The invention discloses a display method, a displayer and a display device. The display method comprises the steps of: determining that a target refreshing frequency of a display panel is one of the refreshing frequencies of the display panel according to a preset triggering condition; determining a public voltage value corresponding to the target refreshing frequency according to a pre-stored relation of the refreshing frequency and the corresponding public voltage value; and applying a voltage to a public electrode of the display panel according to the determined public voltage value in a display process, and controlling the display panel to refresh with the determined target refreshing frequency. According to the embodiment of the invention, the display panel is enabled to display images in different refreshing frequencies, so that the display panel has a plurality of refreshing frequencies.
