Record 36.7% EQE Achieved in Deep-Blue Phosphor-Sensitized Fluorescent OLED

Researchers from Inha University and Pusan National University have developed a new type of display technology. The team created a deep-blue phosphor-sensitized fluorescent OLED device. This innovation addresses one of the most sensitive components in OLED technology. The device achieves an external quantum efficiency of 36.7 percent. This figure represents a record-breaking performance level for blue OLEDs.

The manufacturing process for this device relies on solution processing. This method allows the OLED materials to be applied in a soluble form. The team utilized a platinum complex combined with a templating layer to achieve these results. The high efficiency is critical because blue emitters typically degrade faster than other colors. This laboratory result demonstrates significant progress in material stability and performance.
