Abstract
A gamma adjustment method and an adjustment device for a display panel. The gamma adjustment method describes that if the absolute value of the gamma voltage corresponding to the current grayscale binding point is smaller than the absolute value of the gamma voltage corresponding to the previous grayscale binding point, obtaining absolute values of gamma voltages corresponding to at least two grayscale binding points located previous to the current grayscale binding point. Obtaining a first relationship curve by fitting the respective grayscales corresponding to the at least two grayscale binding points and the absolute values of the gamma voltages corresponding to the at least two grayscale binding points, and adjusting the gamma voltage corresponding to the current grayscale binding point to locate the absolute value of the adjusted gamma voltage corresponding to the current grayscale binding point on the first relationship curve.
