P‐16.1: Fully Inkjet‐Printed Organic Light‐Emitting Diodes Based on a Thermally Activated Delayed Fluorescent Emitter

Using a fully solution‐processed cross‐linking method, we demonstrate a technique for fabricating multilayer OLEDs based on Thermally Activated Delayed Fluorescence (TADF). Our approach addresses the challenge of interfacial miscibility frequently encountered during fabrication and remains compatible with industrial printing and coating technologies. Multilayer TADF‐based OLEDs utilizing fully inkjet‐printed organic layers are successfully manufactured. The fully printed devices exhibit a maximum luminance of 2830 cd/m², a maximum current efficiency of 6.52 cd/A, and a maximum external quantum efficiency (EQE) of 1.98%.
