3. The capacitive TSP of claim 1 , wherein each one of the respective terminal vertical edges and terminal horizontal edges has a zigzag shape.

4. The capacitive TSP of claim 1 , further comprising:

a control unit configured to receive graphical user interface (GUI) display location data and generate a control signal to activate/deactivate at least one of the plurality of TSP sections in response to the GUI display location data.

5. The capacitive TSP of claim 4 , further comprising:

a power supply unit configured to independently apply power to each one of the plurality of TSP sections in response to the control signal.

6. The capacitive TSP of claim 5 , wherein the control signal comprises a first control signal selecting the at least one of the plurality of TSP sections, and a second control signal enabling the power supply unit to apply power to the at least one of the plurality of TSP sections.

7. The capacitive TSP of claim 1 , further comprising:

a first control unit configured to receive graphical user interface (GUI) display location data and generate a first control signal to activate/deactivate the first TSP section in response to the GUI display location data;

a second control unit configured to receive the GUI display location data and generate a second control signal to activate/deactivate the second TSP section in response to the GUI display location data;

a third control unit configured to receive the GUI display location data and generate a third control signal to activate/deactivate the third TSP section in response to the GUI display location data; and

a fourth control unit configured to receive the GUI display location data and generate a fourth control signal to activate/deactivate the fourth TSP section in response to the GUI display location data.

8. The capacitive TSP of claim 7 , further comprising:

a power supply unit configured to independently apply power to each one of the first, second, third and fourth TSP sections in response to the first, second, third and fourth control signals, respectively.

9. A method of receiving user-defined touch data in a system comprising a capacitive touch screen panel (TSP) incorporating a plurality of TSP sections assembled in a planar arrangement to provide a unitary user interface area having a first area, the method comprising:

receiving input data defining a first region of permissible user touch input having a second area within the unitary user interface area, wherein the second area is less than the first area; and

activating a first TSP section among the plurality of TSP sections in response to the definition of the first region of permissible user touch input while a second TSP section among the plurality of TSP sections is deactivated.

10. The method of claim 9 , wherein activating the first TSP section comprises applying power to the first TSP section.

11. The method of claim 9 , wherein the first region of permissible user touch input displays at least in part a first Graphical User Interface (GUI).

12. The method of claim 11 , further comprising:

receiving user touch data via the first GUI that defines a second region of permissible user touch input within the unitary user interface area; and

activating the second TSP section in response to the defined second region of permissible user touch input.

13. The method of claim 12 , wherein the second region of permissible user touch input displays at least in part a second GUI, such that the second GUI is displayed within at least some portion of the first and second TSP sections.

14. The method of claim 13 , further comprising:

receiving additional user touch data via the second GUI and defining a third region of permissible user touch input within the unitary user interface area; and

deactivating at least one of the first TSP section and the second TSP section in response to the defined third region of permissible user touch input.

15. The method of claim 14 , wherein the third region of permissible user touch input displays a third GUI wholly within only one of the first and second TSP sections.

16. The method of claim 11 , wherein the first GUI includes at least one of a virtual keyboard, a command menu, a file list, and a number-pad.

17. The method of claim 9 , wherein the unitary user interface area has a first width and each one of the plurality of TSP sections has a width less than the first width.
