The accurate color characterization of displays is the basis of the color management. The characterization of the liquid crystal display (LCD) is difficult because of the variant primary chromaticity and primary crosstalk. The gain-offset-Gamma (GOG), Two-trimary crosstalk (TPC) and piecewise partition (PP) were employed to study on the experiments of color characterization of the same LCD. The characterization accuracy were evaluated with the CIEDE2000 color-difference formula. The experimental results show that the performance of the models were quite different. The mean color difference of the PP model reaches 1.2660 CIEDE2000, while the GOG model is 3.9849 CIEDE2000, and the TPC model is 5.8779 CIEDE2000. The GOG and TPC models can satisfy the general needs and the PP model can be used in the higher requisition color reproduction.
