Description

ABSTRACT:
The width and location of a hysteresis window of an interferometric modulator may be altered by adjusting various physical characteristics of the interferometric modulator. Thus, depending on the particular application for which the interferometric modulators are manufactured, the width and location of the hysteresis window may be altered. For example, in some applications, reducing the power required to operate an array of interferometric modulators may be an important consideration. In other applications, the speed of the interferometric modulators may be of more importance, where the speed of an interferometric modulator, as used herein, refers to the speed of actuating and relaxing the moveable mirror. In other applications, the cost and ease of manufacturing may be of most importance. Systems and methods are introduced that allow selection of a width and location of a hysteresis window by adjusting various physical characteristics.
