A display device (10) has a display medium (4) and matrix type scanning (2) and data (6) electrodes which are capacitively coupled with the display medium. Display cells are defined at crossing points of scanning (2) and data (6) electrodes and the display cells can provide an electro-optical display effect in response to the application of a display voltage of a predetermined level. �<??>When a display effect is to be provided at a display cell defined at the crossing point of a selected data electrode Xa and a selected scanning electrode Ya, the selected scanning electrode Xa is set at a reference voltage (e.g. ground) the selected data electrode Xa is set at the display voltage (Va, e.g. 200V), non-selected scanning electrodes Yna are floated, so that capacitive coupling provides that they are set at a voltage higher than the reference voltage, and non-selected data electrodes (Xna) are set at a non-display voltage (Vna, e.g. 150V) which is insufficient to provide an electro-optical display effect. |
