The present invention discloses a method and apparatus for displaying a moving graphic on a display surface formed from columns of lights. The columns of lights are arranged in two or more intermingled sets and the graphic is divided into a corresponding number of parts each of which is resolved into dot elements. The dot elements of a part of the total graphic are displayed only by the lights of the corresponding set. The dot elements are displayed in a predetermined sequence of display state periods only by those lights which for each period have the correct location given the shape of the part of the graphic and the intended motion of that part. The invention enables animation to take place since parts of the graphic can move differently. In addition, colour mixing is possible as is a reduction in the number of lights reguired for a given resolution. |
