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 sub-pixel arrangement structure of an organic light emitting diode display including a plurality of sub-pixels is provided. The plurality of sub-pixels are arranged in a first direction and a second direction to form a sub-pixel array. The first direction is inclined at a first angle relative to a reference direction, and the second direction is inclined at a second angle relative to the reference direction. Each four sub-pixels of the plurality of sub-pixels form a virtual quadrangle. The each four sub-pixels include two sub-pixels having a same color, and the two sub-pixels having the same color are arranged at adjacent vertexes of the virtual quadrangle in one of the first direction and the second direction.

Abstract: A method of compensating luminance of an organic light-emitting diode (OLED) operated with a transistor in a pixel cell of a display panel includes measuring a first parameter of the transistor and a parameter of the OLED, and generating a lookup table accordingly; converting original display data to target display data according to the lookup table; outputting the target display data to the pixel cell; and compensating a second parameter of the transistor when the target display data is received by the pixel cell.
