Claim 9:
10. A method for driving a display panel, wherein the method is performed by a circuit, the display panel comprises a plurality of sub-pixels and a plurality of data lines, each of the sub-pixels is connected to one of the data lines, and the method comprises:
obtaining an image having a plurality of gray levels corresponding to the sub-pixels respectively;
obtaining a second sub-pixel of the sub-pixels for a first sub-pixel of the sub-pixels;
calculating a first compensation value according to the gray level corresponding to the first sub-pixel and the gray level corresponding to the second sub-pixel;
calculating a second compensation value according to a polarization state of the first sub-pixel, a polarization state of the second sub-pixel, and a difference between the gray level corresponding to the first sub-pixel and the gray level corresponding to the second sub-pixel;
calculating a gain according to a position of the first sub-pixel; and
compensating the gray level corresponding to the first sub-pixel according to the first compensation value, the second compensation value, and the gain to obtain an output gray level, and driving the first sub-pixel according to the output gray level.
