Method and device for obtaining display compensation information, and display compensation method and device

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.
