Although this is not the first time we've seen an efficiency increase in blue OLEDs, it's worth noting that their proposed cap of productivity up to this point was a lowly five percent. It's exciting to learn, therefore, about a breakthrough by professor John Kieffer and graduate student Changgua Zhen from the University of Michigan, which has resulted in them successfully increasing azure diode power efficiency by 100 percent. The duo, accompanied by some bright minds in Singapore, manipulated performance controllers by rearranging OLED molecules in a computer model, improving material characteristics. In simple terms though, we're still looking at a measly ten percent efficiency, so we'll see where they take it from here.
