Claim 2:
3. The color temperature calibration method according to claim 1, further comprising:
if it is determined that the difference between the re-obtained measured coordinate in the second direction and the standard coordinate in the second direction is less than the second threshold, comparing a measured coordinate in the first direction in a current state with the standard coordinate in the first direction;
if it is determined that a difference between the measured coordinate in the first direction in the current state and the standard coordinate in the first direction is not less than the second threshold, determining whether the measured coordinate in the first direction in the current state is greater than the standard coordinate in the first direction;
if it is determined that the measured coordinate in the first direction in the current state is greater than the standard coordinate in the first direction, decreasing the pixel value of the first sub-pixel;
if it is determined that the measured coordinate in the first direction in the current state is less than the standard coordinate in the first direction, increasing the pixel value of the first sub-pixel;
re-obtaining a measured coordinate in the first direction corresponding to the target pixel of which the pixel value of the first 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 second threshold, wherein

the first threshold is greater than the second threshold, and the target threshold is less than or equal to the second threshold.
