University of Michigan engineering researchers have designed an exceptionally efficient fluorescent blue OLED.
“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.
This was accomplished by redesigning a material being utilized by U-M collaborators in Singapore using computer simulations.
“With the material, they had some positive results,” Kieffer said. “We took those molecules and started to reconfigure them in a computer model, adding different functional groups in a systematic way. We identified the mechanisms that control the performance of OLEDs, and by applying the fundamental understanding so obtained we improved the materials characteristics. Our research demonstrated the importance of simulation-based predictive design.”
The paper is called: “Achieving Highly Efficient Fluorescent Blue Organic Light-Emitting Diodes Through Optimizing Molecular Structures and Device Configuration”
