Creation of Five Values
An environmentally sound light that unites man and nature in a harmonious whole
The high energy efficiency of OLED lighting results in energy savings that in turn have a major impact on reducing CO2 emissions. Moreover, it contains no hazardous substances such as mercury, and therefore presents fewer problems for recycling. From an environmental perspective too OLED is a clean form of lighting suitable for the next generation.
Highly efficient light emission produces energy savings
OLED lighting is currently in the early stages of development but has the potential for highly efficient light emission, and is already almost as efficient as fluorescent light.
Furthermore, since it emits light from a surface, its practical application as an actual illumination device results in little waste, offering future potential energy savings of around 30% compared with fluorescent lamp (according to our calculations).
Assuming that 50% of fluorescent lamps and 40% of incandescent light bulbs are replaced with OLED lighting devices by 2030, it is possible to reduce overall power consumption for illumination by around 20% compared with the case where no replacement at all occurs (according to our calculations). With energy conservation and the reduction of CO2 emissions posing an urgent challenge on a global scale, high expectations are being placed on the practical application of OLED lighting.

Clean illumination that does not use hazardous substances
In Japan at least 85% of fluorescent lamps are dumped in landfills rather than recycled. Fluorescent lamps contain mercury, which has been designated as a hazardous substance by the RoHS Directive (EU directive to restrict the use of certain substances). However, because no substitute for mercury has yet been developed fluorescent lamps have received a special exemption (*3)and continue to be used.
OLED lighting does not use substances that pose a hazard at the time of disposal. It is a clean form of illumination ideally suited to lighting up the earth for the next generation.
