Claim 4:
5. The electronic device according to claim 1, wherein the target data comprises chromaticity coordinates and a brightness value of the monochromatic light-emitting element, and the determining the pixel conversion matrix for each pixel comprises:
dividing all the grayscale values capable of being displayed into N grayscale sections with respect to the monochromatic light-emitting element in each color, N being a positive integer greater than or equal to 2;
determining a chromaticity coordinates fluctuation coefficient for each of the N grayscale sections in accordance with a fitted curve indicating a change in the chromaticity coordinates of the monochromatic light-emitting element with a current and extracted chromaticity coordinates of the monochromatic light-emitting element at the highest grayscale value; and
determining the pixel conversion matrix for each pixel in accordance with the chromaticity coordinates fluctuation coefficient.
