Claim:
1. A method for presenting an image on a display, wherein the display has a pixel array which is composed of a plurality of basic pixel units which are repeated in a horizontal direction and a vertical direction, wherein each of the basic pixel units comprises a first pixel point, a second pixel point and a third pixel point which are arranged from top to bottom, the first pixel point is composed of a first sub-pixel of a first color and a second sub-pixel of a second color which are respectively located in two different horizontal rows, the second pixel point is composed of a third sub-pixel of a third color and a first sub-pixel of the first color which are respectively located in two different horizontal rows, and the third pixel point is composed of a second sub-pixel of the second color and a third sub-pixel of the third color which are respectively located in two different horizontal rows, wherein: the first sub-pixel in the first pixel point, the third sub-pixel in the second pixel point, and the second sub-pixel in the third pixel point are arranged in sequence from top to bottom in the vertical direction at a first interval to form a first column; the second sub-pixel in the first pixel point, the first sub-pixel in the second pixel point, and the third sub-pixel in the third pixel point are arranged in sequence from top to bottom in the vertical direction at the first interval to form a second column; and the second column is separated from the first column by a second interval in the horizontal direction; wherein the method comprises: (a) inputting image signals representative of a color image to be presented on the display; (b) generating an intensity map which comprises intensity values of each first sub-pixel, each second sub-pixel and each third sub-pixel of the display; and (c) outputting a plurality of electrical signals generated according to the intensity map to the display; wherein, after step (a) and before step (b), the method further comprises: generating at least one color template, wherein the at least one color template is used to generate the intensity map; wherein the color template comprises: a first sub-pixel at a center of the color template and having a first brightness value; a second sub-pixel in a sub-pixel row next to the first sub-pixel and having a second brightness value; and a third sub-pixel in a sub-pixel row preceding the first sub-pixel and having a third brightness value; wherein the first sub-pixel and the second sub-pixel in the color template form a pixel point; and wherein each pixel point shares a sub-pixel having a color absent in the pixel point with an adjacent pixel point in the vertical direction so as to cooperatively realize a white display effect.
