Mitsubishi Chemical and Pioneer announced that they developed a bluelight-less OLED lighting panel. The OLE-P0909-C3S module which contains this panel is actually already shipping, and it is produced using the wet-coating process developed by the two Japanese companies.
The new panel emits a minimal portion of blue light - less than 1% of the amount emitted by Mitsubishi and Pioneer's regular 3000K OLED panel. The panel is a candle-color type - with a 1900K color temperature. The module size is 92.4x92.4 mm (active area 76x76 mm) and is 4.3 mm thick. The maximum luminance is 3,000 cd/m2.
Blue light has the highest energy among visible light, and it is widely acknowledged to bear harmful effects like discomfort to the eye and damage to the retina, as well as serve as a contributing factor to diseases such as cancer, diabetes, heart disease, obesity and insomnia. Mitsubishi says that the new panels are suitable for storage lighting of light-sensitive items such as cultural heritage and paintings, as well for illumination of bedrooms and medical practices.
In 2014 we reported that Taiwan's WiseChip is entering the OLED lighting market with plans to produce candle-light emitting OLEDs using technology developed at Taiwan's National Tsing-Hua University.
Mitsubishi and Pioneer started to produce OLED panels back in 2011 - and these panels are distributed by Verbatim in Europe and MPOL in Japan. In early 2014, Pioneer and Mitsubishi Chemical announced that they began to mass produce OLED lighting modules made with a "wet coating system".
