Abstract

A display device includes a main body configured to have a display module to which a user interface is output, a bending module located at a center of a back surface of the main body, and a controller. The controller controls the bending module to change a curvature of the display module to any one of a flat mode in which the display module is flat, a first bending mode in which the display module has a first curvature, and a second bending mode in which the display module has a second curvature, wherein the second curvature is a maximum curvature of the display module. Then, the controller changes at least one of a size and a position of a display region to which the user interface is output, according to whether a mode is the flat mode, the first bending mode, or the second bending mode.

First claim

What is claimed is:

1. A display device comprising:
a main body configured to have a display module to which a user interface is output;
a bending module located at a center of a back surface of the main body; and
a controller,
wherein
the controller is configured to:
control the bending module to change a curvature of the display module to any one of a flat mode in which the display module is flat, a first bending mode in which the display module has a first curvature, or a second bending mode in which the display module has a second curvature, wherein the second curvature is a maximum curvature of the display module, and
change at least one of a size or a position of a display region to which the user interface is output, according to whether the curvature of the display module is in the flat mode, the first bending mode, or the second bending mode, and
wherein:
based on the curvature of the display module being in the flat mode, the controller outputs the user interface to a first region of the display module;
based on the curvature of the display module being in the second bending mode, the controller outputs the user interface to a second region of the display module that is smaller in size than the first region;
the user interface includes a plurality of items;
the controller is further configured to:
output the plurality of items spaced apart from each other by a first spacing to the first region in the flat mode;
output the plurality of items spaced apart from each other by a second spacing to the second region in the first bending mode; and
output the plurality of items spaced apart from each other by a third spacing to a third region of the display module in the second bending mode, the third region being smaller in size than the second region; and
the second spacing is smaller in distance than the first spacing, and the third spacing is smaller in distance than the second spacing.

2. The display device according to claim 1 , wherein:
the controller is further configured to adjust a size of the user interface based on sizes of the first region and the second region.

3. The display device according to claim 1 , wherein:
when the plurality of items is output to the second region, the controller enables the plurality of items to be output in a centralized arrangement format.

4. The display device according to claim 1 , wherein:
when the plurality of items is output to the second region, the controller enables the plurality of items to be output in a fan-shaped arrangement format.

5. The display device according to claim 4 , wherein the controller is further configured to:
receive a second control signal from a remote controller; and
select a first item from among the plurality of items based on the received second control signal.

6. The display device according to claim 5 , wherein the controller is further configured to:
upon receiving a selection signal for selecting an UP button from the remote controller, select a second item from among the plurality of items arranged in the fan-shaped arrangement format,
wherein the second item is located at a most central position or an uppermost position of the fan-shaped arrangement format.

7. The display device according to claim 1 , further comprising:
one pair of links having one end coupled to the bending module, and extending in a horizontal direction; and
a link bracket disposed at left and right ends of the main body and connected to the other end of the links,
wherein the bending module includes:
a guide shaft extending from the back surface of the main body; and
a movable block inserted into the guide shaft and configured to move forward and backward,
wherein, when the movable block moves forward and backward along the guide shaft, an angle between the links is changed and the curvature of the display module is also changed.

8. The display device according to claim 1 , wherein the first curvature value is settable by the user in units of 100R.

9. The display device according to claim 1 , wherein the controller is further configured to:
receive a control signal from a remote controller operable by a user; and
based on the received control signal, control the bending module to change the curvature of the display module to a first curvature value that is set by the user and that is different from all preset curvature values.

10. A method for controlling a display device which includes a main body having a display module to which an image is output, and a bending module located at a center of a back surface of the main body, the method comprising:
outputting a user interface image through the display module of the display device;
controlling the bending module to change a curvature of the display module to any one of a flat mode in which the display module is flat, a first bending mode in which the display module has a first curvature, or a second bending mode in which the display module has a second curvature, wherein the second curvature is a maximum curvature of the display module; and
changing at least one of a size or a position of a display region to which the user interface is output, according to whether the curvature of the display module is in the flat mode, the first bending mode, or the second bending mode,
wherein:
based on the curvature of the display module being in the flat mode, the controller outputs the user interface image to a first region of the display module;
based on the curvature of the display module being in the second bending mode, the controller outputs the user interface image to a second region of the display module that is smaller in size than the first region;
the user interface includes a plurality of items;
the method further comprises:
outputting the plurality of items spaced apart from each other by a first spacing to the first region in the flat mode;
outputting the plurality of items spaced apart from each other by a second spacing to the second region in the first bending mode; and
outputting the plurality of items spaced apart from each other by a third spacing to a third region of the display module in the second bending mode, the third region being smaller in size than the second region; and
the second spacing is smaller in distance than the first spacing, and the third spacing is smaller in distance than the second spacing.
