The invention comprises systems and methods for adjusting a driving voltage based on relaxation information of a movable reflective layer of an interferometric modulator. In one example, a device fordriving a MEMS device having a movable reflective layer comprises a sensing unit configured to generate information related to one or more of time, environmental exposure, and frame rate of a movablereflective layer of at least one MEMS device, and a driver circuit configured to apply voltages to drive said at least one MEMS device, said voltages being based at least in part on said information.
