Abstract: An image processing method and a display device thereof are provided. The method is adapted to a display panel with a display area. The image processing method includes the following steps. Whether original images to be displayed on a plurality of sub-areas of the display area are still is analyzed and determined. When the original image in a current sub-area is still, a time length of the original image being still is recorded. The current sub-area is one of the sub-areas. Processing levels corresponding to a plurality of image processing schemes are determined based on the time length. Overall or partial luminance (luma) of the original image in the current sub-area is gradually reduced by the image processing schemes with the determined processing levels, and a corresponding luma-reduced image is displayed on the current sub-area.

Abstract: A display panel and a display driver are provided. The display panel includes a plurality of sub-pixel repeating units, which are arranged repeatedly to form a pixel array. Each row of the sub-pixel repeating unit includes an odd number of sub-pixels, where every two sub-pixels are regarded as one pixel unit, and another sub-pixel is added at the last column of the sub-pixel repeating unit. The odd-numbered sub-pixels are respectively written by N groups of pixel data. The amount of these sub-pixels is 2N+1, which is between two to two and a half times of the amount of the pixel data. Each odd-numbered column of the sub-pixel repeating unit includes the sub-pixels of two different colors, which are alternately arranged in each odd-numbered column.
