A　method　of　zinc　oxide　(ZnO)　mixing　is　presented　in　order　to　improve　low　lightness　and　bad　uniformity　of　carbon　nanotubes　(CNTs)　filed　emission　display.　The　paste　was　synthesized　by　mixing　Multi-walled　CNTs,　ZnO　and　organic　vehicle,　and　the　ZnO-CNT　samples　are　fabricated　with　screen-printed　technology.　Compared　to　usual　CNT　film　with　same　printing　area,　the　turn-on　electric　field　of　ZnO-CNT　film　decreased　from　2.2V/μm　to　1.17V/μm,　and　emission　current　increased　from　185μA　to　510μA　under　2.2V/μm.　Moreover,　stability　and　uniformity　of　emission　current　is　enhanced.　By　characterizing　ZnO-CNT　film　via　SEM　and　laser　granularity　analyze,　it　is　evaluated　that　ZnO　filled　the　interspaces　of　CNTs　or　covered　topside　of　CNTs,　high　electric　conductivity　and　thermal　conductivity　of　the　film　are　achieved,　and　active　emitters　increased.　Hence　better　field　emission　characteristics　are　achieved.
