description 1. Field of the Invention A driving system and its corresponding driving scheme for electroluminescence displays that employs the principle of electric charge conservation and recycling in order to reduce switching current requirement against the system power source. In an electroluminescence display of a matrix of electroluminescence elements arrayed in rows and columns, wherein anodes of the electroluminescence elements on each row being electrically connected to a corresponding anode line, and cathodes of the electroluminescence elements on each column being electrically connected to a corresponding cathode line, a driving system for driving said electroluminescence display comprises a row/column control circuit for lighting at least one of said electroluminescence elements by establishing an electrical route across the power source and the ground in a driving scheme. The driving scheme sequentially scans each of the cathode lines while simultaneously drives at least one of the anode lines during each scanning. The control circuit equalizes electric charges in electroluminescence elements in the cathode line being scanned and in an adjoining cathode line to be scanned subsequently by electrically connecting both cathode lines together before the scanning cycles to the adjoining cathode line.
