Idemitsu Kosan shows new OLED materials and lighting panels

Idemitsu Kosan is showing some new OLED lighting prototypes using their own fluorescent and phosphorescent OLED materials. Phosphorescent OLEDs are more efficient than fluorescent ones. In the following photo, the panel on the left has a high-color temperature, and uses both fluorescent and phosphorescent materials (it is targeted mainly for the EU market). The other 3 panels use just fluorescent materials, and have a low color temperature.

Idemitsu has already commercialized their red phosphorescent, and almost commercialized the green one. They still do not know when they'll be able to release a blue color material, currently the lifetime is about 10% of what the clients need.



Here's the data sheet for the OLED materials, where you can see the lifetime and efficiency of each color:
