ABSTRACT:
The invention comprises devices and methods for driving a MEMS pixel, for example an interferometric modulator pixel. In one embodiment a device for modulating light includes a light modulator including a movable optical element positionable in two or more positions, the modulator operating interferometrically to exhibit a different predetermined optical response in each of the two or more positions, and control circuitry to provide a potential difference across the modulator, where the control circuitry is configured to incrementally increase the potential difference provided by a predetermined amount over a period of time, and where the optical element of the light modulator is moveable at least partially in response to the provided potential difference.
