Abstract

A method and device for displaying data are discussed. According to an embodiment, the display device includes a first display unit; a first display controller configured to control the first display unit, to receive at least one content to be displayed, to check if any data included in the content is to be displayed separately, and to transmit the data to a second display controller if the checking indicates that the data is to be displayed separately; at least one second display unit; and the second display controller configured to control the second display unit to display the data received from the first display controller, wherein the first display unit is configured to display the content excluding the data under control of the first display controller, and wherein the first display unit and the second display unit are physically separated display units.

Claims

1. A method for displaying data using a display device, the display device including a first display unit, a first display controller configured to control the first display unit, at least one second display unit, and a second display controller configured to control the at least one second display unit, the method comprising:

receiving, by the first display controller, at least one content to be displayed;

checking, by the first display controller, if any data included in the at least one content is to be displayed separately;

transmitting, by the first display controller, the data to the second display controller if the checking step indicates that the data is to be displayed separately;

displaying, on the second display unit, the data under control of the second display controller; and

displaying, on the first display unit, the at least one content excluding the data under control of the first display controller.

2. The method according to claim 1, wherein the data displayed on the second display unit includes a plurality of different thumbnail images respectively from a plurality of different channels.

3. The method according to claim 2, further comprising:

receiving, by the second display controller, an input selecting one of the thumbnail images displayed on the second display unit;

transmitting the selected thumbnail image from the second display controller to the first display controller; and

displaying, on the first display unit, contents from one of the channels corresponding to the selected thumbnail image.

4. The method according to claim 1, wherein the data is one of the following:

broadcast data,

data received from a network or server, or

data stored in the display device or in an external device connected to the display device.

5. The method according to claim 1, wherein the data includes at least one of subtitle data, Electronic Program Guide (EPG) data, broadcast-related information, a thumbnail image, and caption data.

6. The method according to claim 1, wherein the second display unit is disposed at a side region of the display device, and the first display controller and the second display controller are connected to a network.

7. The method according to claim 1, wherein the displaying steps are performed simultaneously such that the data and the at least one content excluding the data are simultaneously displayed on the display device.

8. The method according to claim 1, wherein the at least one second display unit includes a plurality of second display units, and

Wherein the step of displaying, on the second display unit, the data displays the data on the plurality of second display units.

9. The method according to claim 8, wherein the data displayed on each of the plurality of second display units includes:

broadcast data,

data received from a network or server, or

data stored in the display device or in an external device connected to the display device.

10. The method according to claim 8, wherein the data displayed on a first one of the plurality of second display units is different in type and/or format from the data displayed on a second one of the plurality of second display units.

11. The method according to claim 1, wherein the first display unit and the at least one second display unit are physically separated display units.

12. A display device for displaying data, the display device comprising:

a first display unit;

a first display controller configured to control the first display unit, to receive at least one content to be displayed, to check if any data included in the at least one content is to be displayed separately, and to transmit the data to a second display controller if the checking indicates that the data is to be displayed separately;

at least one second display unit; and

the second display controller configured to control the at least one second display unit to display the data received from the first display controller,

wherein the first display unit is configured to display the at least one content excluding the data under control of the first display controller, and

wherein the first display unit and the at least one second display unit are physically separated display units.

13. The display device according to claim 12, wherein the data displayed on the second display unit includes a plurality of different thumbnail images respectively from a plurality of different channels.

14. The display device according to claim 13, wherein the second display controller is further configured to receive an input selecting one of the thumbnail images displayed on the second display unit, and to transmit the selected thumbnail image to the first display controller, and

wherein the first display unit is configured to display contents from one of the channels corresponding to the selected thumbnail image.

15. The display device according to claim 12, wherein the data is one of the following:

broadcast data,

data received from a network or server, or

data stored in the display device or in an external device connected to the display device.

16. The display device according to claim 12, wherein the data includes at least one of subtitle data, Electronic Program Guide (EPG) data, broadcast-related information, a thumbnail image, and caption data.

17. The display device according to claim 12, wherein the first display controller checks if any data included in the at least one content is to be displayed separately according to an external input.

18. The display device according to claim 12, wherein the second display unit is disposed at a side region of the display device, and the first display controller and the second display controller are connected to a network.

19. The display device according to claim 12, wherein the data and the at least one content excluding the data are simultaneously displayed on the first display unit and the at least one second display unit, respectively.

20. The display device according to claim 12, wherein the at least one second display unit includes a plurality of second display units, and

Wherein the second display units displays the data.

21. The display device according to claim 20, wherein the data displayed on each of the plurality of second display units includes:

broadcast data,

data received from a network or server, or

data stored in the display device or in an external device connected to the display device.

22. The display device according to claim 20, wherein the data displayed on a first one of the plurality of second display units is different in type and/or format from the data displayed on a second one of the plurality of second display units.
