Abstract: This invention relates to an apparatus and method for creating visual images on a display area. This invention uses the selective convergence of traveling electrical signals to cause selected display locations located across a display area to illuminate or to change their visual appearances. The apparatus of the invention includes a display mechanism that either illuminates or changes its visual appearance when activated, at least one signal propagation path that directs the propagation of the signals across the display area, and signal control equipment for selectively transmitting the signals. In a preferred embodiment first and second signal propagation paths provide unique propagation paths that pass through each of a the display locations across the area of the display.
