Abstract
A method and a device for brightness compensation of a display panel, and a display device are provided. The method includes obtaining a brightness degradation rate of each sub-pixel of a plurality of sub-pixels of the display panel at a first gray-scale value. The method also includes determining whether brightness degradation rates of the plurality of sub-pixels include a brightness degradation rate greater than a first preset threshold, and whether a proportion of sub-pixels, having brightness degradation rates greater than the first preset threshold, over the plurality of sub-pixels is greater than a preset percentage. Further, the method includes performing brightness compensation on the display panel according to one of a first brightness compensation method (increasing brightness of at least a portion of the plurality of sub-pixels) and a second brightness compensation method (reducing brightness of at least a portion of the plurality of sub-pixels).
