The present invention relates to, for example, a monitor device for externally displaying information output from an information processing device such as a computer, and more specifically, a "source printed circuit board, a control printed circuit board, a signal conversion circuit board", and the like. The present invention relates to a monitor device capable of simultaneously acquiring effects such as "harm generation generation suppression", "use of surplus region", and "manufacturing cost increase suppression" by directly contacting without "electrical connection body".

Recently, information processing apparatuses, such as computers, which process various data quickly according to the development of the information industry, are also rapidly developing, and in accordance with the development of such information processing apparatuses, information output from the information processing apparatuses is externally displayed. Monitor devices that display as a user are also developing rapidly.

These monitor devices are largely equipped with a "CRT-equipped monitor device" applying the characteristics of a cathode ray tube (CRT) and a "liquid crystal display unit" applying the physical and optical characteristics of a liquid crystal (LC). Monitor device ". Among these, in particular, the" monitor device with a liquid crystal display unit "can easily achieve miniaturization, light weight, low power consumption, etc., compared to the" monitor with a CRT type ". For example, the area of use is increasing.

Specific examples of such conventional " liquid crystal display unit-equipped monitor device " include, for example, US Pat. No. 5502582, "Light sourse cooler for LCD monitor," US Pat. No. 5791770, "Liquid crystal monitor." Light sourse cooler for LCD monitor, US Pat. No. 5825614, "Compact personal computer with LCD monitor", and the like.

In general, since the monitor device is often connected to various information processing devices in accordance with the situation, it is necessary to provide various signal formats according to the type of information processing device connected to the monitor device. The device, for example, a "monitor device equipped with a liquid crystal display unit" forms a structure in which a source printed circuit board and a control printed circuit board are separated from each other and mounted. In this case, the source printed circuit board and the control printed circuit board separated from each other are electrically connected by, for example, a flexible printed circuit board (FPC), thereby securing a signal transmission path therebetween.

On the other hand, a signal output from the information processing apparatus is usually an analog signal, whereas a monitor device that receives an analog signal output from the information processing apparatus, for example, a monitor apparatus with a liquid crystal display unit, has an analog signal and a data format. Since it is common to drive by this totally different signal, for example, a digital signal, a monitor device usually uses an " analog-digital convert circuit board " for converting an analog signal output from the information processing device into a digital signal. circuit board ". In this case, the analog-digital conversion circuit board is electrically connected to the control printed circuit board by, for example, a connecting cable, thereby securing a signal transmission path with the control printed circuit board. Of course, the control printed circuit board has a structure electrically connected to the source printed circuit board by the flexible circuit board as described above.

In recent years, as the debate on harmful waves emitted from electronic devices has rapidly increased, various efforts have been made to reduce them, and a large and small amount of harmful waves have emerged as an important factor for determining the quality of electronic devices.

However, a conventional monitor device, for example, a monitor device with a liquid crystal display unit, has a structure in which a source printed circuit board and a control printed circuit board are connected through a flexible printed circuit board as described above. In addition, a structure in which an analog-to-digital conversion circuit board and a control printed circuit board are connected through a connecting cable is used. In this case, a flexible printed circuit board and a connecting cable, which electrically connect the boards, are various. As the electric signal moves rapidly, a large amount of harmful waves, for example, electromagnetic waves, are generated, and these electromagnetic waves act as a defect factor that greatly degrades the quality of the finally completed monitor device.

Furthermore, since such flexible printed circuit boards, connecting cables, etc. are expensive, when the flexible printed circuit board, connecting gables, etc. are mounted inside the monitor device, not only the problem of "electromagnetic wave generation" mentioned above, but also the final finished product Another problem arises, in which the cost rises significantly.

It is best to completely remove the "flexible printed circuit board, connecting cable," etc. from the structure of the overall monitor device in order to prevent such problems as "electromagnetic wave generation" and "unnecessary increase in product cost", but in this case, Since the electrical connection relationship between each board cannot be secured smoothly, the conventional production line recognizes this deeply, but does not provide any countermeasures.

Accordingly, it is an object of the present invention to standardize the design framework of a monitor device with "flexible printed circuit boards, connecting cables" and the like removed.                         

Another object of the present invention is to smoothly secure the electrical connection between the substrates while removing the "flexible printed circuit board, connecting cable" and the like in the structure of the monitor device.

It is still another object of the present invention to minimize the generation of electromagnetic waves through the elimination of "flexible printed circuit boards, connecting cables" and the like, thereby greatly improving the quality of the finally completed monitor device.

Another object of the present invention is to remove the "flexible printed circuit board, connecting cable" and the like, so that the "electrical connectors" can be used elastically the remaining area removed.

Still another object of the present invention is to minimize the cost of the finished monitor device by removing the "flexible printed circuit board, connecting cable" and the like from the structure of the monitor device.

Still other objects of the present invention will become more apparent from the following detailed description and the accompanying drawings.

In order to achieve the above object, in the present invention, first, the control printed circuit board is changed to, for example, a flexible printed circuit board type, and then the flexible printed circuit board type control printed circuit board is directly coupled to the source printed circuit board. In this case, a coupling terminal, for example, an anisotropic conductive film or solder, is directly disposed between the flexible printed circuit board type control printed circuit board and the source printed circuit board.

In this case, since the control printed circuit board has a removable structure with the source printed circuit board, the control printed circuit board can be freely replaced in the production line according to the requirements of the information processing apparatus connected to the monitor device. Various signal formats can be provided depending on the type of information processing device connected to the device.

When this invention is achieved, since the control printed circuit board is directly connected to the source printed circuit board, in the production line, without providing a separate "electrical connection" between the control printed circuit board and the source printed circuit board, The conduction path between the control printed circuit board and the source printed circuit board can be secured smoothly. As a result, the production line can eliminate the generation of electromagnetic waves output from a separate "electrical connector."

In addition, in the present invention, a signal conversion circuit board, such as an analog-to-digital converter, is directly coupled to the above-described flexible printed circuit board type control printed circuit board.

At this time, for example, the upper surface socket for coupling the signal conversion circuit board in the energized state is further mounted on the coupling surface of the control printed circuit board, the coupling surface of the signal conversion circuit board corresponding to the upper socket is coupled to the upper socket signal A lower socket is further mounted to couple the conversion circuit board to the control printed circuit board in an energized state.

As another example, the coupling surface of the signal conversion circuit board consists of a clamp-shaped upper and lower plates, and inserts the coupling surface of the control printed circuit board between the upper and lower plates, and presses the signal conversion circuit board to the control printed circuit board. The biting connector to engage may also be mounted.

In this case, the signal conversion circuit board receives a signal output from the information processing apparatus, for example, an analog signal, transforms the analog signal into another signal suitable for driving the liquid crystal, for example, a digital signal, and controls the changed digital signal. Input to the printed circuit board.

When this invention is achieved, since the signal conversion circuit board is directly coupled with the control printed circuit board, in the production line, without providing a separate "electrical connection" between the signal conversion circuit board and the control printed circuit board, The conduction path between the signal conversion circuit board and the control printed circuit board can be secured smoothly. As a result, the production line can eliminate the generation of electromagnetic waves output from a separate "electrical connector".

In short, on the basis of the idea of the present invention described above, when standardizing the monitor device from which the "electrical connector" such as "flexible printed circuit board and connecting cable" has been removed to the standard design frame of mass production, the generation of electromagnetic waves is prevented in the production line. Not only can it be minimized, but also the remaining area from which the "electrical connector" has been removed can be used flexibly, thereby greatly improving the quality of the finished monitor device.

Hereinafter, a monitor device according to the present invention will be described in more detail with reference to the accompanying drawings.

As shown in FIG. 1, the monitor device 400 according to the present invention is electrically connected to an information processing device (not shown), for example, a main body of a desktop computer, through an connecting line 301, and an input device. For example, it forms a structure electrically connected with the keyboard 300. Of course, this keyboard 300 also has an electrical connection with the information processing apparatus.

At this time, the cover case 200 of the monitor device 400 is coupled to the rear bezel 202 having a rectangular ring-shaped storage space and the rear bezel 202 facing each other, the screen A on the front It consists of a combination of front bezels 201 defined. The cover case 200 forms a structure supported by the backing plate 203.

In general, an information processing assembly capable of quickly processing a signal input from the outside is generally built into the main body of the information processing device electrically connected to the monitor device 400. In this case, the user operates the keyboard 300 When certain information is input into the main body, the information processing assembly quickly calculates the input information and then outputs the processed information to the monitor device 400 disposed outside the main body.

In this case, as shown in FIG. 2, between the rear bezel 202 and the front bezel 201 of the cover case 200, the liquid crystal display unit 100 which directly displays the information processing result of the above-described information processing assembly to the outside. For example, the liquid crystal panel 10 is stored in a state in which its liquid crystal panel 10 is exposed to the outside of the screen A of the front bezel 201.

Here, as shown in the figure, the liquid crystal display unit 100 is composed of a combination of a mold frame 50 and a liquid crystal panel assembly disposed in front of the mold frame 50.

At this time, the mold frame 50 is formed in a rectangular ring shape to define, for example, an accommodating area in which the reflective plate, the light guide plate (not shown), and sheets (not shown) are stacked. A pair of lamps (not shown) having a light irradiation function is accommodated in the longitudinal left and right edges of the mold frame 50, and a light guide plate is disposed between the lamps, and sheets are disposed in front of the light guide plate. . Of course, the arrangement of such lamps, reflectors, light guide plate may be variously modified according to the situation of the production line.

On the other hand, the liquid crystal panel assembly is largely arranged on one axis of the lower panel 11, for example, the long axis, and the liquid crystal panel 10 including the upper panel 12 and the lower panel 11 stacked in the state of the liquid crystal. And a source printed circuit board 30 in electrical contact with a connection pad for data lines (not shown), and another one axis of the lower panel 11, for example, a short axis, and a connection pad for gate lines (not shown). It consists of a combination of gate tape carrier packages 20 in electrical contact.

In this case, for example, the common electrode and the color pixels are arranged in the upper panel 12, and the lower panel 11 opposite to the thin film transistors formed by, for example, a semiconductor thin film process, and electrically contacted with the thin film transistors. In the state, the pixel electrodes forming the electric field by the on / off operation of the thin film transistors, and the gate lines and the data lines that transmit signals to the thin film transistors while being in electrical contact with the thin film transistors described above. Is placed. The gate lines and the data lines have an electrical connection with the connection pad for the gate line and the connection pad for the data line described above.

In this case, the gate tape carrier packages 20 described above electrically contact their output terminals with the gate lines of the lower panel 11 with the gate drive IC (not shown) mounted thereon. In this case, an anisotropic conductive film for coupling them is interposed between the output terminal of the gate tape carrier packages 20 and the connection pad for the gate line of the lower panel 11.

Meanwhile, the source printed circuit board 30 described above is electrically connected to the data lines of the lower panel 11 through the source tape carrier packages 31 mounted with the source drive IC (not shown). Of course, one end of the signal pattern formed on the source printed circuit board 30 is in electrical contact with the input terminals of the source tape carrier packages 31.

In this case, an anisotropic conductive film for coupling them is interposed between the output terminal of the source tape carrier packages 31 and the connection pad for the data line of the lower panel 11.

In this case, when the assembly of the liquid crystal display unit 100 is completed, the source printed circuit board 30 described above is rotated, for example, by 180 ° in the direction of an arrow, by using bending of the source tape carrier packages 31. As a result, it forms a structure that is stably mounted on the back of the mold frame 50.

Here, the signal transmission lines (not shown) are further disposed on the lower panel 11, and the signal transmission lines are electrically connected to the source tape carrier packages 31 and the gate tape carrier packages 20 described above. The contact causes the source tape carrier packages 31 and the gate tape carrier packages 20 to have an electrical connection with each other.

On the other hand, as shown in Figure 3, when the source printed circuit board 30 is rotated and mounted on the back of the mold frame 50, the control printed circuit board 40 in a predetermined portion of the source printed circuit board 30 ) Is mounted. In this case, the back of the mold frame 50 is further provided with a metal back cover 60 to ensure the mounting stability of the control printed circuit board 40.

At this time, since the chips disposed on the control printed circuit board 40 of the present invention have not only a function of transferring a gate driving signal but also a function of transferring a source driving signal, the control printed circuit board 40 and When the source printed circuit board 30 has an electrical connection, the gate line and the data lines formed on the lower panel 11 may simultaneously receive a gate driving signal and a data driving signal for driving the thin film transistor.

As such, the "technology that allows one semiconductor chip to hold various functions at once" is commonly referred to as "one-chip technology", and when such "one-chip technology" is applied to a liquid crystal panel assembly, the production line is It is possible to induce the control printed circuit board 40 to act integrally to the role of the gate printed circuit board of the, thereby removing the gate printed circuit board from the overall structure of the liquid crystal panel assembly In the end, the production line can achieve the effect of reducing the overall thickness and weight of the liquid crystal panel assembly.

Examples of such "one chipping techniques" are presented in more detail in "Application No. 99-13650" filed by the applicant.

On the other hand, as shown in the figure, the control printed circuit board 40 is directly coupled to the source printed circuit board 30 without a separate "electrical connector". In this case, the control printed circuit board 40 is, for example, a flexible printed circuit board type.

Such a coupling method of the control printed circuit board 40 forms a gist of the present invention, and, of course, the conventional control printed circuit board does not take this coupling method at all.

Conventionally, the control printed circuit board has a structure that is coupled to the source printed circuit board through a separate "electrical connector", for example, a flexible printed circuit board, in which case the flexible printed circuit board generates a large amount of electromagnetic waves. By acting as a defective factor to generate | occur | produce, eventually, the quality of the finally completed monitor apparatus was greatly reduced.

However, in the present invention, since the control printed circuit board 40 is directly connected to the source printed circuit board 30, a separate line between the control printed circuit board 40 and the source printed circuit board 30 in the production line. Without providing an "electrical connector", a conductive path between the control printed circuit board 40 and the source printed circuit board 30 can be secured smoothly, and eventually, a separate "electrical connector" in the production line. By eliminating the generation of electromagnetic waves output from the device, it is possible to obtain an effect of greatly improving the quality of the finally completed monitor device.

Furthermore, when the present invention is achieved, the production line can eliminate the "electrical connection" such as "flexible printed circuit board" from the structure of the overall monitor device, thereby minimizing the cost of the final completed monitor device. Can be obtained additional effects.

In this case, the control printed circuit board 40 forms a detachable structure with the source printed circuit board 30. In this case, in the production line, the control printed circuit board 40 is controlled according to the requirements of the information processing device connected to the monitor device 400. Since the circuit board 40 can be freely replaced, various signal formats can be provided according to the type of the information processing device connected to the monitor device 400.

Here, as shown in Figure 4, between the control printed circuit board 40 and the source printed circuit board 30 for directly coupling the control printed circuit board 40 and the source printed circuit board 30 in an energized state. Coupling terminal 42 is further disposed. The coupling terminal 42 is made of a material, for example, an anisotropic conductive film, solder, etc., which can provide a certain level of coupling force while maintaining excellent conduction power.

At this time, as shown in the figure, the control printed circuit board 40 is further formed with signal patterns 42 for outputting an electrical signal to the source printed circuit board 30, correspondingly, the source printed circuit The substrate 30 is further provided with signal patterns 32 for receiving an electrical signal output from the control printed circuit board 40. Of course, each of these signal patterns 32 and 42 is combined through the above-described coupling terminal.

If, on the production line, based on the above-described idea of the present invention, when the monitor device from which the "electrical connector" such as "flexible printed circuit board, connecting cable" has been removed is standardized to the standard design frame of mass production, In addition to minimizing the generation of electromagnetic waves, it is possible to flexibly utilize the remaining area from which the "electrical connector" has been removed, thereby significantly improving the quality of the finally completed monitor device.

Meanwhile, as shown in FIG. 3, the signal conversion circuit board 70, for example, an analog-to-digital converter, is disposed at the end of the control printed circuit board 40. In this case, screws are disposed at four corners of the signal conversion circuit board 70, and these screws are strongly tightened at the edges of the signal conversion circuit board 70, such that the signal conversion circuit board 70 is attached to the reinforcing bracket 60. It plays the role of making it firmly fixed.

As such, the fixed signal conversion circuit board 70 receives a signal output from the information processing device, for example, an analog signal, in an electrically connected state with the above-described information processing device, and then converts the analog signal into a device suitable for driving the liquid crystal. It converts other signals, such as digital signals, and inputs the changed digital signals to the control printed circuit board 40.

In this case, the signal conversion circuit board 70 is directly coupled to the control printed circuit board 40 without a separate "electrical connection body" as in the above-described "connection relationship between the control printed circuit board / source printed circuit board".

The coupling method of the signal conversion circuit board 70 together with the control method of the control printed circuit board 40 described above is part of the gist of the present invention, and, of course, the conventional signal conversion circuit board has no such coupling method. I was not drunk.

In the conventional case, the signal conversion circuit board has a structure that is coupled to the control printed circuit board through a separate "electrical connector", for example, a connecting cable. In this case, the connecting cable is a bad factor that generates a large amount of electromagnetic waves. In the end, it acted as a detrimental effect that greatly lowered the quality of the finally completed monitor device.

However, in the present invention, since the signal conversion circuit board 70 is directly coupled with the control printed circuit board 40 as described above, in the production line, the signal conversion circuit board 70 and the control printed circuit board ( Without providing a separate "electrical connection" between the 40, it is possible to smoothly secure the conduction path between the signal conversion circuit board 70 and the control printed circuit board 40, after all, in the production line By eliminating the generation of electromagnetic waves output from the " electrical connector ", it is possible to obtain an effect of greatly improving the quality of the finally completed monitor device.

Furthermore, when the present invention is achieved, the production line can eliminate the "electrical connection" such as "connecting cable" in the structure of the overall monitor device, thereby minimizing the cost of the finished monitor device. Can be obtained.

In this case, as shown in FIG. 5, the upper socket 41 is further mounted on the coupling surface of the above-described control printed circuit board 40, and the signal conversion circuit board 70 corresponding to the upper socket 41 is provided. The lower socket 71 is further mounted on the engaging surface. In this case, a plurality of contact pins 41a are arranged in the upper socket 41, and a plurality of contact holes 71a are arranged in the corresponding lower socket 71. Of course, when the contact pins 41a are inserted into the contact holes 71a, the upper and lower sockets 41 and 71 can form a smooth energizing relationship with each other.

As described above, when the control printed circuit board 40 and the signal conversion circuit board 70 are mounted with the upper and lower sockets 41 and 71 respectively, the contact pins of the upper socket 41 ( 41a) is deeply inserted into the contact holes 71a of the lower socket 71, thereby inducing the control printed circuit board 40 and the signal conversion circuit board 70 to achieve a smooth conduction relationship. In this case, the signal conversion circuit board 70 can secure a smooth conduction path through the upper and lower sockets 41 and 71. As a result, after converting the analog signal output from the information processing apparatus into a digital signal, The changed digital signal can be quickly input to the control printed circuit board 40.

On the other hand, as shown in Figure 6, in another embodiment of the present invention, the biting connector 74 is further mounted on the mating surface of the signal conversion circuit board 70.

The biting connector 74 includes upper and lower plates 76 and 75 having a tong shape. In this case, the lower plate 75 of the biting connector 74 may include circuit patterns of the signal conversion circuit board 70. Circuit patterns 77 having a predetermined shape in electrical contact with each other are formed, and circuit patterns 77 (not shown) of a predetermined shape are further formed on the mating surface of the control circuit board 40 corresponding to the circuit patterns 77. do.

At this time, the biting connector 74 inserts the coupling surface of the control printed circuit board 40 between the upper and lower plates 76 and 75 of the biting connector 74 and presses the circuit patterns 77 formed on the lower plate 75. By causing the circuit patterns formed on the mating surface of the control circuit board 400 to be in electrical contact with each other, the control printed circuit board 40 and the signal conversion circuit board 70 are eventually induced to achieve a smooth energizing relationship. The signal conversion circuit board 70 can secure a smooth energization path through the biting connector 74. As a result, the analog signal output from the information processing apparatus is converted into a digital signal, and then the changed digital signal is converted into a digital signal. It can be quickly entered into the control printed circuit board.

On the other hand, in the monitor device 400 of the present invention having such a configuration, when a user operates the keyboard 300 to input certain information into the main body, the information processing assembly quickly calculates the input information and then processes it. The processed information is quickly output to the monitor device 400 through the connection line 301.

At this time, the signal conversion circuit board 70 mounted on the liquid crystal display unit 100 of the monitor device 400 receives a signal output from the information processing assembly, for example, an analog signal, and then converts the analog signal into driving of the liquid crystal. Other suitable signals, such as digital signals, are transformed and the modified digital signals are input to the control printed circuit board 40.

Here, as described above, since the signal conversion circuit board 70 and the control printed circuit board 40 are directly connected without a separate "electrical connector", it is possible to obtain the effect that electromagnetic waves are not generated in the production line. have.

Subsequently, the control printed circuit board 40 inputs a signal output from the signal conversion circuit board 70 to the source printed circuit board 30 electrically connected to the control printed circuit board 40.

In this case, as described above, since the control printed circuit board 40 and the source printed circuit board 30 are directly connected without a separate "electrical connector", an effect that electromagnetic waves are not generated in a production line may be obtained. Can be.

At this time, as described above, since the chips disposed on the control printed circuit board 40 not only have a function of transmitting a gate driving signal but also a function of delivering a source driving signal, the control printed circuit board 40 ) And the source printed circuit board 30 form an electrical connection, the gate line and the data lines formed on the lower panel 11 may receive a gate driving signal and a data driving signal for driving the thin film transistor at the same time. .

The signal output from the control printed circuit board 40 is then input to the source tape carrier package 31 via the source printed circuit board 30.

At this time, among the signals input to the source tape carrier package 31, the signals for driving data are connected to the lower panel via the output terminal of the source tape carrier packages 31 and the connection pad for the data line of the lower panel 11. Are input to the data lines.

Further, among the signals input to the source tape carrier package 31, the gate driving signals are passed through the output terminal of the source tape carrier packages 31 and the signal transmission lines arranged on the lower panel 11. After input to the packages 20, the output lines of the gate tape carrier packages 20 and the connection pads for the gate lines of the lower panel 11 are input to the gate lines of the lower panel 11.

Subsequently, the thin film transistors formed on the lower panel 11 are turned on and off by signals input through the gate lines and the data lines, and then the liquid crystal interposed between the lower panel 11 and the upper panel 12. By inducing rapid driving, the signal input from the information processing apparatus can be finally displayed on the screen A of the front bezel 201.

In the production line, based on the above-described idea of the present invention, when a monitor device in which the "electrical connector" such as "flexible printed circuit board and connecting cable" has been removed is standardized to a standard design frame for mass production, In addition to minimizing the occurrence, it is also possible to flexibly utilize the remaining area from which the "electrical connectors" have been removed.
