Claim 6:
7. The color temperature calibration method according to claim 6, wherein the first method includes:
determining whether the difference between the measured coordinate in the first direction and the standard coordinate in the first direction is less than the first threshold;
if it is determined that the difference between the measured coordinate in the first direction and the standard coordinate in the first direction is not less than the first threshold, decreasing the pixel value of the third sub-pixel, re-obtaining a measured coordinate in the first direction corresponding to the target pixel of which the pixel value of the third sub-pixel is adjusted, and determining a difference between the re-obtained measured coordinate in the first direction and the standard coordinate in the first direction, until the difference between the re-obtained measured coordinate in the first direction and the standard coordinate in the first direction is less than the first threshold;
if it is determined that the difference between the measured coordinate in the first direction and the standard coordinate in the first direction is less than the first threshold, determining whether the measured coordinate in the second direction is greater than the standard coordinate in the second direction;
if it is determined that the measured coordinate in the second direction is greater than the standard coordinate in the second direction, decreasing the pixel value of the second sub-pixel;
if it is determined that the measured coordinate in the second direction is less than the standard coordinate in the second direction, increasing the pixel value of the second sub-pixel;
re-obtaining a measured coordinate in the second direction corresponding to the target pixel of which the pixel value of the second sub-pixel is adjusted; and
determining a difference between the re-obtained measured coordinate in the second direction and the standard coordinate in the second direction, until the difference between the re-obtained measured coordinate in the second direction and the standard coordinate in the second direction is less than a second threshold.
