Novel approach shows promise for overcoming the bottleneck of blue emission in displays using OLEDs – Phys.org

Using a new combination of emitter molecules, researchers in Japan have demonstrated the promise of a novel approach to overcome a major challenge facing displays using organic light-emitting diodes: a blue light source matching the excellent performance of red and green ones.
By splitting energy conversion and emission processes between two molecules, the researchers achieved devices that produce pure-blue emission with high efficiency, maintain brightness for relatively long times, and lack any…
