Direct Writing High‐Resolution Quantum Dot Micro‐Patterns: Toward High‐Performance Electroluminescence Behavior

ABSTRACT The fabrication of quantum dots (QDs) micro‐patterns, especially those with both µm‐scale high‐resolution and mm‐/cm‐ scale large area uniformity, remains a bottleneck limiting the application of quantum dot light‐emitting diodes (QLEDs). Current strategies have suffered from either low resolution or complicated micro‐template assisted fabrications deteriorating the device performance. Here, we developed a new conceptual high‐resolution QDs micro‐pattern with a linewidth of merely 2 µm
