Method and system for driving interferometric modulators
First Claim
1. A display comprising:
- an array of first interferometric modulators;
one or more second interferometric modulators;
a measuring circuit configured to measure an actuation voltage of said one or more second interferometric modulators; and
a first driving circuit coupled to said array of first interferometric modulators and configured to provide driving signals to drive said array of first interferometric modulators based on the actuation voltage measured by said measuring circuit,wherein said array of first interferometric modulators and said one or more second interferometric modulators have, respectively, a first and a second electromechanical response, wherein said first and second electromechanical responses have a predetermined relationship with each other.

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.
