  • Method for compensating colors of a display device
    Patent number: 7425964
    Abstract: A color compensation method for a display device. A brightness eigenvalue and color gamut eigenvalue of the display device is determined. A plurality of signals of three major colors are applied into the display device to display a plurality of colors. The colors are measured to get a plurality of chromaticity eigenvalues. The brightness eigenvalue, the color gamut eigenvalue and the signals of the three major colors are applied into a formula to establish a color database. A target chromaticity eigenvalue and a data eigenvalue in the color database are applied into another formula to calculate a compensated signal eigenvalue to compensate color difference of the display device.
