Accordingly, the processor 120 may generate matching information by matching the positions of the display modules to be displayed in black with the image content of FIG. 3D , and store the generated matching information in the storage unit 130 .

Meanwhile, the processor 120 may generate matching information in which the image content and the position of the display module are matched through the above-described operation for other image contents stored in the storage unit 130 , and the matching information generated in this way can be managed as an alternative content list.

Thereafter, when a failure of the display module is detected while the image is displayed on the display panel 110 , the processor 120 may cover the display module in which the failure is detected based on the matching information stored in the storage unit 130 . Alternative images can be obtained.

As such, when the location of the display module in which the failure is detected is identified, the processor 120 determines whether matching information corresponding to the location of the display module in which the failure is detected exists, based on the matching information stored in the storage unit 130 . whether or not it can be identified.

That is, since the location of the display module and the image content including the area displayed in a preset color are matched in the matching information, the processor 120 determines the location of the display module in which the failure is detected and the location of the display module included in the matching information. By comparing the positions, matching information including the position of the display module in which the failure is detected may be identified.

For example, as shown in FIG. 3C , when a failure of the display module is detected while an image is displayed on the display panel 110 , the processor 120 determines the location of the display module in which the failure is detected through the various methods described above. It can be identified that is (2,4) and (9,2).

In addition, when the location of the display module in which the failure is detected is identified, the processor 120 places (2, 4) and (2, 4) and (9,2) is identified, and the image content of FIG. 3D may be obtained as an alternative image.

Accordingly, the processor 120 may control the display panel 110 to change the image content of FIG. 3C being displayed to the image content of FIG. 3D .

Since the faulty display module in FIG. 3C is displayed in black, when the image content of FIG. 3D is displayed on the display panel 110, it is displayed as shown in FIG. 3E, and the user is located at (2,4) and (9,2) positions. It does not recognize that the display module is broken.

Meanwhile, the processor 120 may control the display panel 110 to sequentially reproduce a plurality of image contents included in the play list.

In this case, if a failure of the display module is detected while the image content included in the playlist is being displayed on the display panel 110 , the processor 120 may identify whether alternative image content exists in the playlist.

Accordingly, when the alternative image content exists in the play list, the processor 120 may control the display panel 110 to change the image content being displayed to the alternative image content.

That is, according to an embodiment of the present disclosure, when a failure of the display module is detected while image content is being displayed on the display panel 100 , the processor 120 determines whether alternative image content exists in the playlist primarily. First, if it is included in the playlist, it is possible to change the currently displayed video content to the alternative video content included in the playlist. If the alternative image content is not included in the playlist, the processor 120 may secondarily check whether there is an alternative image content among other image content stored in the storage unit 130 .

In particular, when the image content is an advertisement image displayed on a large billboard, since it is important to display the image according to the play list, the above embodiment may be meaningful.

Meanwhile, according to an embodiment of the present disclosure, when the replacement image content does not exist in the storage unit 130 , the processor 120 determines the image content currently being displayed based on the location of the display module in which the failure is detected. The display panel 110 may be controlled to display in a reduced size.

For example, as shown in FIG. 5A , when a failure of the display module at position (9,2) is detected while image content is displayed on the display panel 110 , the processor 120 controls the display module in which the failure is detected. It is determined whether matching information corresponding to the location of ' is present in the storage unit 130 . As a result of the determination, when the corresponding matching information does not exist, the processor 120 may reduce the size of the currently displayed image based on (9,2), which is the location of the display module where the failure is detected.

That is, the processor 120 displays the display modules arranged in the ninth column (ie, (9,1) to (9,7) positions) based on (9,2), which is the position of the display module in which the failure is detected. modules), the image content may be reduced and displayed on the display panel 110 as shown in FIG. 5B so that the image content is displayed on the remaining display modules.

Meanwhile, according to an embodiment of the present disclosure, when a failure of the display module is detected while the first image is displayed on the display panel 110, the processor 120 identifies the color of the display module in which the failure is detected, A second image in which an area corresponding to the location of the display module in which a failure is detected is displayed with the identified color may be acquired.

Specifically, the processor 120 may identify the color of the display module in which the failure is detected based on at least one of power supplied to each of the plurality of display modules and an image captured by a display panel on which the first image is displayed. .

For example, when the cause of the failure of the failed display module is power failure, the processor 120 may identify the color of the display module in which the failure is detected as the color of the display module itself (eg, black). Also, when receiving an image captured by the display panel 110 from the external electronic device, the processor 120 may identify the color of the defective display module displayed on the captured image as the color of the defective display module.

Accordingly, the processor 120 may acquire a second image in which an area corresponding to the location of the display module in which the failure is detected is displayed with the identified color, and change the displayed first image to the second image.

Meanwhile, according to an embodiment of the present disclosure, when a failure of the display module is detected while the first image is displayed on the display panel 110 , the processor 120 displays a color displayed at the location of the display module in which the failure is detected. It is first determined whether the color is the preset color, and only when the color is not the preset color, the second image can be acquired.

This is because, if a preset color is already displayed at the position of the display module where the failure is detected, even if the failure of the display module is detected, there is no need to change to another image. It is a flowchart showing the operation of the display system according to the
