Abstract
To provide for alphanumeric representation, for example to indicate speed limits, traffic signals and the like, a frame forming a flat plate and defining a display surface is formed with grooves in which electromagnetically operated indicating elements are positioned, the indicating elements having differently colored regions, the colors either matching or contrasting with that of the display surface so that, either, the region surrounding the indicating element will appear blank, or have the aspect of a bar; by arranging the elements in bar codes, alphanumeric information can be provided. The indicating elements are held in any one pivoted position by permanent magnets and moved between positions by a pulse applied to a solenoid to change the position of the element from one to another stable, magnetically biassed position.
