ABSTRACT:
A sheet of electroluminescent material in the shape of an alphanumeric character is embedded in a rigid base. An exciter unit for transforming incoming electric power to the appropriate voltage and frequency for driving the luminescent material is also embedded in the base behind the character. Each character, base and exciter unit thus form a self-contained display module. A universal interconnecting member is used to electrically and mechanically interconnect the module to any other module with the proper horizontal or vertical spacing. The gap between adjacent display modules may be filled with either a cover or an electrically active header which contains such devices as an electric eye for applying power to the modules after dark or a rechargable battery charged by either an external power supply or an internal solar cell.
