Claim 3:
4. The color temperature calibration method according to claim 3, further comprising:
if it is determined that 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, adjusting the pixel values of the first sub-pixel and the second sub-pixel based on a first sub-adjustment mode;
re-obtaining measured color coordinates corresponding to the target pixel of which the pixel values of the first sub-pixel and the second sub-pixel are adjusted;
determining differences between the re-obtained measured color coordinates and the standard color coordinates, until a difference between a re-obtained measured coordinate in the first direction in the re-obtained measured color coordinates and the standard coordinate in the first direction is not greater than a third threshold, and/or a difference between a re-obtained measured coordinate in the second direction in the re-obtained measured color coordinates and the standard coordinate in the second direction is not greater than the third threshold; and
ending the color temperature calibration, wherein
the second threshold is greater than the third threshold, and the target threshold is not less than the third threshold.
