Abstract

A portable electronics device (110) is provided having a thin, low power color and pattern customizable housing surface (118, 120, 122) wherein the color and/or pattern can be configured at anytime to any color. The portable electronics device (110) comprises a skin (200) positioned on the surface, wherein the skin (200) includes a first plurality of layers (202, 302, 406) for selectively reflecting a first color, a second plurality of layers (204, 304, 404) for selectively reflecting a second color; and a third plurality of layers (206, 306, 402) for selectively reflecting a third color. Circuitry is positioned within the housing for receiving and storing at least one appearance feature, and for selecting one of the at least one appearance feature for presentation by the skin.

Claims

1. A portable electronic device comprising:

a housing having a surface;

circuitry positioned within the housing for receiving and storing at least one color, and for selecting one of the at least one color and providing a signal representative of the selected color; and

a skin positioned on the surface and comprising a plurality of colored layers for reflecting a plurality of colors for presenting the selected at least one color in response to the signal, the skin having an average reflectivity in the visual spectrum of greater than 30%.

2. The portable electronic device of claim 1 wherein the source comprises a camera and the portable electronic device further comprises controls wherein a color may be selected from an acquired picture taken by the camera and displayed by the skin.

3. The portable electronic device of claim 1 further comprising controls for selecting the data from a plurality of data.

4. The portable electronic device of claim 1 wherein the skin comprises a plurality of layers less than 1 mm thick.

5. The portable electronic device of claim 1 wherein the skin comprises a plurality of layers utilizing an electrowetting technology.

6. The portable electronic device of claim 1 wherein the skin comprises a plurality of layers utilizing a cholesteric liquid crystal display technology.

7. The portable electronic device of claim 1 wherein the skin comprises a battery drain of less than 30 milliwatts per day.

8. The portable electronic device of claim 1 wherein the skin comprises a color gamut greater than 50% of the SMPTE-C standard.

9. The portable electronic device of claim 1 wherein the skin may be conformed to non-planar shapes.

10. The portable electronic device of claim 1 further comprising a sensor to detect the ambient illumination for adjustment of the shade of the selected color.

11. The portable electronic device of claim 1 wherein the skin comprises multiple addressable regions for displaying patterns.

12. The portable electronic device of claim 1 further comprising a transparent protective layer overlying the skin.

13. The portable electronic device of claim 1 wherein the manufacturing cost of the skin is less than half the cost of the power source.

14. The portable electronic device of claim 1 wherein the portable electronic device comprises a cellular telephone.

15. A portable electronic device having a surface, comprising:

a source of data defining at least one appearance feature;

a microprocessor for processing the source data and providing a signal representative of the at least one appearance feature; and

a skin positioned over the surface and responsive to the signal for displaying the at least one appearance feature,

wherein the skin uses less than 40% of the amount of power the portable electronic device'"'"'s power source can provide in a day.

16. The portable electronic device of claim 15 wherein the source comprises a camera and the portable electronic device further comprises controls wherein the appearance feature comprises a color that may be selected from an acquired picture taken by the camera and displayed by the skin.

17. The portable electronic device of claim 15 further comprising controls for selecting the data from a plurality of data.

18. The portable electronic device of claim 15 wherein the skin reflects three colors having an average reflectivity in the visible spectrum greater than thirty percent.

19. The portable electronic device of claim 15 wherein the skin comprises a plurality of layers less than 1 mm thick.

20. The portable electronic device of claim 15 wherein the skin comprises a plurality of layers utilizing an electrowetting technology.

21. The portable electronic device of claim 15 wherein the skin comprises a plurality of layers utilizing a cholesteric liquid crystal display technology.

22. The portable electronic device of claim 15 wherein the skin comprises a battery drain of less than 30 milliwatts per day.

23. The portable electronic device of claim 15 wherein the skin may be conformed to non-planar shapes.

24. The portable electronic device of claim 15 wherein the skin comprises multiple addressable regions for displaying the at least one appearance feature as a pattern.

25. The portable electronic device of claim 15 wherein the manufacturing cost of the skin is less than half the cost of the power source.

26. The portable electronic device of claim 15 wherein the portable electronic device comprises a cellular telephone.

27. A portable electronic device comprising:

a housing having a surface;

a skin positioned on the surface and comprising;

a first plurality of layers for selectively reflecting a first color;

a second plurality of layers for selectively reflecting a second color; and

a third plurality of layers for selectively reflecting a third color;

a material formed between the skin and the surface, the material being either white or black in color; and

circuitry positioned within the housing for receiving and storing at least one appearance feature, and for selecting one of the at least one appearance feature for presentation by the skin.

28. The portable electronic device of claim 27 wherein the first, second, and third plurality of layers each comprise:

a first electrode;

a second electrode; and

an oil positioned between the first and second electrode, wherein light entering the skin passes through the oil when no voltage is applied to the first and second electrodes, and the oil migrates when a voltage is applied to the first and second electrodes with most of the light bypassing the oil.

29. The portable electronic device of claim 27 wherein the first, second, and third plurality of layers each comprise:

a first electrode;

a second electrode; and

a layer of cholesteric liquid crystal material positioned between the first and second electrode.
