Accurate colorimetric characterization is an important step in establishing the color management system (CMS) for liquid crystal displays (LCDs) to achieve device‐independent color reproduction. The gain‐offset‐gamma (GOG) model that is accurate enough in describing the tone reproduction curves (TRCs) for CRT displays has been found inadequate for characterizing LCDs due to mainly channel interaction and non‐constancy of channel chromaticity. In this paper, a modified GOG model that takes channel interaction and backlight leakage into account is proposed to accurately characterize the TRCs of LCDs. Experimental results indicate that the proposed model outperforms the conventional GOG model in terms of the CIEDE2000 color difference between the XYZ values of the measured color sample and the estimated XYZ values.
