Technical Field

[0001] The present invention relates to a control device and a display control method for setting screen display. Background Art

[0002] When supplying screen display data to a display device, it is necessary to supply screen display data that matches the type of the display device. Patent Document 1 discloses a display device that, if it receives a display signal sent from an information processing device, displays the image of the display signal and generates status information indicating the display state of the image, and notifies the generated status information to the information processing device. The information processing device that receives the status information from the display device, accordingly to the status information, maintains the currently sent display signal when the display signal is suitable for the display device, and generates a new display signal when the display signal is not suitable for the display device. In the technology disclosed in Patent Document 1, a circuit for generating status information indicating the display state in the display device and notifying it to the information processing device is added, whereby a display signal that matches the display device can be supplied.

[0003] Patent Document 1: Japanese Patent Application Laid-Open No. 2012-054700 Summary of the Invention

[0004] However, according to the above prior art, there is a problem that a circuit for generating status information indicating the display state and notifying it to the information processing device needs to be additionally provided in the display device, and the device structure becomes very complicated for performing setting operations that are not necessarily frequent.

[0005] In addition, when performing a setting operation of a display device by a numerical control device, various setting data are sometimes required. Therefore, conventionally, when performing a setting operation from the numerical control device to the display device, dedicated cables different for each display device are required, corresponding to different scanning directions and driving methods for each display device.

[0006] The present invention has been made in view of the above circumstances, and an object thereof is to obtain a control device that does not complicate the device structure and can perform setting of screen display without the need for dedicated cables even when various setting data are required.

[0007] In order to solve the above problems and achieve the object, the control device according to the present invention is characterized by having: a setting data storage unit that stores a plurality of setting data, the setting data including at least one of a scanning direction when a display device displays screen display data, a driving method of the display device, and a transmission timing of the screen display data, and a resolution of the display device, and indicating setting conditions when supplying the screen display data to the display device; and

[0008] A control unit that sequentially sends multiple screen display data corresponding to multiple sets of setting data to a connected display device, causes a message screen that prompts an operator to perform a predefined operation when receiving the screen display data suitable for the connected display device to be displayed on the connected display device, and performs a setting process of selecting the setting data to be used based on the operation information for the message screen.

[0009] Effects of the Invention

[0010] The control device according to the present invention has the following effects: without complicating the device structure, even when various setting data are required, no dedicated cable is needed, and the setting of screen display can be performed. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Hereinafter, the control device and the display control method according to the embodiments of the present invention will be described in detail based on the drawings. In addition, the technical scope of the present invention is not limited by the embodiments shown below

[0028] Embodiment 1.

[0029] Figure 1 It is a diagram showing the structure of the display control system 100 according to Embodiment 1. The display control system 100 includes a control device 1 and a display device 2

[0030] The control device 1 includes a storage device 11, an arithmetic device 12, and an input / output interface section 13. The control device 1 is connected to the display device 2 via a transmission line, and supplies the screen display data for display by the connected display device 2 to the display device 2. The control device 1 can be, for example, a numerical control device

[0031] The storage device 11 has a set data storage unit 111, which has the function of storing information used by the control device 1. The set data storage unit 111 stores a plurality of set data that are different for each type of the display device 2. The set data represents the set conditions when the screen display data is supplied to the display device 2. The storage device 11 is, for example, a non-volatile or volatile semiconductor memory such as a RAM (Random Access Memory), a ROM (Read Only Memory), a flash memory, an EPROM (Erasable Programmable ROM), an EEPROM (registered trademark) (Electrically EPROM), a magnetic disk, a floppy disk, an optical disk, a compact disk, a minidisk, a DVD (Digital Versatile Disk), etc.

[0032] Figure 2 It shows Figure 1 an example of the information stored in the set data storage unit 111 shown. In Figure 2 a plurality of set data are shown. Figure 2 The plurality of set data shown respectively include, as set items, the resolution of the display device 2, the data width of the screen display data, the scanning direction when the display device 2 displays the screen display data, and the driving method of the display device 2. These set items are used as set conditions when generating the screen display data. The resolution of set data #1 and set data #4 is GA (Video Graphics Array) (640×480), the resolution of set data #2, set data #5, and set data #7 is XGA (eXtended Graphics Array) (1024×768), and the resolution of set data #3 and set data #6 is SXGA (Super eXtended Graphics Array) (1280×1024). In addition, the data width of set data #1 to set data #3 and set data #5 to set data #7 is 8 bits, and the data width of set data #4 is 6 bits. The scanning direction of set data #1 to set data #3 and set data #5 to set data #7 is forward, and the scanning direction of set data #4 is reverse. The driving method of set data #1 is line inversion, the driving methods of set data #2 to #4 and set data #6 are dot inversion, the driving method of set data #5 is dot inversion 1×1, and the driving method of set data #7 is dot inversion 1×2.

[0033] The arithmetic unit 12 has a control unit 121 that controls the operation of the control device 1. The arithmetic unit 12 can be dedicated hardware or a CPU (Central Processing Unit). When the arithmetic unit 12 is dedicated hardware, it can be a single circuit, a composite circuit, a programmed processor, a parallel-programmed processor, an ASIC (Application Specific Integrated Circuit), an FPGA (Field Programmable Gate Array), or a combination thereof. The control unit 121 performs a setting process of selecting setting data to be used when controlling the display device 2. The control unit 121 performs the setting process by using Figure 3 , Figure 4 shown screens, that is, by selecting the setting data to be used by the operator, the setting data to be used when controlling the display device 2 is selected. Figure 3 represents Figure 1 Figure 1 showing the first example of the setting screen displayed by the control device 1 on the display device 2. Figure 4 represents Figure 1 Figure 2 showing the second example of the setting screen displayed by the control device 1 on the display device 2.

[0034] The control device 1 can supply screen display data including a test pattern to the display device 2, and the test pattern is used to determine whether the setting data corresponding to the screen display data is suitable for the display device 2 for displaying the screen display data. For example Figure 3 shown first example of the screen display data includes test patterns P such as a color display pattern, a gradient pattern, a flicker confirmation pattern, and an outermost periphery confirmation pattern, and a message screen MS1 that prompts the operator to perform a pre-specified operation when receiving screen display data suitable for the display device 2. Figure 3 The message screen MS1 shown in

[0035] contains the message "Please press the Enter button when the pattern on the inspection screen is correctly displayed.", and when the operator determines that the display is correct, a prompt is given to perform a pre-specified operation. Figure 4 In addition, Figure 4The message screen MS2 shown contains the message "When compared with A, it is normal for B to appear to flicker. Please press the Enter button." When the pattern TP-1 is displayed normally and an abnormality occurs in the display of the achromatic pattern TP-2, a prompt is given to cause the operator to perform a predetermined operation. The above-described operation is Figure 2 in cases where the resolution, data width, etc. are the same as in setting data #5 and setting data #7, but the driving method is different, Figure 4 the driving method test pattern TP shown is displayed, whereby it is possible to identify the display device 2 suitable for setting data #5 and the display device 2 suitable for setting data #7, and the selection of the setting data can be made more accurately.

[0036] The control unit 121 sequentially sends a plurality of screen display data corresponding to the plurality of setting data stored in the setting data storage unit 111 to the connected display device 2, causing Figure 3 、 4 the screen shown to be displayed on the display device 2, and by obtaining the operation information of the operator, it is possible for the operator to select the setting data to be used when supplying the screen display data to the display device 2.

[0037] The input / output interface unit 13 has a data output unit 131 that outputs data from the control device 1 and a data input unit 132 that inputs data to the control device 1, and is an input / output interface for data with respect to the control device 1. In Embodiment 1, the data output unit 131 outputs screen display data to the display device 2, and the data input unit 132 inputs operation information from the display device 2. The data output unit 131 and the data input unit 132 can each use, for example, an interface corresponding to the method of forwarding display data through a parallel RGB (Red Green Blue) signal, which uses a CMOS (Complementary Metal Oxide Semiconductor) circuit; an interface corresponding to the method of forwarding display data through a low-amplitude high-speed differential signal called LVDS (Low Voltage Differential Signaling), which uses a differential circuit; and a general-purpose unidirectional communication interface such as serial communication.

[0038] The display device 2 includes a display unit 21, an operation unit 22, and an input / output interface unit 23. The display unit 21 displays the screen display data input from the control device 1. The operation unit 22 is physical buttons, touch sensors, etc. provided on the display device 2 for operation. In the case of the display device 2 having a touch sensor, the operation unit 22 can obtain operation information using software keys. The input / output interface unit 23 includes a data output unit 231 that outputs data from the display device 2 and a data input unit 232 that inputs data to the display device 2, and is an input / output interface for data with respect to the display device 2. In Embodiment 1, the data output unit 231 outputs operation information to the control device 1, and the data input unit 232 inputs the screen display data from the control device 1. The data output unit 231 and the data input unit 232 can each use a general unidirectional communication interface such as parallel RGB, LVDS, or serial communication. In Embodiment 1, the data output unit 131 of the control device 1 and the data input unit 232 of the display device 2 are connected to form a unidirectional communication interface for transmitting data from the control device 1 to the display device 2.

[0039] Figure 5 is used to Figure 1 The flowchart for explaining the operation of the control device 1 shown in the figure. When the control unit 121 of the control device 1 starts the setting process by connecting the display device 2 and the control device 1, it sequentially reads one of the multiple setting data stored in the setting data storage unit 111 (step S101). For example, in the case where the multiple setting data shown in Figure 2 is stored in the setting data storage unit 111, the control unit 121 can sequentially read the setting data from the top.

[0040] The control unit 121 sends the screen display data based on the read setting data to the display device 2 via the data output unit 131 (step S102). The control unit 121 waits for a preset time and determines whether there is operation information indicating confirmation within this time (step S103).

[0041] In the case where operation information indicating confirmation is not input from the display device 2 (step S103: No), the control unit 121 repeats the process from step S101. If the setting data is not suitable for the display device 2, correct display cannot be performed and the operator cannot perform a confirmed operation. In this case, the control unit 121 of the control device 1 reads the unread setting data and sends the screen display data generated based on different setting data to the display device 2.

[0042] When it is determined that operation information is input from the display device 2 (step S103: Yes), the control unit 121 selects the setting data to be used based on the operation information (step S104). Specifically, the control unit 121 selects the setting data corresponding to the screen display data displayed on the display device 2 when the operation information is received, and uses it as the setting data to be used when controlling the display device 2.

[0043] Figure 6 is a flowchart for explaining the operation of the Figure 1 display device 2 shown. The display device 2 determines whether it has received screen display data from the control device 1 (step S201). When it has received the screen display data (step S201: Yes), the display unit 21 of the display device 2 displays the received screen display data (step S202). When it has not received the screen display data (step S201: No), the process of step S202 is omitted. Next, the operation unit 22 determines whether it has received an operation from the operator (step S203).

[0044] When it has received an operation (step S203: Yes), the operation unit 22 sends operation information based on the received operation to the control device 1 (step S204). When it has not received an operation (step S203: No), the display unit 21 repeats the process from step S201.

[0045] If the control device 1 performs the Figure 5 operation shown, and the display device 2 performs the Figure 6 operation shown, so that the control device 1 sequentially sends the screen display data corresponding to each of the multiple setting data to the display device 2, then the display device 2 displays the received screen display data on the display unit 21. In addition, the control device 1 waits for operation information from the display device 2 at a preset time. Among the screen display data sent by the control device 1, there are a test pattern of the display device 2 for determining whether the setting data corresponding to the screen display data is suitable for displaying the screen display data, and a message screen for prompting the operator to perform a preset operation when receiving the screen display data suitable for the display device 2. If this screen display data is displayed on the display unit 21, after the operator observes the displayed test pattern and determines that it is correctly displayed, the operator performs the operation shown on the message screen. For example, observe in Figure 3 、 4If the operator of the display screen illustrated in the example determines that the display is correct, the Enter button is pressed. If the operator performs a pre-specified operation, the display device 2 outputs operation information indicating the operation to the control device 1. When there is operation information indicating a definite operation within a pre-specified time, the control device 1 selects the setting data to be used when controlling the display device 2 based on this operation information. Additionally, when the screen display data is not data suitable for the display device 2, the operator does not perform a confirmation operation. Therefore, the control device 1 does not receive operation information indicating a definite operation within the pre-specified time, but reads new setting data and sends the screen display data based on the next setting data to the display device 2. The actions described above are repeated until a confirmation operation is performed by the operator.

[0046] As described above, the control device 1 according to Embodiment 1 includes: a setting data storage unit 111 that stores setting data indicating setting conditions for supplying screen display data to the display device 2, which includes at least one of the resolution of the display device 2, the scanning direction when the display device 2 displays the screen display data, and the driving method of the display device 2, and stores a plurality of setting data that are different according to the type of the display device 2; and a control unit 121 that sequentially sends a plurality of screen display data corresponding to the respective plurality of setting data to the connected display device 2, causes message screens MS1, MS2 for prompting the operator to perform a pre-specified operation when receiving screen display data suitable for the display device 2 to be displayed on the display device 2, and performs a setting process for selecting the setting data to be used based on the operation information for the message screens MS1, MS2. In addition, in the above-described Embodiment 1, the setting data is set to include the resolution of the display device 2, the data width of the screen display data, the scanning direction when displaying the screen display data, and the driving method of the display device 2, but the setting data does not necessarily have to include all of these setting items. It is sufficient to include at least one of the resolution, the scanning direction, and the driving method. With the control device 1 having the above-described structure, it is possible to easily perform settings for screen displays that are different for each display device 2 without making the device structure complicated. Specifically, according to the control device 1, in order for the display device 2 to enable the operator to determine whether the screen display is correct, if the operation of the operator can be received by the operation unit 22, there is no need to provide an additional function such as a circuit for determining whether the screen display is correct.

[0047] In addition, in a numerical control device having an image processing function, in a method of using a dedicated cable for each display device 2 as used in the past, a signal line for identifying the type of the display device 2 is provided in the dedicated cable, and the type of the connected display device 2 is identified by the numerical control device reading the information of the signal line for identification. In this method, a dedicated cable is required for each type of the display device 2, and an identification signal line needs to be added to a general-purpose image transmission cable. Therefore, there is a problem that the number of signals in the cable and the number of terminals of the connector for connecting the cable increase. However, according to the control device 1, the type of the connected display device 2 can be identified even without using a dedicated cable. Therefore, one type of cable can be commonly used as the cable prepared for the display device 2, and the terminals for discriminating the type of the display device 2 can be omitted.

[0048] Embodiment 2.

[0049] Figure 7 FIG. is a diagram showing the configuration of a display control system 200 according to Embodiment 2. The display control system 200 includes a control device 1-1 and a display device 2. Hereinafter, detailed description of the same parts as those in Embodiment 1 will be omitted, and mainly the parts different from those in Embodiment 1 will be described.

[0050] The control device 1-1 includes a storage device 11-1, an arithmetic device 12-1, and an input / output interface section 13. The control device 1-1 is connected to the display device 2 via a transmission line, and supplies the screen display data and ON / OFF signals for display to the display device 2 using the connected display device 2.

[0051] The storage device 11-1 includes a setting data storage section 111-1. The setting data storage section 111-1 stores a plurality of setting data different for each type of the display device 2. Figure 8 It is a diagram showing Figure 7 an example of the information stored in the setting data storage section 111-1 shown. The setting data stored in the setting data storage section 111-1 includes signal timing in addition to resolution, data width, scanning direction, and driving method as setting items. The signal timing indicates the transmission timing of the screen display data.

[0052] The arithmetic unit 12-1 has a control unit 121-1. On the basis of the functions of the control unit 121 in Embodiment 1, the control unit 121-1 controls the ON signal for starting the display unit 21 of the display device 2, the OFF signal for stopping the display unit 21, and the timing for sending the screen display data to the display device 2 based on the signal timing included in the setting data. The control unit 121-1 has the following function, that is, by sending the ON signal and the OFF signal to the display device 2, the time for the display device 2 to display the screen display data is controlled. Depending on the proficiency of the operator and the working environment, the time taken until the operator observes the display screen and determines whether the display is normal is different. By controlling the time for the display device 2 to display the screen display data, the control unit 121-1 can change the time available for the operator to operate.

[0053] Figure 9 is for explaining Figure 7 the control timing of the control device 1-1 shown in the figure. The control device 1-1 controls the timing of sending the screen display data and the ON signal generated based on the setting data, and the timing of sending the OFF signal based on the signal timing included in the setting data, so that the duration Δt 1-1 during which the screen display data based on the setting data #1 is displayed ON and the duration Δt 2-1 from when the screen display data based on the setting data #1 is displayed OFF until the screen display data based on the next setting data #2 is displayed ON can be controlled. Similarly, for the setting data #2, the duration Δt 1-2 during which the display is ON and the duration Δt 2-2 during which the display is OFF can be controlled, and for the setting data #3, the duration Δt 1-3 during which the display is ON and the duration Δt 2-3 during which the display is OFF can be controlled. Here, Figure 8 the signal timing is the duration for each setting data to be ON set through A, B, and Bα corresponding to the setting data, but the duration for being OFF can also be set.

[0054] Figure 10 is for explaining Figure 7 the operation of the control device 1-1 shown in the figure. In addition, the same reference numerals are used for the same parts as Figure 5 to omit the detailed description.

[0055] If the display device 2 is connected to the control device 1-1, the control unit 121-1 of the control device 1-1 sequentially reads the setting data (step S101). The control unit 121-1 sends the screen display data based on the read setting data and the ON signal of the display unit 21 of the display device 2 to the display device 2 (step S102-1). Steps S103 and S104 are Figure 5 the same. When there is no operation information indicating determination within a preset time (step S103: No), the control unit 121-1 sends the OFF signal of the display unit 21 of the display device 2 to the display device 2 (step S105), and returns to the process of step S101.

[0056] As described above, in the second embodiment, the setting data includes a signal timing indicating the transmission timing of the screen display data as a setting item. Setting items such as resolution, data width, scanning direction, and driving method are used as setting conditions when generating the screen display data. In contrast, the transmission timing is used as a supply condition when supplying the generated screen display data to the display device 2. The control unit 121-1 of the control device 1-1 determines the transmission timing of the screen display data for each setting data based on the signal timing. Therefore, the operator can determine whether the transmission timing of the screen display data is suitable for the display device 2. Depending on the type of the display device 2, if the restrictions on the image display data and the ON signal for controlling the start of power supply are not observed, abnormalities may sometimes occur during display. In the second embodiment, by adding the signal timing to the setting data, it is also possible to determine whether the setting data is suitable for the display device 2 as described above.

[0057] Embodiment 3.

[0058] Figure 11 FIG. is a diagram showing the configuration of a display control system 300 according to Embodiment 3. The display control system 300 includes a control device 1-2 and a display device 2. Hereinafter, detailed descriptions of the same parts as those in Embodiment 1 will be omitted, and mainly the parts different from those in Embodiment 1 will be described.

[0059] The control device 1-2 includes a storage device 11-2 and an arithmetic device 12-2. On the basis of the setting data storage unit 111, the storage device 11-2 further includes a hold data storage unit 112. The hold data storage unit 112 has a function of holding the selected setting data. The hold data storage unit 112 stores NULL in the initial state.

[0060] The arithmetic unit 12-2 has a control unit 121-2. Similar to the control unit 121, the control unit 121-2 has a function of performing setting processing, and stores the set data selected through the setting processing in the holding data storage unit 112. When starting up, if the set data is held in the holding data storage unit 112, the control unit 121-2 controls the display device 2 using the held set data, and the setting processing can be omitted. When there is no set data held in the holding data storage unit 112, the control unit 121-2 performs the setting processing.

[0061] Figure 12 is used to Figure 11 The flowchart for explaining the operation of the control device 1-2 shown. When starting up, the control unit 121-2 of the control device 1-2 reads the held data from the holding data storage unit 112 (step S106). The control unit 121-2 determines whether there is held data (step S107). When there is held data (step S107: Yes), the control unit 121-2 selects the set data stored in the holding data storage unit 112, that is, the held data, as the set data to be used for controlling the display device 2 (step S109), and controls the display device 2 using the selected set data.

[0062] When there is no held data (step S107: No), the control unit 121-2 performs the setting processing (step S100). In addition, the setting processing in step S100 corresponds to Figure 5 the processing of steps S101 to S104 shown. When the setting processing ends, set data is selected, so the control unit 121-2 stores the selected set data in the holding data storage unit 112 (step S110), and controls the display device 2 using the selected set data.

[0063] As described above, the control device 1-2 according to the third embodiment includes a holding data storage unit 112 that holds the selected setting data. Therefore, if the setting data is selected through one setting process, the selected setting data is held. As a result, there is no need to perform the setting process every time the device is started. In addition, when the holding data storage unit 112 holds the setting data, the control unit 121-2 controls the display device 2 using the held setting data, and performs the setting process when the holding data storage unit 112 does not hold the setting data. Therefore, after performing the setting process once, the setting process can be omitted, and the setting process can be performed when the display device 2 is connected for the first time. In addition, by deleting the setting data held in the holding data storage unit 112, the setting process can be performed again when it is necessary to perform the setting process, such as when connecting to a display device 2 different from the previous one. For example, as a method of deleting and resetting the setting data held in the holding data storage unit 112, consider the following method: while pressing a specific key of the control device 1-2, perform a predetermined operation such as starting, thereby forcibly writing NULL to the holding data storage unit 112.

[0064] Embodiment 4.

[0065] Figure 13 FIG. is a diagram showing the configuration of a display control system 400 according to the fourth embodiment. The display control system 400 includes a control device 1-3 and a display device 2. The control device 1-3 includes a storage device 11-2, an arithmetic device 12-3, and an input / output interface unit 13. The arithmetic device 12-3 includes a control unit 121-3. Hereinafter, the detailed description of the same parts as those in the third embodiment will be omitted, and mainly the parts different from those in the third embodiment will be described.

[0066] In the third embodiment, when there is holding data in the holding data storage unit 112, the control of the display device 2 is directly started using the holding data. However, in the fourth embodiment, when there is holding data in the holding data storage unit 112, the screen display data based on the setting data as the holding data is sent to the display device 2, and the order of making the operator confirm whether the display is correct is performed.

[0067] Figure 14 is used to Figure 13 FIG. shows a flowchart for explaining the operation of the control device 1-3 shown. Steps S106 and S107 are the same as Figure 12Same. When there is held data (Step S107: Yes), the control unit 121-3 sends the screen display data based on the held setting data to the display device 2 (Step S111). Further, the control unit 121-3 determines whether there is operation information indicating determination within a preset time (Step S112). When there is operation information indicating determination within the preset time (Step S112: Yes), the control unit 121-3 selects the setting data to be used based on the operation information (Step S113), and ends the process.

[0068] When there is no operation information indicating determination within the preset time (Step S112: No), the control unit 121-3 writes NULL to the held data storage unit 112 to reset it (Step S115). When there is no held data initially (Step S107: No) and when the held data is reset in Step S115, the control unit 121-3 performs the setting process (Step S100), and stores the selected setting data in the held data storage unit 112 (Step S110).

[0069] As described above, when starting up, if there is set data held in the held data storage unit 112, the control unit 121-3 of the control device 1-3 according to Embodiment 4 sends the screen display data corresponding to the held set data to the display device 2, and when the screen display data suitable for the display device 2, causes a screen prompting the operator to determine the set data to be displayed on the display device 2. When no determination operation by the operator is received within a preset time, the held set data is deleted and the setting process is performed. Thus, similar to Embodiment 3, for the display device 2 for which the setting process shown in Step S100 has been performed once, the setting process shown in Step S100 can be omitted in the second time and later, and thus the processing time at startup can be significantly shortened. Further, even when there is held data stored in the held data storage unit 112, the screen display data based on the held set data can be displayed on the display device 2 to enable the operator to make a determination regarding determination. Further, when the connected display device 2 is changed, if the determination operation for the held set data is not performed, the setting process shown in Step S100 can be performed again.

[0070] Embodiment 5.

[0071] Figure 151 is a diagram showing the structure of a display control system 500 according to Embodiment 5. The display control system 500 includes a control device 1-4 and a display device 2. The control device 1-4 includes a storage device 11-4 and a computing device 12-4. The storage device 11-4 includes a setting data storage unit 111-1 and a holding data storage unit 112. The computing device 12-4 includes a control unit 121-4. Hereinafter, detailed descriptions of the same parts as those of Embodiment 4 will be omitted, and the parts different from those of Embodiment 4 will be mainly described.

[0072] In addition to the functions of the control unit 121 - 3 according to the fourth embodiment, the control unit 121 - 4 has a function of transmitting an ON signal and an OFF signal to the display unit 21 of the display device 2 based on the signal timing of the setting data and controlling the transmission timing of the screen display data.

[0073] Figure 16 It is used for Figure 15 The flowchart for explaining the operation of the control device 1 - 4 is shown. Figure 16 The flowchart shown in the figure is different from the embodiment 4 in that Figure 14 The flowchart shown includes step S111 - 1 instead of step S111 , includes step S115 - 1 before step S115 , and includes the setting process of step S300 instead of the setting process of step S100 .

[0074] When the retained data exists (step S107 : Yes), the control unit 121 - 4 transmits screen display data based on the retained setting data and an ON signal of the display unit 21 of the display device 2 to the display device 2 (step S111 - 1 ).

[0075] When the display device 2 displaying the screen display data sent in step S111 - 1 does not display certain operation information within a predetermined time (step S112 : No), the control unit 121 - 4 sends an OFF signal of the display unit 21 of the display device 2 to the display device 2 (step S115 - 1 ).

[0076] In addition, when no data is retained (step S107: No) and after the processing of steps S115-1 and S115, the control unit 121-4 performs the equivalent Figure 10 The process of setting up the process of step S101 to step S105 shown in FIG.

[0077] As described above, according to the control device 1 - 4 according to the fifth embodiment, the same effects as those of the fourth embodiment can be obtained, and appropriate display settings can be performed even when the signal timing is included in the setting data.

[0078] The structure shown in the above embodiments represents an example, and it can also be combined with other known technologies, or the embodiments can be combined with each other. Without departing from the gist, a part of the structure can also be omitted or changed.

[0079] For example, in the above embodiment, the data input units 132 of the control devices 1, 1-1 to 1-4 are connected to the display device 2 and receive operation information generated by the input via the operation unit 22 provided on the display device 2. However, this embodiment is not limited to this example. It is sufficient that the data input unit 132 can receive the operation information. For example, the data input unit 132 itself can be an operation unit such as a button, or an operation unit such as a mouse or a keyboard can be connected to the data input unit 132, and the operation information can be input to the data input unit 132 via the operation unit.
