Abstract: A compensation method of a display panel includes controlling a first display part of a target panel to display a light load image based on a standard gamma curve, controlling a second display part of the target panel to display a heavy load image, acquiring a first brightness of a first color sub-pixels in an (N1+1)th row electrically connected to a first data line of the first display part, acquiring a second brightness of the first color sub-pixels in an (N2+1)th row of a first sub-display part of the second display part electrically connected to a second data line, and according to a difference between the first brightness and the second brightness, determining a first compensation data corresponding to the first gray scale and the second preset gray scale of at least the first color sub-pixels of the first sub-display part in the target panel.
