摘　　要：An improved two-stage model of colorimetric characterization for liquid crystal display （LCD） was proposed. The model included an S-shape nonlinear function with four coefficients for each channel to fit the Tone reproduction curve （TRC）, and a linear transfer matrix with black-level correction. To compare with the simple model （SM）, gain-offset-gain （GOG）, S-curve and three-one-dimensional look-up tables （3-1D LUTs） models, an identical LCD was characterized and the color differences were calculated and summarized using the set of 7 × 7 × 7 digital-to-analog converter （DAC） triplets as test data. The experimental results showed that the model was outperformed in comparison with the GOG and SM ones, and near to that of the S-curve model and 3-1D LUTs method.An improved two-stage model of colorimetric characterization for liquid crystal display （LCD） was proposed.
