Abstract:
An image-creating implement comprising:a plurality of light sources arranged in a one-dimensional matrix, said one-dimensional matrix comprising a vertical column and a plurality of horizontal rows in which each of said horizontal rows has no more than one of said light sources;a power supply;electronic circuitry adapted to blink each of said light sources at said light source's safe maximum current in a manner such that when said matrix is moved an observer thereof will observe a two-dimensional image, wherein the electronic circuitry comprises neither a line driver nor a current limiting device and provides an imagetime for each of said light sources within the range from about 30 milliseconds to about 200 milliseconds, said imagetime comprising a plurality of displaytimes, and said electronic circuitry further providing that when a light source is on for a particular displaytime that the light source has an LED On time equal to said particular displaytime, wherein the light sources and the electronic circuitry are not damaged when said light sources are on for said image time.
