execute a function associated with the event when the second state is switched to the first state,

wherein the second region comprises a first portion in which the icon is displayed and a second portion in which screen information that was displayed in the first state is displayed during the second state,

wherein the controller limits input of a control command to the second portion when a touch input is received at the second region during the second state.

2. The mobile terminal of claim 1 , wherein the controller is further configured to:

cause the display to terminate the displaying of the icon when the second state is switched to the first state in response to an external force applied to the second region.

3. The mobile terminal of claim 1 , wherein the controller is further configured to:

cause the display to display a screen corresponding to execution of a function associated with the event on the display when the second state is switched to the first state in response to an external force applied to the second region.

4. The mobile terminal of claim 1 , further comprising:

a wireless communication unit configured to receive information;

wherein the controller is further configured to:

cause the display to display an indicator indicating that the information is received in the first region of the display;

cause the display to display the received information at the second region; and

cause the display to terminate the displaying of the indicator when the second state is switched to the first state in response to an external force applied to the second region.

5. The mobile terminal of claim 4 , wherein the controller is further configured to:

cause the display to maintain the displaying of the indicator after the second state is switched to the first state when a plurality of touch inputs are consecutively received at the second region while the indicator is displayed.

6. The mobile terminal of claim 1 , wherein the icon is displayed in the second region during the second state.

7. The mobile terminal of claim 1 , wherein the controller is further configured to:

cause the display to display guide information in the second region during the second state, wherein the guide information indicates an executable function.

8. The mobile terminal of claim 1 , wherein the first region includes a first part and a second part divided based on the second region; and

wherein the controller is further configured to:

causing the display to visually move information displayed within the second region in response to a touch input to at least one of the first part or the second part of the first region during the second state and while the icon is displayed.

9. The mobile terminal of claim 8 , wherein the controller is further configured to:

cause the display to display an input window in response to a drag input to either one of the first part or the second part of the first region, wherein the input window permits data entry associated with the event.

10. The mobile terminal of claim 9 , wherein the controller is further configured to:

cause the display to display information input via the input window at the second region, wherein the executed function comprises a transmission that includes the displayed information.

11. The mobile terminal of claim 9 , wherein the controller is further configured to:

cause the display to display the input window in an orientation determined by a direction of the drag input; and

cause the display to display information associated with the event in another one of the first part or the second part of the first region when the second state is switched to the first state.

12. The mobile terminal of claim 1 , further comprising:

a wireless communication unit configured to receive a call signal, wherein the event is the receiving of the call signal and the icon indicates that the call signal has not been answered; and

wherein the controller is further configured to:

cause the display to display an indicator at the second region indicating that the call signal is received.

13. The mobile terminal of claim 12 , wherein the controller is further configured to:

cause the display to display a notification icon in the second region indicating that the call signal is released from connection and the call signal is rejected when the second state is switched to the first state.

14. The mobile terminal of claim 12 , wherein the controller is further configured to:

connect the call signal when a first touch input is received at the displayed indicator at the second region; and

cause the display to display screen information for transmitting a reject message for the call signal when a second touch input is received at the displayed indicator.

15. The mobile terminal of claim 1 , wherein the controller is further configured to:

cause the display to switch from the second state to the first state when a plurality of drag inputs are received at the first and second regions in opposing directions and with increasing smaller distances between respective drag inputs; and

cause the display to display the icon for a defined time interval after the second state is switched to the first state.

16. The mobile terminal of claim 15 , wherein when a touch input is received at the displayed icon in a state that a pressure to a plurality of touch positions applied to the first and second regions is maintained, the controller sequentially executes a first function associated with the event and a second function associated with the first function.

17. The mobile terminal of claim 1 , further comprising:

a wireless communication unit configured to transmit and receive wireless signals;

wherein when a call signal is received through the wireless communication unit in a state that the display is in an inactive state, the controller is configured to switch the second region to an active state while the display is in the second state and maintains the first region of the display in an inactive state while the display is in the second state.

18. The mobile terminal of claim 1 , wherein the first region includes a first part and a second part divided based on the second region, and further comprises a sensing unit configured to sense a change to a third state in which part of the second region varies by an external force being applied to another part of the second region in a state that either one of the first part or the second part is placed on a bottom surface and the other part is erected based on the second region as the second region is placed in the second state; and

wherein the controller is further configured to:

control at least one function associated with screen information that has been displayed on the other one of the first part or the second part to be executed in response to the second region being switched from the second state to the third state; and

controls the second region to switch from the third state to the second state subsequent to a predetermined period of time.
