This paper proposes a color characterization model for predicting colorimetric information of all types of displays with high accuracy. Light leakage from black pixels causes errors in colorimetric information. By considering it, the proposed color characterization model accurately estimates colorimetric information of the red, green, and blue subpixels independently. In order to verify the universality of the proposed model, we apply it to all types of displays, including the organic light-emitting diode display. In addition, we show that the proposed model is more accurate than two of the most commonly used models, namely, the piecewise linear assuming chromaticity constancy model and the piecewise linear assuming variation in chromaticity model.
