Abstract

A mobile communication device includes a display assembly that may be extended from the housing of the mobile communication device to provide a larger display surface for displaying information to a user of the mobile communication device. The display assembly is movable between a retracted position wherein the display assembly is retracted within a cavity formed in the housing and an extended position wherein the display assembly is extended from the housing. The display assembly includes a display for displaying information to a user of the mobile communication device. A window is provided in the housing for allowing the user to view at least part of the display when the display assembly is retracted within the cavity. Information displayed by the display is mapped to the display so that the information may be viewed through the window while the display assembly is retracted within the cavity.

Claims

1. A mobile communication device, comprising:

a housing having a cavity formed therein, the housing comprising a front face and a side surface;

a display assembly coupled to the housing so that the display assembly is movable between a retracted position wherein the display assembly is at least substantially retracted within the cavity and an extended position wherein the display assembly is extended front the housing, the display assembly including a display for displaying information to a user of the mobile communication device and a frame for mounting the display so that the display is framed by the frame; and

a window disposed in the housing for allowing the user to view at least part of the display when the display assembly is retracted within the cavity, the window being disposed in the front face of the housing and the cavity being formed in the side surface of the housing;

wherein the displayed information is mapped to the display so that the information is viewable through the window while the display assembly is retracted within the cavity, the display assembly pivots about an axis substantially perpendicular to the front face between the retracted position and an intermediate position extended away from the housing, and slides between the intermediate position and the extended position along the side surface in a plane substantially parallel to the front face.

2. The mobile communication device as claimed in claim 1, wherein the cavity comprises an opening and the axis is proximate to a corner of the display assembly adjacent to the opening.

3. The mobile communication device as claimed in claim 1, wherein the window comprises a second display, the second display being semi-transparent so that information displayed by the display is viewable there through.

4. The mobile communication device as claimed in claim 1, further comprising a latching mechanism for latching the display assembly in the retracted position.

5. The mobile communication device as claimed in claim 1, further comprising an extension mechanism for extending the display assembly from the refracted position.

6. The mobile communication device as claimed in claim 1, wherein the displayed information is mapped to an area of the display within the window while the display assembly is in the retracted position, and wherein the displayed information is mapped to the full display while the display assembly is in the extended position.

7. The mobile communication device as claimed in claim 1, further comprising a keypad disposed in the housing adjacent to the window.

8. A mobile communication device, comprising:

a housing having a front face and a side surface, the side surface having a cavity formed therein;

a display assembly coupled to the housing so that the display assembly pivots about an axis substantially perpendicular to the front face between a retracted position wherein the display assembly is retracted within the cavity and an extended position wherein the display assembly is extended from the housing, the display assembly including a display for displaying information to a user of the mobile communication device and a frame for mounting the display so that the display is framed by the frame; and

a window disposed in the front face for allowing the user to view at least part of the display when the display assembly is retracted within the cavity, the window comprises a second display, second display being semi-transparent so that information displayed by the display is viewable there through,

wherein the displayed information is mapped to the display so that the information is viewable through the window while the display assembly is retracted within the cavity, the display assembly pivots about an axis substantially perpendicular to the front face between the retracted position and an intermediate position extended away from the housing, and slides between the intermediate position and the extended position along the side surface in a plane substantially parallel to the front face.

9. The mobile communication device as claimed in claim 8, wherein the cavity comprises an opening and the axis is proximate to a corner of the display assembly adjacent to the opening.

10. The mobile communication device as claimed in claim 8, further comprising a latching mechanism for latching the display assembly in the retracted position.

11. The mobile communication device as claimed in claim 8, further comprising an extension mechanism for extending the display assembly from the retracted position.

12. The mobile communication device as claimed in claim 8, wherein the displayed information is mapped to an area of the display within the window while the display assembly is in the retracted position, and wherein the displayed information is mapped to the full display while the display assembly is in the extended position.

13. The mobile communication device as claimed in claim 8, further comprising a keypad disposed in the front face adjacent to the window.

14. A mobile communication device, comprising:

a housing having a front face and a side surface, the side surface having a cavity formed therein;

a display assembly coupled to the housing so that the display assembly is movable between a retracted position wherein the display assembly is retracted within the cavity and an extended position wherein the display assembly is extended from the housing, the display assembly including a frame mounting a display for displaying information to a user of the mobile communication device; and

a window disposed in the front face for allowing the user to view at least part of the display when the display assembly is retracted within the cavity,

wherein the display assembly pivots about an axis substantially perpendicular to the front face between the retracted position and an intermediate position and slides between the intermediate position and the extended position along the side surface in a plane substantially parallel to the front face.

15. The mobile communication device as claimed in claim 14, wherein the cavity comprises an opening and the axis is proximate to a corner of the display assembly adjacent to the opening.

16. The mobile communication device 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 there through.

17. The mobile communication device as claimed in claim 14, further comprising a latching mechanism for latching die display assembly in the retracted position.

18. The mobile communication device as claimed in claim 14, further comprising an extension mechanism for extending the display assembly from the refracted position.

19. The mobile communication device as claimed in claim 14, wherein the displayed information is mapped to an area of the display within the window while the display assembly is in the retracted position and wherein the displayed information is mapped to the full display while the display assembly is in the extended position.

20. The mobile communication device as claimed in claim 14, further comprising a keypad disposed in the front face adjacent to the window.
