Abstract
A method is disclosed for actuating electromechanical ribbon elements which are suspended over a channel. The channel defines a bottom surface having a bottom conductive layer formed below said bottom surface. A data generator provides a data stream. The data generator is connected to a modulator for generating from said data stream a modulated bipolar voltage signal whose time average is equal to the time average of a bias voltage applied to the bottom conductive layer. The data generator and the modulator are necessary to carry out the method. The method comprises the steps of: providing a data stream; generating from said data stream a modulated bipolar voltage signal whose time average is equal to the time average of a bias voltage applied to the bottom conductive layer; and applying said modulated bipolar voltage signal to the ribbon elements.
