1. A light modulator comprising:
- an array of elements at least some of which have different values of deflection versus addressing pulse width; and
addressing circuitry configured to provide addressing pulses of varying width to the array of elements such that different combinations of elements switch in a selectable manner, depending upon the width of the addressing pulses.

Abstract
A system and method for addressing an array of MEMS display elements, such as interferometric modulators, from a drive control. A display includes groups of display elements that are addressed with a commonly applied drive signal. In one embodiment, the groups of display elements are configured to have different response times and are driven by pulses of varying length indicative of those response times. In another embodiment, the groups of display elements are configured to have different actuation voltages and are driven by pulses of varying voltage indicative of those actuation voltages.
