1. A display method, which is applicable to a display panel comprising multiple rows of sub-pixels, each row of sub-pixels are formed of sub-pixels of various colors which are alternately and cyclically arranged, the sub-pixels in respective rows are arranged in the same order, and in the column direction, sub-pixels of the same color are not adjacent, wherein the display method comprises steps of: S 1 , generating a primary image based on image information, wherein the primary image is formed of virtual pixels arranged in a matrix, and each of the virtual pixels is formed of virtual sub-pixels of different colors arranged in one row; S 2 , calculating a comparison component of each sub-pixel by using primary components of comparison virtual sub-pixels of the sub-pixel, wherein comparison virtual sub-pixels of the sub-pixel include multiple virtual sub-pixels, which are adjacent to a corresponding position of the sub-pixel in the primary image and have the same color as the sub-pixel; S 3 , acquiring differences between comparison components of each sub-pixel and other sub-pixels adjacent thereto, if each of the differences between comparison components of the sub-pixel and the other sub-pixels adjacent thereto exceeds a predetermined threshold value, determining the sub-pixel as a highlighted sub-pixel; and S 4 , calculating a display component of each sub-pixel by using primary components of sampling virtual sub-pixels of the sub-pixel, wherein sampling virtual sub-pixels of the sub-pixel include multiple virtual sub-pixels, which are adjacent to a corresponding position of the sub-pixel in the primary image and have the same color as the sub-pixel, and sampling virtual sub-pixels of the highlighted sub-pixel are selected in a different manner from that for other sub-pixels.
