More Information
Summary:A color temperature adjusting method of a display device includes follow steps: generating a color temperature curve according a color temperature range, the Planckian locus of CIE 1931 color space and CIE daylight locus; calculating a target color temperature on the color temperature curve corresponding to a target color coordinates; generating a new brightness ratio of red, green and blue respectively according to the target color coordinates and the tristimulus values of the brightness red, the brightness green and the brightness blue of the display device; generating a coefficient of red, green and blue respectively according to the new brightness ratios of red, green and blue and the tristimulus values of red, green and blue; and adjusting color temperature of the display device according to the coefficients of red, green and blue.
