The invention discloses a display calibration method and device, a chip, electronic equipment and a storage medium. The method comprises the steps that first chromaticity coordinates corresponding to all colors are obtained when a display screen is made to be red, green and blue under respective target driving currents; obtaining a target chromaticity coordinate corresponding to each gray-scale value according to the target brightness corresponding to each gray-scale value, a preset gamma index and the target chromaticity coordinate of the white point; obtaining a target gamma value corresponding to each gray-scale value according to the first chromaticity coordinates corresponding to the three colors, a preset mapping value and the target chromaticity coordinates corresponding to each gray-scale value so as to obtain a target gamma curve; and converting the to-be-displayed gray scale data based on the target gamma curve so as to carry out picture display. The gamma curve is corrected based on the first chrom
