Abstract
A system and method for staggered actuation of columns of interferometric modulators. In one embodiment, the method determines data for actuating two or more groups of columns in the array, each group having one or more columns, and provides the data to the array to actuate two or more group of columns so that each group is activated during a group addressing period. In another embodiment, a display includes at least one driving circuit and an array comprising a plurality of interferometric modulators disposed in a plurality of columns and rows, said array being configured to be driven by said driving circuit which is configured to stagger the actuation of the plurality of columns during an array addressing period.
