On July 15th, the laboratory research team led by Zhou Zhuo, a professor of materials at Tsinghua University in Taiwan, developed the first "sunlight color" O LED illumination source. Professor Zhou Zhuo? published the world's first and most OLED lighting close to natural light, can be like a clear sky, sunset light source, can be concentrated on a light sheet, using different voltages, respectively, including a variety of daylight, such as clear sky, warm afterglow, light source close to natural sunshine, is currently the best indoor lighting technology , better than the red LED.
The research results have been published in the International Journal of Applied Physics (APL) and have been applied for patent new invention patents in Taiwan, the United States, Europe, Japan and Korea. Zhou Zhuo? The team said that at present, only the white light O led products launched by Lumiotec, which is invested by companies such as Mitsubishi Heavy Industries of Japan, are mass-produced, but the lighting has only a single color temperature and can only present a "daytime cloudy" feeling indoors.
Professor Zhou Zhuo said that because OLED is a flat-emitting light and meets environmental protection requirements, it can be made on plastic sheets and posted like a wallpaper. Therefore, it has been insisting on the research direction of OLED for many years. When students studied the lighting mechanism a year ago, they found that there was a material instability. Professor Zhou Zhuo? reverse thinking and decided to use this feature to make the light change at will. He and graduate students experimented with a variety of fluorescent materials to find materials that can emit blue, green, and red primary colors at the same time. The voltage of 3~9V is matched with a square battery, which can emit different light colors from sunrise to sunset.
At present, Japan has introduced a 15x15cm white OLED sample with a single color temperature, which is priced at about 5,000 yen.
