In　this　paper,　a　kind　of　driving　system　that　realized　displaying　video　on　FED　panel　is　developed,　and　principles　of　low　work　function　printable　field　emission　display　system　including　the　transform　and　processing　of　digital　video　image　and　the　transmission　of　the　video　data,　interface　circuit,　gray-shade　column　driving,　row　driving　technology,　and　FPGA　control　technology　are　described.　In　order　to　improve　display　effect　of　the　printable　FED,　the　brightness　for　non-uniformity　correction　method,　gamma　correction　method　and　automatic　power　control　method　are　proposed　by　theoretical　analyzing　and　practical　certificating.　The　quality　of　image　processing　used　in　driving　circuit,　image　brightness　uniformity　and　gray-scale　reproduction　is　improved,　besides,　the　sample　power　consume　is　reduced.　At　present,　the　technology　has　been　used　in　the　25　inch　colorful　low-work-function　printable　FED　sample　in　our　lab,　which　can　display　colorful　video　and　obtains　the　brightness　about　400　cd/m2,　contrast　ratio　1000:1,　256　circuit　gray　scales.　So　far,　the　driving　system　has　been　applied　to　the　640×480　FED　panel　and　reached　good　result.
