Technology:
NGK Insulators confirmed that the gallium nitride wafer it developed with Hiroshi Amano of Nagoya University doubles the luminous efficiency of a green light emitting diode as compared with the existing green light emitting diode.
In the experiment of a green light emitting diode that uses the newly developed gallium nitride wafer, the internal quantum efficiency that shows luminous efficiency doubled to 60%. The company has already achieved luminous efficiency of 90% in blue light emitting diode. The company plans to quintuple the monthly production capacity of gallium nitride wafers to 1,000 pieces in 2013. Please click here to read detailed information.
