Abstract

Provided is a mobile electronic device including: a display unit that is formed to be so flexible that at least one portion of the display unit is capable of being bent, and that is configured from a first segment of which one portion and the other portion are brought into contact with each other when the display unit is bent, and a second segment that is different from the first segment and extends from the first segment; a sensing unit that detects a shape change in the first segment due to an external force; and a controller that controls information that is output to the second segment, based on the shape change.

First claim

What is claimed is:

1. A mobile electronic device comprising: a flexible display comprising:
a touch panel configured to be a capacitive type;
a bendable portion;
a first display area;
a second display area; and
a third display area coupled to one end of the second display area,
wherein the display is configured such that:
the first display area and the second display area are configured to be in contact with or close proximity to each other when the display is bent via the bendable portion and comprise a first segment; and
a first size of the first segment and a second size of a second segment comprising a third display area are variable based on how the display is bent,
the first size increasing when the second size decreases and the first size decreasing when the second size increases; and
a controller configured to:
cause the third display area to display a plurality of icons;
detect an area of which the first display area and the second display area are brought into contact with each other via the touch panel;
detect a twist of the first display area with respect to the second display area in a leftward or rightward direction based on an overlapped extent of the detected area; and
select an icon among the plurality of icons when the first display area in a twisted state returns to its original state within a predetermined amount of time when an external force for twisting the first display area lapses,
wherein the selected icon varies based on whether the detected twist is in the leftward direction or rightward direction.

2. The electronic device of claim 1 , wherein the selected icon displayed on the third display area is for informing a user to an event related to an application.

3. The electronic device of claim 2 , wherein:
the display is further configured such that the first size is decreased and the second size is increased from a base level to a first level when a first sliding gesture is applied to the first display area; and
the controller is further configured to cause the display to display first information relating to a first event on the third display area with the second size increased to the first level, the first event associated with the application.

4. The electronic device of claim 3 , wherein the controller is further configured to cause the display to display a different amount of information on the third display area based on the second size that is decreased or increased.

5. The electronic device of claim 4 , wherein:
the display is further configured such that the first size is further decreased and the second size is further increased to a second level when a second sliding gesture is applied to the first display area; and
the controller is further configured to cause the display to display second information in addition to the first information on the third display area with the second size increased to the second level, the second information relating to a second event.

6. The electronic device of claim 3 , wherein:
the third display area is partitioned into a first portion and a second portion;
the icon is displayed in the first portion; and
the first information is displayed in the second portion.

7. The electronic device of claim 3 , wherein the controller is further configured to cause the display to display an execution screen of the application on the third display area when the second size is increased to a level that is equal to or greater than a reference size.

8. The electronic device of claim 3 , wherein: the display is further configured such that the second size is decreased to the base level when a third sliding gesture is applied to the first display area after the first sliding gesture; and the controller is further configured to cause the display to no longer display the first information on the third display area with the second size decreased to the base level.

9. The electronic device of claim 1 , wherein:
the information is a call receiving screen displayed in response to a call received from another device; and
the controller is further configured to accept or refuse the call based on the direction of the inclination detected while the call receiving screen is displayed on the third display area, the call accepted when the direction is a first direction and the call refused when the direction is a second direction that is substantially opposite of the first direction.

10. The electronic device of claim 1 , wherein: the plurality of icons displayed on the third display area are for alerting a user to multiple events related to a plurality of applications, each of the plurality of icons informing an event related to a corresponding one of the plurality of applications; and the controller is further configured to cause the display to selectively display information relating to at least one of the multiple events on the third display area based on the direction of the selected icon.

11. The electronic device of claim 1 , further comprising a wireless communication unit configured to receive a signal, wherein the controller is further configured to cause the display to display at least a portion of information received via the wireless communication unit on the third display area.

12. The electronic device of claim 1 , further comprising a sensing unit configured to sense inclination of the first display area with respect to the second display area in a leftward or a rightward direction, the inclination caused by an external force applied to the first display area,
wherein the controller is further configured to:
detect the inclination via the sensing unit while the bendable portion is in a fixed state in which the display is bent; and
execute a first function or a second function with respect to information displayed on the third display area based on a direction of the detected inclination, and

wherein the inclination is detected in a state where the first display area and the second display area, which are consisting of one surface, are facing each other.

13. A method of controlling a mobile electronic device comprising a flexible display, wherein:
the flexible display comprises a touch panel configured to be a capacitive type;
a bendable portion;
a first display area;
a second display area; and
a third display area connected to one end of the second display area;
the display is configured such that:
the first display area and the second display area are configured to be in contact with or close proximity to each other when the display is bent via the bendable portion and comprise a first segment; and
a first size of the first segment and a second size of a second segment comprising the third display area are variable based on how the display is bent,
the first size increasing when the second size decreases and the first size decreasing when the second size increases; and the method comprises:
displaying a plurality of icons on the third display area;
detecting an area of which the first display area and the second display area are brought into contact with each other via the touch panel;
detecting a twist of the first display area with respect to the second display area in a leftward or rightward direction based on an overlapped extent of the detected area; and
selecting an icon among the plurality of icons when the first display area in a twisted state returns to its original state, when an external force for twisting the first display area lapses,
wherein the selected icon varies based on whether the detected twist is in the leftward direction or rightward direction.
