In　order　to　achieve　electrowetting　real-time　display,　a　display　driving　system,　consisting　of　a　DVI　video　codec　system　and　FPGA　timing　control　system,　is　designed.　DVI　video　codec　system　is　responsible　for　obtaining　signal　sources　and　for　image　coding　and　decoding.　FPGA　is　responsible　for　buffering　and　processing　of　video　data　and　for　controlling　electrowetting　driving　waveforms.　This　paper　also　proposes　an　improved　multi-grayscales　dynamic　symmetrical　driving　waveform,　which　improves　the　ink-splitting　phenomenon　and　suppresses　the　charge-trapping　phenomenon　while　increasing　the　gray　level.　The　results　show　that　the　driving　system　successfully　improves　the　problems　of　oil-splitting　and　charge-trapping,　and　drives　the　1024×768　resolution　electrowetting　display　to　play　video　in　real　time　following　the　computer.　The　frame　rate　of　the　video　reaches　60　frames/second,　and　the　highest　gray　level　of　the　pixel　reaches　15.　These　properties　meet　the　requirements　for　dynamic　display　of　the　electrowetting　paper.　©　2019,　Editorial　Office　of　Opto-Electronic　Engineering.　All　right　reserved.
