摘要：
A method for driving a thin film EL display device comprising the steps of clamping the Y side scanning electrodes selectively and sequentially to a reference voltage and applying the display voltage selectively from the X side data electrodes. In addition, the non-display voltage which is lower than the display threshold voltage, is applied to the non-selected data electrodes and the non-selected scanning electrodes are floated. This new driving method reduces drive power and widens the device operating voltage range.
