50 years ago now, Nick HolonyakJr — the United States Ge Corp ( General ElectricCany, GE ) , an ordinary researchers, research produced the world’s first red LED, and opened the LED Panel Light history. Now 50 years past, LED industry really like he prophesied before that ” LED will have many different colors of light, incandescent lamp, the future will be replaced by LED”. Now, in the low carbon energy trends, LED industry has become a country competing development products. As the fourth generation light source, LED has been widely used in a variety of display and illumination field, also lies in that in people’s life to bring a new round of lighting revolution.
On the occasion of the 50 anniversary of the LED method, we cannot forget that in 50 years of development of the road, the promotion of the LED step by step towards the revolutionary breakthrough of those great scientists and their great invention.
Red led lightings inventor —Nick HolonyakJr.
The invention in 1962 of LED Nick HolonyakJr., he was only the United States manufacturers Ge Corp ( General ElectricCany, GE, also known as the singular ), just an ordinary researchers. He created the first red LED, but he also believes that the future can emit light of the other wavelength, it means that LED will have many different colors of light, future incandescent light must be replaced by LED.
Yellow light inventor —-George Craford LED
George Craford the United States famous electrical engineer, in the field of led lightings contributions made by the most prominent. In 1972, Dr. Craford invented the yellow light and red and orange light LED. His graduate and doctoral students are enrolled in the United States of America Illinois University, specializing in physics, who obtained master’s degree 1963, doctorate in 1967. After graduated, he joined Monsanto chemical company, the company is the world’s first mass production of light emitting diode ( LED ) company, his team in 1972 developed nitrogen-doped GaAsP ( GaAsP ).
The father of the OLED – Deng Qingyun
In early 1979, Dr. Deng found OLED. That’s one evening in 1979, Dr. Deng is on the way to home. He suddenly thought of something forgotten in the laboratory, then returned to the laboratory. He found in the dark with a bright thing, that the original is an experimental organic battery in the light. Thus began the research on OLED.
