Abstract

A display apparatus includes a display unit, a storage unit which stores a zone name and standard time information corresponding to the zone name, a user interface (UI) generator which generates a time information image, and a controller which receives local real-time information from an external source, calculates a time corresponding to a selected zone based on the local real-time information and the standard time information, and controls the UI generator to generate the time information image containing the calculated time to be displayed on the display unit.

Claims

1. A display apparatus, comprising:

a display unit;

a storage unit which stores a zone name and standard time information corresponding to the zone name;

a user interface (UI) generator which generates a time information image; and

a controller which receives local real-time information from an external source, calculates a time corresponding to a selected zone based on the local real-time information and the standard time information, and controls the UI generator to generate the time information image containing the calculated time to be displayed on the display unit.

2. The display apparatus according to claim 1, wherein the time information image comprises a world map and time information displayed on the world map.

3. The display apparatus according to claim 2, wherein the time information image further comprises a time bar movable on the world map and indicating a zone having same standard time information.

4. The display apparatus according to claim 3, wherein the time bar is positioned in the selected zone when receiving the selection signal.

5. The display apparatus according to claim 3, wherein the time information image further comprises a zone information item showing at least one zone name belong to the time bar and a time corresponding to the zone name.

6. The display apparatus according to claim 3, wherein the time information image further comprises a moving item for moving the time bar.

7. The display apparatus according to claim 2, wherein the time information image further comprises a local time item showing the local real-time information.

8. The display apparatus according to claim 1, further comprising a user input unit which generates a control signal to display the time information image on the display unit.

9. The display apparatus according to claim 8, wherein the control signal is received while the display unit does not display an image.

10. The display apparatus according to claim 1, further comprising a touch panel internally or externally provided in the display unit to input a selection signal indicating the selected zone.

11. The display apparatus according to claim 1, wherein the local real-time information is received from an external server.

12. The display apparatus according to claim 11, wherein the local real-time information is received from the external server through a local area network (LAN).

13. A display apparatus, comprising:

a display unit;

a storage unit which stores a predetermined zone name and standard time information corresponding to the zone name;

a user interface (UI) generator which generates a world map image containing time information; and

a controller which calculates a time corresponding to a selected zone based on local real-time information and the standard time information, and controls the UI generator to display the world map image containing the calculated time on the display unit.

14. A display system comprising:

a server which has local real-time information; and

a display apparatus comprising a display unit, a storage unit which stores a zone name and standard time information corresponding to the zone name, and a controller which receives the local real-time information from the server, calculates a time corresponding to a selected zone based on the local real-time information and the standard time information, and controls a user interface (UI) generator to display a time information image containing the calculated time on the display unit.

15. The display system according to claim 14, wherein the controller requests the standard time information corresponding to the selected zone from the server if the standard time information corresponding to the selected zone is not stored in the storage unit.

16. The display system according to claim 14, wherein the server and the display apparatus are connected through a local area network (LAN).

17. A method of controlling a display apparatus comprising a display unit and a storage unit storing a zone name and standard time information corresponding to the zone name, the method comprising:

receiving a selection signal for selecting a zone;

receiving local real-time information from an external source;

calculating a time corresponding to a selected zone based on the local real-time information and the standard time information; and

displaying a time information image containing the calculated time on the display unit.

18. The method according to claim 17, wherein the time information image comprises a world map and time information displayed on the world map.

19. The method according to claim 17, further comprising receiving a control signal to display the time information image on the display unit.

20. The method according to claim 18, wherein the time information image comprises a time bar movable on the world map and indicating a zone having same standard time information,

the method further comprising positioning the time bar in the selected zone when a selection signal is received.

21. The method according to claim 19, wherein the control signal is received while the display unit does not display an image.
