ABSTRACT:
Method and apparatus to reduce or eliminate stiction and image retention in interferometric display devices are disclosed. In some embodiments, a display element comprises a plurality of interferometric modulator devices configured in a matrix, each interferometric modulator device having a movable reflective layer and a plurality of supporting posts, the plurality of posts defining a post spacing distance in at least one direction that is greater for one or more interferometric modulator devices disposed adjacent to an edge of the display element than one or more interferometric modulator devices disposed nonadjacent to an edge of the display element.
