Abstract

A mobile terminal comprises: a body; a first display which is located on one surface of the body, detects a touch input, and outputs a screen; a second display which is located on the other surface of the body, detects a touch input, and outputs a screen; a gyro sensor for detecting movement of the body; and a control unit for controlling the first display and the second display on the basis of the touch input, wherein the control unit outputs a first screen on the first display, when detecting a first touch input on the first display, removes the first screen from the first display, and, when the gyro sensor detects that the locations of the one surface and the other surface of the body are reversed, outputs the first screen on the second display, wherein the mobile terminal may easily implement multitasking by using displays located on both surfaces thereof.

Claims (53)

1. A mobile terminal comprising:

a body;

a flexible display unit having a first display positioned on a first surface of the body and a second display positioned on a second surface of the body opposite the first surface, the flexible display unit surrounding a side surface of the body,

wherein the first display is configured to sense touch inputs;

wherein the second display is configured to sense touch inputs;

a gyro sensor for sensing a movement of the body; and

a controller configured to control the first display and the second display based on the corresponding touch inputs,

wherein the controller is further configured to:

output a first screen image on the first display;

remove the first screen image from the first display when a first touch input is sensed on the first display; and

output the first screen image on the second display when the gyro sensor senses that positions of the first surface and the second surface of the body are reversed,

wherein the first touch input includes a multi-touch-and-drag input where three touch points are dragged in a direction toward the side surface of the body surrounded by the flexible display unit.

2. The mobile terminal of claim 1 , wherein the controller is further configured to deactivate the first display when outputting the first screen image on the second display.

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

not sense a second touch input on the second display in a touch locked state; and

sense the second touch input on the second display in a touch input state,

wherein the controller is further configured to:

not output a virtual key on the second display in the touch locked state; and

switch a state of the second display to the touch input state and output the virtual key on the second display when an unlocking input is sensed.

4. The mobile terminal of claim 1 , wherein the controller is further configured to output the first screen image again on the first display when a second touch input is sensed on the second display after removing the first screen image from the first display.

5. The mobile terminal of claim 1 , wherein the controller is further configured to output the first screen image again on the first display when a second touch input is sensed on the first display after removing the first screen from the first display.

6. The mobile terminal of claim 5 , wherein the controller is further configured to output the first screen image on a floating window superimposed on an existing screen image of the first display.

7. The mobile terminal of claim 1 , wherein the body is configured to expand in a direction of the side surface thereof,

wherein, in the flexible display unit, the first display is expanded and the second display is reduced when the body is expanded.

8. The mobile terminal of claim 7 , wherein the controller is further configured to output an icon corresponding to the first screen image on an expanded portion when the first display is expanded.

9. A mobile terminal comprising:

a body;

a first display positioned on a first surface of the body, wherein the first display is configured to sense touch inputs;

a second display positioned on a second surface of the body opposite the first surface, wherein the second display is configured to sense touch inputs;

a gyro sensor for sensing a movement of the body; and

a controller configured to control the first display and the second display based on the corresponding touch inputs,

wherein the controller is further configured to:

output a first screen image on the first display;

remove the first screen image from the first display when a first touch input is sensed on the first display;

after removing the first screen image from the first display:

output a second screen image on the first display;

remove the second screen image from the first display when the first touch input is again sensed on the first display; and

output the first screen image and the second screen image on the second display to overlap each other when the gyro sensor senses that positions of the first surface and the second surface of the body are reversed.

10. A mobile terminal comprising:

a body;

a first display positioned on a first surface of the body, wherein the first display is configured to sense touch inputs;

a second display positioned on a second surface of the body opposite the first surface, wherein the second display is configured to sense touch inputs;

a gyro sensor for sensing a movement of the body; and

a controller configured to control the first display and the second display based on the corresponding touch inputs,

wherein the controller is further configured to:

output a first screen image on the first display;

remove the first screen image from the first display when a first touch input is sensed on the first display;

after removing the first screen image from the first display:

output a second screen image on the first display;

remove the second screen image from the first display when the first touch input is again sensed on the first display; and

output icons respectively corresponding to the first screen image and the second screen image on the second display when the gyro sensor senses that positions of the first surface and the second surface of the body are reversed;

output the first screen image again on the first display when a second touch input is sensed on the first display after removing the first screen from the first display; and

output the first screen image on a floating window superimposed on an existing screen image of the first display.
