Abstract

A portable viewing and computing apparatus. In one embodiment, the present invention is comprised of a bus, a memory unit coupled to the bus, and a processor coupled to the bus. The memory unit is for storing data and instructions. The processor is for processing data and instructions. The portable viewing and computing apparatus is further comprised of a display device coupled to the bus. The display device is comprised of a viewing panel viewable from a front side and a back side. The portable viewing and computing apparatus is further comprised of a display device controller coupled to the bus. The display device controller is for sensing the orientation and rotation of the display device, and in response thereto, for controlling and rendering data on the display device.

2. The portable electronic device of claim 1, wherein said sensed rotation comprises a flip of said display device.

3. The portable electronic device of claim 1, wherein said display controller is further operable to initiate display of a third portion of information for viewing from said second side in response to a third rotation of said display device in a second direction.

4. The portable electronic device of claim 3, wherein said first and second directions are opposite directions.

5. The portable electronic device of claim 3, wherein said first, second, and third portions of information comprise consecutive portions of information, wherein said second portion of information comprises information subsequent to said first portion of information, and wherein said third portion of information comprises information preceding said first portion of information.

6. The portable electronic device of claim 1, wherein said first and second portions of information comprise consecutive portions of text from a document.

7. The portable electronic device of claim 1, wherein said first portion of information comprises text from a first page of a document, wherein said second portion of information comprises text from a second page of said document, and wherein said first and second pages of said document are consecutive pages of said document.

8. The portable electronic device of claim 1 further comprising:

a housing physically coupled to said display; and

a hinge interface connector for interfacing with said housing and operable to remain stationary while said display device and said housing are rotated, said hinge interface connector further operable to physically couple to another portable electronic device.

9. The portable electronic device of claim 8, wherein said hinge interface connector is further operable to communicatively couple said display controller to said another portable electronic device, wherein said hinge interface connector is further operable to communicate information generated by said another portable electronic device for display on said display device.

10. The portable electronic device of claim 1, wherein said display device comprises a component selected from a group consisting of a flat panel display, a transparent display, electronic paper, a flexible touch screen, and a flexible fiber display.

11. A method of displaying information, said method comprising:

displaying, in response to a first rotation of a display device in a first direction, a first portion of information for viewing from a first side of said display device of a portable electronic device, wherein said display device is operable to be rotated a plurality of times in said first direction; and

displaying, in response to a second rotation of said display device in said first direction, a second portion of information for viewing from a second side of said display device.

12. The method of claim 11, wherein said rotation comprises a flip of said display device.

13. The method of claim 11 further comprising:

in response to a third rotation of said display device in a second direction, displaying a third portion of information for viewing from said second side of said display device.

14. The method of claim 13, wherein said first, second, and third portions of information comprise consecutive portions of information, wherein said second portion of information comprises information subsequent to said first portion of information, and wherein said third portion of information comprises information preceding said first portion of information.

15. The method of claim 13, wherein said first and second directions are opposite directions.

16. The method of claim 11,

wherein said first and second portions of information comprise consecutive portions of text from a document.

17. The method of claim 11, wherein said first portion of information comprises text from a first page of a document, wherein said second portion of information comprises text from a second page of said document, and wherein said first and second pages of said document are consecutive pages of said document.

18. The method of claim 11 further comprising:

communicatively coupling said display device to another portable electronic device using a hinge interface connector;

communicating information generated by said another portable electronic device to said display device using said hinge interface connector; and

displaying said information on said display device.

19. A system comprising:
