摘要：

A　design　of　a　simple　LCD　display　system　used　in　portable　radio　frequency　identification　(RFID)　reader　is　presented　in　this　paper,　which　works　in　the　125　kHz　ISM　frequency.　Based　on　the　power　saving　consideration,　the　system　embeds　the　peripheral　driving　circuits　in　a　SOC　(System　on　a　Chip)　to　simplify　the　complex　driving　circuits　of　traditional　electrical　LCD　display　system.　Besides,　the　system　executes　the　decoding,　checking,　identifying,　real　time　calculation,　and　data　display　by　means　of　software　tool　developed　in　this　paper.　The　proposed　system　has　advantages　such　as　simple　structure,　low　cost,　and　low　power　consumption.
