Resolution　is　a　critical　parameter　in　assessing　the　performance　of　a　display.　The　demand　for　higher　resolution　displays　extends　beyond　the　competitive　needs　of　consumer　electronics　manufacturers　to　the　urgent　requirements　of　fields　such　as　scientific　research，　industry，　and　medicine，　which　need　high-resolution　displays　to　present　more　precise　images.　In　addition，　virtual　and　augmented　reality　technologies　enable　ultra-high-resolution　displays　to　provide　richer　human-computer　interaction　experiences.　Ultra-high-resolution　display　technology　has　gradually　become　a　popular　research　direction.　This　article　introduces　the　technical　means　and　solutions　for　achieving　high-resolution　displays　in　various　new　display　technologies　based　on　light-emitting　diodes，　summarizes　the　applicable　conditions　and　advantages　and　disadvantages　of　each　solution，　and　points　out　the　main　challenges　facing　each　technology　at　this　stage.　Our　team　has　long　been　committed　to　the　electroluminescent　patterning　and　high-resolution　display　research　of　quantum　dot　light-emitting　diode　displays.　This　article　introduces　the　groundbreaking　research　results　from　our　team　has　achieved　recently.　©　2023　Chines　Academy　of　Sciences.　All　rights　reserved.
