A flat panel display includes scan lines, data lines, and pixels. Each pixel including at least one first subpixel and a second subpixel, the first subpixel and the second subpixel of the pixel are coupled different scan lines but coupled to the same data line. All of the first subpixels of the pixels are scanned in a first display period, and all of the second subpixels of the pixels are scanned in a second display period after all of the first subpixels are scanned. One color of subpixel is scanned at a time in the flat panel display featuring interlaced scanning. Because video data does not change obviously in general, video data of the single one color of subpixel does not obviously change. The data line is not overloaded, neither. In this way, the color cast occurring in the conventional technology does not happen anymore.
