A multi-screen color correction method and an electronic device are provided. The multi-screen color correction method is adapted with an electronic device with at least two display panels, and includes the following steps: obtaining image characteristics of test images displayed on the display panels respectively; performing a parameter operation on the image characteristics separately to obtain image correction parameters correspondingly; correcting colors of the display panels respectively according to the image correction parameters; obtaining luminance characteristics of the display panels by calculating based on the image correction parameters; and adjusting the luminance of the display panels according to the luminance characteristics.

Multi-screen color correction method and electronic device using the same

A color temperature adjusting method of a display device includes follow steps: generating a color temperature curve in CIE 1931 color space according to a color temperature range, a Planckian locus and a CIE daylight locus in the CIE 1931 color space; calculating a target color coordinate at the color temperature curve corresponding to target color temperature; generating a new brightness ratio of red, green and blue, respectively, according to the target color coordinate and tristimulus values of the brightest red, the brightest green and the brightest 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 the color temperature of the display device according to the coefficients of red, green and blue.
