11. An operation method of a processor in a display device, wherein the operation method comprises following operations:
calculating, by the processor, a total coupling coefficient for a (N−1)th frame according to input data, wherein N is a positive integer greater than 1;
calculating, by the processor, a coupling coefficient difference value of two adjacent lines for a Nth frame according to the input data;
generating, by the processor, a first compensation value for a target sub-pixel according to the coupling coefficient difference value and target input data of the target sub-pixel;
generating, by the processor, a second compensation value for the target sub-pixel according to the first compensation value and the total coupling coefficient;
generating, by the processor, an output data for the target sub-pixel according to the target input data and the second compensation value; and
controlling, by the processor, a display panel in the display device to display a final image according to the output data.
