Organic light-emitting diodes (OLEDs) will become the next-generation lighting source technology. Professor Zhou Zhuohui's research team released the world's first organic light-emitting diode (O LED) illumination source closest to natural light yesterday (15).
AUO and Qijing Optoelectronics also invested in OLED lighting research and development, and shares with the foreign giants such as General Electric (GE), Philips, and Osram.
Zhou Zhuohui led the research team yesterday to publish the world's first OLED illumination source that is closest to natural light. It can be used as a clear sky and sunset light source. It can be concentrated on a single light sheet. With different voltages, it can emit various kinds of sunlight including clear sky and warm afterglow. The light source is close to natural sunlight and is currently the best indoor lighting technology, which is better than the current hot LED.
In addition to being published in international journals, the research results have been applied for patent new invention patents in Taiwan, the United States, Europe, Japan, and Korea. The Qingda team explained that the only OLED lamp that has been produced in the world on the market is the white light product launched by Lumiotec, which is invested by companies such as Mitsubishi Heavy Industries of Japan. However, the lighting has only a single color temperature and can only be displayed indoors. Day "feeling.
Zhou Zhuohui said that international companies such as OSRAM, Philips, and General Electric (GE) are also gaining momentum in the OLED industry. Taiwan's AUO and Qijing Optoelectronics are also investing in OLED lighting research and development. With the widespread application of OLED lighting technology in indoor lighting, it is expected to generate an output value of 200 billion yuan in 2018, accounting for 25% of the overall urban lighting market and reducing nearly 7 million tons (equivalent to 2.3% globally) within 15 to 20 years. Greenhouse gases.
Compared with the mature LED technology on the market, Zhou Zhuohui said that although the former is still more energy-efficient, it is a point source, the spot is concentrated and glare, and the application is not suitable for indoor lighting; while OLED is flat light, it will not produce High heat and soft.
OLED is not only applied to the display, but also can be used as an illumination source, OLED cold light characteristics, and can solve the heat dissipation problem of LED illumination. Zhou Zhuohui pointed out that OLED will rewrite the history of human lighting, which will be of great help to winter or long-term areas without sunlight.
According to the latest research data from DisplaySearch's second quarter OLED shipment report, the market for OLED displays is climbing. The overall revenue in 2008 was 600 million US dollars. In 2016, it will grow sharply to 7.1 billion US dollars, with a compound annual growth rate of 36%. Global OLED display revenues were $143 million in the first quarter of 2009, down 8% from the previous quarter.
In January 2009, Samsung’s mobile phone panel division merged with Samsung’s SDI OLED division, and SMD (Samsung Mobile Panels) was established. SMD is the market leader with 37% market share, surpassing second place. Sic Bo Technology. 
Reports from local media in Taiwan, the laboratory research team led by Zhou Zhuohui (middle), professor of materials at Tsinghua University, Taiwan, developed the first solar-colored O LED illumination source, and applied for patents in Taiwan, the United States, Europe, Japan and Korea. in.
