Abstract
The present disclosure provides a method and a device for obtaining display compensation information, a display compensation method and a display compensation device. The method includes: obtaining target data in a pure-color image displayed by a display panel, the display panel including a plurality of pixels, each pixel includes 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. According to the present disclosure, it is able to improve the brightness uniformity and the chromaticity uniformity of the display panel.
