Abstract

A display device including a display unit configured to output a base image; a curvature sensing unit configured to sense one of a forward folded state and a reverse folded state of the display unit; and an interface control unit configured to generate an interface image. The interface image may include a forward folded interface image corresponding to the forward folded state of the display unit, or a reverse folded interface image corresponding to the reverse folded state of the display unit. The interface control unit is configured to overlay the interface image on a base image and output the overlaid image.

Claims

1. A display device comprising:

a display unit configured to display a base image;

a curvature sensing unit configured to sense one of a forward folded state and a reverse folded state of the display unit; and

an interface control unit configured to control the display unit to overlay the base image with;

a forward folded interface image when the forward folded state is detected; and

a reverse folded interface image when the reverse folded state of the display unit is detected.

2. The device of claim 1, wherein the display unit comprises a first display unit and a second display unit that are pivotably connected at a position where forward folding and reverse folding movements occur.

3. The device of claim 2, further comprising a touch sensing unit configured to detect a selection one of the forward folded interface image and the reverse folded interface image.

4. The device of claim 3, further comprising an image control unit configured to generate image data corresponding to one of the forward folded interface image and the reverse folded interface image, and to output the image data to the display unit.

5. The device of claim 4, wherein the forward folded interface image comprises a split interface configured to split the base image, and a maintaining interface configured to maintain the base image.

6. The device of claim 5, wherein the split interface comprises:

first image data displayed by the first display unit;

second image data displayed by the second display unit, the second image data being different from the first image data; and

the first image data comprises a version of the base image resized for display on the first display unit.

7. The device of claim 6, wherein:

when the split interface is dragged toward the first display unit, the resized base image is displayed by the first display unit; and

when the split interface is dragged toward the second display unit, the resized base image is displayed by the second display unit.

8. The device of claim 6, wherein when the touch sensing unit senses an input of a user selecting the maintaining interface, the first display unit and the second display unit display the base image.

9. The device of claim 4, wherein the base image comprises a first base image output to the first display unit and a second base image output to the second display unit.

10. The device of claim 9, wherein the reverse folded interface image comprises at least one of:

a switching interface configured to switch positions of the first base image and the second base image;

a first image interface configured to resize the first base image to fit both the first display unit and the second display unit; and

a second image interface configured to resize the second base image to the size of both the first display unit and the second display unit.

11. The device of claim 10, wherein, when the touch sensing unit senses an input of a user selecting the switching interface, the second base image is resized and output to the first display unit, and the first base image is resized and output to the second display unit.

12. The device of claim 10, wherein when the touch sensing unit detects an input of a user selecting the first image interface, an enlarged first base image is output to both the first display unit and the second display unit together.

13. The device of claim 10, wherein when the touch sensing unit detects an input of a user selecting the second image interface, an enlarged second base image is output to both the first display unit and the second display unit together.

14. A display method for a display device, the method comprising:

outputting a base image on a display unit, the display unit comprising a first display unit and a second display unit that are pivotably connected at a position where forward folding and reverse folding movements occur;

sensing one of a forward folded state and a reverse folded state of the display unit;

generating an interface image when one of the forward folded state and reverse folded state of the display unit is sensed; and

overlaying the interface image on the base image, and outputting the overlaid image.

15. The method of claim 14, further comprising:

sensing an input of a user selecting the interface image;

generating image data corresponding to the sensed input of the user; and

outputting the image data on the display unit.

16. The method of claim 15, wherein, when the forward folded state is sensed, the outputting of the interface image comprises outputting at least one of a split interface configured to split the base image, and a maintaining interface configured to maintain the base image.

17. The method of claim 15, wherein the outputting of the base image comprises outputting a base image comprising a first base image output to the first display unit and a second base image output to the second display unit.

18. The method of claim 17, wherein, when one of the forwarded folded state or the reverse folded state is sensed, the outputting of the interface comprises outputting at least one of:

a switching interface configured to switch positions of the first base image and the second base image;

a first image interface configured to enlarge the first base image to fit the first display unit or the second display unit, and to output the enlarged image; and

a second image interface configured to enlarge the second base image to fit the size of the first display unit or the second display unit, and to output the enlarged image.
