<p>The invention comprises devices and methods for driving a MEMs pixel, and in particular, 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 connected to the light modulator for controlling said interferometric modulator, where the control circuitry is controllably switchable between two circuit configurations, and where the control circuitry provides current to said light modulator when switching between the two circuit configurations to cause the movable optical element of the light modulator to move between two positions of its two or more positions. In another embodiment a method of driving an interferometric modulator pixel with a driving circuit includes providing a potential difference across the interferometric pixel, wherein the provided potential difference increases over a period of time, and changing the position of a movable reflective layer of the interferometric pixel based on the provided potential difference.</p> |
