Description

  The present invention relates to a video display device and a video display device setup method, and more particularly to a video display device having different specifications depending on a destination and the like, and a setup method for producing the video display device.

  Conventionally, in the field of video display devices such as liquid crystal televisions and CRT televisions, for example, different signal processing circuits, power supply circuits, etc. are required for each destination where the video signal system, power supply specifications, etc. are different. Product planning and product development have been carried out on the assumption that products with different components are shipped for each destination.

  An example of standardization of product components regardless of destination or product specification is, for example, a personal computer based on the PC-AT standard established by IBM. Since various manufacturers around the world manufacture parts that meet this standard, there are many products that are compatible, and the price is being reduced.

  As a result of the standardization of parts due to such a standard, products are produced by a build-to-order method called BTO. In the production of personal computers by BTO, for example, a system in which a CPU, a hard disk device and the like are provided in a common housing is employed. Also, in personal computers, product variations are being developed by option boards installed in expansion slots.

  For example, in the microprocessor system disclosed in Patent Document 1, an ID indicating its own specification is provided on a circuit board mounted in each slot, and an address used when the microprocessor reads the ID is programmed in advance. Rather than being determined, it is given from the backplane according to the slot position where the circuit board is mounted. On the other hand, by assigning an ID reading space in the microprocessor address space, the microprocessor recognizes the slot position of the circuit board function, and the address for the original function of each circuit board is printed on the board. It becomes possible to continue between.

Patent Document 2 discloses an electric device that can be adjusted to a factory setting by switching to an initial setting mode by inputting a signal to an attached external input terminal without using a special device or component. . The electrical equipment has a microcomputer that can be switched to the initial setting mode and an external input terminal. Connect the external input terminal to the microcomputer and input a signal of a type other than the input signal during normal use to this external input terminal. As a result, the microcomputer is switched to the initial setting mode.

As described above, in the area related to personal computers, for example, the standardization of parts is progressing due to the above-mentioned standardization. In contrast, in video display devices such as liquid crystal televisions and CRT televisions, It was difficult to share the components.
For example, a video display device has a complicated circuit configuration, and various types of designs must be performed according to specifications. For this reason, when designing is started from the beginning for each specification, a long design period is required.

  In addition, the conventional video display device has a drawback in that it is not possible to simultaneously develop products for each destination, although the circuit blocks are not standardized, although there is a degree of design freedom. Conventionally, when products for each destination are sequentially developed, these are designed in series, and it is necessary to design each product for each product even if there is an identical circuit for each product.

  Also, in the field of video display devices such as liquid crystal televisions and CRT televisions, compared to personal computers, for example, even if they have the same screen size, the external interfaces that are widespread by destination are different, Accordingly, the required levels of price range, sound quality, and image quality differed, and as a result, various specifications had to be used, and different internal signal processing circuits had to be used. For this reason, in the video display device, it is necessary to design products for each destination and to produce them individually, and to prepare service parts for each destination / specification.

Conventionally, when setting up a video display device in a production factory or the like, for example, a special signal for entering the adjustment mode from the outside is input to the external port of the model to be produced, or input from a dedicated remote controller Since it was configured to enter the shipment initial setting mode by a signal, the setup was very troublesome.
In recent years, as the commercialization cycle has been shortened, it has become necessary to consider environmental issues, and there has been a limit to the response by the conventional design method.

FIG. 5 is a flowchart for explaining an example of a conventional production process of a video display device. Here, it is assumed that the video display device has different specifications for a plurality of destinations.
First, the production of the video display device based on the specification for the destination for which the order is received is started (step S21). If there is no change in the destination during production (step S22--no), various setups for the destination are received (step S24), final unit adjustment is performed (step S25), and the process ends. To do.

  If the destination is changed in step S22, production is performed with all conditions changed for the destination after the change (step S23). At this time, production for multiple destinations cannot be executed in parallel in one line. After production for a specific destination is performed, the line conditions are changed and the other It is necessary to produce for the destination. That is, the conventional production process has a problem that it cannot flexibly respond to a change in destination.

FIG. 6 is a diagram for explaining a unit configuration example of a conventional video display device, and schematically shows a configuration example of a television device that displays a broadcast signal selected by a tuner circuit on a display device.
The video display device transmits and receives information signals bidirectionally between the tuner circuit 31 that selects a television broadcast radio wave and outputs a demodulated video signal and audio signal, and an external device via an input / output terminal. Signal input / output circuit 32, power supply circuit 33 for supplying power to each part of the video display device, various arithmetic processing including various video signal processing and OSD processing according to the format of the input video signal, and video display A control circuit 34 that controls each part of the device, a display unit such as an LCD or a CRT, and a display unit / display control circuit 35 that performs display control of an image displayed on the display unit in accordance with a video signal output from the control circuit 34 Consists of.
Each of the above circuits is designed as a unitized circuit block, and these units are assembled on a line in the production process of the video display device to be a finished product.

  There are TV devices for destinations in Japan, the US, Europe, etc., and television devices are produced with different designs for each destination in order to satisfy different specifications for each destination. . For example, the tuner circuit 31 uses a unit having a different design for each destination in order to cope with different frequency bands depending on the destination.

  The signal input / output circuit 32 has different input / output terminal specifications depending on the destination. For example, a D terminal is used for Japan, an HDMI terminal is used for the United States, and a DVI terminal is used for Europe. Because the specifications of these terminals are different, not only the terminal shape but also the circuit specifications of, for example, an output driver and a receiver are different. Thus, in the signal input / output circuit, units having different designs are used for each destination.

Similarly, the power supply circuit 33 differs depending on the destination. For example, a power supply circuit corresponding to a 100V power supply is used in Japan, a power supply circuit corresponding to a 120V power supply is used for the United States, and for Europe. Multiple power supply circuits are used to accommodate different power supply specifications in many European countries.
Furthermore, the control circuit also varies depending on the destination. For example, the language specification for OSD (On Screen Display) display requires Japanese for Japan, English for the US, and for Europe. Multi-language specifications are needed to support different languages in many European countries.

As described above, in the conventional video display device, the circuit block unit is different for each destination, and each circuit block is designed and produced for each destination.
At this time, each circuit block has a different number of parts depending on the specifications, so the board size is not constant, and the circuit block is designed as a unit having a different size or a different I / F specification for each destination.
Therefore, a circuit block unit for a specific destination cannot be replaced with a unit for another destination, and basically a circuit design is made independently for each destination.

  In this way, even with the same model of television apparatus, a plurality of circuit designs had to be performed according to the specifications for each destination, and the design period was prolonged. Also in the production process, it is necessary to set up for each destination, which makes the production process complicated and unreasonable. In addition, even after the product sales, it is necessary to have a lot of service parts for each specification depending on the destination, and there are also problems in terms of resource saving.

  In other words, in conventional video display devices such as liquid crystal televisions and CRTs, design efficiency decreases due to prolonged design, design duplication, and time lag, etc., and the increase in parts and production due to production by destination Problems such as a decrease in productivity due to inflexibility of the process have occurred.

  The present invention has been made in view of the circumstances as described above, and can shorten the product design period and improve design efficiency, and can save resources and improve productivity by reducing parts and the like.

FIG. 1 is a block diagram for explaining an embodiment of a video display device according to the present invention, and shows a unit configuration of a liquid crystal display device as an example of the video display device.
The liquid crystal display device 10 basically has a configuration in which circuit blocks as shown in FIG. 1 are combined.

  That is, the liquid crystal display device 10 is bi-directional between a tuner circuit board unit 1 that selects a television broadcast radio wave and outputs a demodulated video signal and audio signal, and an external device via an input / output terminal. Signal input / output circuit board unit 2 for transmitting and receiving information signals, power supply circuit board unit 3 for supplying power to each part of the video display device, and various video signal processing and OSD processing according to the format of the input video signal Control circuit board unit 4 for performing various arithmetic processing including control of each part of the video display device, a display unit (liquid crystal monitor) 5 using an LCD panel, and a video signal output from the control circuit 4 for display on the display unit 5 The A / V circuit board unit 6 is provided with a display control circuit that performs video display control.

The control circuit board unit 4 includes a control circuit 4a that performs control arithmetic processing and a memory 4b that stores setup data to be described later. As the memory 4b, an E ² PROM can be applied, and a flash memory or an S-RAM may be used instead of the E ² PROM, and the configuration is not limited. The memory 4b corresponds to storage means for holding information for determining the use of a component in the present invention.
The signal input / output circuit board unit 2 can receive an operation signal transmitted from the remote controller 7.

Each of the circuit board units is designed as a circuit block unitized on the board, and these circuit board units are assembled on the line in the production process of the liquid crystal display device 10 to become a finished product.
At this time, as the circuit board unit according to the present invention, a plurality of types of board units are prepared in advance for each specification. Each circuit board unit holds ID information capable of discriminating its own specification.

  Each circuit board unit is designed in advance so as to have the same board size and the same connection specifications for the fixing mechanism and the counterpart board unit. Thus, circuit board units having the same function can be fixed at the same position on the chassis regardless of the specifications and can be connected to the counterpart circuit board unit.

By standardizing the shape and connection specifications of the circuit board unit in this way, each circuit board unit can be freely configured according to the required specifications, and combinations of circuit board units are also free. Can be done.
In addition, the design of each circuit board unit can be started at the same time according to the specifications. For example, internal circuits that overlap with multiple specifications can be shared, so that the design can be promoted rationally. Become.

  The specifications of the liquid crystal display device 10 as described above differ depending on the destination, for example, and a plurality of types of models having different specifications are configured. In addition, for example, the specifications differ depending on the method of the video signal received and displayed by the liquid crystal display device 10. Different destinations inevitably result in different video signal systems. Alternatively, the specifications differ depending on the type of OSD language used for display on the liquid crystal display device 10. In addition, for example, models with different specifications can be configured by a high-end model and a low-end model among related models.

As described above, the liquid crystal display device 10 has a plurality of types of models having different specifications, and the specifications are individually set according to the destination.
In the following description, the liquid crystal display device 10 in a case where the destinations are different will be described as an example, but there may be various settings for the conditions having different specifications.

  On the production line of the liquid crystal display device 10, a liquid crystal display device for a specific destination is assembled for each destination using a corresponding circuit board unit. Thereafter, in the setup process, the control circuit 4a of the control circuit board unit 4 incorporated in the liquid crystal display device 10 reads the ID of each circuit board unit and sets software for the destination.

  The control circuit board unit 4 basically retains software for all destinations, determines the corresponding destination according to the ID of each assembled circuit board unit, and is set so as to operate with the corresponding software. To do. Further, the control circuit board unit 4 can detect an impossible combination of circuit board units from the ID of each circuit board unit, and in this case, an error can be notified by a predetermined means.

That is, in this example, the control circuit board unit 4 that is a part of the components of the liquid crystal display device 10 is used in common in different specifications. The A / V circuit board unit 6 can be used in common regardless of specifications.
Then, the common control circuit board unit 4 and A / V circuit board unit 6 are combined with different components (tuner circuit board unit 1, power supply circuit board unit 3, signal input / output circuit board unit 2) for each specification. Thus, the liquid crystal display device 10 is configured.

FIG. 2 is a diagram for explaining an example of a combination of IDs set in each circuit board unit. Here, as a circuit board unit constituting the liquid crystal display device 10, as shown in FIG. 1, a tuner circuit board unit 1, a signal input / output circuit board unit 2, a power circuit board unit 3, a control circuit board unit 4, and an A / A The V circuit board unit 6 is provided.
Three destinations will be prepared: Japan (Japan), the US, and Europe.

  Then, an ID for determining the destination is set for each circuit board unit. Although the contents of the ID are schematically shown here, the data contents of the ID are not particularly limited in the present invention, and an ID unique to the circuit board unit can be set as appropriate. In addition, the ID set at this time does not need to include data that can identify the destination, and the control circuit board unit 4 that has acquired the ID can identify that the specific ID is set for the specific destination. I just need it. In this case, the destination corresponding to the acquired ID may be determined based on the ID identification program data stored in the memory 4b of the control circuit board unit 4 in advance.

  For example, the destination can be determined in advance so that the control circuit board unit 4 can determine the destination from the combination of the voltage values of the two signal lines. For example, if the voltage value of the two signal lines is H / L (high / low), it is set for domestic use, if it is H / H, it is for the US, if it is L / H, it is set for Europe, etc. be able to. When each circuit board unit is incorporated and automatic setup is performed, the control circuit 4a of the control circuit board unit 4 determines the destination of each circuit board unit from the voltage value of the signal line of each circuit board unit. be able to.

  Here, it is assumed that an ID is set for each circuit board unit in the form shown in FIG. In this case, since the A / V circuit board unit 6 can be used in common even if the destination is different, the same ID (* A) is set. In addition, the control circuit board unit 4 holds software that can handle all destinations, obtains the ID of each circuit board unit, and sets the software. Therefore, the same ID (* D) is used regardless of the destination. ).

  Then, the control circuit 4a of the control circuit board unit 4 collates IDs acquired from other circuit board units according to the ID combination rules shown in FIG. 2, and for a specific destination for a specific ID combination. It can be determined that the circuit board unit is connected. For example, it can be seen that a circuit board unit having specifications for domestic use is incorporated by a combination of IDs of * A, 1B, 1C, * D, and 1E.

If the combination of the IDs of the circuit board units acquired by the control circuit board unit 4 does not match any of the ID combination rules, it can be determined that the wrong circuit board unit is mounted, and the control The circuit 4a notifies that there is an error by a predetermined method.
At this time, for example, the destination may be determined based on the ID of a predetermined specific circuit board unit, for example, the tuner circuit board unit 1. In this case, the destination is determined according to the ID of the mounted tuner circuit board unit 1, and software is set in accordance with the destination. If there is a circuit board unit having an ID that cannot be combined with the tuner circuit board unit 1, it can be determined that the circuit board unit is erroneously mounted.

As described above, the control circuit 4a of the control circuit board unit 4 determines that the ID combination is used for a specific destination when the combination of IDs matches a predetermined rule, and automatically uses it for the destination. Run setup. In the setup, the destination software is selected and set from the multi-software held by the control circuit board unit. Then, the initial values of various setting values of the liquid crystal display device 10 are automatically set up.
If the combination of IDs does not match a predetermined rule, it can be determined that there is an error, and management errors and work errors during the process can be reliably covered.

  As described above, efficient production is possible by preliminarily determining combinations of IDs of the circuit board units. In addition, for example, when a functional change occurs only in a part of the circuit board unit, it is not necessary to redesign the circuit board unit one by one. It is possible to stay.

  These IDs may be provided with extension codes for future function expansion. It is also conceivable that the code of the circuit board unit ID itself can be changed / extended by the download function. In this case, if an extension terminal is provided in advance in the circuit board unit, parts management of the circuit board unit can be performed even when functions are expanded by adding some parts in the future.

  In addition, a specification corresponding to an area including a plurality of target destinations is set up by the ID of one circuit board unit among circuit board units that differ depending on the specifications, and further to other destinations by other circuit board units. A corresponding specification may be set up. For example, the setup for Europe is performed based on the ID of the power circuit board unit 3, and the setup is performed with a specific country or region in Europe as the destination based on the ID of the tuner circuit board unit 1. You may do it.

FIG. 3 is a flowchart for explaining an example of the manufacturing process of the video display apparatus according to the present invention.
In the manufacturing process of the video display device, first, various units (circuit board units) used for the video display device are produced (step S1). Here, each circuit board unit having different specifications for each destination is produced and prepared in a state where it can be assembled.
When assembling the video display device, first, order production information (information of destination) is obtained (step S2). Then, using the necessary circuit board units according to the destination, collective production (assembly of circuit board units) for the order destination is performed (step S3).

Next, the IDs of the assembled circuit board units are checked to confirm whether there are any errors (step S4). If there is an error in the ID, the corresponding circuit board unit is replaced (step S7), and the ID is checked again.
If there is no error in the IDs of the assembled circuit board units, automatic setup for the destination is performed. Here, the software corresponding to the ID is set to operate from the multi-compatible software, and initial values of various setting values are set up for each destination. Then, final unit adjustment is performed (step S16), and a product for a specific destination is completed.

FIG. 4 is a diagram for explaining a configuration example of the production line of the video display device according to the present invention, and schematically shows the production line of the liquid crystal display device described above.
The conveyor of the production line flows from left to right in FIG. 4 (in the direction of arrow Q). The production line of the liquid crystal display device realized by the present invention can be produced on the same line even if the liquid crystal display device has different specifications for each destination, for example. In addition, the product production plan for each destination can be changed freely. In this example, it is assumed that three types of destinations, domestic, European, and US, are set.

  The production line is managed by a production management host computer 16, and each circuit board unit feeder (control circuit board unit feeder 11, power circuit board unit feeder 12, tuner circuit board unit feeder 13, signal input / output circuit). The supply and incorporation of the circuit board unit by the board unit feeder 14) are managed, and the ID check and setup of the incorporated circuit board unit and the adjustment / inspection process are managed.

  On the most upstream side of the production line, a liquid crystal display chassis 22 is first placed on a pallet 21. Then, the control circuit board unit supply machine 11 installs the control circuit board unit 4 at a predetermined position inside the chassis 22 (S11). The control circuit board unit 4 is equipped with software capable of setting all Japanese specifications for Japan, multi-language use for Europe, and English specifications for the United States.

Then, a predetermined power circuit board unit 3 according to the destination is installed at a predetermined position inside the chassis 22 by the power circuit board unit supply machine 12 (S12). The power supply circuit board unit 3 has, for example, an ID of * E, 1E for domestic use, 2E for Europe, and 3E for the US.
As described above, the specific contents of the ID are not limited at all, and any information that can be read by the control circuit 4a and whose characteristics can be identified may be used.

Next, a predetermined tuner circuit board unit 1 according to the destination is installed at a predetermined position inside the chassis 22 by the tuner circuit board unit supply machine 13 (S13). The tuner circuit board unit 1 has, for example, an ID of * B, an ID of 1B for the domestic market, 2B for the European market, and 3B for the US market.
Next, a predetermined signal input / output circuit board unit 2 according to the destination is installed at a predetermined position inside the chassis 22 by the signal input / output circuit board unit supply machine 14 (S14).

  Through the steps described so far, the necessary control circuit board unit 4, power supply circuit board unit 3, tuner circuit board unit 1 and signal input / output circuit board unit 2 are installed in the chassis 22 so that the unit can be assembled. Complete. In FIG. 4, the illustration of the step of incorporating the A / V circuit board unit 6 of FIG. 1 is omitted.

Then, after assembling each circuit board unit, automatic setup based on the ID of each circuit board unit and final adjustment and inspection of the assembly are performed.
Here, when the circuit board unit is completely assembled, the ID of each circuit board unit is checked (S15). In this case, the control circuit 4a of the control circuit board unit 4 having a multi-specification is composed of other circuit board units (the tuner circuit board unit 1, the power circuit board unit 3, and the signal input / output circuit) installed in the chassis 22. ID is acquired from each of the substrate units 2 and the like. Then, using the setup data stored and held in the memory 4b, the IDs of the other connected circuit board units are checked to determine the destination based on each ID.

  At this time, if it is determined from the ID of each circuit board unit that a unit of a different destination is used, the control circuit 4a notifies an error by a predetermined means. As a notification means, for example, an error display is performed on a predetermined display screen, or an LED is provided in each circuit board unit, and the LED of the circuit board unit in error is lit red. It can be adopted as appropriate.

Then, the control circuit 4a determines the destination based on the IDs of the other connected circuit board units, and when there is no error ID, the software corresponding to the ID operates from the multi-compatible software. Set to.
Then, the adjustment / inspection machine 15 performs setup of initial values of various setting values, fine adjustment, and inspection as a product (S16), and a product for a specific destination is completed.
