As shown in FIG. 1, the display system 1 according to the first embodiment of the present invention includes a plurality of display devices 10 (10a, 10b, 10c, and 10d) and a plurality of video signal generators 20 (20a, and 10d). 20b) and the communication line 30. In the following description, when the display device 10a, the display device 10b, the display device 10c, and the display device 10d are not specified, they are simply referred to as the display device 10, and the video signal generator 20a and the video signal generator 20b are specified. If not, it is simply referred to as a video signal generator 20.

As shown in the figure, the display devices 10b are arranged side by side above the display device 10a, the display devices 10c are arranged side by side next to the display device 10a, and the display devices 10d are arranged side by side next to the display device 10b. As a result, a multi-display composed of four display devices 10 is constructed. The multi-display receives a video signal transmitted from the video signal generator 20 via the communication line 30 and displays a video based on the video signal.

FIG. 2 is a schematic view showing a state of the back surface of the display device 10 in the display system 1 according to the first embodiment of the present invention. As shown in the figure, a communication input unit 101, a communication output unit 102, and an operation input unit 104 are provided on the back surface of the display device 10, respectively. Then, the communication output unit 102 of the display device 10a and the communication input unit 101 of the display device 10c, the communication output unit 102 of the display device 10c and the communication input unit 101 of the display device 10b, and the communication output unit 102 and the display device of the display device 10b. The communication input unit 101 of 10d is communicated and connected by a communication line 40, respectively.

That is, the four display devices 10 are communicated and connected in series in the order of the display device 10a, the display device 10c, the display device 10b, and the display device 10d. By communicating with the display device 10 in this way, information can be sequentially transmitted from the display device 10a (the most upstream display device 10) to the display device 10d (the most downstream display device 10).

It is assumed that the display device 10 is installed near the wall surface, and that the back surface of the display device 10 and the wall surface are adjacent to each other. Therefore, when the user wants to change the setting of the display device 10a or the display device 10c arranged at the bottom of the multi-display, the display device 10a or the display device 10c is provided with legs. The setting can be changed (operation input) by reaching from below the display device 10a or the display device 10c to the back surface and operating the operation input unit 104. However, when it is desired to change the settings of the display device 10b or the display device 10d, even if the display device 10a or the display device 10c is reached from below to the back surface, the operation input unit 104 of the display device 10b or the display device 10d is reached. Cannot change settings (operation input) because it is out of reach.

Therefore, the display system 1 according to the present invention transmits the setting information (control information) related to the setting change and the like from the display device 10 on the upstream side to the display device 10 on the downstream side by the above-mentioned communication connection, thereby transmitting all the display devices. It enables processing such as changing the settings of 10.

Not only the multi-display in which the display devices 10 are arranged in 2 rows and 2 columns as in this embodiment, but also all the multi-displays in which the display devices 10 are arranged in 10 rows and 10 columns are similarly used. The setting of the display device 10 can be changed.

Although not shown in FIG. 2, each display device 10 is provided with a video signal input unit and a video signal output unit for transmitting a video signal indicating a video to be displayed for multi-display, and can display the video signal. A configuration may be configured in which communication is connected in series between a plurality of display devices 10 using a communication line to be transmitted. Of course, each display device 10 may be connected to the video signal generator 20 by communication, and each display device 10 may be configured to acquire the video signal individually. Further, the transmitted information is configured so that the video signal (video information) and the setting information (control information) are transmitted using separate communication lines, but the same communication line is used for transmission. It may be a configuration.

FIG. 3 is a schematic view showing the setting of identification information of the display device 10 in the display system 1 according to the first embodiment of the present invention.
Before the display device 10 is installed adjacent to the wall surface, the identification information is set in advance by the user. The identification information is set by using, for example, an OSD (On-Screen Display; display display setting) function, which is a function provided in the display device 10.

FIG. 3 shows a state in which the identification information is set on each display device 10 and the identification information is displayed by the OSD. As shown, the display device 10a, the display device 10b, the display device 10c, and the display device 10d in FIG. 3 have "ID: 1", "ID: 3", "ID: 2", and "ID:", respectively. The display device 10a, the display device 10b, the display device 10c, and the display device 10d in FIG. 3, which are displayed as "4", are referred to as "1", "3", "2", and "4", respectively. It means that the ID (Identifier) is set.

FIG. 4 is a schematic view showing the setting of the display device 10 to be operated in the display system 1 according to the first embodiment of the present invention.
As shown in the figure, the display device 10a displays "target monitor: 3" and "individual control: ON". The display of "target monitor: 3" is a state in which the target monitor to be set by the operation keys of the display device 10a is a monitor to which the ID "3" is assigned (that is, the display device 10b). Show that. Further, for the display of "individual control: ON", a function (individual control function) that allows setting of another display device 10 instead of the own display device 10a by the operation key of the display device 10a is effective (ON). Indicates that the state is (second mode).

It should be noted that the individual control function may be automatically changed to the ON state (second mode) when the monitor to be operated is selected by the user using the OSD function or the like. Alternatively, the configuration may be such that the user selects the monitor to be operated when the individual control function is changed to the ON state (second mode) by the user.

As described above, according to the display system 1 according to the first embodiment of the present invention, the user uses the operation input unit 104 (operation key) provided in the display device 10 on the upstream side to display the downstream side. Operations such as changing the settings of the device 10 can be performed.

FIG. 5 is a block diagram showing a functional configuration of the display device 10 in the display system 1 according to the first embodiment of the present invention.
As shown in the figure, the display device 10 includes a communication input unit 101, a communication output unit 102, a communication interface 103, an operation input unit 104, a display unit 105, a video signal input unit 106a, and a video signal input unit 106b. The video signal output unit 107, the video switch 108, the video control unit 109, the output video control unit 110, the control unit 111, the ID control unit 112, the storage unit 113, the cable detection unit 114, and the like. Consists of including.

The communication input unit 101 is setting information (control information) related to the setting of the display device 10 and identification information for identifying the display device 10 to be set from the communication output unit 102 described later of the other connected display device 10. It is an input terminal for acquiring the target identification information.
The communication output unit 102 is an output terminal that outputs setting information (control information) and target identification information to another connected display device 10.
The communication interface 103 transmits / receives information to / from another display device 10 by the communication input unit 101 and the communication output unit 102.

The operation input unit 104 is an input interface (for example, an operation key) that receives an operation input by the user. For example, the operation input unit 104 inputs setting information (control information) related to the setting of the display device 10 and target identification information for identifying the display device 10 to be set based on the operation by the user. The operation input unit 104 outputs various information based on the operation input to the control unit 111.
The display unit 105 is a display that displays an image based on an image signal input from the image signal input unit 106a or the image signal input unit 106b, which will be described later, for example, a liquid crystal display (LCD) or an organic EL (electroluminescence) display. Is.

The video signal input unit 106a and the video signal input unit 106b acquire the video signals transmitted from the video signal generator 20a and the video signal generator 20b, respectively, via the communication line 30. Alternatively, the video signal input unit 106a and the video signal input unit 106b acquire the video signal transmitted from the video signal output unit 107 described later of the other display device 10 via the communication line for transmitting the video signal.

In the following description, when the video signal input unit 106a and the video signal input unit 106b are not specified, it is simply referred to as the video signal input unit 106.

For example, the video signal input unit 106 of the most upstream display device 10 acquires the video signal transmitted from the video signal generator 20, and the display device 10 on the downstream side is one upstream side of its own display device 10. The video signal output from the video signal output unit 107 of the display device 10 of the above is acquired.

The video signal output unit 107 outputs the video signal acquired by the video signal input unit 106 to the video signal input unit 106 of another display device 10 via a communication line that transmits the video signal.

The video switch 108 switches so that one of the video signals input from the video signal input unit 106a or 106b is output to the video control unit 109 described later. Further, the video switch 108 switches so that one of the video signals input from the video signal input unit 106a or 106b is output to the video signal output unit 107. The video signal output to the video control unit 109 and the video signal output to the video signal output unit 107 may be the same signal or different signals.

The video control unit 109 converts the video signal input from the video switch 108 into video data in a data format that can be displayed by the display unit 105, and outputs the video signal to the output video control unit 110 described later.

The output video control unit 110 causes the display unit 105 to display a video based on the video data input from the video control unit 109.

The control unit 111 controls each functional block of the display device 10 based on the control information (control information) based on the operation input input from the operation input unit 104. The control unit 111 includes, for example, a CPU (Central Processing Unit).

For example, the control unit 111 acquires information (control information) for setting identification information for identifying its own display device 10 from the operation input unit 104, and outputs the information (control information) to the ID control unit 112 described later and the storage unit 113 described later. ..

Further, for example, the control unit 111 is its own display device in which the target identification information acquired by the communication interface 103 via the communication input unit 101 or the target identification information acquired by the operation input unit 104 is stored in the storage unit 113. If it matches the identification information corresponding to 10, the processing such as changing the setting of its own display device 10 is executed based on the acquired setting information (control information).

Further, for example, the control unit 111 is its own display device in which the target identification information acquired by the communication interface 103 via the communication input unit 101 or the target identification information acquired by the operation input unit 104 is stored in the storage unit 113. If it is different from the identification information corresponding to 10, the target identification information and the setting information (control information) are output to another display device 10 via the communication output unit 102 by the communication interface 103.

The ID control unit 112 controls the identification information (ID) set in the display device 10. For example, when the identification information set in the display device 10 of the ID control unit 112 and the identification information set in the other display device 10 are the same (overlapping), the ID control unit 112 is different from each other. In some cases, various controls for resetting the information are performed, and in some cases, the display device 10 is controlled all at once from the most upstream display device 10 with the same identification information (ID). ..

The storage unit 113 stores various data and programs used in its own display device 10. The storage unit 113 stores, for example, identification information (ID) set in its own display device 10. The storage unit 113 includes, for example, a hard disk drive (HDD; Hard Disk Drive), a flash memory, an EEPROM (EEPROM), an Electrical Program Read Only Memory, a ROM (Read Only Memory), and a ROM (Read Only Memory; read-only memory). / Write Memory; read / write memory), or any combination thereof.

The cable detection unit 114 detects whether or not the cable (communication line 40) is connected to the input terminal (communication input unit 101). If the control unit 111 detects that the cable is not connected to the input terminal, there is no display device 10 upstream of its own display device 10, that is, its own display device 10 is the most upstream display device. It can be recognized that it is 10.

Hereinafter, the operation of the display device 10 will be described.
6 and 7 are flowcharts showing an example of the operation of the display device 10 of the display system 1 according to the first embodiment of the present invention.

First, the flowchart shown in FIG. 6 will be described. The flowchart shown in FIG. 6 is an example of the operation of the most upstream display device 10 (monitor (1)). As described above, the method of recognizing whether or not the display device 10 is the most upstream is the method of recognizing based on the fact that the cable is not connected to the input terminal, or "ID: 1" as the identification information. Any method may be used, such as a method of recognizing based on the settings.
The flowchart shown in FIG. 6 starts when an operation input for setting a monitor to be operated is made by the user in the most upstream display device 10 (monitor (1)).

(Step st001) The operation input unit 104 acquires information based on the operation of the operation keys by the user, and outputs the acquired information to the control unit 111. Then, the process proceeds to step st002.

(Step st002) The control unit 111 detects whether or not the individual control function is "ON" (valid state (second mode)). That is, the control unit 111 includes information that causes the individual control function to be "ON" (second mode) in the information acquired by the operation input unit 104, or the individual control function is already "ON" ( Detects whether or not it is the second mode). If the individual control function is "ON" (second mode), the process proceeds to step st004. If this is not the case, that is, if the individual control function is "OFF" (invalid state (first mode)), the process proceeds to step st003.

(Step st003) Since the individual control function is "OFF" (first mode), the control unit 111 has its own setting information (control information) included in the information acquired by the operation input unit 104. The processing of the display device 10 is executed (that is, it controls its own monitor (1)). This completes the processing of this flowchart.

(Step st004) The control unit 111 detects whether or not the information acquired by the operation input unit 104 is information indicating a special key. If the information acquired by the operation input unit 104 is information indicating a special key, the process proceeds to step st005. If not, the process proceeds to step st006.

The special key is a pattern of operation keys input when the user switches the individual control function to "OFF" (first mode). For example, the special key is predetermined by a combination of a plurality of keys that are not normally used.

(Step st005) The control unit 111 switches the individual control function to the "OFF" state (first mode). This completes the processing of this flowchart.

(Step st006) The communication interface 103 displays information acquired by the operation input unit 104 (information including setting information (control information) and target identification information for identifying the display device 10) via the communication output unit 102. Output to device 10 (display device 10 on the downstream side of one of its own display devices 10). This completes the processing of this flowchart.

Next, the flowchart shown in FIG. 7 will be described. The flowchart shown in FIG. 7 is an example of the operation of a display device other than the most upstream display device 10 (monitor (1)), that is, the display device 10 on the downstream side.
The flowchart shown in FIG. 7 starts when the communication input unit 101 of the display device 10 acquires information including setting information (control information) and target identification information.

(Step st011) The communication input unit 101 acquires information including setting information (control information) and target identification information output from another display device 10 via the communication line 40, and controls the acquired information. Output to unit 111. Then, the process proceeds to step st012.

(Step st012) In the control unit 111, the target identification information (ID) included in the information acquired by the communication input unit 101 is combined with the identification information (ID) that weaves the display device 10 stored in the storage unit 113. Detects whether they are the same. If they are the same, the process proceeds to step st013. If not, the process proceeds to step st014.

(Step st013) The control unit 111 executes the processing of its own display device 10 (that is, controls its own monitor) based on the setting information (control information) included in the information acquired by the communication input unit 101. .. After that, the process proceeds to step st014. If it is known that the acquired information is information that controls only its own monitor, the control unit 111 may end the process of this flowchart without proceeding to step st014.

(Step st014) The communication interface 103 displays information acquired by the operation input unit 104 (information including setting information (control information) and target identification information for identifying the display device 10) via the communication output unit 102. Output to device 10 (display device 10 on the downstream side of one of its own display devices 10). This completes the processing of this flowchart.

<Second embodiment>
Next, a second embodiment of the present invention will be described. FIG. 8 is a schematic view showing an outline of the display system 2 according to the second embodiment of the present invention.
In the display system 2 according to the second embodiment, the user can execute the setting change and the like in the display device 10 by the remote controller (hereinafter, referred to as the remote controller 60).

If a remote control light receiving unit is provided on the front surface of each display device 10, it is possible to configure the display device 10 to change settings or the like using the remote control. However, for example, in a monitor having a narrow bezel width, the remote control light receiving unit may not be provided on the front surface of the display device 10. In that case, depending on the installation position of the remote control light receiving unit, a display device 10 that cannot receive the light transmitted from the remote control may occur in the multi-display.

Therefore, in the display system 2 shown in FIG. 8, the remote control light receiving unit 50 is attached only to the display device 10a, which is the most upstream display device. As a result, as in the first embodiment, the setting change in the display device 10 on the downstream side can be executed by operating the operation input unit 104 on the back surface of the display device 10a, which is the most upstream display device. In the display system 2 according to the second embodiment, the setting of the display device 10 on the downstream side is changed via the remote control light receiving unit 50 attached to the display device 10a, which is the most upstream display device, by operating the remote controller 60. Can be executed. That is, the remote controller 60 and the remote controller light receiving unit 50 are examples of the operation input unit 104.

When the remote controller 60 is used as in the display system 2 according to the second embodiment, the remote controller light receiving units (not shown) of all the display devices 10 on the downstream side are set to be invalid. Is desirable.

<Third embodiment>
Next, a third embodiment of the present invention will be described. FIG. 9 is a schematic view showing an outline of the display system 3 according to the third embodiment of the present invention.

As shown in the figure, in the display system 3 according to the third embodiment, the control unit 111 displays a plurality of display devices 10 (10a, 10b, 10c, and 10d in FIG. 9) constituting the display system 3. The displayed image is displayed on the display unit 105 of a specific display device 10 using the OSD, and an image showing the arrangement state of the plurality of display devices 10 is presented to the user. Then, the control unit 111 selects a predetermined one of the plurality of display devices 10 displayed on the display unit 105 of the specific display device 10 based on the operation input from the user. The identification information corresponding to the displayed display device 10 is set as the target identification information.

FIG. 9 shows the display device 10 arranged on the upper left side of the plurality of display devices 10 (10a, 10b, 10c, and 10d) constituting the display system 3, and the identification information of "ID: 3". It is a figure showing the state in which the display device 10b which is the display device 10 associated with is selected.

As described above, the display system 3 according to the third embodiment uses the OSD to display images showing a plurality of display devices 10 (10a, 10b, 10c, and 10d in FIG. 9) constituting the display system 3. Since the display is visually displayed on the display unit 105 of the specific display device 10, the user can more easily select the display device 10 to be controlled such as setting change.

According to the display system 3 according to the third embodiment, even in the case of a multi-display composed of a large number of display devices 10, the user confirms each of the display units 105 of the large number of display devices 10. Since it is only necessary to check the display unit 105 of the specific display device 10 without removing the display device 10, the display device 10 to be controlled such as setting change can be more easily selected.

FIG. 10 is a block diagram showing a basic configuration of a display device 10 of a display system according to the first to third embodiments of the present invention.
As shown in the figure, the display device 10 is a display device constituting a display system having a plurality of display devices 10 connected so as to be communicable, and is a display unit 105 for displaying an image and an operation input for receiving an operation by a user. When the target identification information that specifies the unit 104 and the display device 10 that executes the control information corresponding to the operation is the same as the identification information associated with the own display device 10, processing is performed based on the control information. Communication between the control unit 111 to be executed and when the target identification information is different from the identification information associated with its own display device 10, the control information and the target identification information are output to another connected display device 10. It includes an output unit 102.

As described above, in the display system 1 according to the first embodiment of the present invention, the display system 2 according to the second embodiment, and the display system 3 according to the third embodiment, the setting in the display device 10 Since the setting information (control information) for executing the process such as change may be sequentially transmitted from the most upstream display device 10 to the downstream display device 10 which is communicated and connected in series, the user can use the downstream. It is possible to more easily change the settings of the display device 10 on the side.

In the display system 1 according to the first embodiment of the present invention, the display system 2 according to the second embodiment, and the display system 3 according to the third embodiment, the uppermost stream in which the individual control function is enabled. Display device 10 adds identification information for identifying the display device 10 to be operated to the setting information (control information) based on the operation by the operation input unit 104 or the remote control 60, and transmits the identification information to the display device 10 on the downstream side. .. The display device 10 to be operated executes the setting based on the setting information (control information).

That is, the most upstream display device 10 in which the individual control function is enabled transmits setting information (control information) by adding identification information corresponding to the display device 10 to be operated, and therefore, according to the present invention. Therefore, the determination process for determining which display device 10 is the display device 10 to which the setting information (control information) is transmitted becomes unnecessary.
Further, according to the present invention, the most upstream display device 10 does not need to acquire the setting information (control information) at the time before the setting of the display device 10 to be operated, so that the display on the downstream side is displayed. Processing such as setting change in the device 10 can be executed more easily.

In the above-described embodiment, the information is transmitted only from the display device 10 on the upstream side to the display device 10 on the downstream side, but the communication is not limited to this. In the case of bidirectional communication in which feedback from the display device 10 on the downstream side to the display device 10 on the upstream side is possible, for example, the user operates the operation key of the display device 10 on the most downstream side to display the display. It is possible to change the setting so that the device 10 is the most upstream display device 10 instead of the most downstream one.

Further, in the case of bidirectional communication in which feedback from the display device 10 on the downstream side to the display device 10 on the upstream side is possible, the display device 10 on the upstream side acquires information such as error information from the display device 10 on the downstream side. By doing so, error handling can be performed more reliably.

For example, when the individual control function of the most upstream display device 10 is in the ON state (second mode), the user operates the operation keys of the most downstream display device 10 to individually operate the most downstream display device 10. When the control function is changed to the ON state (second mode), the control information for turning off the individual control function of the most upstream display device 10 (making it the first mode) is the most downstream display device 10. May be transmitted to the most upstream display device 10 in order. This makes it possible to change the display device 10 which was the most downstream to be the most upstream display device 10.

Further, even when the operation keys of the display device 10 located in the middle, which is neither the most upstream nor the most downstream, are operated, information can be transmitted to all the display devices 10 in the case of bidirectional communication. Therefore, it is possible to perform a process of changing the most upstream display device 10 as described above.

A program for realizing all or a part of the functions of the display system 1, the display system 2, the display system 3, or the display device 10 was recorded on a computer-readable recording medium and recorded on the recording medium. The processing of each part may be performed by loading the program into the computer system and executing it. The term "computer system" as used herein includes hardware such as an OS and peripheral devices.
Further, the "computer system" includes a homepage providing environment (or a display environment) if a WWW system is used.
Further, the "computer-readable recording medium" refers to a portable medium such as a flexible disk, a magneto-optical disk, a ROM, or a CD-ROM, or a storage device such as a hard disk built in a computer system. Further, a "computer-readable recording medium" is a communication line for transmitting a program via a network such as the Internet or a communication line such as a telephone line, and dynamically holds the program for a short period of time. In that case, it also includes the one that holds the program for a certain period of time, such as the volatile memory inside the computer system that is the server or client. Further, the above-mentioned program may be a program for realizing a part of the above-mentioned functions, and may be a program for realizing the above-mentioned functions in combination with a program already recorded in the computer system.
