Hereinafter, embodiments of the present invention will be described with reference to the drawings.
<First Embodiment>
FIG. 1 is a schematic diagram showing an overview of a display system 1 according to the first embodiment of the present invention. 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 20b) and a 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 drawing, a display device 10b is arranged side by side above the display device 10a, a display device 10c is arranged next to the display device 10a, and a display device 10d is arranged next to the display device 10b. Thus, 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 diagram illustrating 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 illustrated, 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. 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 of the display device 10b and the display device The communication input unit 101 of 10d is connected for communication by a communication line 40.

  That is, the four display devices 10 are connected in series in the order of the display device 10a, the display device 10c, the display device 10b, and the display device 10d. In this way, by the communication connection of the display device 10, information can be transmitted in order from the display device 10a (the most upstream display device 10) to the display device 10d (the most downstream display device 10).

  In addition, the display apparatus 10 is installed near the wall surface, and it is assumed that the back surface and the wall surface of the display apparatus 10 are installed 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. A setting change (operation input) can be performed by operating the operation input unit 104 by reaching from the lower side of the display device 10a or the display device 10c to the back. However, when it is desired to change the setting of the display device 10b or the display device 10d, the operation input unit 104 of the display device 10b or the display device 10d can be reached even if the hand is reached from the lower side of the display device 10a or the display device 10c. Can not change the settings (operation input) because it is out of reach.

  Therefore, the display system 1 according to the present invention transmits all the display devices by transmitting the setting information (control information) regarding the setting change and the like from the upstream display device 10 to the downstream display device 10 through the communication connection described above. Allows processing such as 10 setting changes.

  In addition, not only the multi-display in which the display device 10 is arranged in 2 rows and 2 columns as in the present embodiment, for example, the same applies to all the multi-displays in which the display device 10 is arranged in 10 rows and 10 columns. 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 a multi-display. A configuration may be employed in which communication connections are made in series between the plurality of display devices 10 using a communication line for transmission. Of course, each display device 10 may be in communication connection with the video signal generation device 20, and each display device 10 may individually acquire a video signal. In addition, the information to be transmitted is configured to transmit the video signal (video information) and the setting information (control information) using separate communication lines. However, such information is transmitted using the same communication line. It may be a configuration.

FIG. 3 is a schematic diagram showing identification information setting 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, identification information is set in advance by the user. The identification information is set using, for example, an OSD (On-Screen Display) function that is a function provided in the display device 10.

  FIG. 3 shows a state in which identification information is set on each display device 10 and each identification information is displayed by the OSD. As illustrated, 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: In other words, the display device 10a, the display device 10b, the display device 10c, and the display device 10d in FIG. 3 are displayed as “1”, “3”, “2”, and “4”, respectively. "(Identifier) is set.

FIG. 4 is a schematic diagram illustrating settings 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, “target monitor: 3” and “individual control: ON” are displayed on the display device 10a. The display “target monitor: 3” is a state in which the monitor to be set by the operation key of the display device 10a is the monitor to which the ID “3” is assigned (that is, the display device 10b). It shows that. In addition, the display of “individual control: ON” is enabled (ON) by a function (individual control function) that can set other display device 10 instead of its own display device 10a by an operation key of the display device 10a. This indicates that the state is (second mode).

  The configuration may be such that the individual control function is 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.

  Thus, 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 upstream display device 10 to display the downstream display. Operations such as changing the settings of the apparatus 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 illustrated, 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. A video signal output unit 107, a video switch 108, a video control unit 109, an output video control unit 110, a control unit 111, an ID control unit 112, a storage unit 113, a cable detection unit 114, It is comprised including.

The communication input unit 101 is identification information for identifying setting information (control information) related to the setting of the display device 10 and the display device 10 to be set from the communication output unit 102 described later of the other connected display device 10. This is an input terminal for acquiring object 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 through 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 a user. For example, 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 are input to the operation input unit 104 based on an 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 displays a video based on a video signal input from the video signal input unit 106a or the video signal input unit 106b, which will be described later, for example, a liquid crystal display (LCD) or an organic EL (electroluminescence) display. It is.

  The video signal input unit 106a and the video signal input unit 106b acquire the video signals transmitted from the video signal generation device 20a and the video signal generation device 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 (to be described later) of the other display device 10 via a communication line that transmits the video signal.

  In the following description, when the video signal input unit 106a and the video signal input unit 106b are not specified, they are 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 generation device 20, and the downstream display device 10 is one upstream of its own display device 10. The video signal output from the video signal output unit 107 of the display device 10 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 through 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. The video switch 108 switches so that one of the video signals input from the video signal input unit 106 a or 106 b is output to the video signal output unit 107. Note that 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 data 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 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 to the ID control unit 112 described later and the storage unit 113 described later. .

  Further, for example, the control unit 111 has its 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, processing such as setting change of its own display device 10 is executed based on the acquired setting information (control information).

  Further, for example, the control unit 111 has its 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. 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 identification information (ID) set in the display device 10. For example, when the identification information set in its own display device 10 and the identification information set in another display device 10 are the same (overlapping), the ID control unit 112 has different identification information. In some cases, various controls for resetting the display device 10 may be performed, and the display device 10 may be simultaneously controlled from the most upstream display device 10 with the same identification information (ID). .

  The storage unit 113 stores various data and programs used for 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 (Electrically Erasable Programmable Read Only Memory), a ROM (Read Only Memory and read only memory A, RAM). / Write Memory; read / write memory), or any combination thereof.

  The cable detection unit 114 detects whether a 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, the display device 10 upstream of the display device 10 does not exist, that is, the display device 10 is the most upstream display device. 10 can be recognized.

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 no cable is connected to the input terminal, or “ID: 1” as identification information. Any method, such as a method of recognizing based on the setting, may be used.
The flowchart shown in FIG. 6 starts when an operation input for setting an operation target monitor is performed by the user in the most upstream display device 10 (monitor (1)).

(Step st001) The operation input unit 104 acquires information based on an operation key operation by the user, and outputs the acquired information to the control unit 111. Thereafter, 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 for turning the individual control function “ON” (second mode) in the information acquired by the operation input unit 104 or a state in which the individual control function is already “ON” ( It is detected whether or not the second mode). When the individual control function is “ON” (second mode), the process proceeds to step st004. If not, 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 determines its own control based on the 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, its own monitor (1) is controlled). Above, the process of this flowchart is complete | finished.

(Step st004) The control unit 111 detects whether 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. Otherwise, the process proceeds to step st006.

  The special key is a pattern of operation keys to be input when the user switches the individual control function to “OFF” (first mode). For example, the special key is determined in advance 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). Above, the process of this flowchart is complete | finished.

(Step st006) The communication interface 103 displays the 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. The data is output to the device 10 (the display device 10 on the downstream side of the display device 10 of its own). Above, the process of this flowchart is complete | finished.

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 downstream display device 10.
The flowchart illustrated 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 the unit 111. Thereafter, the process proceeds to step st012.

(Step st012) The control unit 111 includes identification information (ID) in which the target identification information (ID) included in the information acquired by the communication input unit 101 is classified by the display device 10 stored in the storage unit 113. Whether or not they are the same is detected. If they are the same, the process proceeds to step st013. Otherwise, the process proceeds to step st014.

(Step st013) The control unit 111 executes the process of its own display device 10 based on the setting information (control information) included in the information acquired by the communication input unit 101 (that is, controls its own monitor). . Thereafter, the process proceeds to step st014. When it is known that the acquired information is information for controlling only its own monitor, the control unit 111 may not proceed to step st014 but may end the process of this flowchart.

(Step st014) The communication interface 103 displays the 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. The data is output to the device 10 (the display device 10 on the downstream side of the display device 10 of its own). Above, the process of this flowchart is complete | finished.

<Second Embodiment>
Next, a second embodiment of the present invention will be described. FIG. 8 is a schematic diagram showing an overview of the display system 2 according to the second embodiment of the present invention.
In the display system 2 according to the second embodiment, a user can execute a setting change or the like in the display device 10 using a remote controller (hereinafter referred to as a 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 perform a setting change or the like in each display device 10 using the remote control. However, for example, the remote control light receiving unit may not be provided on the front surface of the display device 10 like a monitor with a narrow bezel width. In that case, depending on the installation position of the remote control light receiving unit, in the multi-display, the display device 10 that cannot receive the light transmitted from the remote control may occur.

  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. Thus, similarly to the first embodiment in which setting change or the like in the downstream display device 10 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, by operating the remote controller 60, setting changes in the downstream display device 10 are performed via the remote control light receiving unit 50 attached to the display device 10a which is the most upstream display device. Can be executed. That is, the remote control 60 and the remote control light receiving unit 50 are examples of the operation input unit 104.

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

An image to be displayed is displayed on the display unit 105 of the specific display device 10 using the OSD, and an image representing the arrangement state of the plurality of display devices 10 is presented to the user. Then, the control unit 111 selects a predetermined display device 10 among a plurality of display devices 10 displayed on the display unit 105 of the specific display device 10 based on an 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 among the plurality of display devices 10 (10a, 10b, 10c, and 10d) constituting the display system 3, and identification information “ID: 3”. It is the figure showing the state as which the display apparatus 10b which is the display apparatus 10 matched with is selected.

  As described above, the display system 3 according to the third embodiment uses an OSD to display an image showing a plurality of display devices 10 (10a, 10b, 10c, and 10d in FIG. 9) constituting the display system 3. Since it is visually displayed on the display unit 105 of the specific display device 10, the user can more easily select the display device 10 that is desired 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 configured by a large number of display devices 10, the user confirms the display units 105 of the large number of display devices 10, respectively. Since it is only necessary to confirm only the display unit 105 of the specific display device 10 without performing the selection, it is possible to more easily select the display device 10 that is desired to be controlled such as setting change.

FIG. 10 is a block diagram showing a basic configuration of the display device 10 of the 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 that constitutes a display system having a plurality of display devices 10 that are communicably connected to each other, and includes a display unit 105 that displays an image and an operation input that receives an operation by a user. When the target identification information that designates the display device 10 that executes the control information corresponding to the operation of the unit 104 and the operation is the same as the identification information associated with the display device 10 of its own, the processing is performed based on the control information. Communication for outputting the control information and the target identification information to another connected display device 10 when the control unit 111 to be executed and the target identification information are different from the identification information associated with its own display device 10 And 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 is performed. Since the setting information (control information) for executing processing such as change may be transmitted in order from the most upstream display device 10 to the downstream display device 10 connected in series, the user can A setting change or the like in the display device 10 on the side can be performed more easily.

The display device 10 that is the operation target executes setting based on the setting information (control information).

That is, the most upstream display device 10 in which the individual control function is enabled adds identification information corresponding to the display device 10 to be operated and transmits setting information (control information). According to this, a determination process for determining which display device 10 is the display device 10 to which the setting information (control information) is transmitted becomes unnecessary.
In addition, according to the present invention, the most upstream display device 10 does not need to obtain the setting information (control information) at the time before the setting of the display device 10 to be operated in advance. Processing such as setting change in the apparatus 10 can be executed more easily.

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

  Further, in the case of bidirectional communication in which feedback from the downstream display device 10 to the upstream display device 10 is possible, the upstream display device 10 acquires information such as error information from the downstream display device 10. By doing so, error processing 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 key of the most downstream display device 10 to individually select 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 (to enter the first mode) is the most downstream display device 10. To the most upstream display device 10 in order. Accordingly, it is possible to change the display device 10 that has been the most downstream to be the most upstream display device 10.

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

A program for realizing all or part of the functions of display system 1, display system 2, display system 3, or display device 10 is recorded on a computer-readable recording medium and recorded on the recording medium. Processing of each unit may be performed by causing a computer system to read and execute the program. Here, the “computer system” includes an OS and hardware such as peripheral devices.
Further, the “computer system” includes a homepage providing environment (or display environment) if a WWW system is used.
The “computer-readable recording medium” refers to a storage device such as a flexible medium, a magneto-optical disk, a portable medium such as a ROM and a CD-ROM, and a hard disk incorporated in a computer system. Furthermore, the “computer-readable recording medium” dynamically holds a program for a short time like a communication line when transmitting a program via a network such as the Internet or a communication line such as a telephone line. In this case, a volatile memory in a computer system serving as a server or a client in that case, and a program that holds a program for a certain period of time are also included. The program may be a program for realizing a part of the functions described above, and may be a program capable of realizing the functions described above in combination with a program already recorded in a computer system.

  The embodiment of the present invention has been described in detail with reference to the drawings. However, the specific configuration is not limited to this embodiment, and includes design changes and the like without departing from the gist of the present invention.
