OLED lighting panel boasts 131lm/W efficiency
The company had previously produced a panel featuring 103lm/W but since then the company has incorporated three new technologies in the panel design that has enabled the record efficiency to be attained.
A phosphorescent blue material has been used to improve the internal quantum efficiency. The company has also implemented a light extraction technology and developed an organic layer construction technique using optical simulation.
The previous record for OLED panel efficiency was held by Panasonic that claimed a white OLED lighting panel that featured 114lm/W for a light-emitting area of 1cm2.
The company describes that its Irodori demonstration model will show the world's first flexible-type OLED lighting panels with color tunable function that are designed in layers like peacock feathers. The demonstration model will rotate slowly to show its expressive nuance through the changing colors. As the panels adopt different layer construction from that of displays, the color-tunable panels emit light evenly over the complete surface.
