  • Title: Organic light-emitting diode-based good light
  • Abstract:

    Energy-saving is no longer the only crucial factor to pursue for general lighting. In addition to high power efficiency, a ‘good’ light should at least be environmentally-friendly, human-friendly, and high quality. By realizing the notorious effects of blue light on artworks, human eyes, and physiology, devising a good light that is free from the blue hazards has become a must and urgent. We will demonstrate in the presentation the feasibility of employing organic light-emitting diodes (OLEDs) to enable a plausibly artwork-, human-eyes-, and physiologically-friendly light source with very low color temperature (CT < 2,000K) and very high natural light spectrum resemblance index, (SRI > 90). Especially, the OLED-based light source can also be made nearly blue-emission free and with a spectrum closely matching that of the dusk-hue or candle light. A prototype luminaire based on the candle light-style OLED will also be revealed, proving the possibility in replacing the hydrocarbon-burning candles that invented 5,000 years ago. At the end, an OLED-based good light that is free of mercury, ultraviolet, infrared, flickering, glare, and blue emission will be compared against the current lighting measures, including an LED, a compact fluorescent lamp, an incandescent bulb, and a candle.

    Prof. Jou received his B.S. in 1980 from National Tsing-Hua University and PhD in 1986 from Macromolecular Science and Engineering Program, University of Michigan (USA). In 1986 he joined as a Postdoctoral Visiting Scientist at IBM-Almaden Research Center, San Jose, CA, USA, and then joined National Tsing-Hua University in 1988 as an Associate Professor.  In 1992, he received academic title Professor.

    Professor Jou's research interests include sunlight style organic light emitting diodes (OLEDs); candle light style OLEDs, high efficiency low color temperature OLEDs, ultra-deep blue OLEDs, very high color rendering index OLEDs, spectrum resemblance index to measure the quality of light, flexible OLEDs, long lifetime OLEDs, thin film stress analysis, polymers and expert system applications. He has made several breakthrough inventions, including Sunlight style color-temperature tunable OLED, Candle light style OLED, Chromaticity tunable between dusk-hue and candle-light OLED, and Solution pre-mixed method for OLEDs fabrication etc. He is the author of over 120 international peer reviewed journal papers, and has filed or  been granted over 65 patents including 20 US patents. He has delivered more than 35 talks as an invited or plenary speaker in international conferences over the past five years. In the past three years, he has also delivered 24 invited talks on OLEDs and 19 invited talks on Engineering Ethics in Taiwan. He was awarded “Excellence in Industry-Academic Cooperation" Taiwan (2013); International Inventor Prize (IIP) (2012); “Award of Excellence Commercialization” Taiwan (2012); 2012 ITRI (Industrial Technology Research Institute) Laurel lecturer; 2007-2011 Outstanding Academic Teaching Awards; 2009 and 2010 NTHU-Academic Summit Program: Boost Program Research Funding; “Prism award for Photonics Innovation” finalist 2009; “Outstanding Poster Paper Award” International Display Workshop (2007); “Boost Programme Research Funding” 2007; “Excellence Research Program Funding” (2006); National Science Council (NSC) Outstanding Research Award-1992; “NSC Grade-A Research Award” 1989-1991, 1995-1999; “Booster Programme Research Funding” (1991).
