ABSTRACT:
A method is disclosed for actuating electro-mechanical ribbon elements which are suspended over a channel. The channel defines a bottom surface and 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. Additionally, an actuation voltage generator, connected to the modulator, produces a periodic high frequency voltage signal that has a frequency close to mechanical resonant frequency .function..sub.R of the ribbon elements. The signal from the modulator is applied to the ribbon elements 31 of the electro-mechanical grating device.
