OLED is regarded as the next generation of lighting source technology. Tsinghua University's Department of Materials Professor Zhou Zhuohui's laboratory research team published the world's first "candle-light" OLED light source that does not need to burn hydrocarbons, and combined with ITRI, upstream materials and equipment factory, dedicated to Promote the launch of the proposed candlelight products.
Following Samsung, Panel Shuanghu Group and AUO are also actively developing the application of active AMOLED on the display panel. In addition, some manufacturers have invested in OLED lighting research and development, and they have to join the well-known lighting brands such as Philips and Osram to grab the lighting market.
Zhou Zhuohui said that he has mastered 10 key technologies and applied for and obtained patents. In addition, the laboratory has accumulated more than 40 OLED related patents, and foreign patent agents and well-known domestic manufacturers have actively contacted the purchase of patents.
Compared with the mature LED technology on the market, Zhou Zhuohui said that although the former is more energy-efficient, it is a point source, the spot is concentrated and glare, and the application is not suitable for indoor lighting; OLED is flat light and does not generate high heat. 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.
He said that instead of choosing white OLEDs, he will step out of the OLED niche market and find two killer applications, including superb color rendering lighting and ultra-low color temperature physiological friendly lighting. He said that the candle-light OLED light source is the first man-made candle light source that uses electricity and does not need to burn hydrocarbon. It has been recognized and published by internationally renowned journals.
Humans have used candles for 5,000 years. In addition to lighting, candlelight is the light source that affects the body's secretion of melatonin. It is also the most friendly source of human physiology, but candles are inconvenient. OLED's pseudo-candle light will not be hot, smoke-free, or fire-free. It is more convenient and energy-efficient to use than a candle, and creates a romantic atmosphere. If it can be mass-produced in the future, it will replace the candle.
ITRI said that the development of mass production machines for OLED-related vapor deposition equipment is expected to enter the testing phase before the end of 2013.
