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.
Claims21
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.
A display comprising:
- a plurality of reflective display elements, each of the display elements having:
- a first electrode;
- and
- a second electrode having a substantially non-uniform width, wherein the second electrode spans at least two display elements.
A method comprising:
- providing a voltage to an electrode having a substantially non-uniform width;
- and
- in response to the provided voltage, activating selected ones of a plurality of reflective display elements.
A reflective display element comprising:
- a first electrode having a non-uniform width;
- and
- a second electrode, wherein the first electrode is configured to activate selected portions of the first electrode in response to varying a difference in the voltage between the first electrode and the second electrode.
A method comprising:
- varying a difference in voltage between a first electrode and a second electrode, wherein the first electrode has a non-uniform shape, and wherein the varied voltage results in a change in an optical characteristic of an interferometric modulator;
- and
- in response to the varied voltage, selectively activating or deactivating fractional portions of the second electrode.
