This is not the first time we have seen scientists publish a more efficient blue OLED , but the results are quite noteworthy because it breaks the old thinking that the upper limit of the luminous efficiency of fluorescent OLEDs is only 5%. Double it up and come to the new 10% new realm.
In general, the lifetime of a fluorescent OLED is longer than that of a phosphorescent OLED, but its luminous efficiency is low and poor.
Fluorescent OLED
The study, led by Professor John Kieffer of the University of Michigan, led by graduate student Changgua Zhen and the Singapore team, aims to improve the luminous efficiency of fluorescent OLEDs. The research team first classified and built the OLED composition into a computer model, and then systematically used the computer to simulate the various combinations, and finally found this result. Although the luminous efficiency after doubling is still only a small poor 10%, who knows whether this is the "starting point" or the "end point"? Let us look forward to the follow-up development. Scientists' new discoveries have doubled the luminous efficiency of blue OLEDs.
