1. A method for controlling displaying in a display panel, wherein the display panel comprises a planar region and a curved edge region, and the method comprises:
determining, for each curved region of a plurality of curved regions, a central pixel among all pixels in said curved region, wherein the curved edge region is divided into the plurality of curved regions;
determining a plurality of gray-scale combinations;
determining chromaticity coordinates of the central pixel of each curved region under each gray-scale combination of the plurality of gray-scale combinations;
determining reference chromaticity coordinates of a target pixel in the planar region under a maximum gray-scale combination among the plurality of gray-scale combinations;
determining, for each curved region, a target gray-scale combination among the plurality of gray-scale combinations based on a difference between the reference chromaticity coordinates and the chromaticity coordinates of the central pixel of said curved region under each gray-scale combination; and
controlling displaying in each curved region based on the target gray-scale combination of said curved region.
