The method includes: obtaining brightness-unevenness information of a display panel and a plurality of gray-scale compensation data for compensating brightness-unevenness of the display panel; storing the plurality of gray-scale compensation data in a manner of a compensation table with a plurality of compensation data groups having different compensation distances being associated with the same number of data bits and in both vertical and horizontal directions; reading the plurality of compensation data groups from the compensation table and compensating gray-scale data to-be-displayed to obtain compensated gray-scale data, after the display panel is powered on; and outputting the compensated gray-scale data for picture display. Through a dynamic variable block size mode, a block size of 8×8 pixels is used for a conventional brightness-unevenness, and a block size with a higher precision is selected for a smaller brightness-unevenness."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Brightness-unevenness compensation method and device, and display panel","description":"A brightness-unevenness compensation method and device and a display panel are provided.
