Credit: Professor Ifor SamuelNew interdisciplinary research study from the University of St Andrews has the possible to boost the performance of tvs, computer system screens, and lighting systems.Researchers at the Organic Semiconductor Centre in the School of Physics and Astronomy, and the School of Chemistry have actually proposed a new approach to designing effective light-emitting materials in a paper recently published in Nature.Light-emitting materials are used in natural light-emitting diodes (OLEDs) that are now discovered in the bulk of mobile phone display screens and smartwatches, and some tvs and vehicle lighting.Overcoming Efficiency ChallengesThe latest generation of emitter products under development produce OLEDs that have high performance at low brightness, but suffer decreased efficiency as the brightness is increased to the levels required for lighting and outside applications. Guidelines developed by the group of researchers, led by Professor Ifor Samuel and Professor Eli Zysman-Colman, will help OLED scientists develop products that maintain high performance at high brightness, allowing the most current products to be used for applications in display screens, lighting, and medicine.Commenting on the research study, Professor Zysman-Colman explained that the findings “offer clearer insight into the link between the homes of the emitter material and the efficiency of the OLED.
