InP　quantum　dots　(QDs)　are　considered　to　be　one　of　the　most　promising　materials　for　application　in　light-emitting　devices　due　to　the　advantages　of　heavy-metal-free　characteristic　and　widely　tunable　spectrum　covering　most　of　the　visible　and　near-infrared　regions.　However,　the　performance　of　InP　quantum　dot　light-emitting　diodes　(QLEDs)　lags　far　behind　their　Cd-containing　counterparts,　especially　as　the　InP　pixelated　device　is　still　in　its　infancy.　In　this　study,　multi-component　functional　QD　inks　with　excellent　stability　and　printability　was　developed　for　inkjet　printing　InP　array　QLEDs.　High-quality　QD　films　can　be　obtained,　both　on　flat　and　bank-containing　substrates,　by　precisely　controlling　the　competition　between　capillary　and　Marangoni　flows　in　the　printed　droplets,　enabling　high　device　performance.　In　addition,　a　periodic　ZnO　microlens　arrays　was　prepared　by　nanoimprinting　technology　to　enhance　the　light　extraction　efficiency　of　inkjet-printed　InP　QLEDs,　leading　to　127.6%　improvement　in　external　quantum　efficiency　(EQE)　compared　to　the　control　device.　The　maximum　luminance,　EQE　and　current　efficiency　of　the　obtained　device　are　17,759　cd/m2,　8.1%　and　11.1　cd/A,　respectively.　These　results　may　facilitate　the　applications　of　high　performance　environment-friendly　QLEDs　by　inkjet　printing　technology.　©　2022　Elsevier　B.V.
