1. A display method applied to a display panel, wherein the display panel comprises a plurality of rows of sub-pixels, sub-pixels in each row being formed by cyclically arranging sub-pixels of three colors, and cyclical orders of the sub-pixels in respective rows being equal; adjacent sub-pixels in a column direction having different colors and being staggered from each other by ½ of the sub-pixel in a row direction, wherein the display method comprises following steps: S 1 , generating an original image composed of a matrix of virtual pixels; S 2 , enabling the virtual pixels to correspond to sampling locations, wherein among the sampling locations in each row, the sampling locations corresponding to the virtual pixels are distributed in a plurality of distribution sections, wherein one sampling location is included between any two adjacent sampling locations corresponding to the virtual pixels in each distribution section, three sampling locations are included between two adjacent distribution sections; among the sampling locations in any two adjacent rows, the sampling locations corresponding to the virtual pixels are not arranged in a same column, wherein each sampling location corresponds to a location between two adjacent sub-pixels in one row and a central location of a sub-pixel in another row; and S 3 , calculating a display component of each sub-pixel in accordance with original components of corresponding colors of the virtual pixels corresponding to the sub-pixel, wherein, in any two adjacent rows of sampling locations, in one row, each distribution section has two sampling locations corresponding to the virtual pixels; and in the other row, two distribution sections at two ends of the other row have one and three sampling locations corresponding to the virtual pixels, respectively, while each of other distribution sections has two sampling locations corresponding to the virtual pixels.
