Abstract

A key/display assembly includes a first switch and a display module disposed aside the first switch. A touch-sensitive input panel overlies the first switch and the display module, and the touch-sensitive input panel includes a first touch-sensitive region proximate the first switch. The electronic mobile device further includes a first key defined by the first switch and the first touch-sensitive region. As such, the first key is actuated by pressing the first touch-sensitive region to displace the first touch-sensitive region and thereby actuate the first switch.

Claims

1. A key/display, assembly, comprising:

a first switch;

a display module disposed aside the first switch;

a touch-sensitive input panel overlying the first switch and the display module, the touch-sensitive input panel including a first touch-sensitive region proximate the first switch;

a first key having at least one of an invariant text character and an invariant functional character, the first key being further defined by the first switch and the first touch-sensitive region such that the first key is actuated by pressing the first touch-sensitive region to displace the first touch-sensitive region and thereby actuate the first switch.

2. The key/display assembly of claim 1, wherein the first touch-sensitive region is cantilevered past an edge of the display module.

3. The key/display assembly of claim 1, further comprising a compressible gasket disposed between the display module and the touch-sensitive input panel and proximate the edge of the display module.

4. The key/display assembly of claim 1, further comprising a lens overlying the first switch, the display module, and the touch-sensitive input panel, and the lens including a first contact region overlying the first touch-sensitive region;

and

wherein the first key is further defined by the first switch, the first touch-sensitive region, and the first contact region such that the first key is actuated by pressing the first contact region to thereby actuate the first touch-sensitive region and the first switch.

5. The key/display assembly of claim 4, wherein the lens further includes a second contact region defining a second key having at least one of an invariant text character and an invariant functional character.

6. The key/display assembly of claim 5, wherein the lens is continuous between the first contact region and the second contact region.

7. The key/display assembly of claim 5, wherein the touch-sensitive input panel further includes a second touch-sensitive region, and the second key is further defined by the second touch-sensitive region such that the second key is actuated by pressing the second contact region to thereby actuate the second touch-sensitive region.

8. The key/display assembly of claim 7, further comprising a second switch, and wherein the second key is further defined by the second switch such that the second key is actuated by pressing the second contact region to thereby actuate the second touch-sensitive region and the second switch.

9. The key/display assembly of claim 5, wherein the second key is further defined by the first switch such that the second key is actuated by pressing the second contact region to thereby actuate the first switch.

10. The key/display assembly of claim 9, wherein the touch-sensitive input panel is spaced apart from the second contact region such that the second key is actuated by pressing the second contact region without actuating the touch-sensitive input panel.

11. A key/display assembly, comprising:

a first switch;

a display module disposed aside the first switch;

a touch-sensitive input panel overlying the first switch and the display module, the touch-sensitive input panel including a first touch-sensitive region proximate the first switch and cantilevered past an edge of the display module;

a lens overlying the first switch, the display module, and the touch-sensitive input panel, the lens including a first contact region overlying the first touch-sensitive region; and

a first key having at least one of an invariant text character and an invariant functional character, the first key being further defined by the first switch, the first touch-sensitive region, and the first contact region such that the first key is actuated by pressing the first contact region to displace the first touch-sensitive region and thereby actuate the first switch.

12. The key/display assembly of claim 11, wherein the lens further includes a second contact region defining a second key having at least one of an invariant text character and an invariant functional character.

13. The key/display assembly of claim 12, wherein the lens is continuous between the first contact region and the second contact region.

14. The key/display assembly of claim 12, wherein the touch-sensitive input panel further includes a second touch-sensitive region, and the second key is further defined by the second touch-sensitive region such that the second key is actuated by pressing the second contact region to thereby actuate the second touch-sensitive region.

15. The key/display assembly of claim 14, further comprising a second switch, and wherein the second key is further defined by the second switch such that the second key is actuated by pressing the second contact region to thereby actuate the second touch-sensitive region and the second switch.

16. The key/display assembly of claim 12, wherein the second key is further defined by the first switch such that the second key is actuated by pressing the second contact region to thereby actuate the first switch.

17. The key/display assembly of claim 16, wherein the touch-sensitive input panel is spaced apart from the second contact region such that the second key is actuated by pressing the second contact region without actuating the touch-sensitive input panel.
