Abstract：

Liquid　crystal　display　(LCD)　is　a　kind　of　display　devices　which　is　most　commonly　used　today.　As　the　color　space　of　LCD　is　device-dependent,　characterization　of　LCD　which　maps　the　color　space　of　LCD　to　CIE　standard　color　space　should　be　performed.　In　this　paper,　optoelectronic　property　and　color　display　principle　of　LCD　are　firstly　described;　then　some　existing　methods　of　characterization　are　analyzed;　finally,　advantages　and　disadvantages　of　3　characterization　methods　based　on　1-dimension　look-up　table　(1D-LUT)　are　compared　by　experiments.　And　it　is　shown　that　black-level　offset　and　optimization　play　important　roles　in　characterization　of　LCD　by　comparing　the　color　differences　of　different　methods.　In　the　end,　another　comparative　experiment,　in　which　color　reproduction　precision　in　local　gamut　of　models　trained　by　different　training　samples　is　compared,　is　implemented.　©　2013　IEEE.
