System and method for multi-level brightness in interferometric modulation
First Claim
1. A display element, comprising:
- at least one electrode having a plurality of active areas, at least two of the sizes of the active areas being different with respect to each other; and
at least one array of interferometric modulators, selected ones of the interferometric modulators being configured to be actuated depending varying electrostatic forces in the interferometric modulators, the electrostatic forces in the interferometric modulators varying at least in part due to variations in the sizes of the active areas of electrodes in the interferometric modulators.

Abstract
A display having a plurality of reflective display elements. In one embodiment, the display elements comprise at least one electrode having a plurality of active areas. In one embodiment, at least two of the sizes of the active areas are different with respect to each other, e.g., they are non-uniform in size. The interferometric modulators have a plurality of states, wherein selected ones of the interferometric modulators are configured to be actuated depending differing electrostatic forces in the interferometric modulators. The electrostatic forces in the interferometric modulators are different at least in part due to variations in the sizes of the active areas of the electrodes.
