maybe this will save the world?

In short, that’s far more efficient than current-generation OLEDs and reduces the ecological footprint of OLED manufacturing.
Additionally, the first of its kind complex-based warm-white light-emitting device delivered a color rendering index (CRI) of 78. Conventional OLEDs typically average around 90 and decrease over usage time.
Although a fascinating and an incredible starting point, David Suddaby, who has in his own words indirectly worked on "emitters of all kinds," explains that most viewing panels and even lighting equipment leveraged by professionals in the movie-making industry "don't use anything with CRI's rated under 95."
Adds Suddaby, "A trained eye can easily see the difference without even using a color metering device that measures CRI. A 100 CRI is the gold standard which all is judged. That would either be the SUN (for cooler CRIs') or a PURE blackbody radiating at 3200K for warmer toned CRI's."
Still, the school's findings do mark an impressive junction in the evolution of OLED fabrication, if the CRI contingent can be modified even further.
Beyond potentially decreasing the average price for an OLED panel, the newly devised MnBz fabrication process could also ensure that such devices are energy-efficient. This is due largely to the high brightness specs of these MnBz-based emitters, as it could allow for more eco-friendly lighting systems and consumer electronics long-term.
