Abstract: An image processing circuit is configured to generate a first offset value according to second offset values in at least one look-up table corresponding to a starting voltage range of at least one illumination element in a display device. The image processing circuit is further configured to generate output image data according to an ending gray level value and the first offset value. The output image data is for overdriving the at least one illumination element. The second offset values correspond to a starting gray level value of a first frame and the ending gray level value of a second frame.

Abstract: A coordinate mapping method is applied to a plurality of input points of an input image and a plurality of target subpixels of a display panel. In the display panel, a first row of the target subpixels and a second row of the target subpixels are non-aligned in a vertical direction. The coordinate mapping includes the following steps. A first row of the input points are mapped to the first row of the target subpixels, and a second row of the input points are mapped to the second row of the target subpixels. The coordinates of the first row of the input points are respectively equivalent to the coordinates of the first row of the target subpixels. The coordinates of the second row of the input points are respectively equivalent to the coordinates of the second row of the target subpixels being shifted in a horizontal direction.
