Abstract

An image display apparatus including a rollable display; a driving unit configured to change a size of the rollable display; an interface configured to receive a signal from a remote controller; and a controller configured to in response to an image display input, control the driving unit to unroll the rollable display, and display a first video, corresponding to a video to be displayed on the unrolled display, on a display of the remote controller and without displaying the video on the rollable display during the unrolling of the rollable display.

First claim

What is claimed is:

1. An image display apparatus, comprising:
a rollable display;
a driving unit configured to change a size of the rollable display;
an audio output unit;
an interface configured to receive a signal from a remote controller; and
a controller configured to:
in response to an image display input, control the driving unit to unroll the rollable display, and
display a first video, corresponding to a video to be displayed on the unrolled display, on a display of the remote controller and without displaying the video on the rollable display during the unrolling of the rollable display,
wherein the controller controls the first video to be displayed on the display of the remote controller during the unrolling of the rollable display, and outputs sound, corresponding to the first video, through the audio output unit, or controls sound, corresponding to the first video, to be output through a sound output module of the remote controller.

2. The image display apparatus of claim 1 , wherein the interface transmits video information to the remote controller so that the first video is displayed on the display of the remote controller during the unrolling of the rollable display.

3. The image display apparatus of claim 1 , wherein when the rollable display is unrolled such that a height of the rollable display is a first height, the controller displays the video on the rollable display.

4. The image display apparatus of claim 3 , wherein the controller controls the drive unit to unroll the rollable display from a rolled position in which the rollable display is rolled within a casing so as not to be exposed outside the casing.

5. The image display apparatus of claim 3 , wherein:
during the unrolling of the rollable display, and when the height of the rollable display is a second height which is lower than the first height, the controller controls the first video to be displayed on the display of the remote controller; and
during the unrolling of the rollable display, and when the height of the rollable display is a third height which is higher than the second height, the controller controls the first video and a thumbnail list including a plurality of thumbnail images to be displayed on the display of the remote controller.

6. The image display apparatus of claim 5 , wherein when the rollable display is unrolled such that the height of the rollable display reaches the first height, the controller displays the video on the rollable display, and controls only the thumbnail list to be displayed on the display of the remote controller.

7. The image display apparatus of claim 1 ,
wherein when the rollable display is unrolled such that a height of the rollable display is a first height, the controller displays the video on the rollable display, and controls the sound, corresponding to the first video, to be output through the audio output unit.

8. The image display apparatus of claim 7 , wherein when the rollable display is unrolled such that the height of the rollable display is the first height, the controller controls the first video not to be displayed on the display of the remote controller, and controls the sound, corresponding to the first video, not to be output through the sound output module of the remote controller.

9. The image display apparatus of claim 1 , wherein the controller controls the first video and a channel list to be displayed on the display of the remote controller, and
wherein after any one channel is selected from the channel list displayed on the display of the remote controller, and when the rollable display is unrolled such that a height of the rollable display reaches a first height, the controller displays a broadcast video, corresponding to the selected channel, on the rollable display instead of the video to be displayed.

10. The image display apparatus of claim 1 , wherein the controller controls an application list including a plurality of application items to be displayed on the display of the remote controller during the unrolling of the rollable display.

11. The image display apparatus of claim 10 , wherein after a first application item is selected from the application list displayed on the display of the remote controller, and when the rollable display is unrolled such that a height of the rollable display reaches a first height, the controller displays an application screen, corresponding to the selected first application item, on the rollable display instead of the video to be displayed.

12. The image display apparatus of claim 1 , wherein during the unrolling of the rollable display, the controller controls a broadcast video to be displayed on the display of the remote controller, and displays an application list including a plurality of application items on the rollable display.

13. The image display apparatus of claim 12 , wherein when the rollable display is unrolled such that a height of the rollable display reaches a first height, the controller displays the broadcast video and the application list on the rollable display.

14. The image display apparatus of claim 13 , wherein based on a pointing signal from the remote controller, the controller displays a pointer on the broadcast video or the application list.

15. The image display apparatus of claim 1 , wherein after any one of recommended content information or preferred content information, which are displayed on the display of the remote controller, is selected, and when the rollable display is unrolled such that a height of the rollable display reaches a first height, the controller displays a video, corresponding to the selected content, on the rollable display.

16. The image display apparatus of claim 15 , wherein in response to the selected content being a music content, and after any one of the recommended content information or the preferred content information is selected and the rollable display is fully unrolled, the controller displays information on the music content on the rollable display.

17. The image display apparatus of claim 1 , wherein, when the rollable display is unrolled such that a height of the rollable display reaches a first height, the controller displays a broadcast video on the rollable display, and controls a menu, including a channel control item and a volume control item, to be displayed on the display of the remote controller.

18. The image display apparatus of claim 1 , wherein the drive unit is included in a casing and comprises:
a roller on which the rollable display is wound; and
a motor to rotate the roller, and
wherein the controller controls the drive unit to roll the rollable display on the roller via the motor such that the rollable display is not exposed outside of the casing in a standby mode.
