In continuous operation, the researchers achieved an LT50 lifetime of almost 2000 hours at ten times the brightness of modern conventional displays. Within this time, the initial brightness has dropped to 50% of its value.
"Now we hope to further improve the concept and achieve even longer lifetimes. This would allow the concept to be used for industrial purposes," says Wetzelaer. With their newly developed single-layer concept, the scientists want to help identify and improve the processes responsible for reducing brightness.
The researchers published their results in the renowned journal "Nature Photonics".
