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.

Abstract: Disclosed is a detection target positioning method and device. The method comprises: acquiring an original image and pre-processing the original image to obtain a gradation of each pixel in a target gradation image corresponding to a target region including a detection target; calculating first gradation sets corresponding to rows of pixels of the target gradation image and second gradation sets corresponding to columns of pixels of the target gradation image; and determining rows of two ends of the detection target in a column direction according to the first gradation sets, determining columns of two ends of the detection target in a row direction according to the second gradation sets, and determining a center of the detection target according to the row of two ends of the detection target in the column direction and the columns of two ends of the detection target in the row direction.
