Abstract
A chromaticity compensation method, a chromaticity compensation device and a storage medium are disclosed. The chromaticity compensation method includes that, according to a preset standard chromaticity value and measured chromaticity values corresponding to a plurality of sub-display regions in a display region, chromaticity compensation values of the sub-display regions are determined, and the display region is divided into the plurality of sub-display regions in close arrangement, and each of the sub-display regions includes a plurality of sub-pixels; a data smoothing treatment is performed between the chromaticity compensation values of the sub-display regions that are adjacent, so as to determine the smoothed chromaticity compensation values of the sub-pixels in the sub-display regions; and upon display, chromaticity compensation of the sub-pixels are performed by adopting the smoothed chromaticity compensation values.
