y＝-3.000*x^2+2.870*x-0.275；
If Tc >7000K, then
x＝-2.0064*g^3+1.9018*g^2+0.24748*g+0.237040；

when performing the coordinate conversion, a preset relation may be adopted to perform conversion from RGB coordinates to XYZ coordinates on the current RGB values of the display device, and calculate the tristimulus values X, Y, Z corresponding to the current RGB values in the XYZ coordinate system, where the relation between X, Y, Z and R, G, B in the preset relation is as follows:
X＝Xr*R+Xg*G+Xb*B；
Y＝YrR+Yg*G+Yb*B；
Z＝ZrR+Zg*G+Zb*B；

then, obtaining the current color temperature value of the display equipment according to the current RGB value of the display equipment;
the derivation logic for obtaining the current color temperature value of the display device according to the current RGB value of the display device is as follows:
the relation between the color temperature CCT and the chromaticity coordinate values x and y in the CIE1931 coordinate system is obtained according to data statistics and an empirical formula as follows:
CCT＝437*((x-0.332)/(0.1858-y))^3+3601*((x-0.332)/(0.1858-y))^2+6831*(x-0.332)/(0.1858-y)+5517；
x＝X/(X+Y+Z)；
y＝Y/(X+Y+Z)；
wherein, x and y are chromaticity coordinate values of a certain color in a CIE1931 coordinate system;
x, Y, Z is the tristimulus value corresponding to the color in XYZ coordinate system;
and X, Y, Z and R, G, B are related as follows:

Z＝ZrR+Zg*G+Zb*B；
r, G, B is the tristimulus value corresponding to the color in RGB coordinate system;
wherein, Xr, Xg, Xb, Yr, Yg, Yb, Zr, Zg, Zb are conversion coefficients.
Therefore, the relationship between RGB and color temperature can be obtained through the derivation logic, and the current color temperature value of the display equipment can be obtained according to the current RGB value of the display equipment.
Then, comparing the current color temperature value of the display equipment with the target color temperature value;
and when the current color temperature value of the display equipment is different from the target color temperature value and the difference value between the current color temperature value and the target color temperature value does not reach a preset threshold value, adjusting the current RGB value of the display equipment, and obtaining the current color temperature value of the display equipment again according to the current RGB value of the display equipment, so as to carry out iteration circularly until the difference value between the current color temperature value of the display equipment and the target color temperature value reaches the preset threshold value.
