New multidisciplinary research could lead to more efficient televisions, computer screens and lighting.

New multidisciplinary research from the University of St Andrews could lead to more efficient televisions, computer screens and lighting.

The latest generation of emitter materials under development produce OLEDs that have high efficiency at low brightness, but suffer reduced efficiency as the brightness is increased to the levels required for lighting and outdoor applications. This problem is known as 'efficiency roll-off'. Commenting on the research, Professor Zysman-Colman explained that the findings"provide clearer insight into the link between the properties of the emitter material and the performance of the OLED."
