Due to the bi-stable nature of interferometric modulator elements, the state of each modulator element may be held at either an actuated or a released state with a common voltage difference. Because modulator elements often require less time to change states than is allotted in a line time, power drawn by an array of modulator elements may be reduced by disabling one or both of a row and column voltage boost module, which are configured to amplify an input power source to a level that is suitable for driving modulator elements. If the column voltage is removed during the latter portion of a line time, for example, the row voltage is set to a level that is sufficient to maintain a voltage difference between the row voltage and the floating column voltage within a stability voltage range during the remainder of the line time.
