1. A mobile terminal comprising:
a body having a variable size;
a flexible display including a first display located on a front face of the body and a second display located on a rear face of the body;
a driving unit configured to change the size of the body and a size of the first display;
a sensing unit configured to sense an input signal; and
a controller configured to:
in response to the input signal having a value equal to or greater than a threshold value, control the driving unit to change the size of the body and the size of the first display,
wherein a size of the second display is correspondingly reduced as the size of the first display increases,
wherein a portion of the flexible display wraps around one side of the body,
wherein the sensing unit includes a touch sensor embedded in the flexible display, and
wherein the threshold value is determined based on a total contact area of a user with the touch sensor when the user inputs a touch drag on the first display.
 
18. A method of controlling a size of a mobile terminal, the method comprising:
in response to sensing, via a sensing unit of the mobile terminal, a touch input on a first display having a value equal to or greater than a threshold value, increasing both a variable size of a body of the mobile terminal and a size of the first display located on a front face of the body while correspondingly decreasing a size of a second display located on a rear face of the body; and
displaying, on the first display, a selection menu for selecting one of a plurality of sizes when the value of the touch input is equal to or greater than the threshold value,
wherein a region of the first display remains fixed.
 
20. A mobile terminal comprising:
a body having a variable size;
a flexible display including a first display located on a front face of the body and a second display located on a rear face of the body;
a driving unit configured to change the size of the body and a size of the first display;
a sensing unit configured to sense an input signal; and
a controller configured to:
in response to the input signal having a value equal to or greater than a threshold value, control the driving unit to change the size of the body and the size of the first display,
wherein a size of the second display is correspondingly reduced as the size of the first display increases,
wherein a portion of the flexible display wraps around one side of the body,
wherein the sensing unit includes a touch sensor embedded in the flexible display,
wherein the threshold value is determined based on a touch area on the first display touched by a user, and
wherein the controller is further configured to:
in response to the sensing unit sensing a plurality of touch signals simultaneously on the first display, add areas based on the plurality of touch signals to generate a sum and compare the sum with the threshold value.
