1. A method for determining a compensation value for a local display region, applied to a terminal device comprising a screen to be compensated, comprising:
turning on the screen to be compensated, wherein the screen to be compensated comprises an aperture region and a non-aperture region;
obtaining a first display data of the aperture region and a second display data of the non-aperture region when the screen to be compensated is turned on, wherein the first display data comprises a first luminance value and a first chromaticity coordinate, and the second display data comprises a second luminance value and a second chromaticity coordinate;
determining a display ratio between the aperture region and the non-aperture region based on the first display data and the second display data; and
calculating a compensation value for performing display compensation on the aperture region based on the display ratio,
wherein the determining of the display ratio between the aperture region and the non-aperture region comprises:
based on the second luminance value and the first luminance value, determining, as the display ratio, a luminance ratio of the second luminance value of the non-aperture region to the first luminance value of the aperture region when the screen to be compensated is turned on; and
based on the first chromaticity coordinate and the second chromaticity coordinate, determining, as the display ratio, a chromaticity ratio of the second chromaticity coordinate of the non-aperture region to the first chromaticity coordinate of the aperture region when the screen to be compensated is turned on.
