Abstract

The present invention provides a display method of a display panel. The display panel in the present invention includes a plurality of repeat units each comprising a first, a second and a third color sub-pixels sequentially arranged in a row. The display method includes steps: determining a first, a second and a third color components of each repeat unit; obtaining a first and a second distribution ratios of one repeat unit respectively according to each ratio of the first color component to the second color component and of the second color component to the third color component in their respective common units; and determining respective display components of the first to the third color sub-pixels of the one repeat unit according to a total value of the first to the third color components of the one repeat unit as well as the first and the second distribution ratios.
