Long live the efficient, pure-blue OLED: Novel approach shows promise for overcoming the bottleneck of blue emission in displays using organic light-emitting diodes – Science Daily

Using a new combination of emitter molecules, researchers in Japan have demonstrated the promise of a novel approach to finally overcome a major challenge facing displays using organic light-emitting diodes: a blue light source matching the excellent performance of the 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,…
