Claim 6:
7. A non-transitory computer-readable storage medium storing therein a computer program, wherein the computer program is executed by a processor so as to implement a method for obtaining display compensation information, the method comprising:
obtaining target data in a pure-color image displayed by a display panel, the display panel comprising a plurality of pixels, each pixel comprises a plurality of monochromatic light-emitting elements in various colors, each monochromatic light-emitting element in a corresponding color being configured to display an image at a highest grayscale value when the pure-color image is displayed by the display panel;
determining a conversion matrix for a target gamut of the display panel and a pixel conversion matrix for each pixel in accordance with the target data; and
determining a uniformity conversion matrix for performing brightness and chromaticity uniformity compensation on each pixel in accordance with the pixel conversion matrix and the conversion matrix for the target gamut,
wherein the target data comprises chromaticity coordinates and a brightness value of the monochromatic light-emitting element,
wherein the determining the conversion matrix for the target gamut of the display panel in accordance with the target data comprises:
obtaining a minimum brightness value in brightness values of all the monochromatic light-emitting elements in a same color as a target brightness value; and
determining the conversion matrix for the target gamut of the display panel in accordance with the target brightness value and target chromaticity coordinates of the monochromatic light-emitting element in each color.
