Abstract
A drive method for a display panel, and a display apparatus. The drive method includes: when current original gray-scale values corresponding to sub-pixels in the same region are the same in a plurality of continuous display frames, converting the current original gray-scale values into a first target gray-scale value and a second target gray-scale value; in a current display frame of the plurality of continuous display frames, controlling a data voltage corresponding to the first target gray-scale value to be input to a first sub-pixel unit in the region, and controlling a data voltage corresponding to the second target gray-scale value to be input to a second sub-pixel unit in the region, where each of the first sub-pixel unit and the second sub-pixel unit includes at least one sub-pixel.
