P‐137: Enhancement of Light Extraction Efficiency and Roll‐Off Characteristics of Thermally Activated Delayed Fluorescence Organic Light‐Emitting Diodes by Inserting Nanoscale Pixel‐Defining Layer

This study demonstrated organic light‐emitting diodes (OLEDs) with high optical efficiency and suppressed roll‐off characteristics by harvesting the synergistic effect of hybridizing the mixed‐host material combination and the nanopatterning structural technique. This pioneering demonstration of nanoarray configuration in a third‐generation emitting organic molecule‐based device is expected to provide new strategies for the design of high‐performance OLEDs.
