Micro-LED　display　has　risen　to　prominence　in　research　and　industry,　distinguished　by　their　numerous　advantages.　Quantum　dots　(QDs)　film,　serving　as　color　conversion　layers　(CCLs)　for　Micro-LED,　are　considered　a　leading　candidate　for　the　next　generation　of　displays,　owing　to　their　low　power　consumption　and　broad　color　gamut.　Inkjet　printing　stands　out　as　a　feasible　approach　for　crafting　QDs　CCLs.　The　essence　of　the　process　hinges　on　attaining　a　printed　QDs　film　that　boasts　both　uniformity　and　high-precision　QDs　array.　However,　the　unstable　printing　of　QDs　ink　significantly　impacts　the　surface　morphology　of　QDs　arrays　and　the　display　performance　of　Micro-LEDs.　Therefore,　elucidating　the　mechanism　behind　the　unstable　printing　of　QDs　in　inkjet　printing　and　fabricating　QDs　is　of　paramount　importance.　In　this　study,　through　the　simulation　of　unstable　printing　with　conventional　QDs　ink,　we　identified　nozzle　blockage　and　the　rapid　evaporation　of　low-boiling-point　ink　as　the　primary　causes　of　unstable　printing.　This　leads　to　aggregation　and　deposition　of　QDs,　obstructing　the　nozzle　and　altering　the　fluid　path.　A　novel　binary　organic　composite　ink　was　employed　to　print　the　QDs　array　on　the　substrate　with　ultra-stability,　achieving　a　high　yield　and　greatly　reduced　coffee-ring　effect　Micro-LED　full-color　display.
