  However, in the technique of Patent Document 1, the wireless communication unit of the display device wirelessly communicates with the arrangement position information setting unit attached to the stand unit, so that the display device can receive the number of horizontal monitors from the arrangement position information setting unit. Since the number of vertical monitors and the monitor setting number are taken in to determine their own arrangement position in the multi-monitor system, the arrangement position of the display device cannot be set in advance. In such a display device, there are individual differences in luminance and / or color reproducibility, and the arrangement position may be determined according to the individual difference. However, with the technique of Patent Document 1, the arrangement position cannot be set in advance. For this reason, there is a problem that it is difficult to notice even if the display device is attached to different positions of the stand unit.

  In this regard, in the technique of Patent Document 2, since the arrangement position of each display device is set in advance and the set arrangement position is stored, the arrangement position according to the individual difference of each display device can be set. However, the set arrangement position is only stored in the storage unit. For this reason, the person who installs the multi-screen display and the user who uses the multi-screen display actually display an image or video after installing the multi-screen display as to whether or not each display device is installed in the correct position. I don't know unless I try. This is inconvenient.

  Therefore, a main object of the present invention is to provide a novel display device, display control program, and display control method.

<First embodiment>
FIG. 1 is a block diagram showing an electrical configuration of a display device 10 according to a first embodiment of the present invention. Referring to FIG. 1, the display device 10 includes a CPU 30, and the CPU 30 is connected to a RAM 34, an EEPROM 36, a communication unit 38, a display drive unit 40, a video signal input unit 44, an operation unit 46, and a power supply control via a bus 32. Connected to the unit 48. In addition, a display unit 42 is connected to the display driving unit 40.

  The CPU 30 governs overall control of the display device 10. The RAM 34 is used as a work area and a buffer area for the CPU 30. The EEPROM 36 is a non-volatile memory such as an EEPROM, and stores a control program for controlling the display device 10 and data on various types of information on the display device 10. However, in place of the EEPROM 36, other nonvolatile memory such as flash memory or HDD may be provided.

  The communication unit 38 is an interface for communicating with a USB memory or another computer, for example, a wired LAN, RS-232C, USB, DDC / CI (Display Data Channel Command Interface), HDMI-CEC (High Definition Multimedia Interface). Consumer Electronics Control) can be used.

  However, the other computer means the PC 102 or another computer or another display device 10.

  In the multi-display system (network system) 100 shown in FIG. 2 described later, the plurality of display devices 10 are connected to the PC 102 via the hub 104, but the plurality of display devices 10 are daisy chain connected. May be. In such a case, the communication unit 38 is provided with an input port and an output port.

  As another example, the communication unit 38 may be realized by a wireless LAN.

  The display driving unit 40 is a controller for generating and outputting a video or an image displayed on the display unit 42. The display unit 42 includes a display panel and a backlight, and outputs data about the video or image provided from the display driving unit 40.

  The video signal input unit 44 is an interface for inputting data about video or images given from another computer, and uses DisplayPort, HDMI (registered trademark), DVI, D-SUB, and the like. However, not only video or image data but also audio data can be input.

  The operation unit 46 is a variety of operation buttons (operation keys) and a remote control receiver provided on the display device 10, and accepts an operation input by a user or transmits a remote control signal (infrared signal) transmitted from a remote control (not shown). Or receive. For example, the operation unit 46 is used when the power of the display device 10 is turned on or various information about the display device 10 is set and changed (adjusted). Various types of information correspond to brightness, brightness, contrast, color temperature, horizontal position, vertical position, and the like.

  The power control unit 48 is a circuit (switch circuit) for supplying and stopping power (voltage) to each component under the instruction of the CPU 30. Although illustration is omitted, the power supply control unit 48 is applied with a DC voltage (DC power supply) in which an AC voltage from a commercial power supply is appropriately stepped down and rectified (noise removed).

  FIG. 2 is a block diagram showing an example of a multi-display system (hereinafter simply referred to as “system”) 100 configured using a plurality of display devices 10 shown in FIG.

  As shown in FIG. 2, the system 100 includes a PC 102, and the PC 102 is communicably connected to each of the plurality of display devices 10 via a hub 104. For example, each of the PC 102 and the plurality of display devices 10 is connected to the hub 104 using a LAN cable. However, the PC 102 may be communicably connected to each of the plurality of display devices 10 via a wireless LAN. Alternatively, the plurality of display devices 10 may be daisy chain connected, and the display device 10 disposed at one or the other end may be directly connected to the PC 102 by a wired LAN or a wireless LAN.

  In the case of configuring a multi-display in such a system 100, first, the arrangement of the multi-display is determined. Next, the arrangement position of each of the plurality of display devices 10 used in the multi-display is determined by a developer or a designer. This is because there is an individual difference (variation) in luminance or / and color among the plurality of display devices 10. Therefore, for example, when the arrangement position of each of the plurality of display devices 10 used in the multi-display is determined, information describing the determined arrangement position in association with the serial number of each display device 10 is Given to the person installing the display. The person in charge of installation installs the multi-display (each display device 10) according to the information describing the determined arrangement position.

  Usually, the information describing the arrangement position is a table data or a paper medium on which the table data is printed, and the person in charge of installation opens each of the packed display devices 10 and attaches it to each display device 10. The serial number is confirmed by looking at the label, and each display device 10 is installed according to the information describing the arrangement position.

  For this reason, each display device 10 may be placed in a standby position in an unsealed state until it is fixed to a frame for constituting a multi-display, so that the display surface of the display unit 42 (display panel) Inconveniences such as scratches may occur.

  For example, when a multi-display having a 5 × 5 array is installed so that its display surface is perpendicular or substantially perpendicular to a horizontal plane (floor surface or ground), the display device 10 of the uppermost stage is arranged. The height may exceed 4m. For this reason, in particular, with respect to the uppermost display device 10, it is difficult to visually confirm the label on which the serial number is written. Therefore, it is impossible to confirm whether or not each display device 10 is arranged (installed) at a correct arrangement position until an image or video is actually displayed.

  In order to avoid such inconvenience, in the first embodiment, various information such as an RGB contrast value, a brightness adjustment value, and an input mode (image or video input interface) for reducing the color difference on the display surface are set. In addition, the information on the arrangement position and the arrangement direction in the multi-display is set in advance for each display device 10, and it is easy even before the packaged display device 10 is opened and after it is arranged at the arrangement position. The arrangement position can be confirmed.

  In the first embodiment, the display device 10 has a function of executing processing (operation) according to a predetermined command (command written in text) from another computer. However, some commands may be transmitted from a USB memory attached to the display device 10.

  In the first embodiment, the predetermined commands are a power-on instruction command, an installation information designation command, and a display information setting command. The predetermined command includes commands for setting various information such as the RGB contrast value, the brightness adjustment value, and the input mode, but these commands are different from the essential contents of the present invention. The description will be omitted in this specification.

  The power-on instruction command is a command for turning on the power of the display device 10. When receiving the power-on command, the display device 10 turns on its own power according to the command. However, the display device 10 may turn on its own power in response to the operation of the power button included in the operation unit 46.

  In the first embodiment, the installation information designation command sets position information indicating the arrangement position on the multi-display 50 and installation direction information indicating the arrangement direction (direction for designating the side surface serving as the top surface) on the display device 10. It is a command to make it. Upon receiving the installation information designation command, the display device 10 sets position information and installation direction information (hereinafter, these may be collectively referred to as “installation information”) according to the command. That is, in accordance with the installation information designation command, the display device 10 stores the position information and the installation direction information described in the command in a nonvolatile memory (in the first embodiment, the EEPROM 36).

  In this first embodiment, the display information setting command sets information on the direction of an arrow (arrow direction information) that indicates the side surface to be the top surface, and sets restriction information for restricting the display of installation information. It is a command to do. Upon receiving the display information setting command, the display device 10 determines the direction of the arrow from the installation direction information according to the command, stores the arrow direction information in the EEPROM 36, and stores the restriction information described in the command in the EEPROM 36. To remember. In the first embodiment, the restriction information includes information on the remaining display count (maximum display count) and display deadline (year / month / day and time). However, the installation direction information is stored in the EEPROM 36 in accordance with the installation information designation command as described above.

  After the installation information, the arrow direction information, and the restriction information are set, when the display device 10 is turned on, the display unit 42 (display panel) of the display device 10 displays the installation information on the multi-display 50, That is, position information and arrangement direction information (arrow direction information) are displayed.

  As described above, the restriction information is set when the multi-display 50 is introduced, and the position information and the arrow indicating the side to be the top surface are displayed on the display device 10 (display unit 42). This is because it should not be displayed after 50 is installed.

  FIG. 3 is an illustrative view showing an example of a multi-display 50 configured using nine display devices 10 in the system 100 shown in FIG. However, in FIG. 3, the PC 102, the hub 104, and the like are omitted.

  As shown in FIG. 3, in the multi-display 50, nine display devices 10 are arranged three by three in the vertical direction and the horizontal direction, respectively. That is, the array of the nine display devices 10 is 3 × 3.

  When the multi-display 50 having such an arrangement is viewed from the front, if the position information of each display device 10 is expressed by row and column elements as in the matrix, in the example shown in FIG. ) Is set to (1, 1). Further, the position information of the display device 10 arranged in the upper middle is set to (1, 2). Further, the position information of the display device 10 arranged on the upper right (upper right) is set to (1, 3).

  The position information of the display device 10 arranged on the left in the middle row is set to (2, 1). Further, the position information of the display device 10 arranged in the middle of the middle stage is set to (2, 2). Further, the position information of the display device 10 arranged on the right in the middle stage is set to (2, 3).

  The position information of the display device 10 arranged in the lower left (lower left) is set to (3, 1). The position information of the display device 10 arranged in the middle of the lower stage is set to (3, 2). Further, the position information of the display device 10 arranged in the lower right (lower right) is set to (3, 3).

  Thus, according to the matrix, the position information set in each display device 10 increases as the number of rows goes from top to bottom, and the number of columns increases from left to right. That is, each of the number of rows and the number of columns increases as it goes in a certain direction. Hereinafter, in this specification, position information is set so that each of the number of rows and the number of columns increases toward a certain direction for the plurality of display devices 10 whose arrangement positions are determined in the multi-display 50. This method is called arrangement pattern 1.

  In the first embodiment, when the multi-display 50 in which nine display devices 10 are arranged in 3 × 3 is viewed from the front, the position information of each display device 10 is set similarly to the matrix. However, it need not be limited to this. This is because the direction in which the arranged multi-displays 50 are viewed is not always constant, and the arrangement order of the position information set in each display device 10 is not always constant.

  For example, when the multi-display 50 shown in FIG. 3 is viewed from the left side, the position information of each display device 10 is set by rotating the 3 × 3 matrix 90 degrees clockwise (clockwise). In this case, the display device 10 at the upper right in FIG. 3 is arranged at a position (hereinafter referred to as a start position) where (1, 1) is set as position information. In addition, according to the arrangement pattern 1, the position information of the other display devices 10 is set so that the number of rows increases from the right to the left, and the number of columns increases from the top to the bottom. Set to

  Further, the arrangement pattern of the plurality of display devices 10 whose arrangement positions are determined in the multi-display 50 need not be limited to the arrangement pattern 1. For example, the number of rows may be increased according to a certain direction, and the direction of increasing the number of columns may be switched for each column. In such a case, the position information of the three display devices 10 arranged in the middle stage of the multi-display 50 shown in FIG. 3 is (2, 1), (2, 2), from right to left. Set to (2, 3). Hereinafter, in this specification, a method of setting position information so that the number of rows is increased in a certain direction and the direction in which the number of columns is increased is replaced for each column will be referred to as an arrangement pattern 2.

  Furthermore, the left and right directions of the arrangement pattern 1 and the arrangement pattern 2 may be reversed. In arrangement pattern 1 and arrangement pattern 2, even if the left and right directions are reversed, the direction in which the number of rows increases does not change, but the direction in which the number of columns increases is opposite in each row. Hereinafter, in this specification, the directions of the arrangement pattern 1 and the arrangement pattern 2 are referred to as a clockwise direction (clockwise direction) when the number of columns increases from the left to the right from the start position. A case where the number increases as it goes from right to left is called a counterclockwise (counterclockwise) direction.

  Therefore, when the designer or developer of the multi-display 50 determines the arrangement (size) of the multi-display 50 and determines the arrangement position of each display device 10 used in the multi-display 50, the start position, the arrangement pattern, and the arrangement pattern are determined. The position information of each display device 10 is set.

  Here, explanation about the direction in which each display device 10 is installed is omitted, but each display device 10 is not only arranged, but among the four side surfaces, when the multi-display 50 is viewed from the front, The side surface (top surface) is also determined.

  In the example of the multi-display 50 shown in FIG. 3, a character string indicating its own position information (arrangement position) is displayed on the display unit 42 of each display device 10, and among the side surfaces of the display device 10, An arrow indicating the direction indicating the side surface to be the top surface is displayed. However, as can be seen from FIG. 3, the character string indicating the position information of the display device 10 is displayed at the center or almost the center of the display surface of the display unit 42 and at two places on the top thereof. In this first embodiment, a character string (hereinafter sometimes referred to as “first character string”) 60 indicating position information displayed at the center or substantially at the center is displayed at the top thereof. Is larger than a character string 62 (hereinafter sometimes referred to as “second character string” for convenience of description) 62 (see FIG. 4C). This is because the roles of the first character string 60 and the second character string 62 are different. In addition, an arrow 64 indicating the direction indicating the side surface to be the top surface is displayed in the vicinity of the second character string 62 (see FIG. 4C).

  For example, after the multi-display 50 is installed, the first character string 60 has a role of allowing an installation person or the like to check whether or not each display device 10 constituting the multi-display 50 is arranged at a correct arrangement position. . In addition, the second character string 62 and the arrow 64 indicate, for example, an installation person or the like instructing an arrangement position at which each display device 10 should be arranged and a side surface serving as a top surface before each display device 10 is installed. It has a role to make it confirm. However, since the second character string 62 can be viewed even after the multi-display 50 is set, the second character string 62 also plays the same role as the first character string 60.

  4A is an illustrative view of an example of the packaging box 200 of the display device 10 as viewed from the front, and FIG. 4B is an illustrative view of an example of the packaging box 200 of the display device 10 as viewed from the back. FIG. 4C is an illustrative view for explaining a display example of the display device 10 and a direction instructing a side surface to be a top surface. However, in FIGS. 4A and 4B, it is assumed that the display device 10 is in the packing box 200.

  Although detailed description is omitted, for example, the packaging box 200 is formed of cardboard, and the display device 10 is cured on the display surface of the display unit 42 (display panel) and enclosed in the packaging box 200 using a cushioning material. (Packed).

  As shown in FIG. 4A, an opening 200a is provided on the front surface (front surface) of the packaging box 200. As shown in FIG. 4C, the opening 200a is formed corresponding to the position or range where the second character string 62 and the arrow 64 are displayed. Therefore, the position or range where the second character string 62 and the arrow 64 are displayed is the same in each display device 10, and the direction of each display device 10 when packed in the packing box 200 is constant. However, the opening 200a may be closed until the display device 10 is transported to the installation location. This is to prevent inconveniences such as the display device 10 being damaged during transportation. The same applies to the opening 200b described later.

  Further, as shown in FIG. 4B, an opening 200b is provided on the back surface (back surface) of the packaging box 200. The opening 200 b is provided to supply power to the display device 10 in the packaging box 200 and to transmit a command to the display device 10. Therefore, the opening 200b is formed corresponding to the position where the terminal connected to the power cable and the communication unit 38 of the display device 10 is provided.

  However, when setting the above-mentioned various information, position information, arrangement direction information, and restriction information for each of the plurality of display devices 10 used in the multi-display 50, it is only necessary to connect another computer individually. When setting these pieces of information, there is no need to configure the system 100 as shown in FIG.

  Thus, since the opening 200a and the opening 200b are provided, the designation of the installation information and the setting of the display information are performed not only before or after the display device 10 is packaged but also in a packaged state. Can do.

  In the case shown in FIG. 11B, as shown in FIG. 12B, the display device 10 at the position “3” starts from the display pattern 10 according to the arrangement pattern 2 (the order according to the arrows in the drawing). The delay time is set to 0 seconds, 1 second,..., 8 seconds until the display device 10 at the position “7”.

  Although illustration is omitted, the delay time is similarly set in other cases.

  In the second embodiment, the delay time (PONDLY) is calculated according to Equation 1. In Equation 1, M_SIZE_X is the number (total number) of display devices 10 arranged in the horizontal direction when the multi-display 50 actually installed is viewed from the front. M_POS_x is a horizontal arrangement position (the number of columns) of the display device 10 that is a target for calculating the delay time when the multi-display 50 that is actually installed is viewed from the front. Specifically, This is the number indicated by the element on the right side of the position information of the display device 10. Further, M_POS_y is a vertical arrangement position (number of rows) of the display device 10 that is a target for calculating the delay time when the multi-display 50 that is actually installed is viewed from the front. Specifically, This is the number indicated by the element on the left side of the position information of the display device 10. Further, T is a delay time from when the display unit 42 of the immediately preceding display device 10 is turned on to when the display unit 42 of its own display device 10 is turned on in the order according to the arrangement pattern 1 or 2. In the embodiment, it is set to 1 second.

[Equation 1]
PONDLY = {(M_POS_x-1) + (M_POS_y-1) × M_SIZE_X} × T
Accordingly, in the example shown in FIG. 12A, the delay time of the display device 10 at the position “5” is calculated as shown in Equation 2 when Equation 1 is used. However, the position information of the display device 10 at the position “5” is (2, 1).

[Equation 2]
PONDLY4 = {(1-1) + (2-1) × 3} × 1 = 3
As described above, in the second embodiment, since the delay time is calculated for each display device 10, the setting information designation command includes information on the arrangement (size) of the multi-display 50 as the installation information. . However, this arrangement is an arrangement (the number of display devices 10 in the vertical direction × the number of display devices 10 in the horizontal direction) when the actually installed multi-display 50 is viewed from the front. Information about whether to execute the power-on delay is included in the display information setting command. Therefore, in the second embodiment, as shown in FIG. 13, the display control program is a program for setting a delay time (power on delay time) in accordance with a display information setting command (power on delay setting program). 302h is further included. The power-on delay setting program 302h calculates delay time information and turns on a delay flag 304i described later. However, data (delay time information data) 304 h regarding the calculated delay time information is stored in a nonvolatile memory such as the EEPROM 36, read out from the EEPROM 36 as necessary, and stored in the RAM 34.

  The data storage area 304 further stores delay time information data 304h, and is provided with a delay flag 304i and a timer 304j. The delay time information data 304 h is data indicating the delay time information described above, and is read from the EEPROM 36 and stored in the RAM 34. The delay flag 304i is a flag for determining whether or not to execute power-on delay, and is turned on when delay time information is set, and when the delay time information is not set or a person in charge of setting It is turned off according to an instruction (command). The timer 304j is a timer for counting the delay time, and starts counting when the activation process is started.

  FIG. 14 is a flowchart showing the startup process of the CPU 30 in the second embodiment. The startup process of the second embodiment is the same as that of the first embodiment except that the processes of steps S101, S103, and S105 are provided before step S1 in the startup process of the first embodiment shown in FIG. Is the same as the activation process. However, in the second embodiment, the delay time information is read from the EEPROM 36 when the power of the display device 10 is turned on. Although illustration is omitted, in the second embodiment, the display drive unit 40 displays the display unit under the instruction of the CPU 30 until the delay time elapses, unless the delay time information is stored. The backlight of 42 is turned off. However, instead of the display drive unit 40 turning off the backlight of the display unit 42, under the instruction of the CPU 30, the power supply control unit 48 supplies power to the backlight of the display unit 42 until the delay time elapses. It may not be supplied.

  As shown in FIG. 14, when starting the activation process, the CPU 30 determines whether or not the delay flag 304i is on in step S101. That is, it is determined whether to perform power-on delay. If “NO” in the step S101, that is, if the delay flag 304i is turned off, the process proceeds to a step S1 as it is.

  On the other hand, if “YES” in the step S101, that is, if the delay flag 304i is turned on, it is determined whether or not a delay time has elapsed in a step S103. In this step S103, the CPU 30 determines whether or not the count value of the timer 304j is equal to or longer than the delay time. However, the timer 304j starts counting when starting processing is started or when “YES” is determined in the step S101.

  If “NO” in the step S103, that is, if the delay time has not elapsed, the process returns to the same step S103. On the other hand, if “YES” in the step S103, that is, if the delay time has elapsed, the backlight is turned on in a step S105, and the process proceeds to the step S1.

  FIG. 15 is a flowchart showing installation information setting processing of the CPU 30 in the second embodiment. The installation information setting process of the second embodiment is the same except that step S111 is provided before the process of step S31 in the first embodiment shown in FIG.

  As shown in FIG. 15, when the CPU 30 starts the installation information setting process in response to the installation information designation command, in step S111, the CPU 36 stores the arrangement information (size) of the multi-display 50 designated by the designation command in the EEPROM 36. The process proceeds to step S31.

  FIG. 16 is a flowchart showing the power-on delay setting process of the CPU 30 in the second embodiment. The power-on delay setting process is executed in advance in accordance with an instruction from the user, whereby the power-on delay is executed in the startup process shown in FIG.

  When a display information setting command including information indicating that the power-on delay is executed is transmitted from another computer, the display device 10 (CPU 30) receives the setting command, and in response thereto, as shown in FIG. The power-on delay setting process is started. However, as described above, since the display information setting process is also executed in accordance with the display information setting command, the power-on delay setting process is executed in parallel with the display information setting process.

  When starting the power-on delay setting process, the CPU 30 determines whether or not the array information and the position information have been acquired in step S71. Here, the CPU 30 determines whether the array information and the position information are stored in the EEPROM 36.

  If “NO” in the step S71, that is, if at least one of the arrangement information and the position information is not acquired, the delay time is set to 0 seconds in the step S79, and the set delay time is stored in the EEPROM 36. Proceed to step S81.

  On the other hand, if “YES” in the step S71, that is, if the array information and the position information have been acquired, the array information and the position information are read in a step S73, and the delay time is calculated according to the equation 1 in a step S75. In the subsequent step S77, the calculated delay time is stored in the EEPROM 36, and the process proceeds to step S81.

  In step S81, the delay flag 304i stored in the EEPROM 36 is set to ON, and the power-on delay setting process is terminated.

  According to the second embodiment, since the time for turning on the display device 10 is delayed, for example, the display units 42 of the plurality of display devices 10 constituting the multi-display 50 are arranged in the order according to the arrangement pattern 1 or the arrangement pattern 2. Can be turned on. Therefore, it is possible to determine whether or not the display device 10 is arranged at a correct arrangement position based on not only the displayed position information but also the turn-on order.

  Further, according to the second embodiment, since the plurality of display devices 10 are not all turned on at a time, it is possible to avoid inconveniences such as a breaker falling due to a sudden increase in the power to be supplied. it can.

  In the second embodiment, the delay time is calculated from the position information. However, the designer of the multi-display 50 may set the delay time according to the position information.

  For example, the delay time of each display device 10 can be determined using a determination screen 400 as shown in FIG.

  When the program for determining the delay time is executed on an arbitrary computer, a determination screen 400 shown in FIG. 17 is displayed on a monitor connected to the computer. The decision screen 400 displays a menu 402 for selecting an arrangement pattern, a menu 404 for selecting a start position, and a menu 406 for selecting a direction, and the display unit 42 of each display device 10 is turned on. A panel image 408 indicating the order in which images are displayed is displayed. On the determination screen 400, a button 410 and a button 412 are displayed below the panel image 408. However, the numbers displayed on each panel of the panel image 408 indicate the order in which the display unit 42 of the display device 10 is turned on.

  For example, after determining position information for each display device 10 arranged at the reference arrangement position, the developer or the like selects an arrangement pattern, a start position, and a direction from the menus 402, 404, and 406 according to the arrangement. Then, the panel images 408 are rearranged in the order in which the display unit 42 is turned on according to the selected arrangement pattern, start position, and direction. Here, when the button 410 is turned on, the delay time of each display device 10 arranged according to the reference arrangement position is determined so that the display unit 42 is turned on in the order indicated by the panel image 408. However, the delay time is set in advance.

In the example shown in FIG. 17, the delay time of the display device 10 arranged at the position “9” is determined as 0 seconds at the reference arrangement position, and the delay time of the display device 10 arranged at the position “6” is determined. Is determined as 1 second, the delay time of the display device 10 arranged at the position “3” is determined as 2 seconds, and the delay time of the display device 10 arranged at the position “8” is determined as 3 seconds. , The delay time of the display device 10 disposed at the position “5” is determined to be 4 seconds, the delay time of the display device 10 disposed at the position “2” is determined to be 5 seconds, and the position “7” is determined. The delay time of the display device 10 arranged at 6 is determined to be 6 seconds, the delay time of the display device 10 arranged at the position “4” is determined to 7 seconds, and is arranged at the position “1”. The delay time of the display device 10 is determined to be 8 seconds.
<Third embodiment>
The display device 10 of the third embodiment not only displays position information and arrangement direction information, but also displays the background in a color (display color) determined according to the position information. Since it is the same as the display device 10 of the example, a duplicate description will be omitted or will be described briefly. The same applies to the same contents already described in the second embodiment.

  In the third embodiment, by changing the display color of the background in each of the plurality of display devices 10 constituting the multi-display 50, it is possible to confirm whether or not the arrangement position of each display device 10 is correct by this change. it can.

  For example, the display color is gradually changed according to a predetermined order, or the luminance is changed according to the predetermined order. In this embodiment, the display color is changed according to the order in which the display devices 10 are arranged. In this embodiment, the display color (RGB) is calculated according to Equation 3 using the array information and the position information. However, M_SIZE_Y is the number (total number) of the display devices 10 arranged in the vertical direction when the actually installed multi-display 50 is viewed from the front.

[Equation 3]
R = 255-M_POS_y ÷ M_SIZE_Y × 200
G = 255- (M_POS_x-1) ÷ M_SIZE_X × 200
B = 255
However, this is merely an example, and the luminance may be simply changed as described above. In the third embodiment, the display color is calculated, but a predetermined color may be set according to a predetermined order.

  In the third embodiment, since the background display color is calculated, the installation information designation command includes the arrangement information (size) of the multi-display 50 as described in the second embodiment. The display information setting command includes an instruction to set the display color.

  Therefore, in the third embodiment, as shown in FIG. 18, the display control program further includes a program (display color setting program) 302j for setting the display color. The display color setting program 302j calculates a display color and stores data (display color information data) 304k about the calculated display color in a nonvolatile memory such as the EEPROM 36. The display color information data 304k stored in the EEPROM 36 is read from the EEPROM 36 as necessary and stored in the RAM 34.

  The data storage area 304 further stores display color information data 304k. The display color information data 304k is data indicating the display color information described above, and is read from the EEPROM 36 and stored in the RAM 34.

  FIG. 19 is a flowchart showing the startup process of the CPU 30 in the third embodiment. The activation process of the third embodiment is the same as the activation process of the first embodiment, except that the processes of steps S7 and S11 are changed in the activation process of the first embodiment shown in FIG. However, in the third embodiment, display color information is read from the EEPROM 36 when the power of the display device 10 is turned on.

  As shown in FIG. 19, if “YES” in the step S5, the position information, the arrow direction information, and the display color information are read in a step S7a, and the remaining display count is subtracted by 1 in a step S9. In S11a, the display driving unit 40 is controlled to display the arrangement position indicated by the position information, the arrow corresponding to the arrow direction information, and the display color background indicated by the display color information on the display unit 42, and start processing is performed. finish.

  FIG. 20 is a flowchart showing display information setting processing in the third embodiment. However, in the third embodiment, it is assumed that the same processing as the installation information setting processing of the second embodiment shown in FIG. 15 is executed in advance.

  In the display information setting process of the third embodiment, the processes of steps S121, S123, and S125 are executed between steps S51 and S53 in the display setting process of the first embodiment shown in FIG. Other than the above, the display information setting process of the first embodiment is the same.

  As shown in FIG. 20, when installation orientation information is read in step S51, arrangement information and position information are read in step S121. In the next step S123, the display color is calculated according to Equation 3 using the read array information and position information. In step S125, the calculated display color information is set, and the process proceeds to step S53. In step S125, the CPU 30 stores the display color information data 304k in the EEPROM 36.

  According to the third embodiment, when the position information is displayed on the display device 10, the display color of the background is made different among the display devices 10. For example, a plurality of display devices 10 constituting the multi-display 50 are provided. The display color can be changed according to the arrangement order. Therefore, it is possible to determine whether or not the display device 10 is arranged at the correct arrangement position based on not only the displayed position information but also a change in display color.

  The modification of the second embodiment and the modification of the third embodiment can be adopted at the same time. In this case, in the start-up process shown in FIG. 19 of the third embodiment, steps S101 to S105 shown in FIG. 14 are executed before step S1. In the third embodiment, the installation information setting process shown in FIG. 15 is executed, and the power-on display setting process shown in FIG. 16 is executed.

  The screens and specific numerical values given in the above-described embodiments are examples, and can be appropriately changed according to the actual product. Moreover, when the same effect is acquired, the order of each step shown to the flowchart may be changed suitably.
