Abstract: The present disclosure provides a method and apparatus for driving a display panel, and a display device. The method includes: upon driving an ith row of sub-pixels, scanning a gate line connected to a jth row of sub-pixels, and determining a reference grayscale of each of the jth row of sub-pixels in each candidate connection mode, wherein a plurality of data lines have a plurality of candidate connection modes; determining a target connection mode that minimizes a grayscale variation degree of the jth row of sub-pixels from the plurality of candidate connection modes; connecting the plurality of data lines according to the target connection mode; and disconnecting the plurality of data lines before driving the jth row of sub-pixels through the plurality of data lines.
