Konica Minolta developed the world's most efficient OLED lighting panel - at 131 lm/W. The panel's emitting area is 15 square centimeters. KM says that now OLEDs are actually more efficient than consumer LEDs, and this is a major step forward for OLED lighting. We do not know the lifetime or any other features of this panel.
KM's previous panel featured 103 lm/W and the company incorporated three new technologies in the new panel that enabled them to reach the record efficiency. First up is a new phosphorescent blue material that improved the internal quantum efficiency. In addition, KM also implemented a new light extraction technology and and a new "organic layer construction technique", based on optical simulation.
