Abstract

A portable electronic device includes a housing with a front frame; a moveable touch-screen display framed by the front frame of the housing, the moveable touch-screen display including a touch-sensitive input surface overlying a display device, the front frame including corners curved outwardly away from the surface of the touchscreen display; a mechanical switch disposed between a back surface of the touchscreen display and a base of the housing; and operational components including a processor within the housing and connected to the touchscreen display. The touchscreen display moves or pivots relative to the housing about a pivot axis in response to application of sufficient force on the touchscreen. This movement or pivoting results in the actuation of the single mechanical switch and the pivot axis depending on the location of application of the force

Claims

1. A portable electronic device, comprising:

a housing including a front frame;

a moveable touchscreen display framed by the front frame of the housing, the touchscreen display including a touch-sensitive input surface overlying a display device, the front frame including corners curved outwardly away from the surface of the touchscreen display;

a mechanical switch disposed between a back surface of the touchscreen display and a base of the housing; and

operational components including a processor within the housing and connected to the touchscreen display,

whereby the touchscreen display moves relative to the base resulting in actuation of the mechanical switch in response to application of sufficient force to the touchscreen display.

2. The portable electronic device according to claim 1, wherein the mechanical switch is further configured to provide a tactile feedback through the touchscreen display upon actuation.

3. The portable electronic device according to claim 1, comprising at least one biasing element to bias the touchscreen display away from the switch mechanism.

4. The portable electronic device according to claim 3, wherein the at least one biasing element comprises foam disposed between the back surface of the touchscreen display and the base of the housing.

5. The portable electronic device according to claim 1, wherein the display device is a liquid crystal display.

6. The portable electronic device according to claim 1, comprising a display support on the back surface of the display device for providing support to the touchscreen display.

7. The portable electronic device according to claim 1, wherein sufficient force applied at any location on the touchscreen display results in movement of the touchscreen display to contact and actuate the mechanical switch.

8. The portable electronic device according to claim 1, wherein the mechanical switch is substantially centered in relation to the touchscreen display.

9. The portable electronic device according to claim 1, wherein an electrical signal is generated in response to actuation of the mechanical switch.

10. The portable electronic device according to claim 9, wherein the electrical signal is received at the processor as a further input in addition to the touchscreen display.
