PURPOSE: To enable address designation without using any resonance reset circuit of high voltage and high frequency and any switching device attached to that circuit and without generating any problem of adhesion, for a digital micromirror unit having the array of electromechanical picture elements. CONSTITUTION: At the first stage of this method, respective picture elements are electromechanically latched in any selected stable state by applying a bias voltage having AC and DC components to the array of picture elements. Next, the new set of selective address voltages is applied to all the picture elements. Continuously, the picture elements are electromechanically unlatched by removing the bias voltage. Next, the assumption of new state to the array of picture elements is enabled according to the new set of selective address voltages. Finally, the respective picture elements are electromechanically latched by resetting the bias voltage with the AC and DC components.
