12‐2: A Universal High‐Resolution Patterning Technology for Quantum Dot Color Converters in Micro‐LED Displays

We report a photolithography‐based technology for patterning quantum dot color converters for micro‐LED displays. A patterning resolution of ~1 µm is achieved. The method can be applied to any color converter materials. Integration of perovskite quantum dots and CdSe/ZnS quantum dots is demonstrated to show the versatility of the technology.
