Abstract

Disclosed are a multimedia device including a flexible display and controlling method thereof. The present invention includes a guide bar, a flexible display configured to be rolled up on an outer circumference of the guide bar, the flexible display having a first region rolled up on the outer circumference of the guide bar and a second region not rolled up on the outer circumference of the guide bar, a receiving unit configured to receive a content and metadata corresponding to the content from a source device, and a control unit adjusting a vertical width of the second region of the flexible display in accordance with a preset condition.

Claims

1. A multimedia device comprising:

a guide bar;

a flexible display configured to be rolled up on an outer circumference of the guide bar, the flexible display having a first region rolled up on the outer circumference of the guide bar and a second region not rolled up on the outer circumference of the guide bar;

a receiving unit configured to receive a content and metadata corresponding to the content from a source device; and

a control unit adjusting a vertical width of the second region of the flexible display in accordance with a preset condition.

2. The multimedia device of claim 1, wherein the control unit extracts an aspect ratio information from the received metadata and determines the vertical width of the second region of the flexible display in accordance with the extracted aspect ratio information.

3. The multimedia device of claim 1, further comprising a storage unit configured to store a function or lookup table for determining the vertical width of the second region in accordance with an aspect ratio of a screen within the second region of the flexible display, wherein the control unit detects the function or a value in the lookup table by accessing the storage unit and then determines the vertical width of the second region of the flexible display using the detected function or value in the lookup table.

4. The multimedia device of claim 1, further comprising a user interface unit configured to receive a command signal for selecting an aspect ratio of a screen within the second region of the flexible display, wherein the control unit determines a vertical width of the second region of the flexible display in accordance with the received command signal.

5. The multimedia device of claim 1, wherein the guide bar is installed to enable a height adjustment.

6. The multimedia device of claim 5, further comprising a sensor configured to sense a user'"'"'s eye, wherein the control unit adjusts a height of the guide bar to enable the sensor and the user'"'"'s eye to be situated in parallel with each other on a same level.

7. The multimedia device of claim 1, wherein a screen with the second region of the flexible display comprises at least one of a first partitioned region and a second partitioned region.

8. The multimedia device of claim 7, wherein if a caption data is included in the received metadata, the control unit controls a video data in the received content and the caption data to be displayed on the first partitioned region and the second partitioned region, respectively.

9. The multimedia device of claim 7, wherein the receiving unit is configured to receive at least two contents and wherein the control unit controls video data of the at least two contents to be displayed on the first partitioned region and the second partitioned region, respectively.

10. A method of controlling a multimedia device, which includes a guide bar and a flexible display configured to be rolled up on an outer circumference of the guide bar, the method comprising the steps of:

receiving a content and metadata corresponding to the content from a source device;

extracting an aspect ratio information from the received metadata; and

adjusting an extent of the flexible display rolled up on the outer circumference of the flexible display in accordance with the extracted aspect ratio information.

13. The method of claim 10, further comprising the steps of:

sensing a user'"'"'s eye using a sensor; and

adjusting a height of the guide bar to enable the sensor and the user'"'"'s eye to be situated in parallel with each other on a same level.

14. The method of claim 10, further comprising the steps of:

detecting caption data from the received metadata; and

if the caption data is detected, controlling a video data of the received content and the caption data to be displayed on a first partitioned region of the region of the flexible display not rolled up on the outer circumference of the guide bar and a second partitioned region of the region of the flexible display not rolled up on the outer circumference of the guide bar, respectively.

15. The method of claim 14, wherein at least two caption data are detected from the received metadata.

11. The method of claim 11, further comprising the step of saving a function or lookup table for determining a vertical width of a region in the flexible display not rolled up on the outer circumference of the guide bar in accordance with an aspect ratio of a screen in the flexible display in a storage unit.

12. The method of claim 11, the step of adjusting the extent of the flexible display rolled up on the outer circumference of the flexible display, comprising the steps of:

detecting the function or a value in the lookup table by accessing the storage unit; and

determining the vertical width of the region in the flexible display not rolled up on the outer circumference of the guide bar using the detected function or value in the lookup table.

16. A method of controlling a multimedia device, which includes a guide bar and a flexible display configured to be rolled up on an outer circumference of the guide bar, the method comprising the steps of:

receiving a content and metadata corresponding to the content from a source device;

receiving a command signal for selecting an aspect ratio of a screen in the flexible display; and

adjusting an extent of the flexible display rolled up on the outer circumference of the flexible display in accordance with the received command signal.

17. The method of claim 16, further comprising the step of saving a function or lookup table for determining a vertical width of a region in the flexible display not rolled up on the outer circumference of the guide bar in accordance with an aspect ratio of the screen in the flexible display in a storage unit.

18. The method of claim 17, the step of adjusting the extent of the flexible display rolled up on the outer circumference of the flexible display, comprising the steps of:

detecting the function or a value in the lookup table by accessing the storage unit; and

determining the vertical width of the region in the flexible display not rolled up on the outer circumference of the guide bar using the detected function or value in the lookup table.

19. The method of claim 16, further comprising the steps of:

sensing a user'"'"'s eye using a sensor; and

adjusting a height of the guide bar to enable the sensor and the user'"'"'s eye to be situated in parallel with each other on a same level.

20. The method of claim 16, further comprising the steps of:

detecting caption data from the received metadata; and

if the caption data is detected, controlling a video data of the received content and the caption data to be displayed on a first partitioned region of the region of the flexible display not rolled up on the outer circumference of the guide bar and a second partitioned region of the region of the flexible display not rolled up on the outer circumference of the guide bar, respectively.
