Organic light-emitting diode (OLED) will become the next generation of lighting source technology. Tsinghua University's material research professor Zhou Zhuohui's laboratory research team announced on the 15th the world's first organic light-emitting diode (OLED) illumination closest to natural light.
Zhou Zhuohui led the research team and published the world's first OLED lighting closest to natural light. It can be used as a clear sky and sunset light source. It can be concentrated on one light sheet. With different voltages, it emits various kinds of sunlight including clear sky and warm afterglow, and the light source is close. Natural sunshine is currently the best indoor lighting technology, better than the red 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 on the market that has been produced in the world 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 rendered indoors during the day. Day 'feeling.
Zhou Zhuohui said that international companies such as Osram, Philips, and singular are also preparing for 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 explained 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 urban lighting; while OLED is flat light, it will not Produces high heat and is 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 will reach 600 million US dollars. In 2016, it will grow 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.
