Abstract

The present invention relates to a mobile device having a backpanel touchpad, and more particularly, to a technique for enabling cursor movements and execution instructions on a frontpanel display screen to be inputted through a touchpad positioned at a backpanel of a mobile device. Accordingly, a touchpad is disposed on a back side of a mobile device, so that the mobile device can be controlled through a contact point at which a user'"'"'s finger is naturally positioned when a user holds the mobile device with a user'"'"'s hand. Further, a backpanel touchpad is operated, so that a display screen is not covered with the user'"'"'s finger.

Claims

1. A mobile device, comprising:

a frontpanel display disposed on the front side of said mobile device for providing display on a screen;

a backpanel touchpad disposed on the back side of said mobile device, said backpanel touchpad receiving cursor movements and execution instructions through touch operations; and

a controller for displaying a cursor on said frontpanel display whose cursor operations are provided on said backpanel touchpad, wherein said controller receives an execution instruction on said backpanel touchpad so as to process said execution instruction corresponding to the cursor position of said execution instruction on said frontpanel display.

2. The mobile device as claimed in claim 1, wherein said backpanel touchpad is disposed at both ends of the back side.

3. A mobile device, comprising:

a frontpanel touchscreen disposed on the front side of said mobile device, the frontpanel touchscreen having image display function and touchpad function;

a backpanel touchscreen disposed on the back side of said mobile device, the backpanel touchscreen having image display function and touchpad function; and

a controller for displaying a cursor on said frontpanel touchscreen whose cursor operations are provided on said backpanel t touchscreen and for receiving an execution instruction on said backpanel touchscreen so as to process said execution instruction corresponding to the cursor position of said execution instruction on said frontpanel touchscreen, said controller for displaying a cursor on said backpanel touchscreen whose cursor operations are provided on said frontpanel touchscreen and for receiving an execution instruction on said frontpanel touchscreen so as to process said execution instruction corresponding to the cursor position of said execution instruction on said backpanel touchscreen.

4. The mobile device as claimed in claim 3, wherein said controller alternately switches said functions of said frontpanel and backpanel touchscreens, wherein when said controller inactivates the touchpad function with activating the display function for one touchscreen, said controller activates the touchpad function with inactivating the display function for the other touchscreen.
