    Abstract: 本論文探討如何改進顯示器的顯色精準度,尋求一有效的校正模
    但其程序較為複雜。;The purpose of this thesis is to explore for an effective calibration
    process to highly improve the performance of displays. In such a way, the
    calibrated displays can present high quality contents with high accuracy
    both in photometric and in chromatic evaluation. Firstly, we have executed
    photometric and chromatic measurements on the performance of displays.
    After analyzing the measured data, several photometric and chromatic
    models between the controlling gray levels and display outputs of
    luminance and chromaticity have been established for each one of the
    primary color channels. With these photometric and chromatic models, the
    high accuracy calibration on a display is approached both in the
    photometric and the chromatic performance. Currently, the calibration
    process for a display is based on the color mixing among three fixed color
    primaries. By a linear transformation, the color difference between the
    color mixing prediction and the realistic performance of a display is
    expected to be diminished. However, we found a display does not work in
    such a simple way. That is why every display has its own exclusive
    performance even for the same contents. Here, we propose two effective models for the color mixing in displays. One is the linear superposition
    mixing model, and the other is the spectral principal component mixing
    model. Both of these two ways can effectively solve the unneglectable
    color shiting problems in displays. Accordingly, the leaking primary color
    can be well evaluated such as to have accurate calibration. The spectral
    principal component mixing model provides with much better accuracy
    than the linear superposition mixing model, while with more complicated
