The display colorimetric accuracy is a key factor to ensure printing quality. The main mission for display’s color management is to compute its display color to get accurate colorimetric characterization, namely to ascertain the converting relationship between the RGB color data and their corresponding CIE X Y Z values. The related color values of EIZO, Mac and common PC displays were measured in the experiment, fitted the parameter, and computed the displayed color with gain-offset-gamma(GOG)model.Two-Primary Crosstalk (TPC) model, Piecewise Partition (PP)model. The three models were analyzed and compared with the measurement values. The model performance was assessed using 729 color samples uniformly distributed on the RGB display gamut. Compare the measured values and computed values and then find the more precise way to determine the display’s colorimetric characterization.
