Graphical　growth　was　realized　by　the　use　of　lithographic　technology　on　the　ITO　glass　substrate　covered　with　zinc　oxide　(ZnO)　thin　film.　Rectangular　and　circle　ZnO　arrays　which　had　integrated　structure　and　orderly　arrangement　were　prepared　on　substrate　by　hydrothermal　method.　The　ZnO　nanocone　arrays　were　secondarily　grown　based　on　graphical　once　growth.　The　maximum　length　was　10　μm.　Its　length　was　far　longer　than　the　length　which　was　grown　by　once　growth.　And　many　needle-like　micro-structures　of　nano　scale　were　found　on　the　tip　of　nanocone.　The　field　emission　performance　of　ZnO　nanocone　arrays　which　had　been　prepared　by　non-graphical,　graphical　once　growth　and　graphical　secondary　growth　were　analyzed.　A　12.7　cm　(5　inch)　size　FED　was　fabricated　by　using　the　ZnO　nanocone　cathode　array.　And　it　can　realize　full-screen　light　emitting.　The　experimental　results　showed　that　the　emission　current　density　of　ZnO　nanocone　by　graphical　secondary　growth　was　the　greatest.　Its　emission　current　density　was　0.6　mA/cm2　and　its　turn-on　field　was　2.5　V/μm.　The　graphical　growth　of　ZnO　nanocone　was　a　feasible　method　for　improving　field　emission　properties.　The　results　provided　an　effective　experimental　method　for　preparing　good　field　emission　performance　material.
