Abstract

The embodiment of the invention discloses a display device and a brightness adjusting method and device thereof, electronic equipment and a storage medium. The display device comprises a plurality of pixel points and a memory, and the brightness adjusting method comprises the following steps: for each pixel point, obtaining a gray scale offset data set of the pixel point under m specific gray scale pictures and storing the gray scale offset data set in the memory, wherein the gray scale offset data set comprises m pieces of first gray scale offset data, and m is greater than 2; when the target gray-scale picture is displayed, calculating second gray-scale offset data of the pixel points under the target gray-scale picture according to the gray-scale offset data set of the pixel points; and compensating the gray scale of the pixel point under the target gray scale picture according to the second gray scale offset data. According to the embodiment of the invention, the gray scale compensation of each pixel point is dynamically realized, the uniformity of a multi-gray-scale picture can be considered, the multi-gray-scale overall optical compensation uniformity effect of a product is improved, the display uniformity is improved after compensation, and the invention is suitable for the gray scale compensation of the pixel point in any gray scale picture.

Description

technical field [0001] Embodiments of the present invention relate to display technologies, and in particular, to a display device, brightness adjustment method, device, electronic equipment, and storage medium thereof. Background technique [0002] During the production process of the display screen, due to material, process and other reasons, there will be some products with uneven screen brightness, that is, Mura. This uneven brightness spot will bring visual discomfort, and generally it can only be scrapped. or downgrade. By using advanced sub-pixel-level optical imaging technology and software algorithms to eliminate mura lines, that is, optical compensation Demura, the display quality of the display can meet the requirements of the panel factory's shipment specifications, and the yield rate of mass production of the display can be improved. [0003] The display uniformity of the existing optical compensation is poor, so it is still necessary to find a more accurate an...
