Abstract
A method of creating an image for an event or promotion involves providing a plurality of light sources arranged in a one-dimensional matrix. The one-dimensional matrix is made up of a vertical column and at least two horizontal rows. The light sources are blinked for at least two image_times that are within the range from about 30 milliseconds to about 200 milliseconds without use of a line driver. The power source is selected to avoid damaging the light sources or electronic circuity controlling the light sources. Each of the image_times includes two or more display_times that are equal to LED On time. The light sources are moved relative to an observer at the event or promotion, such that the observer will observe a two-dimensional image.
