The invention of electricity, diode scientists won the Millennium Technology Prize

In September 8th, the blue light-emitting diode inventor, 52 year old Japanese scientist Nakamura Shuji in Finland, the capital of Helsinki won the world's millennium technology award". He won a prize of 1 million euros and a prize called "peak".

In 1993, as a technician in Japan Nichia Corporation Nakamura Shuji developed a blue high brightness led to more abundant computer, mobile phone, ultra-thin TV screen color components, service life is greatly prolonged, and the power consumption is reduced by 90%.

The earliest development of light-emitting diodes, can only issue a red light, mainly used as an indicator of electronic equipment. Later, the yellow light, green light emitting diodes have come out, only the three primary blue. The appearance of GaN Blue LED fundamentally solves this problem and becomes the indispensable key component of full-color display.

GaN based blue light emitting diode has the advantages of small volume, cold light source, long life, high luminous efficiency, can be used in large screen display, traffic lights, multimedia imaging, LCD backlight, optical fiber communication, satellite communication and optical communication and other fields of marine.

With this achievement, Nakamura Shuji as early as June 15th this year, the Finland Technology Award Foundation was identified as the Millennium Technology Award winner. Foundation believes that the invention of Nakamura Shuji opened a new era in the field of research and development of light-emitting diodes. His invention makes it possible to produce blue light emitting diodes with large scale industrialization and has a positive effect on improving and improving the quality of life of human beings.

The millennium technology prize is one of the world's most awarded prizes in science and Technology awarded every two years to identify individuals or research groups who have made significant achievements in scientific research or invention. Finland science and Technology Award Foundation Award criteria is that the award-winning scientific research and invention should be able to directly improve and improve the quality of human life, a positive role in the sustainable development of the economy. This year is the second award of the Finland Technology Award foundation". The first millennium technology prize was awarded to the World Wide Web inventor, Professor Tim Bernas Lee, British scientist in 2004.
