The present application discloses a control method for a display panel and a display panel, which adjust a shared voltage signal transmitted by the one of the sharing lines electrically connected to the auxiliary pixel electrodes of the sub-pixels corresponding to a color of color shift according to the color of color shift displayed by the display panel, so that the shared voltage signal after the adjusting is different from the shared voltage signal transmitted by the sharing lines electrically connected to the auxiliary pixel electrodes of the sub-pixels with different emission colors, so as to alleviate the problem of color shift of the display panel.
