抗静电电极

Anti-stiction electrode
Abstract:
Anti-stiction systems may include one or more anti-stiction electrodes driven to provide an electrical force that counteracts a stiction force acting upon a moveable portion of an interferometric modulator. The anti-stiction electrode(s) may be disposed on a back glass or on another such substrate. The anti-stiction electrode(s) may be configured to apply an electrical force to substantially all of the interferometric modulators in a display device at once and/or may be configured to apply an electrical force only to a selected area. In some embodiments, the sum of an anti-stiction electrical force and a mechanical restoring force of a moveable part of an interferometric modulator is sufficient to counteract a stiction force.
