Abstract
We describe a display calibration model that is suitable for liquid-crystal displays (LCDs). In conventional display calibration models, the spectral radiance of light emitted from the display is estimated using the data measured for each primary color based on the assumption of RGB channel additivity, however, this assumption does not hold for LCDs. With only a few measurements of the spectral radiance or tristimulus values, the proposed model accurately approximates the colorimetric characteristics of the display. To evaluate the effectiveness of the model, we used it to measure the RGB primary colors, the CMYK secondary and the tertiary colors. The colors were analyzed based on principal component analysis to identify the effect of channel interaction. The proposed model was found to be more effective than conventional models for the colorimetry of LCDs.
