Quantum　dots　color　conversion(QDCC)is　considered　as　a　facial　and　versatile　way　to　achieve　full-color　organic　light　emitting　diode(OLED)and　micro-LED　display　due　to　the　wide　color　gamut　performance　and　easy　integration.However,the　aggregation　of　QDs　and　coffee-ring　effects　after　solvent　evaporation　lowers　the　light　conversion　efficiency　and　emission　uniformity　in　QDs　microarrays,raising　blue-light　leakage　or　optical　crosstalk.Here,we　report　the　fabrication　of　perovskite　quantum　dots(PQDs)microarrays　by　combining　the　inkjet　printing　and　in　situ　fabrication　of　PQDs　during　the　photopolymerization　of　precursor　ink.The　resulting　PQDs　microarrays　exhibit　three-dimensional(3D)morphology　with　hemisphere　shape　as　well　as　strong　photoluminescence,which　is　desirable　for　QDCC　applications.We　demonstrate　the　dominant　role　of　ultraviolet(UV)curable　precursors　and　surface　functionalized　substrate　in　controlling　the　shape　of　microarrays,where　significantly　increased　contact　angle(100°)and　large　height　to　diameter　ratio(0.42)can　be　achieved.We　further　demonstrate　the　potential　use　of　the　in　situ　direct　print　photopolymerization　method　for　fabricating　large-area　multicolor　patterned　pixel　microarrays　with　a　wide　color　gamut　and　high　resolution.The　fabrication　of　3D　PQDs　microarrays　opens　up　new　opportunities　in　a　variety　of　applications　including　photonics　integration,micro-LED,and　near-field　display.
