Blue Light Hazards and A Resolution Based on Candlelight OLED

Blue light appears in our daily life either via the use of smart phones, tablets and computers or general lighting. Over exposure to blue light or blue light enriched white light might cause retina damage. Extensive use of electric light at night might also cause other health issues, including sleep disorder, obesity, diabetes, cardiovascular dis-eases, and cancers of breast and prostate. We will demonstrate that blue light hazards from general lighting can be minimized by the introduction of candlelight OLED, which is presumably 10 times safer from retina protection perspective and 5 times better from melatonin generation perspective, as comparing with the cold white CFL, LED and OLED counterparts. It is hoped that Lighting Renaissance be triggered on basis of such a blue hazard free lighting measure.

About the Speaker

Prof. Jwohuei Jou (Joe) received his Master and Ph.D. degrees from the University of Michigan, Ann Arbor, Michigan, in 1985 and 1986, respectively. He worked as a Post-Doctoral Visiting Scientist at the IBM-Almaden Research Center, San Jose, California, from 1986 to 1988. After that, he has joined as an associate professor and then a full professor in the Department of Materials Science and Engineering, NTHU. He chaired the department from 2006 to 2009.

Prof. Jou has been working on OLED for more than 25 years. He invented the first sunlight-style OLED in 2009 and the first candlelight OLED in 2012. The latter invention has been given many awards lately, including the 2015 Lighting Design Award from the International Dark-Sky Association; the 2016 Outstanding Award of Excellent Paper from Taiwan Lighting Association; and the 2016 Golden Technology Award from Lite-On.
