[0010] (Description of information display devices related to the information display device of the present disclosure) FIG. 1 is a diagram showing an example of information display according to the present disclosure. FIG. 2 is a diagram showing an example of degenerated display when a display defect occurs in a related information display device. FIG. 3(a) is a diagram showing an example of normal display on an information display device according to the present disclosure, and FIG. 3(b) is a diagram showing an example of degenerated display when a display defect occurs on an information display device according to the present disclosure. Hereinafter, the information display device according to the present disclosure and related information display devices will be described with reference to FIGS. 1 to 3.

[0011] The information display device 10 of the present disclosure is an information display device that displays meaningful information in rows or columns. The information display device of the present disclosure also displays information using a plurality of display elements arranged on a single display panel. For example, the information display device of the present disclosure can be used as an information display device that displays flight information.

[0012] 1 shows an overview of an information display device 10 that displays flight information. For example, the information display device 10 includes a server 110, related systems 109 such as an airline system and a BHS (Baggage Handling System), input / output terminals 111 such as an airline input / output terminal and a customs input / output terminal, and a network 112.

[0013] The server 110 is an information processing device. FIG. 8 is a block diagram showing the configuration of an information processing device according to the present disclosure. As shown in FIG. 8, the information processing device 800 includes a processor 801 that executes a program to perform processing, and a memory 802 that stores the program. The server 110 is connected to an associated system 109, an input / output terminal 111, and a network 112. The server 110 manages the display of the information display device. The server 110 acquires information from the associated system 109 and displays a screen 104 at the check-in counter via the network 112. The server 110 acquires information from the associated system 109 and displays a screen 102 in the departure concourse via the network 112. The server 110 acquires information from the associated system 109 and displays a screen 103 in the gate lounge via the network 112. The server 110 acquires information from the associated system 109 and displays a screen 101 at the boarding gate via the network 112.

[0014] Similarly, the server 110 acquires information from the input / output terminal 111 and displays screen 108 in the arrival lobby via the network 112. The server 110 acquires information from the input / output terminal 111 and displays screen 107 at customs via the network 112. The server 110 acquires information from the input / output terminal 111 and displays screen 106 at the baggage claim area via the network 112. The server 110 acquires information from the input / output terminal 111 and displays screen 105 at immigration via the network 112.

[0015] In this way, when displaying flight information, each line displays one meaningful piece of information.

[0016] As shown in Figure 2, a related information display device visually discovered a display defect in an LED block in one of its display panels, and implemented a degenerated display. The degenerated display involved erasing the entire display on one display panel, sliding the first screen onto the second display panel, and displaying the second screen onto the third display panel.

[0017] In this way, even if a display defect occurs in a part of one display device, a large amount of information across multiple rows and columns is deleted. Therefore, the amount of information displayed by the related information display device is significantly reduced. Also, since the display defect is detected visually, it may not be detected quickly or accurately.

[0018] The information display device of the present disclosure displays one meaningful piece of information per row, as shown in Fig. 3(a). The information display device of the present disclosure also displays multiple rows. When a display defect occurs, the information display device of the present disclosure skips the row or column with the display defect and displays the information skipped to the next row or column, as shown in Fig. 3(b).

[0019] By doing this, even if some display elements of a single display device have a display defect, only a small amount of information is deleted. Also, the display defect is determined using an information processing device rather than visual inspection. This allows for quick and accurate detection and correction of display defects.

[0020] (Description of Information Display Device According to Embodiment) Fig. 4 is a diagram showing an outline of the configuration of an information display device according to the present disclosure. Fig. 5 is a block diagram showing the configuration of an information display device according to the present disclosure. An example of the configuration of information display device 10 will be described below with reference to Figs. 4 and 5.

[0021] As shown in FIG. 4, the information display device 10 includes an imaging unit 401, a display defect detection unit 402, a display screen generation unit 403, a display unit control unit 404, and a display unit 405.

[0022] 5, the display screen generation unit 403 includes a display screen generation function 505 and a transmission function 508. The display screen generation function 505 acquires information from a connected flight information database 506 and a style sheet database 507, and generates a screen to be displayed. The generated screen transmits the display screen information to the connected display error detection unit 402 (1).

[0023] Furthermore, the display screen generation function 505 transmits the display screen to the transmission function 508 (2-1). The transmission function 508 transmits the display screen to the connected display unit control unit 404. The display unit control unit 404 includes a reception function 509 and a screen display function 510. The reception function 509 receives the display screen from the transmission function 508 (2-2). The reception function 509 transmits the display screen to the screen display function 510 (3-1). The screen display function 510 transmits the display screen to the connected display unit 405 and displays the screen (3-2).

[0024] The imaging unit 401 includes a video capture 501 and a transmission function 502. The imaging unit 401 captures an image of the display unit 405 using the video capture 501. The captured image of the display unit 405 is transmitted to the transmission function 502 (4-1). The transmission function 502 transmits the captured image of the display unit 405 to the connected display defect detection unit 402 (4-2).

[0025] The display defect detection unit 402 includes a defect position identification function 503. The display defect detection unit 402 determines whether or not there is an error in the display of the imaged display unit from the display screen transmitted from the display screen generation function 505 and the imaged display of the display unit 405. If there is a display error, the defect position identification function 503 identifies the defect position (5). In order to determine whether or not there is a defect in the difference between the display screen transmitted from the display screen generation function 505 and the imaged display screen, the display defect detection unit 402 may be connected to a deviation information database 504, which is a deviation information storage unit that stores the difference in update time, and the timing of the display and the image may be synchronized.

[0026] Then, the display defect detection unit 402 transmits the identified defect position to the display screen generation function (6-1). The display screen generation function generates a corrected screen and transmits it to the transmission function 508 (6-2). The transmission function 508 transmits the corrected screen to the reception function 509 (6-3), and the reception function 509 transmits the corrected screen to the screen display function 510 (6-4). Finally, the screen display function 510 transmits the corrected screen to the display unit 405 (6-5), and the display unit 405 displays the corrected screen.

[0027] In this way, by taking the difference between the displayed screen and the captured screen, it is determined whether there is an error in the display and display defects are detected. Therefore, display defects can be found more quickly and accurately than by visual inspection. The display defect detection unit 402 and the display screen generation unit 403 may be read as a display defect detection means and a display image generation means.

[0028] (Explanation of information display method according to embodiment) 6 is a flowchart of the information display method according to the present disclosure. The information display method using the information display device 10 according to the embodiment will be described below with reference to FIG.

[0029] As shown in FIG. 6, first, a display screen is generated (step S601). Display screen generation unit 403 generates a display screen. Next, the display screen is transmitted (step S602). Display screen generation unit 403 transmits the display screen to display unit 405 via display unit control unit 404. Next, display unit 405 displays the display screen (step S603). Next, it is determined whether a display defect has been detected (step S604). It is determined whether display defect detection unit 402 has detected a display defect. If a display defect has not been detected (No in step S604), it is determined that there is no defect (S605) and the process ends. If a display defect has been detected (Yes in step S604), the position of the defect is identified (step S606). Display defect detection unit 402 detects the position of the defect. Next, display screen generation unit 403 generates a corrected display screen (step S607), displays it, and the process ends.

[0030] (Description of an information display device according to another embodiment) 7 is a diagram showing an example of analysis of display defects by machine learning in the information display device according to the present disclosure. Another configuration example of the information display device 10 will be described below with reference to FIG.

[0031] 7, the information display device 10 of the present disclosure displays information such as scheduled times, changes, destinations / stopovers, flight numbers, boarding gates, and remarks in a matrix. Such displays are not generally displayed randomly, but are displayed according to a certain rule.

[0032] Therefore, by learning this rule by machine learning and inputting the captured display image, it is possible to determine whether there is an error in the display using an image analysis unit that outputs display defects. For example, even if San Diego is displayed, if there is no such destination / stop point in the past, it can be determined that it is a mistake and should be San Diego.

[0033] Also, if there is only a 10-minute gap between scheduled flight times for the same boarding gate, it can be determined that something is abnormal. 15:40 can be determined to be a mistake for 16:40.

[0034] In this way, the display defect detection unit can determine whether or not there is an error in the display by inputting the image of the display unit captured by the imaging unit into the image analysis unit that has undergone machine learning.

[0035] Furthermore, some or all of the processes performed by the information display device 10 described above can be implemented as a computer program. Such a program can be stored on various types of non-transitory computer-readable media and provided to a computer. Non-transitory computer-readable media include various types of tangible recording media. Examples of non-transitory computer-readable media include magnetic recording media (e.g., flexible disks, magnetic tapes, hard disk drives), magneto-optical recording media (e.g., magneto-optical disks), CD-ROMs (Read Only Memory), CD-Rs, CD-R / Ws, and semiconductor memories (e.g., mask ROMs, PROMs (Programmable ROMs), EPROMs (Erasable PROMs), flash ROMs, and RAMs (Random Access Memory)). The program may also be provided to a computer by various types of temporary computer-readable media. Examples of temporary computer-readable media include electrical signals, optical signals, and electromagnetic waves. The temporary computer-readable media can provide the program to a computer via wired communication paths such as electrical wires and optical fibers, or via wireless communication paths.
