Abstract

Disclosed are a display device and a control method thereof, and a display system and a control method, the display device including: a signal processor which processes an image signal; a display unit which displays on a screen an image based on the image signal processed by the signal processor; and a controller which receives an input from at least one touch pad mapped to the screen of the display unit and displays a shape of the pointer corresponding to a touch state of the touch pad.

Claims

1. A display device comprising:

a signal processor which processes an image signal;

a display unit which displays on a screen an image based on the image signal processed by the signal processor; and

a controller which receives an input from at least one touch pad mapped to the screen of the display unit and displays a shape of the pointer corresponding to a touch state of the touch pad.

2. The display device according to claim 1, wherein the controller further displays the pointer at a position on the screen corresponding to a location of the touch pad touched by a user.

3. The display device according to claim 1, further comprising a signal receiver which receives the image signal.

4. The display device according to claim 1, wherein the touch pad comprises a plurality of areas, and the controller further displays different pointers corresponding to the plurality of touched areas of the touch pad.

5. The display device according to claim 1, wherein the controller receives the input from a remote controller comprising the touch pad.

6. The display device according to claim 1, wherein the pointer is shaped like a human finger, and the controller further displays the pointer corresponding to a bending of a user'"'"'s finger.

7. The display device according to claim 1, further comprising a signal receiver which receives the image signal.

8. The display device according to claim 1, wherein the controller further displays the pointer in a predetermined shape if a user is adjacent to the touch pad.

9. The display device according to claim 1, wherein the touch state includes at least one of a distance between a user'"'"'s finger and the touch pad and whether the user'"'"'s finger is touching the touch pad.

10. The display device according to claim 1, wherein the touch state is based on a capacitance value.

11. The display device according to claim 10, wherein the capacitance is based on at least one of a distance of the user'"'"'s finger from the touch pad and whether the user'"'"'s finger is touching the touch pad.

12. A display system comprising:

a remote controller which comprises at least one touch pad; and

a display device, including a screen mapped to the touch pad, which receives an input from the remote controller and displays a pointer which is changed in shape corresponding to a touch state of the touch pad.

13. A control method of a display device, the method comprising:

receiving an input from at least one touch pad mapped to a screen of the display device; and

displaying a pointer which changes shape corresponding to a touch state of the touch pad.

14. The method according to claim 13, further comprising displaying the pointer at a position on the screen corresponding to a location of the touch pad touched by a user.

15. The method according to claim 13, further comprising receiving an image signal.

16. The method according to claim 13, further comprising displaying the pointer in a predetermined shape if a user is adjacent to the touch pad.

17. The method according to claim 13, further comprising displaying the pointer corresponding to a bending of a user'"'"'s finger.

18. The method according to claim 13, wherein the touch state includes at least one of a distance between the user'"'"'s finger and the touch pad and whether the user'"'"'s finger is touching the touch pad.

19. The method according to claim 13, wherein the touch state is based on a capacitance value.

20. The method according to claim 19, wherein the capacitance is based on at least one of a distance of the user'"'"'s finger from the touch pad and whether the user'"'"'s finger is touching the touch pad.

21. A control method of a display system including a display device and a remote controller, the method comprising:

outputting a signal from the remote controller which includes at least one touch pad;

receiving, at the display device, the signal output from the remote controller, wherein the display device includes a screen mapped to the touch pad; and

displaying a pointer which changes in shape corresponding to a user'"'"'s touching of the touch pad.
