Abstract
Systems and methods for driving a display of MEMS devices are disclosed. In one embodiment, a display includes an array comprising a plurality of interferometric modulators, and a driving circuit coupled to said array, said driving circuit configured to provide actuation signals to drive said array based on a temperature of the display. In another embodiment, a method of driving an array having a plurality of interferometric modulators configured into a display is disclosed, where the method includes sensing the temperature at a predetermined location in display, communicating a signal based on the sensed temperature to a display driver, generating an actuation signal to drive said display based on the received signal, and providing the actuation signal to the array.
