ABSTRACT:
A display of a series line organized images is provided in which the images are spread across a plurality of linearly arranged display devices and appear to be shifting from one display device to the next. The line organized images are first formed into a two dimensional display in which the images scroll along lines directed along one dimension and are wrapped from one line to the next along the other dimension. For example, the images may represent alphanumeric characters which scroll from one end of a row to the other end and, when scrolling off one row, are wrapped to the next row. This image is then expanded so that an image line fills a display device along the other dimension. This expanded image is then applied to the display devices so that each display device receives the expanded image with a predetermined shift along the one dimension relative an immediately adjacent display device.
