Sumitomo will exhibit a PLED installation called OLED Cosmos, designed by Motoko Ishii. This installation will use new dual-color OLED panels. These panels (produced using printing technologies) use two distinct colors.
Sumitomo says that they will start marketing those panels later in April 2014. They say the panels will be low-cost (due to the advanced printing process) and will be available in a wide range of lighting colors. The company previously achieved an efficiency of 42 lm/W, but I don't know what will be the efficiency of their commercial panels.
