Abstract

A display apparatus is provided. The display apparatus includes a flexible display configured to display an image, a driver configured to change a screen size of the flexible display, and a processor configured to control the driver to display an image corresponding to a content, at a screen size corresponding to a size of a content to be displayed in the flexible display.

Claims

1. A display apparatus comprising:

a flexible display configured to display an image;

a driver configured to change a screen size of the flexible display; and

a processor configured to control the driver to display an image corresponding to a content to be displayed on the flexible display, at a screen size corresponding to a size of the content.

2. The apparatus as claimed in claim 1, wherein the processor is configured to determine a screen ratio of the content and controls the driver such that the flexible display has a screen size corresponding to the determined screen ratio.

3. The apparatus as claimed in claim 1, wherein the flexible display has a display area which is flat and is rollable towards one side, and

wherein the driver is configured to vary a screen size of the flexible display by rolling or unrolling a partial area of the display area.

4. The apparatus as claimed in claim 3, wherein the driver is configured to vary a width of the flexible display by rolling or unrolling the display area in a transverse direction of the display apparatus.

5. The apparatus as claimed in claim 1, wherein the processor is configured to, in response to a particular event occurring, control the driver and the flexible display to display a user interface (UI) element corresponding to the particular event, at a screen size corresponding to the UI element.

6. The apparatus as claimed in claim 5, wherein the particular event is a command to drive a smart television (TV) function, and

wherein the processor is configured to:

control a channel list to be displayed at a preset first screen size, and

in response to any one channel from among the displayed channel list being selected, control a content corresponding to the selected channel to be displayed at a second screen size which is larger than the first screen size.

7. The apparatus as claimed in claim 5, wherein the particular event is a reception of a notification message regarding an event or state change that occurred in a device connected to the display apparatus within a home network, and

wherein the processor is configured to:

control the notification message to be displayed at a predetermined first screen size, and

in response to the notification message being selected, control device information corresponding to the notification message to be displayed at a second screen size which is larger than the first screen size.

8. The apparatus as claimed in claim 1, wherein the processor is configured to, while changing a screen size of the flexible display, change a size of an image corresponding to the content and display the image.

9. The apparatus as claimed in claim 1, wherein the processor is configured to, while changing a screen size of the flexible display, fix a size of an image corresponding to the content and display the image.

10. The apparatus as claimed in claim 1, wherein the processor is configured to, while changing a screen size of the flexible display, control an image corresponding to the content not to be displayed.

11. The apparatus as claimed in claim 1, wherein the processor is configured to, while changing a screen size of the flexible display, display a UI element unrelated to the content.

12. The apparatus as claimed in claim 1, further comprising:

a communication interface configured to receive screen size information from an external apparatus,

wherein the processor is configured to controls the driver to display the image at a screen size corresponding to the received size information.

13. A displaying method of a display apparatus including a flexible display, the displaying method comprising:

determining a screen size of the flexible display corresponding to a size of a content to be displayed in the flexible display;

changing a screen size of the flexible display to the determined screen size; and

displaying an image corresponding to the content using the flexible display.

14. The method as claimed in claim 13, wherein the determining comprises determining a screen ratio of the content, and determining a screen size corresponding to the determined screen ratio.

15. The method as claimed in claim 13, wherein the changing comprises rolling or unrolling a display area, which is flat in a transverse direction, of the display apparatus and changing a width of the flexible display.

16. The method as claimed in claim 13, wherein the determining comprises, in response to a particular event occurring, determining a screen size corresponding to a screen ratio of a user interface (UI) element corresponding to the particular event, and

wherein the displaying comprises displaying the UI element.

17. The method as claimed in claim 13, wherein the displaying comprises, while changing a screen size of the flexible display, changing a size of an image corresponding to the content and displaying the image.

18. The method as claimed in claim 13, wherein the displaying comprises, while changing a screen size of the flexible display, fixing a size of an image corresponding to the content and displaying the image.

19. The method as claimed in claim 13, further comprising:

detecting a user gesture; and

changing the screen size of the flexible display in response to the detected user gesture.

20. The method as claimed in claim 13, further comprising:

detecting movement of a remote controller; and

changing the screen size of the flexible display in response to the detected movement.
