Color management system (CMS) using ICC profile or sRGB space is becoming popular since the number of color devices are increasing. In such CMS, accurate colorimetric characterization of display device has a critical role for achieving device independent color reproduction. In case of CRT, colorimetric characterization based on GOG model is accurate enough for this purpose. However, there is no effective counterpart in Liquid Crystal Displays (LCD) since the characterization of LCD has many difficulties such as channel interaction, non-constancy of channel chromaticity. In this paper, a new method of display characterization is proposed which is applicable to the assessment of color reproduction of LCD. The proposed method characterizes electro-optical transfer function considering both channel interaction and non-constancy of channel chromaticity. In the experiment, comparisons with five conventional characterization methods proved that the proposed method is very significant to the colorimetry of LCD.
