Abstract

A display device including a display; an interface unit configured to receive a request from a remote controller; and a controller configured to in response to a first request received from the remote controller, display a list of previously-viewed content including at least a first item corresponding to a first previously-viewed content, a second item corresponding to a second previously-viewed content and a third item corresponding a third previously-viewed content, wherein the first item, the second item, and the third item are displayed in an order that has been previously viewed, in response to a second request received from the remote controller, display a fourth content on the display, in response to a third request from the remote controller to display the list of previously-viewed content, delete the first item in the list of previously-viewed content and display the list of previously-viewed content including the second item, the third item and a fourth item corresponding to the fourth displayed content, in response to a fourth request received from the remote controller, display a fifth content on the display, and in response to a fifth request from the remote controller to display the list of previously-viewed content, delete the second item in the list of previously-viewed content and display the list of previously-viewed content including the third item, the fourth item and a fifth item corresponding to the fifth displayed content.

Claims

1. A display device, comprising:

a display;

an interface unit configured to receive a request from a remote controller; and

a controller configured to;

in response to a first request received from the remote controller, display a list of previously-viewed content including at least a first item corresponding to a first previously-viewed content, a second item corresponding to a second previously-viewed content and a third item corresponding a third previously-viewed content, wherein the first item, the second item, and the third item are displayed in an order that the previously-viewed content has been viewed,

in response to a second request received from the remote controller, display a fourth content on the display,

in response to a third request from the remote controller to display the list of previously-viewed content, delete the first item in the list of previously-viewed content and display the list of previously-viewed content including the second item, the third item and a fourth item corresponding to the fourth displayed content,

in response to a fourth request received from the remote controller, display a fifth content on the display, and

in response to a fifth request from the remote controller to display the list of previously-viewed content, delete the second item in the list of previously-viewed content and display the list of previously-viewed content including the third item, the fourth item and a fifth item corresponding to the fifth displayed content,

wherein the controller is further configured to display the list of previously-viewed content on an initial screen when the display device is turned on.

2. The display device of claim 1, wherein the first item includes information identifying a content provider.

3. The display device of claim 1, wherein the controller is further configured to:

in response to the first item being selected, display the first previously-viewed content on the display.

4. The display device of claim 1, further comprising:

a broadcast receiver configured to receive a broadcast signal,

wherein the controller is further configured to;

display a broadcast program included in the broadcast signal on the display.

5. The display device of claim 4, wherein the broadcasting program corresponds to a real-time broadcasting content received by a tuner included in the broadcast receiver.

6. The display device of claim 1, further comprising:

an image signal processor including a decoder for decoding a video data; and

a scaler configured to convert the video data to be fit for a vertical frequency, a resolution, and an aspect ratio, which are an output standard of the display.

7. The display device of claim 1, wherein the list of previously-viewed content includes a predetermined number of display areas for displaying the first item, the second item, and the third item.

8. The display device of claim 7, wherein the predetermined number of areas is three or greater than three.

9. The display device of claim 8, when the predetermined number of display areas include a blank area when the list of previously-viewed content includes two items or less than two items.

10. The display device according to claim 1, wherein the first item, the second item, the third item, the fourth item, and the fifth item have a square shape.

11. The display device of claim 1, wherein the first item includes text identifying the first previously-viewed content.

12. The display device of claim 11, wherein the first item further includes an image identifying the first previously-viewed content.

13. The display device of claim 1, wherein the controller is further configured to:

display a list of recommended applications that can be executed on the display device.

14. A method of controlling a display device, the method comprising:

in response to a first request received from a remote controller, displaying, via a display of the display device, a list of previously-viewed content including at least a first item corresponding to a first previously-viewed content, a second item corresponding to a second previously-viewed content and a third item corresponding a third previously-viewed content, wherein the first item, the second item, and the third item are displayed in an order that the previously-viewed content has been viewed;

in response to a second request received from the remote controller, displaying a fourth content on the display;

in response to a third request from the remote controller to display the list of previously-viewed content, deleting, via a controller of the display device, the first item in the list of previously-viewed content and displaying the list of previously-viewed content including the second item, the third item and a fourth item corresponding to the fourth displayed content;

in response to a fourth request received from the remote controller, displaying a fifth content on the display; and

in response to a fifth request from the remote controller to display the list of previously-viewed content, deleting, via the controller, the second item in the list of previously-viewed content and displaying the list of previously-viewed content including the third item, the fourth item and a fifth item corresponding to the fifth displayed content,

wherein the method further comprises;

displaying the list of previously-viewed content on an initial screen when the display device is turned on.

15. The method of claim 14, wherein the first item includes information identifying a content provider.

16. The method of claim 14, further comprising:

in response to the first item being selected, displaying the first previously-viewed content on the display.

17. The method of claim 14, further comprising:

receiving, via a broadcast receiver, a broadcast signal; and

displaying a broadcast program included in the broadcast signal on the display.

18. The method of claim 17, wherein the broadcasting program corresponds to a real-time broadcasting content received by a tuner included in the broadcast receiver.
