Display panel, display device and control method of display panel

The present invention relates to a display panel, a display device and a control method of the display panel. The display panel includes a first electrode layer, a first insulating layer, a plurality of sub-pixels, a second insulating layer and a second electrode layer; a first sub-pixel and a second sub-pixel adjacent thereto in the plurality of sub-pixels respectively include a colored fluid layer and a transparent conductive fluid; the colored fluid layer in the first sub-pixel comprises a first colored fluid layer of a first color and a second colored fluid layer of a second color, wherein the second color is a complementary color of the first color, and one of the second color and the first color is one of three primary colors; the colored fluid layer in the second sub-pixel comprises a third colored fluid layer of a third color and a fourth colored fluid layer of a fourth color, wherein the fourth color is a complementary color of the third color, and one of the fourth color and the third colored is another color in the three primary colors; a common voltage is applied to the transparent conductive fluid; and a driving voltage can be applied to each of the first colored fluid layer, the second colored fluid layer, the third colored fluid layer and the fourth colored fluid layer through electrodes corresponding to the first colored fluid layer, the second colored fluid layer, the third colored fluid layer and the fourth colored fluid layer, so that the first colored fluid layer, the second colored fluid layer, the third colored fluid layer and the fourth colored fluid layer can contract or stretch.
