As　carriers　of　visual　information,　displays　play　an　indispensable　role　in　our　daily　life.　In　recent　years,　high-resolution　(HR)　self-emissive　displays　have　been　rapidly　developed　because　of　the　expanding　market　demand　for　microdisplay　products;　consequently,　research　on　the　improvement　of　display　resolution,　material　and　device　structure　optimization,　the　design　and　development　of　drive　circuits,　and　various　applications　of　HR　display　technology　has　significantly　increased.　However,　there　is　no　comprehensive　review　of　HR　light-emitting　devices.　This　review　focuses　on　HR　light-emitting　technologies.　The　main　contents　of　the　review　are　as　follows:　(1)　methods　for　fabricating　HR　light-emitting　devices;　(2)　processes　for　fabricating　self-emissive　displays　and　other　potential　fine　patterning　techniques　for　the　same　purpose;　(3)　the　advantages　and　limitations　of　these　processes;　(4)　the　challenges　associated　with　HR　displays.　This　review　can　serve　as　a　valuable　reference　for　the　development　of　the　microdisplay　industry　and　for　studies　on　microdisplays.
