摘要： 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.

摘要： An LCD Driver System (10) includes a row decoder (38) for providing command signals to row drivers (50) and a RAM row decoder (64) for controlling a RAM (76) which supplies data to a column driver (88). The row and column drivers (50 and 88) are supplied with power by a power source (58) which can supply either high or low voltages. In normal mode, the power source (58) supplies high voltage and the row driver (50) drives both a dot matrix portion (14) and an icon portion (16) of an LCD display. In an icon mode, a disable signal disables the row decoder (38) and the RAM row decoder (64), enables only the icon row driver (54) of the row drivers (50) and the icon row of the RAM (76) and switches the power source (58) to supply low voltage so as to save power.
