  • SYSTEM AND METHOD OF SENSING ACTUATION AND RELEASE VOLTAGES OF INTERFEROMETRIC MODULATORS
    Publication number: 20130321379
    Abstract: This disclosure provides methods and apparatus for calibrating display arrays. In one aspect, a method of calibrating a display array includes determining a particular drive response characteristic and updating a particular drive scheme voltage between updates of image data on the display array. The drive response characteristic may be determined by applying a ramp voltage to a line of the array and detecting a current pulse due to a capacitance change on the line. The ramp voltage generator can include a capacitor and a digitally controlled current source.
