Abstract

A display apparatus having a multi-screen displaying mode to display a plurality of images, the display apparatus comprises: a displaying part displaying an image; a location detecting part detecting location information pointed on the displaying part through a predetermined pointing device; and a controller adjusting the location information detected through the location detecting part, on a basis of an activating area of a tablet function according to a selected displaying mode when the multi-screen displaying mode is selected.

Claims

1. A display apparatus having a multi-screen displaying mode to display a plurality of images, the display apparatus comprising:

a displaying part displaying an image;

a location detecting part detecting location information pointed on the displaying part through a predetermined pointing device; and

a controller adjusting the location information detected through the location detecting part, on a basis of an activating area of a tablet function according to a selected displaying mode when the multi-screen displaying mode is selected.

2. The display apparatus according to claim 1, wherein the controller adjusts the location information so that a location pointed through the pointing device coincides with a displaying location of an image signal corresponding to the location information, on the basis of a size and a location of the activating area of the tablet function according to the selected multi-screen displaying mode.

3. The display apparatus according to claim 2, wherein the multi-screen displaying mode comprises at least one mode among PIP, PBP and POP mode.

4. The display apparatus according to claim 3, wherein the location detecting part comprises a sensor part receiving a pointing signal generated according to contact of the pointing device with the displaying part, and a location outputting part calculating the location information on the basis of the pointing signal.

5. The display apparatus according to claim 4, further comprising a memory where a set-up coordinate of the displaying location of the displaying part is stored,

wherein the location outputting part calculates the location information on the basis of the set-up coordinate.

6. The display apparatus according to claim 4, wherein the pointing signal, which is generated by the pointing device, comprises an ultrasonic signal and/or an infrared signal;

and

the sensor part comprises an ultrasonic signal sensor and/or an infrared signal sensor.

7. The display apparatus according to claim 6, further comprising a protecting window contacted by the pointing device in a front of the displaying part.

8. The display apparatus according to claim 2, wherein the location detecting part comprises a sensor part receiving a pointing signal generated according to contact of the pointing device with the displaying part, and a location outputting part calculating the location information on a basis of the pointing signal.

9. The display apparatus according to claim 8, further comprising a memory where a setting-up coordinate of a displaying location of the displaying part is stored,

wherein the location outputting part calculates the location information on a basis of the set-up coordinate.

10. The display apparatus according to claim 8, wherein the pointing signal, which is generated by the pointing device, comprises an ultrasonic signal and/or an infrared signal;

and

the sensor part comprises an ultrasonic signal sensor and/or an infrared signal sensor.

11. The display apparatus according to claim 10, further comprising a protecting window contacted by the pointing device in a front of the displaying part.

12. A display system having a multi-screen displaying mode to display a plurality of images, the display system comprising:

a signal source providing an image signal;

a displaying part receiving the image signal and displaying;

a pointing device;

a location detecting part detecting location information pointed on the displaying part through the pointing device; and

a controller adjusting the location information detected through the location detecting part, on the basis of an activating area of a tablet function in accordance with a selected displaying mode according to whether the multi-screen displaying mode is selected.

13. The display system according to claim 12, wherein the multi-screen displaying mode comprises at least one mode among PIP, PBP and POP mode.

14. The display system according to claim 13, wherein the controller adjusts the location information so that a location pointed by the pointing device coincides with a displaying location of an image signal corresponding to the location information, on the basis of a size and a location of the activating area of the tablet function according to the selected multi-screen displaying mode;

the signal source generates the image signal corresponding to the adjusted location information and provides the image signal to the displaying part.

15. The display system according to claim 14, wherein the location detecting part comprises a sensor part receiving a pointing signal generated according to contact of the pointing device with the displaying part, and a location outputting part calculating the location information on a basis of the pointing signal.

16. The display system according to claim 15, further comprising a memory where a set-up coordinate of the displaying location of the displaying part is stored;

and

wherein the location outputting part calculates the location information on the basis of the set-up coordinate.

17. The display system according to claim 16, wherein the displaying part, the location detecting part, the controller and the memory are equipped in a display apparatus.

18. The display system according to claim 15, wherein the pointing device generates the pointing signal;
