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.

Abstract: An alignment deviation detection method and apparatus of a display panel, a data compensation method and apparatus. The method includes: providing a first data signal for causing the dimming screen to display an alignment dimming picture including a first alignment pattern; providing a second data signal for causing the display screen to display an alignment display picture including a second alignment pattern; under a control of the first data signal, making the dimming screen display the alignment dimming picture, and under a control of the second data signal, making the display screen display the alignment display picture; according to a display situation of the second alignment pattern, determining an alignment state between the display screen and the dimming screen. An orthographic projection of the second alignment pattern on the dimming screen is preset to be at least partially aligned with and at least partially deviated from the first alignment pattern.

Abstract: A display method, a display device, a display system, and a storage medium are provided. The display method includes: obtaining a first fixation coordinate transmitted by an image acquisition device, and obtaining a second fixation coordinate and a current frame of image that are transmitted by a first processor; performing refresh and display by using the current frame of image; determining a type of the current frame of image, and determining, based on the type, whether the first fixation coordinate changes abnormally; and performing refresh and display by using a previous frame of image for non-fixation region in a case that the first fixation coordinate changes abnormally, and performing refresh and display by using a next frame of image transmitted by the first processor in a case that the first fixation coordinate does not change abnormally.
