at least two interferometric modulators; and
a solar cell, wherein the solar cell is configured to provide energy for at least one of the interferometric modulators and is located between the at least two interferometric modulators.
2. The device of claim 1 , further comprising a capacitor, wherein the capacitor is configured to store energy from the solar cell.
3. The device of claim 1 , further comprising a battery, wherein the battery is configured to store energy from the solar cell.
4. The device of claim 1 , wherein the device comprises an array of interferometric modulators.
5. The device of claim 4 , wherein the array comprises the at least two interferometric modulators.
6. The device of claim 4 , wherein the solar cell is located outside the perimeter of the array.
7. The device of claim 1 , wherein at least one material of the interferometric modulators is the same as at least one material of the solar cell.
8. The device of claim 7 , wherein the at least one material of the interferometric modulators is the same thickness as the at least one material of the solar cell.
9. The device of claim 7 , wherein the at least one material of the interferometric modulators and the at least one material of the solar cell comprise indium tin-oxide.
10. The device of claim 7 , wherein an electrode layer of the interferometric modulators comprises the at least one material of the interferometric modulators.
11. The device of claim 1 , further comprising:
a display comprising the interferometric modulators;
a processor that is configured to communicate with said display, said processor being configured to process image data; and
a memory device that is configured to communicate with said processor.
12. The device of claim 11 , further comprising a driver circuit configured to send at least one signal to the display.
13. The device of claim 12 , further comprising a controller configured to send at least a portion of the image data to the driver circuit.
14. The device of claim 11 , further comprising an image source module configured to send said image data to said processor.
15. The device of claim 14 , wherein the image source module comprises at least one of a receiver, transceiver, and transmitter.
16. The device of claim 11 , further comprising an input device configured to receive input data and to communicate said input data to said processor.
