Abstract The evolution of display technologies is rapidly transitioning from traditional screens to advanced augmented reality (AR)/virtual (VR) and wearable devices, where quantum dots (QDs) serve as crucial pure‐color emitters. While solution processing efficiently forms QD solids, challenges emerge in subsequent stages, such layer deposition, etching, solvent immersion. These issues become especially pronounced when developing diverse form factors, necessitating innovative patterning methods that are both reversible sustainable. Herein, a novel approach utilizing lipoic acid (LA) ligand presented, featuring carboxylic group for surface attachment disulfide ring structure. Upon i‐line UV exposure, the LA initiates ring‐opening polymerization (ROP), crosslinking QDs enhances their resistance. This method enables precise full‐color patterns with feature sizes small 3 µm pixel densities exceeding 3788 ppi. Additionally, it supports fabrication stretchable composites using LA‐derived monomers. ROP process allows flexibility, self‐healing, recovery, promoting sustainability expanding applications ultra‐fine on‐silicon displays.
