting development, but affected by the popularity of LCD panel, has been unable to launch related products. The Northeastern University and the European Union and the European Union in the use of carbon nanotubes to form a cold cathode technology breakthrough. According to reports, the technology used to manufacture long life, low power consumption, high brightness lighting devices have been developed.
