Organic light-emitting diodes, or OLEDs have always had three different colors. There are red and green diodes, which currently have a very high efficiency, and then their blue friend, which is about as wasteful as they come.
Thankfully, some brainiacs at the University of Florida have been working nonstop to fix this problem, and they’ve recently re-set the record for efficiency with the diodes. Currently, they’re rocking blue OLED efficiency of 50 lumens per watt, which is halfway to their set goal of 100 lumens per watt.
Franky So, the head of the team has stated that the Gators have “achieved a new record in efficiency of blue organic light-emitting diodes, and because blue is essential to white light, the advance helps overcome a hurdle to lighting that is much more efficient than compact fluorescents.”
