Screen color gamut correction method

The screen color gamut correction method comprises the following steps: acquiring screen color gamut initial values of a plurality of pixel points; converting the screen color gamut initial value of each pixel point to a CIE color gamut to obtain a CIE initial coordinate value, and converting the target color gamut value of each pixel point to the CIE color gamut to obtain a CIE target coordinate value; when the color difference between the CIE initial coordinate value and the CIE target coordinate value exceeds a preset range, performing iterative correction on the CIE initial coordinate value; and when the color difference between the corrected CIE coordinate value and the CIE target coordinate value satisfies a preset range, transmitting the corrected CIE coordinate value to the CIE initial coordinate value of the next pixel point. According to the screen color gamut correction method provided by the invention, through a method of calculating the target value through single-point iteration and carrying out
