Mitsubishi Chemical and Pioneer have been jointly developing OLED lighting technologies for a long time, including printed OLED panels. The companies are currently producing OLED lighting panels in which the bottom layer is coated and the emissive layer and the top layers are deposited by evaporation in vacuum (VTE).
Now the two companies presented a prototype panel in which both the bottom layer and the emissive layer were coated (the top layer was still deposited using VTE). The companies say this new process will reduce the cost of the panel to 10% compared to current OLEDs due to improved material utilization. They also say taht the new panels will feature much longer lifetimes.
