Abstract
The disclosure provides a voltage adjustment method and a voltage adjustment device for a display panel, and a display device. The method includes: detecting whether an absolute value of a difference between a first gray scale data of a first sub pixel and a second gray scale data of a second sub pixel in a static picture area is larger than a preset gray scale threshold; if so, acquiring the first gray scale data; and inputting a target data voltage to the data line according to the first gray scale data, to adjust an original pixel voltage to the first sub pixel into a target pixel voltage and to cause an absolute value of a difference between a first voltage difference in the positive frame and a second voltage difference in the negative frame to be smaller than a preset voltage difference threshold.
