Researchers from the University of Michigan developed an efficient fluorescent blue OLED. Professor John Kieffer and grad­u­ate stu­dent Changgua Zhen dou­bled the exter­nal quan­tum effi­ciency of blue OLEDs from 5% to 10%.. The new material is a computer-simulations assisted redesign of a current material used by the University collaborators in Singapore via the University of Michigan.

“Our results clearly indicate that fluorescent material have a bright future for highly efficient and stable OLEDs for flat-panel display and lighting applications,” Kieffer said in a release issued by the University. Their findings were published in the journal, “Advanced Functional Materials.
