Abstract

A display system includes a server supplying an image signal through a network communication and at least one display apparatus displaying the image signal received through the network communication. The at least one display apparatus includes a display unit displaying the image signal thereon, a sensor device sensing a color coordinate of the image signal displayed on the display unit and a communication unit communicating with the server. The server adjusts the image signal with a reference color coordinate and supplies the adjusted image signal to an originating display apparatus from among the at least one display apparatus which supplied the color coordinate to the server.

Claims

1. A display system comprising:

a server which supplies an image signal through a network; and

a plurality of display apparatuses which display the image signal received through the network,

wherein at least one display apparatus of the plurality of display apparatuses comprises a display unit which displays the image signal thereon, a sensor device which senses a color coordinate of the image signal displayed on the display unit, and a communication unit which communicates with the server, and

wherein the server receives the sensed color coordinate from the at least one display apparatus, adjusts the image signal with a reference color coordinate, and supplies the adjusted image signal to the at least one display apparatus supplying the sensed color coordinate.

2. The display system according to claim 1, wherein sensor devices are installed in at least two of the plurality of display apparatuses.

3. The display system according to claim 2, wherein the communication unit communicates with the server through a wired local area network (LAN) or a wireless LAN.

4. The display system according to claim 1, wherein the one display apparatus further comprises a storage unit storing information therein, and

the server receives the color coordinate and the information from the one display apparatus.

5. The display system according to claim 4, wherein the information comprises an internet protocol (IP) address, and

the server supplies the adjusted image signal to the received IP address.

6. The display system according to claim 1, wherein the color coordinate sensed by the sensor device is generated by sensing the image signal displayed on a front surface of the display unit.

7. The display system according to claim 1, wherein the reference color coordinate is stored in the server by a user.

8. The display system according to claim 7, wherein the server adjusts the image signal when a deviation between the received color coordinate and the reference color coordinate is outside of a range.

9. The display system according to claim 1, wherein the reference color coordinate comprises a color coordinate supplied from a selected display apparatus of the plurality of display apparatuses selected by the server.

10. The display system according to claim 9, wherein the server adjusts the image signal transmitted to another of the plurality of display apparatuses with the reference color coordinate when a deviation between the reference color coordinate and the color coordinate supplied by the another of the plurality of display apparatuses is outside of a range, and supplies the adjusted image signal to the another of the plurality of display apparatuses.

11. A display apparatus which displays an image signal supplied from a server through via a network, the display apparatus comprising:

a display unit which displays the image signal thereon;

a sensor device which senses a color coordinate of the image signal displayed on the display unit; and

a communication unit which communicates with the server through the network,

wherein the communication unit transmits the color coordinate to the server, and receives an adjusted image signal corresponding to the transmitted color coordinate.

12. The display apparatus according to claim 11, further comprising a storage unit which stores information therein,

wherein the communication unit supplies the color coordinate and the information to the server.

13. The display apparatus according to claim 12, wherein the information comprises an internet protocol (IP) address, and

the communication unit supplies the color coordinate and the IP address to the server.

14. The display apparatus according to claim 11, wherein the sensor device is provided in a front surface of the display unit and senses the image signal displayed on the display unit to generate the color coordinate sensed by the sensor device.

15. The display apparatus according to claim 11, wherein the communication unit communicates with the server through a wired local area network (LAN) or a wireless LAN.

16. A control method of a display apparatus which displays an image signal supplied by a server through a network, the control method comprising:

displaying the image signal;

sensing a color coordinate of the displayed image signal;

transmitting the color coordinate to the server; and

receiving an adjusted image signal corresponding to the transmitted color coordinate.

17. The control method according to claim 16, further comprising storing information,

wherein the transmitting the color coordinate to the server comprises supplying the color coordinate together with the information to the server.

18. The control method according to claim 17, wherein the information comprises an internet protocol (IP) address, and the transmitting the color coordinate to the server comprises supplying the color coordinate and the IP address to the server.
