User terminal device and displaying method thereof
A user terminal device and a controlling method thereof are provided. The user terminal device includes a display configured to be divided into a first area and a second area which is larger than the first area with reference to a folding line, a cover disposed on a rear side of the display, a detector configured to detect a user interaction on the display and the cover, and a controller configured to, in response to the display being folded along the folding line such that the first area and the second area face each other, control the detector to detect a user interaction through an exposure area, which is an exposed part of the second area, and the cover, and, in response to the display being folded such that the two parts of the cover face with each other with reference to the folding line, control the detector to detect a user interaction through the first area and the second area.
1. A user terminal device comprising:
a flexible display;
a hinge configured to asymmetrically fold together the flexible display into a folded state in which an exposed area that is a portion of the flexible display is viewable; and
one or more processors configured to:
control the flexible display to display a first user interface on the flexible display in response to the flexible display being unfolded from the folded state to an unfolded state in which the flexible display is unfolded; and
control the flexible display to display a second user interface which is different from the first user interface on the exposed area of the flexible display in the folded state.
2. The user terminal device of claim 1 , further comprising:
a cover disposed on a rear side of the flexible display,
wherein in the unfolded state the cover forms a rear side of the user terminal device and the flexible display is a front side of the user terminal device, and
wherein in the folded state the cover forms the rear side of the user terminal device and a portion of the front side of the user terminal device that does not cover the exposed area.
3. The user terminal device of claim 1 , wherein the exposed area is smaller than a half of a size of the flexible display.
4. The user terminal device of claim 1 , wherein the first user interface is a first user interface to unlock a lock screen of the user terminal device and the second user interface is a second user interface to unlock the lock screen of the user terminal device, and
wherein the one or more processors is configured to, in response to the flexible display being unfolded from the folded state to the unfolded state, control the flexible display to display the first user interface to unlock the lock screen of the user terminal device.
5. The user terminal device of claim 1 , wherein the first user interface is a first user interface of a telephone application and the second user interface is a second user interface of the telephone application,
wherein the one or more processors is configured to, in response to receiving a telephone call while the flexible display is in the folded state, control the flexible display to display the second user interface of the telephone application on the exposed area.
6. The user terminal device of claim 5 , wherein the one or more processors is configured to, while the second user interface of the telephone application is displayed on the exposed area, in response to the flexible display being unfolded from the folded state to the unfolded state, control the flexible display to display the first user interface of the telephone application.
7. A method of controlling a user terminal device comprising a flexible display and a hinge configured to asymmetrically fold together the flexible display into a folded state in which an exposed area that is a portion of the flexible display is viewable, the method comprising:
displaying a first user interface on the flexible display in response to the flexible display being unfolded from the folded state to an unfolded state in which the flexible display is unfolded; and
displaying a second user interface which is different from the first user interface on the exposed area of the flexible display in the folded state.
8. The method of claim 7 , wherein the exposed area is smaller than a half of a size of the flexible display.
9. The method of claim 7 , further comprising:
displaying a lock screen on the exposed area of the flexible display in the folded state;
detecting a touch interaction on the exposed area to unlock the lock screen; and
displaying a home screen including a clock on the exposed area based on the touch interaction.
10. The method of claim 7 , wherein the first user interface is a first user interface to unlock a lock screen of the user terminal device and the second user interface is a second user interface to unlock the lock screen of the user terminal device, and
wherein the method further comprises, in response to the flexible display being unfolded from the folded state to the unfolded state, displaying the first user interface to unlock the lock screen of the user terminal device.
11. The method of claim 7 , wherein the first user interface is a first user interface of a telephone application and the second user interface is a second user interface of the telephone application, and
wherein the method further comprises, in response to receiving a telephone call while the flexible display is in the folded state, displaying the second user interface of the telephone application on the exposed area.
12. The method of claim 11 , further comprising:
while the second user interface of the telephone application is displayed on the exposed area, in response to the flexible display being unfolded from the folded state to the unfolded state, displaying the first user interface of the telephone application.
13. The user terminal device of claim 1 , wherein the one or more processors is configured to control the flexible display to display the second user interface based on an event corresponding to an application occurring while the flexible display is in the folded state.
14. The user terminal device of claim 1 , wherein the one or more processors is configured to, while the second user interface is displayed on the exposed area, in response to the flexible display being unfolded from the folded state to the unfolded state, control the flexible display to display the first user interface.
15. A user terminal device comprising:
a flexible display;
a hinge configured to asymmetrically fold together the flexible display into a folded state in which an exposed area that is a portion of the flexible display is viewable; and
one or more processors configured to:
control the flexible display to display a first user interface on the flexible display in response to the flexible display being unfolded from the folded state to an unfolded state in which the flexible display is unfolded; and
control the flexible display to display a second user interface which includes a clock and is different from the first user interface on the exposed area of the flexible display in the folded state.
16. The user terminal device of claim 15 , wherein the one or more processors is configured to:
control the flexible display to display a lock screen on the exposed area of the flexible display in the folded state,
detect a touch interaction on the exposed area to unlock the lock screen, and
control the flexible display to display the second user interface on the exposed area based on the touch interaction.
