Abstract

This disclosure provides systems methods and apparatus for calibrating and controlling the actuation of an analog interferometric modulator. In one aspect an electrode of a movable layer of the analog interferometric modulator may include a part for receiving a drive voltage and an electrically isolated part. A voltage may be sensed from the electrically isolated part and used to determine the position of the movable layer and/or provide feedback to the drive voltage.
