Abstract

A display apparatus includes a cabinet; a display panel provided on the cabinet; a door provided on the cabinet and configured to be opened and closed; a first detector configured to detect opening of the door and output a first signal in response to the door being opened; an image data receiver configured to receive content data from an image source device; and a first controller configured to control the display panel to display a first image corresponding to the content data received from the image source device and control the display panel to display a second image different from the first image in response to receiving the first signal.

Claims

1. A display apparatus comprising:

a cabinet;

a display panel provided on the cabinet;

a door provided on the cabinet and configured to be opened and closed;

a first detector configured to detect opening of the door and output a first signal in response to the door being opened;

an image data receiver configured to receive content data from an image source device;

a first controller configured to control the display panel to display a first image corresponding to the content data received from the image source device and control the display panel to display a second image different from the first image in response to receiving the first signal;

a second controller configured to receive the first signal from the first detector in response to the door being opened; and

a transmitter configured to receive the first signal from the first detector and transmit the first signal to the image source device,

wherein the first detector comprises a door switch, and

wherein the door switch comprises;

first and second terminals connected to the transmitter and being separated from each other;

third and fourth terminals connected to the second controller and being separated from each other; and

a switch body configured to electrically connect the first and second terminals or electrically connect the third and fourth terminals based on the door being opened or closed.

2. The display apparatus according to claim 1, wherein the first controller is further configured to control the display panel to display the second image in response to receiving the first signal while the first controller is connected to the image source device.

3. The display apparatus according to claim 1, further comprising

a memory,

wherein the second controller is configured to store door status information in the memory in response to receiving the first signal.

4. The display apparatus according to claim 3, wherein first power is independently supplied to the first detector, the memory and the second controller separate from second power being supplied to the display panel and the first controller.

5. The display apparatus according to claim 1,

wherein the first detector is configured to output the first signal to both the second controller and the transmitter in response to detecting the door being opened.

6. The display apparatus according to claim 5, wherein the first detector comprises an infrared sensor,

wherein the infrared sensor comprises:

a light emitter configured to emit light; and

a light receiver configured to receive the light emitted from the light emitter based on the door being opened or closed.

7. A display system comprising:

an image source device; and

a plurality of display apparatuses configured to receive at least one content data from the image source device and display a first image corresponding to the at least one content data,

wherein at least one display apparatus of the plurality of display apparatuses comprises;

a cabinet;

a display panel provided on the cabinet;

a door provided on the cabinet and configured to be opened and closed;

a first detector configured to detect opening of the door and output a first signal in response to the door being opened;

an image data receiver configured to receive at least one content data from the image source device;

a first controller configured to control the display panel to display the first image corresponding to the at least one content data and control the display panel to display a second image different from the first image in response to receiving the first signal;

a memory;

a second controller configured to receive the first signal from the first detector and configured to store door status information in the memory in response to receiving the first signal; and

a first transmitter configured to receive the first signal from the first detector and transmit the first signal to the image source device,

wherein the image source device comprises;

a second transmitter configured to transmit the at least one content data to the plurality of display apparatuses,

a first receiver configured to receive the first signal from the at least one display apparatus, and

a third controller configured to stop transmission of the at least one content data to the plurality of display apparatuses in response to receiving of the first signal.

8. The display system according to claim 7, wherein first power is independently supplied to the first detector, the memory and the second controller separate from second power being supplied to the display panel and the first controller.

9. The display system according to claim 7, wherein the third controller is configured to receive the door status information from the plurality of display apparatuses when the first signal is received, and identify the at least one display apparatus based on the door status information.

10. The display system according to claim 9,

wherein the third controller is configured to transmit image data of a third image to warn the door of the at least one display apparatus being opened, and

wherein the first controller is configured to display the third image on the display panel.

11. The display system according to claim 9, wherein the third controller is configured to determine system check or unauthorized system intrusion of the at least one display apparatus.

12. The display system according to claim 11, wherein the third controller is configured to continue transmission of the at least one content data to the plurality of display apparatuses through the second transmitter in response to determining the system check being performed on the at least one display apparatus, and

wherein the third controller is configured to stop the transmission of the at least one content data through the second transmitter in response to determining the unauthorized system intrusion occurring on the at least one display apparatus.

13. A display system comprising:

an image source device configured to provide at least one content data; and

a display device comprising a plurality of display apparatuses and configured to display a first image corresponding to the at least one content data,

wherein each of the plurality of display apparatuses comprises;

a door;

a first detector configured to detect opening of the door and output a first signal in response to the door being opened; and

a first controller configured to control the display device to display a second image different from the first image in response to receiving the first signal,

wherein the image source device comprises;

a signal receiver configured to receive the first signal from the first detector; and

a second controller configured to stop transmission of the at least one content data in response to the signal receiver receiving the first signal.

14. The display system according to claim 13, wherein the second controller is configured to determine whether the first signal is based on system check or unauthorized system intrusion in the display device.

15. The display system according to claim 14, wherein the second controller is configured to continue transmission of the at least one content data to the display device in response to determining that the system check is performed on the display device, and

wherein the second controller further is configured to stop the transmission of the at least one content data in response to determining the unauthorized system intrusion in the display device.
