Mobile terminal and control method therefor

1. A mobile terminal comprising:

a body including a first frame and a second frame;

an extendable display coupled to the body such that a display region viewable at a front of the body is variable according to switching between an enlarged display mode and a reduced display mode, wherein the enlarged display mode corresponds to a mode when the second frame is extended and includes an extended display area of the extendable display that is not visible in the reduced display mode;

an input unit configured to receive user input; and

a controller configured to:

control switching of the extendable display to the enlarged display mode according to receiving a first input via the input unit;

determine a grip method of a user based on a location of the received user input, wherein the switching of the extendable display from the reduced display mode to the enlarged display mode is controlled based on the determined grip method of the user;

cause the extendable display to display content in a left region of the extended display area based on the determined grip method corresponding to a right hand of the user and in response to the switching of the extendable display from the reduced display mode to the enlarged display mode;

execute a first application according to the received first input and to control switching of the extendable display from the reduced display mode to the enlarged display mode based on characteristics of the first application comprising user input frequency,

cause the extendable display to display the first application in a first region of the extended display area based on the user input frequency of the first application exceeding a preset value, and

cause the extendable display to display the first application in a second region of the extended display area based on the user input frequency of the first application not exceeding the preset value.

2. The mobile terminal of claim 1 , wherein the controller is further configured to execute a second application according to receiving a second input comprising a touch drag input, and wherein a display location of the executed second application is determined based on a dragged length of the second input.

3. The mobile terminal of claim 1 , wherein the controller is further configured to cause the extendable display to display an alarm window in the extended display area, and to cause a display of a first mode of a third application corresponding to the alarm window on the extended display area according to receiving a third input for the alarm window.

4. The mobile terminal of claim 3 , wherein the controller is further configured to cause the extendable display to stop displaying the first mode according to receiving a fourth input of a first direction for the first mode, and to cause the extendable display to display a second mode of the third application in the extended display area according to receiving a fifth input of a second direction for the first mode.

5. The mobile terminal of claim 1 ,

wherein the controller is further configured to cause the extendable display to display at least one indicator according to receiving a sixth input, and

wherein the at least one indicator indicates a layout of content displayed during switching of the extendable display to the enlarged display mode.

6. The mobile terminal of claim 1 , wherein the switching of the extendable display to the enlarged display mode is further controlled according to a preset gesture.

7. The mobile terminal of claim 1 ,

wherein the controller is further configured to cause the extendable display to display at least one icon in the extended display area based on switching the extendable display from the reduced display mode to the enlarged display mode, and

wherein the at least one icon indicates an application with a use frequency that exceeds a preset threshold.

8. The mobile terminal of claim 1 , wherein the body includes a first frame and a second frame such that the second frame is extendable or retractable with respect to the first frame.

9. The mobile terminal of claim 8 , wherein the controller is further configured to operate in the enlarged display mode based on an extension of the second frame with respect to the first frame and to operate in the reduced display mode based on a retraction of the second frame with respect to the first frame.

10. The mobile terminal of claim 9 ,

wherein the extendable display comprises a flexible display encompassing the front, a side, and a rear of the body, and

wherein the controller is further configured to control movement of a display portion positioned at the side of the body to the front of the body based on an extension of the second frame with respect to the first frame and to control movement of a display portion positioned at the rear of the body to the front of the body via the side of the body based on the extension of the second frame with respect to the first frame.

11. The mobile terminal of claim 10 , wherein the controller is configured to control movement of a display portion positioned at the front of the body to the side of the body or to the rear of the body via the side of the body based on a retraction of the second frame with respect to the first frame.

12. The mobile terminal of claim 8 , further comprising a driving unit configured to extend or retract the second frame with respect to the first frame.

13. A method of controlling a mobile terminal, the method comprising:

receiving a touch input;

executing an application according to the received touch input;

switching an extendable display to an enlarged display mode from a reduced display mode according to characteristics of a first application, wherein the enlarged display mode corresponds to a mode when a second frame is extended and includes an extended display area of the extendable display that is not visible in the reduced display mode, wherein the second frame is comprised in a body of the mobile terminal along with a first frame;

determining a grip method of a user based on a location of the received touch input, wherein the switching of the extendable display from the reduced display mode to the enlarged display mode is controlled based on the determined grip method of the user;

displaying content in a left region of the extended display area based on the determined grip method corresponding to a right hand of the user and in response to the switching of the extendable display from the reduced display mode to the enlarged display mode;

executing a first application according to the received first input and to control switching of the extendable display from the reduced display mode to the enlarged display mode based on characteristics of the first application comprising user input frequency;

displaying, on the extendable display, the first application in a first region of the extended display area based on the user input frequency of the first application exceeding a preset value; and

displaying, on the extendable display, the first application in a second region of the extended display area based on the user input frequency of the first application not exceeding the preset value.
