1. A display method of a display panel, the display panel comprising a plurality of sub-pixel arrays, each sub-pixel array being composed of eight sub-pixels arranged in two rows and four columns, wherein in each sub-pixel array, four sub-pixels in a same row include three color sub-pixels and one compensation sub-pixel, the three color sub-pixels include one red sub-pixel, one green sub-pixel and one blue sub-pixel, and colors of two sub-pixels in a same column are different from each other, the display method comprising steps of: displaying a required color component of red, green or blue at each sub-pixel position, wherein this step comprises causing a plurality of color sub-pixels with the same color near a sub-pixel position to display, so that the required color component is displayed at the sub-pixel position under an average effect of the color sub-pixels with the same color; and performing display compensation on each sub-pixel position, wherein this step comprises performing display compensation on a sub-pixel position by using a plurality of compensation sub-pixels near the sub-pixel position, wherein when a color component identical to the sub-pixel color of a sub-pixel position needs to be displayed at the sub-pixel position, the plurality of color sub-pixels with the same color near the sub-pixel position comprise a color sub-pixel at the sub-pixel position and a plurality of color sub-pixels with the color around the sub-pixel position, and when a color component different from the sub-pixel color of a sub-pixel position needs to be displayed at the sub-pixel position, the plurality of color sub-pixels with the same color near the sub-pixel position comprise a plurality of color sub-pixels with a required color around the sub-pixel position.
