Title:
SYSTEM AND METHOD OF SENSING ACTUATION VOLTAGE AND RELEASE VOLTAGE OF INTERFEROMETRIC MODULATOR
Document Type and Number:
Japanese Patent JP2014167638
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To compensate for a temperature dependent change in display pixel characteristics of a system including an array of interferometric modulators suitable for a display.SOLUTION: A method for determining one or both of an actuation voltage and a release voltage of a microelectromechanical device comprises: applying at least two different electric potentials to at least one electrode coupled to the device; detecting at least one electric response of the device at the at least two different electric potentials; determining, based at least in part on the response, a state of the device at the at least two different electric potentials; and determining one or both of the actuation voltage and the release voltage based at least in part on the determination of the state.
