Zusammenfassung:	A compensation method and device for a display panel. The compensation method for a display panel includes acquiring a plurality of test grayscales of a to-be-tested display panel, performing a grayscale extension on the test grayscales to determine a plurality of test mapping grayscales corresponding to the test grayscales; acquiring, by using a camera, actual display brightness of each of the test mapping grayscales and actual display chroma of each of the test mapping grayscales; and determining a grayscale compensation formula of each display region of the at least two display regions of the display panel according to target display brightness of each of the test mapping grayscales, target display chroma of each of the plurality of test mapping grayscales, the actual display brightness of each of the test mapping grayscales, and the actual display chroma of each of the test mapping grayscales.
