Abstract

A mobile communication device includes a display that may be extended to provide a larger display surface for displaying information to a user of the mobile communication device. The mobile communication device comprises a housing assembly including a first housing portion and a second housing portion. The second housing portion is interconnected with the first housing portion so that the second housing portion slides between a retracted position and an extended position. A display is positioned within the second housing portion so that at least a substantial portion of the display is held behind the first housing portion when the second housing portion is in the retracted position and at least a substantial portion of the display is viewable by a user of the mobile communication device when the second housing portion is in the extended position.

Claims

1. A mobile communication device, comprising:

a housing assembly including a first housing portion and a second housing portion, the second housing portion being interconnected with the first housing portion so that the second housing portion slides between a retracted position wherein the second housing portion is substantially disposed behind the first housing portion and an extended position wherein the second housing portion is at least partially extended from behind the first housing portion; and

a display disposed in the second housing portion for displaying information to a user of the mobile communication device,

wherein display is positioned within the second housing portion so that at least a substantial portion of the display is held behind the first housing portion when the second housing portion is in the retracted position and at least a substantial portion of the display is viewable by a user of the mobile communication device when the second housing portion is in the extended position.

2. The mobile communication device as claimed in claim 1, further comprising a keypad assembly disposed in the first housing portion.

3. The mobile communication device as claimed in claim 1, further comprising:

a window disposed in the first housing portion for allowing the user to view at least part of the display while the second housing portion is in the retracted position,

wherein the displayed information is mapped to the display so that the information is viewable through the window while the second housing portion is in the retracted position.

4. The mobile communication device as claimed in claim 3, further comprising a keypad disposed in the first housing portion adjacent to the window.

5. The mobile communication device as claimed in claim 3, wherein the window comprises a second display, the second display being semi-transparent so that information displayed by the display is viewable through the window.

6. The mobile communication device as claimed in claim 3, wherein the displayed information is mapped to an area of the display within the window while the second housing portion is in the retracted position, and wherein the displayed information is mapped to the full display while the second housing portion is in the extended position.

7. The mobile communication device as claimed in claim 1, wherein a portion of the display extends from behind the first housing portion while the second housing portion is in the retracted position.

8. The mobile communication device as claimed in claim 7, wherein the displayed information is mapped to the portion of the display extending from behind the first housing portion while the second housing portion is in the retracted position, and wherein the displayed information is mapped to the full display while the second housing portion is in the extended position.

9. The mobile communication device as claimed in claim 7, further comprising a keypad disposed in the first housing portion.

10. The mobile communication device as claimed in claim 1, further comprising a second display disposed in the first housing portion.

11. The mobile communication device as claimed in claim 10, further comprising a keypad disposed in the first housing portion.

12. A mobile telephone, comprising:

a housing assembly including a first housing portion and a second housing portion, the second housing portion being interconnected with the first housing portion so that the second housing portion slides between a retracted position wherein the second housing portion is substantially disposed behind the first housing portion and an extended position wherein the second housing portion is at least partially extended from behind the first housing portion; and

a display disposed in the second housing portion for displaying information to a user of the mobile communication device,

wherein display is positioned within the second housing portion so that at least a substantial portion of the display is held behind the first housing portion when the second housing portion is in the retracted position and at least a substantial portion of the display is viewable by a user of the mobile communication device when the second housing portion is in the extended position.

13. The mobile telephone as claimed in claim 12, further comprising a keypad assembly disposed in the first housing portion.

14. The mobile telephone as claimed in claim 12, further comprising:

a window disposed in the first housing portion for allowing the user to view at least part of the display while the second housing portion is in the retracted position,

wherein the displayed information is mapped to the display so that the information is viewable through the window while the second housing portion is in the retracted position.

15. The mobile telephone as claimed in claim 14, further comprising a keypad disposed in the first housing portion adjacent to the window.

16. The mobile telephone as claimed in claim 14, wherein the window comprises a second display, the second display being semi-transparent so that information displayed by the display is viewable through the window.

17. The mobile telephone as claimed in claim 14, wherein the displayed information is mapped to an area of the display within the window while the second housing portion is in the retracted position, and wherein the displayed information is mapped to the full display while the second housing portion is in the extended position.

18. The mobile telephone as claimed in claim 12, wherein a portion of the display extends from behind the first housing portion while the second housing portion is in the retracted position.

19. The mobile telephone as claimed in claim 18, wherein the displayed information is mapped to the portion of the display extending from behind the first housing portion while the second housing portion is in the retracted position, and wherein the displayed information is mapped to the full display while the second housing portion is in the extended position.

20. The mobile telephone as claimed in claim 18, further comprising a keypad disposed in the first housing portion.

21. The mobile telephone as claimed in claim 12, further comprising a second display disposed in the first housing portion.

22. The mobile telephone as claimed in claim 21, further comprising a keypad disposed in the first housing portion.

23. A mobile communication device, comprising:

a housing assembly including a first housing portion and a second housing portion, the second housing portion being interconnected with the first housing portion;

means for sliding the second housing portion between a retracted position wherein the second housing portion is substantially disposed behind the first housing portion and an extended position wherein the second housing portion is at least partially extended from behind the first housing portion; and

means, disposed in the second housing portion, for displaying information to a user of the mobile communication device,

wherein displaying means is positioned within the second housing portion so that at least a substantial portion of the display means is held behind the first housing portion when the second housing portion is in the retracted position and at least a substantial portion of the displaying means is viewable by a user of the mobile communication device when the second housing portion is in the extended position.

24. The mobile communication device as claimed in claim 23, further comprising means, disposed in the first housing portion, for keying information into the mobile communication device.

25. The mobile communication device as claimed in claim 23, further comprising:

means, disposed in the first housing portion, for viewing at least part of the display means while the second housing portion is in the retracted position,

wherein the displayed information is mapped to the display means so that the information is viewable through the viewing means while the second housing portion is in the retracted position.
