ABSTRACT:
Methods and apparatus are provided for preventing charge accumulation in microelectromechanical systems, especially in micromirror array devices having a plurality of micromirrors. Voltages are applied to the micromirrors for actuating the micromirrors. Polarities of the voltage differences between mirror plates and electrodes are inverted so as to prevent charge accumulation.
