Abstract
Different source arrangements can significantly affect the material distribution within emitting layers of OLEDs. By optimizing the source arrangement, increasing the concentration of the assisted phosphor, and decreasing the concentration of the multi‐resonance fluorescent dopant at the interface, the efficiency of phosphor‐assisted fluorescence device can be enhanced by 14%.
