cause the touch screen to display a first screen corresponding to a first function when it is determined that the touch input is received via the finger of the user;
determine whether the touch pen is a dedicated touch pen that is dedicatedly used for the mobile terminal when it is determined that the touch input was received via the touch pen;
cause the touch screen to display a second screen corresponding to a second function when it is determined that the touch input is received via the dedicated touch pen; and
execute the first function and the second function in a same application or execute the first function via a first application and execute the second function via a second application different from the first application; and
cause the touch screen to display a list including a plurality of contacts corresponding to a plurality of counterparts wherein the touch input is received at a specific contact included in the displayed list;
wherein one of the first function or the second function comprises causing the touch screen to display contact information related to the specific contact and the other of the first function or the second function comprises transmitting data to the specific contact.

2. The mobile terminal of claim 1 , wherein:
the first function comprises an information display function; and
the second function comprises an information input function.

3. The mobile terminal of claim 1 , wherein:
the first function comprises a function that does not involve information input; and
the second function is a touch pen dedicated function.

4. The mobile terminal of claim 1 , wherein the controller is further configured to determine whether the touch input was received via the finger of the user or the touch pen based on at least a touch size, a touch pressure, an electrostatic variation attributed to the received touch input, or a temperature variation attributed to the received touch input.

5. The mobile terminal of claim 1 , further comprising:
a wireless communication unit configured to receive a prescribed signal from the touch pen,
wherein the controller is further configured to determine that the touch input was received via the touch pen based on the received prescribed signal.

6. The mobile terminal of claim 1 , wherein the controller is further configured to:
cease execution of the first function and begin execution of the second function when the touch input is received via the touch pen while the first screen is displayed on the touch screen; and
cease execution of the second function and begin execution of the first function when the touch input is received via the finger of the user while the second screen is displayed on the touch screen.

7. The mobile terminal of claim 1 , wherein:
the controller is further configured to control the touch screen to display a calendar comprising at least one scheduled event, wherein the touch input is received at a specific scheduled event of the displayed at least one scheduled event; and
one of the first function or the second function comprises causing the touch screen to display information related to the specific scheduled event, and
another of the first function or the second function comprises causing the touch screen to display a screen for adding a scheduled event to the calendar for a date corresponding to the specific scheduled event or causing the touch screen to display a screen for editing the specific scheduled event.

8. The mobile terminal of claim 1 , wherein:
the controller is further configured to control the touch screen to display a map, wherein the touch input is received at a specific point of the displayed map;
one of the first function or the second function comprises causing the touch screen to enlarge the map centering on the specific point; and
another of the first function or the second function comprises setting a place corresponding to the specific point as a destination or causing the touch screen to display a screen for inputting a memo related to the specific point.
