Organic light-emitting display panel, driving method thereof, and driving device

The invention discloses an organic light-emitting display panel, a driving method thereof, and a driving device. After gray scale data corresponding to various pixels of a to-be-displayed image is received, and aging degrees corresponding to the various pixels are determined, and according to the gray scale data corresponding to the various pixels and the aging degrees corresponding to the various pixels, data compensation coefficients corresponding to the various pixels are determined, and then the gray scale data corresponding to the various pixels are compensated by adopting the determined data compensation coefficients corresponding to the pixels, and finally, the gray scale data corresponding to the various pixels after the compensation is used to drive the various pixels in the organic light-emitting display panel. The data compensation coefficients are determined by the gray scale data corresponding to the various pixels and the aging degrees, under the condition of the same aging degree, the pixels having the low gray scale data are provided with the high data compensation coefficients, and then the aging effect is enhanced, and the more obvious compensation effect having the low gray scale is realized, and then the organic light-emitting display panel after the compensation has uniform display effect.
