Description

  The present invention relates to a plasma display device which is an image display device using a plasma display panel.

  A plasma display panel (hereinafter abbreviated as “panel”) is a display device with excellent visibility characterized by a large screen, a thin shape, and a light weight. Many plasma display devices using this panel have been proposed.

  A panel used in such a conventional plasma display device includes a front glass substrate on which a scan electrode, a sustain electrode, a dielectric layer, and a protective layer are formed, a data electrode, an insulator layer, a barrier rib, and a phosphor layer. The formed rear glass substrate is disposed oppositely, and the periphery is sealed, and a discharge gas is sealed between them to form a discharge space.

  A drive signal for displaying an image by causing discharge in the discharge space by driving each electrode is input to the scan electrode, the sustain electrode, and the data electrode.

  These drive signals are generated in the control board, and a flexible wiring board that can be bent freely is used to connect the control board and the panel.

  Via this flexible wiring board, a drive signal generated by the control board can be sent to the electrodes of the panel to drive each electrode and cause discharge in the discharge space to display an image.

  The flexible wiring board is a so-called flexible wiring board in which a fine wiring pattern of a conductor such as copper is formed on one side or both sides of an insulating film such as polyester, that is, a wiring board that can be bent or twisted.

  The use of such a flexible wiring board is convenient because it can be bent freely to connect the boards arranged in parallel to each other and to connect many signals in a small area. This is because there are many advantages such as that the wiring pattern can be arranged and that the connector and the anisotropic conductive sheet can be used for easy connection.

  An example of connecting a control board and a panel using a flexible wiring board is described in Patent Document 1 below.

  FIG. 7 is a schematic view showing a state in which a connector 702 is mounted on a control board 701 and connected to a flexible wiring board 703 via the connector 702 in a conventional plasma display device. FIG. 7A shows a state seen from the front, and FIG. 7B shows a state seen from the side. In FIG. 7, the details are omitted and only the part directly related to the essence of the present invention is taken out and shown in order to avoid complicated and difficult to understand. Therefore, the front view and the side view are not necessarily accurate. Does not match.

  The connector 702 has a large number of connection pins 705 inside. Although the same number of connection pins 705 as the number of wirings of the flexible wiring board 703 exist, only one overlapping pin 705 is shown in the side view of FIG. Further, in the front view of FIG. 7A, only four of each of the both end sides are shown, but there are actually as many as the number of wires of the flexible wiring board 703 as described above. Further, the interval (pitch) at which the connection pins 705 are arranged is also approximate and not accurate. Furthermore, the connection pins 705 are not necessarily arranged in parallel as described above, but may be arranged in a so-called staggered pattern (shifted back and forth alternately).

  The lower portion of the connection pin 705 passes through a through hole 706 provided in the control board 701 and is connected to the control board 701. Note that the through hole 706 is shown only in the side view of FIG. 7B in order to simplify and understand the illustration, but it actually exists in the front view of FIG. 7A. In addition, priority is given to making the diameter of the through hole easy to see, and it is not accurate.

  The end of the flexible wiring board 703 is inserted from the fitting port 704 of the connector 702, and the lower surface of the flexible wiring board 703 is in contact with the contact portion 707 at the tip of the connection pin 705. This is an example in which the wiring pattern exists only on the lower surface of the flexible wiring board 703. In the example in which the wiring pattern exists on both surfaces of the flexible wiring board 703, the contact portion 707 at the tip of the connection pin 705 is the flexible wiring board. It may be in contact with the upper surface of the substrate 703.

  There are also members / mechanisms for press-contacting the flexible wiring board 703 and the connection pins 705, and locking members / mechanisms for fixing the flexible wiring board 703 and the connector 702 so as not to drop off. These are also omitted to avoid being complicated and difficult to understand.

The other end (opposite side) of the flexible wiring board 703 is in pressure contact with each electrode on the panel via an anisotropic conductive sheet, but these are not directly related to the essence of the present invention. The illustration and description are omitted.
JP 2004-258473 A

  However, in the conventional plasma display device as described above, there is a gap 708 between the connector 702 and the control board 701 due to convenience for mounting, heat countermeasures during soldering, and other reasons. The flexible wiring board 703 may be inserted by mistake.

  FIG. 8 shows a state where the flexible wiring board 793 is erroneously inserted into the gap 708. In this state, naturally, the wiring pattern on the flexible wiring board 793 and the connection pin 705 of the connector 702 are not connected, so the drive signal generated by the control board 701 is not sent to the panel, and the scan electrode, the sustain electrode, Since each electrode of the data electrode is not driven, naturally, the panel does not emit light, and immediately notices and the flexible wiring board 793 inserted by mistake is pulled out and inserted into the correct position, that is, the fitting port 704. can do.

  However, once the flexible wiring board 793 is mistakenly inserted into the gap 708, the flexible wiring board 793, the control board 701, or the connector 702 may be damaged or damaged.

  Further, during the operation test of the panel and the plasma display device, the flexible wiring board 703 was normally inserted into the fitting port 704 of the connector 702 and was operating normally. Immediately before shipment, the flexible wiring board 703 is once pulled out of the connector 702, and when the flexible wiring board 703 is connected to the connector 702 again, it may be inserted into the gap 708 by mistake without notice. There was no possibility of being shipped.

  The present invention has been made to solve the above-described problems, and for this purpose, the following configuration is employed.

  The invention according to claim 1 includes a flexible wiring board that connects the plasma display panel and the control board, and a connector that is disposed on the control board and is connected to the flexible wiring board. The plasma display device is provided with an obstacle for preventing a flexible substrate from being inserted therebetween.

  By adopting such a configuration, it is possible to prevent the flexible wiring board from being erroneously inserted into the gap between the connector and the control board.

  In the second aspect of the present invention, the obstacle is constituted by a convex portion provided on the connector.

  By adopting such a configuration, it is possible to make an error in the gap between the connector and the control board by simply changing the shape of the connector, especially its case (housing), without requiring any other changes or modifications. Therefore, it is possible to prevent the flexible wiring board from being inserted.

  According to a third aspect of the present invention, the obstacle is constituted by a component mounted on the control board.

  By adopting such a configuration, there is no need to make changes to the connector, no need to add new parts or configurations, just changing the mounting location of the parts currently in use, the connector and control board It is possible to prevent the flexible wiring board from being erroneously inserted into the gap.

  According to the present invention, it is possible to prevent the flexible wiring board from being erroneously inserted into the gap between the connector and the control board with a simple configuration with a simple and small change. An apparatus can be provided.

Part (not shown).

  This plasma display device has many other parts, but those that are not directly related to the essence of the present invention will be omitted from the illustration and description in order to avoid the complexity and clarification of the essence.

  The image signal processing unit 117 converts the image signal sig into image data indicating light emission / non-light emission for each subfield of each discharge cell.

  The data electrode driver 112 converts the image data for each subfield into a signal corresponding to each data electrode 132 (D1 to Dm), and drives each data electrode 132.

  Scan electrode driver 113 supplies a predetermined drive voltage waveform to each scan electrode 122 (SCN1 to SCNn). The sustain electrode driver 114 supplies a predetermined drive voltage waveform to each sustain electrode 123 (SUS1 to SUSn).

  The timing generator 115 generates various timing signals necessary for each electrode driver to control the drive voltage waveform based on the horizontal synchronizing signal H and the vertical synchronizing signal V, and supplies the timing signals to each electrode driver. .

  As described in the background art, the scan electrode driver 113, the data electrode driver 112, and the sustain electrode driver 114 are mounted on one or a plurality of control boards, and these drive signals are generated in the control board. . Then, the control board and the panel 100 are connected, a drive signal generated by the control board is sent to each electrode of the panel 100, the electrode is driven, a discharge is caused in each discharge cell 136 of the panel 100, and finally In order to display an image on the panel 100, a flexible wiring board that can be bent freely is used.

  As described above, the flexible wiring board is a so-called flexible wiring board in which a fine wiring pattern of a conductor such as copper is formed on one side or both sides of an insulating film such as polyester, that is, a wiring board that can be bent or twisted. . The use of such a flexible wiring board is convenient because it can be bent freely to connect the boards arranged in parallel to each other and to connect many signals in a small area. This is because there are many advantages such as that the wiring pattern can be arranged and that the connector and the anisotropic conductive sheet can be used for easy connection.

  FIG. 4 is a schematic view showing a state in which the connector 402 is mounted on the control board 401 and connected to the flexible wiring board 403 via the connector 402 in the plasma display device of the present invention. 4A shows a state viewed from the front, and FIG. 4B shows a state viewed from the side. In FIG. 4, the details are omitted and only the part directly related to the essence of the present invention is taken out and shown in order to avoid complicated and difficult to understand. Therefore, the front view and the side view are not necessarily accurate. Does not match.

  The connector 402 has a large number of connection pins 405 inside. There are as many connection pins 405 as the number of wirings of the flexible wiring board 403, but only one overlapping pin 405 is shown in the side view of FIG. Further, in the front view of FIG. 4 (A), only four of each of the both end sides are shown, but there are actually as many as the number of wires of the flexible wiring board 403 as described above. Further, the interval (pitch) at which the connection pins 405 are arranged is also approximate and not accurate. Furthermore, the connection pins 405 are not necessarily arranged in parallel in this way, but may be arranged in a so-called staggered pattern (shifted back and forth alternately).

  A lower portion of the connection pin 405 is connected to the control board 401 through a through hole 406 provided in the control board 401. Note that the through-hole 406 is shown only in the side view of FIG. 4B in order to make the illustration simple and easy to understand, but actually also exists in the front view of FIG. Priority is given to making the diameter of the through hole easy to see, and it is not accurate.

  The end portion of the flexible wiring board 403 is inserted from the fitting port 404 of the connector 402, and the lower surface of the flexible wiring board 403 is in contact with the contact portion 407 at the tip of the connection pin 405. This is an example in which the wiring pattern exists only on the lower surface of the flexible wiring board 403. In the example in which the wiring pattern exists on both surfaces of the flexible wiring board 403, the contact portion 407 at the tip of the connection pin 405 has a flexible wiring. It may be in contact with the upper surface of the substrate 403.

  There are members / mechanisms for pressing the flexible wiring board 403 and the connection pins 405, and lock members / mechanisms for fixing the flexible wiring board 403 and the connector 402 so that they do not fall off. Is also omitted to avoid being complicated and difficult to understand.

  The other end (opposite side) of the flexible wiring board 403 is in pressure contact with each electrode on the panel via an anisotropic conductive sheet, but these are not directly related to the essence of the present invention. The illustration and description are omitted.

  In the plasma display device of the present invention, there is a gap 408 between the connector 402 and the control board 401 due to the convenience when the connector 402 is attached to the control board 401, heat countermeasures during soldering, and other reasons. A convex portion 440 exists in the connector 402 so as to fill a part of the connector 402. In FIG. 4, only one convex portion 440 is shown, but the number of convex portions 440 is not limited to one, and a plurality of convex portions 440 may exist.

  Since this convex portion 440 exists so as to fill a part of the gap 408, the flexible wiring board 403 is not erroneously inserted into the gap 408.

  Therefore, the convex portion 440 may have any size, number, and shape that can prevent the flexible wiring board 403 from being erroneously inserted into the gap 408, and the tip of the convex portion 440 is not necessarily the control board. It is not necessary to be in contact with 401, and there may be a gap. However, the gap should not be large enough to insert the flexible wiring board 403.

  Further, the convex portion 440 is not necessarily required to be the same size as the connector 402 in the depth direction of the connector 402, and the convex portion 440 may be only part of the depth direction of the connector 402. . However, the size or position can prevent the flexible wiring board 403 from being erroneously inserted into the gap 408, or can immediately determine that the flexible wiring board 403 has been erroneously inserted into the gap 408. Must be a thing.

  As described above, in the plasma display device of the present invention, the flexible wiring board 403 is mistakenly provided only by providing the convex portion 440 on the connector 402 for connecting the flexible wiring board 403, and no other changes are required. The insertion into the gap 408 can be prevented, and the flexible wiring board 443, the control board 401, or the connector 402 can be prevented from being damaged or damaged.

  Furthermore, in the worst case, it is possible to prevent the flexible wiring board 403 from being shipped in a state where the flexible wiring board 403 is inserted into the gap 408 by mistake.

(Embodiment 2)
Next, the plasma display apparatus in Embodiment 2 of this invention is demonstrated using drawing.

  The plasma display device according to the second embodiment of the present invention is the same as the plasma display device according to the first embodiment of the present invention in many respects. Therefore, the plasma display device according to the second embodiment of the present invention is the same as the plasma display device according to the present invention. The description of the same points as the plasma display device of the first embodiment will be omitted, and only the differences between the plasma display device of the second embodiment of the present invention and the plasma display device of the first embodiment of the present invention will be described. To do.

  FIG. 5 shows a schematic diagram of a state in which the connector 502 is mounted on the control board 501 and connected to the flexible wiring board 503 via the connector 502 in the plasma display device of the second exemplary embodiment. FIG. 5A shows a state seen from the front, and FIG. 5B shows a state seen from the side. In FIG. 5, the details are omitted and only the part directly related to the essence of the present invention is taken out and shown in order to avoid complexity and difficulty in understanding, so the front view and the side view are not necessarily accurate. Does not match.

  The connector 502 has a large number of connection pins 505 inside. There are as many connection pins 505 as the number of wirings of the flexible wiring board 503, but only one overlapping pin is shown in the side view of FIG. Further, in the front view of FIG. 5A, only four of each of the both end sides are shown, but there are actually the same number of wires as the flexible wiring board 503 as described above. Further, the interval (pitch) at which the connection pins 505 are arranged is also approximate and not accurate. Furthermore, the connection pins 505 are not necessarily arranged in parallel in this way, but may be arranged in a so-called zigzag pattern (shifted back and forth alternately).

  The lower part of the connection pin 505 passes through a through hole 506 provided in the control board 501 and is connected to the control board 501. Note that the through hole 506 is shown only in the side view of FIG. 5B in order to simplify and understand the illustration, but it actually exists in the front view of FIG. 5A. In addition, priority is given to making the diameter of the through hole easy to see, and it is not accurate.

  The end of the flexible wiring board 503 is inserted from the fitting port 504 of the connector 502, and the lower surface of the flexible wiring board 503 is in contact with the contact portion 507 at the tip of the connection pin 505. This is an example in which the wiring pattern exists only on the lower surface of the flexible wiring board 503. In the example in which the wiring pattern exists on both surfaces of the flexible wiring board 503, the contact portion 507 at the tip of the connection pin 505 has a flexible wiring. It may be in contact with the upper surface of the substrate 503.

  There are members / mechanisms for press-contacting the flexible wiring board 503 and the connection pins 505, and lock members / mechanisms for fixing the flexible wiring board 503 and the connector 502 so as not to fall off. Is also omitted to avoid being complicated and difficult to understand.

  The other end (opposite side) of the flexible wiring board 503 is in pressure contact with each electrode on the panel via an anisotropic conductive sheet, but these are not directly related to the essence of the present invention. The illustration and description are omitted.

  In the plasma display device of the present invention, there is a gap 508 between the connector 502 and the control board 501 due to convenience when the connector 502 is attached to the control board 501, heat countermeasures during soldering, and other reasons. The component 550 is mounted on the control board 501 in front of (a front in the direction of FIG. 5A and the left in the side view of FIG. 5B).

  This component 550 is a component for generating various drive pulses on the control board 501, a component related to it, or any other component mounted on the other part of the control board 501. It doesn't matter.

  In FIG. 5, only one component 550 is shown, but the number of components 550 is not limited to one, and a plurality of components 550 may exist.

  Since this component 550 exists so as to close the gap 508, the flexible wiring board 503 is not erroneously inserted into the gap 508.

  Accordingly, the component 550 may have any size, number, and shape that can prevent the flexible wiring board 503 from being erroneously inserted into the gap 508, and the upper end of the component 550 is not necessarily the upper surface of the gap 508. However, there may be a new gap between the component 550 and the upper surface of the gap 508. However, the new gap should not be large enough to insert the flexible wiring board 503.

  As described above, in the plasma display device of the present invention, by mounting the component 550 on the control substrate 501 in front of the gap 508, the flexible wiring substrate 553 is erroneously added without adding or changing any new components. Thus, it is possible to prevent the flexible wiring board 553, the control board 501, or the connector 502 from being damaged or damaged.

  Furthermore, in the worst case, it is possible to prevent the flexible wiring board 503 from being shipped in a state where the flexible wiring board 503 is erroneously inserted into the gap 508.

(Embodiment 3)
Next, the plasma display apparatus in Embodiment 3 of this invention is demonstrated using drawing.

  The plasma display device according to the third embodiment of the present invention is the same as the plasma display device according to the first embodiment and the second embodiment of the present invention in many respects, and therefore, the third embodiment of the present invention. The description of the plasma display apparatus of the third embodiment is the same as those of the plasma display apparatus, and the description thereof will be omitted. Only the differences of the plasma display apparatus of the third embodiment of the present invention from these plasma display apparatuses will be described.

  FIG. 6 shows a schematic diagram of a state in which a connector 602 is mounted on the control board 601 and connected to the flexible wiring board 603 via the connector 602 in the plasma display device of the third embodiment. FIG. 6A shows a state seen from the front, and FIG. 6B shows a state seen from the side. In FIG. 6, the details are omitted and only the portion directly related to the essence of the present invention is taken out and shown in order to avoid complicated and difficult to understand. Therefore, the front view and the side view are not necessarily exactly one. I have not done it.

  The connector 602, the connection pin 605, the through hole 606, the fitting port 604, the connection pin 605, and the contact portion 607 are the same as those of the plasma display device according to the first embodiment and the second embodiment of the present invention. The description will be omitted.

A convex portion 640 exists on the connector 602 so as to fill a part of the gap 608, and is further in front of the gap 608 (front side in the direction of FIG. 6 (A) front view and left side in the direction of FIG. 6 (B) side view).

Similarly, in FIG. 6, only one protrusion 640 is shown, but the number of protrusions 640 is not limited to one, and a plurality of protrusions 640 may exist.

  Since the convex portion 640 exists so as to fill a part of the gap 608 and the component 650 is mounted on the control board 601 in front of the gap 608, the flexible wiring board 603 is mistakenly placed in the gap 608. Can be more reliably prevented from being inserted.

There is no need for contact, and there may be a gap. This is because even if there is a gap between the tip of the convex portion 640 and the control board 601, the presence of the component 650 can prevent the flexible wiring board 603 from being erroneously inserted into the gap 608.

  The convex portion 640 may fill not only a part of the gap 608 but also the whole, and the convex portion 640 is not necessarily the same size as the connector 602 in the depth direction of the connector 602. Not necessary. The convex portion 640 shown in FIG. 6 is only a part of the front side with respect to the depth direction of the connector 602.

In this case, the flexible wiring board 603 can be more reliably prevented from being erroneously inserted into the gap 608 without any change, and the flexible wiring board 603, the control board 601 or the connector 602 can be damaged or damaged. Can be prevented. Furthermore, in the worst case, it is possible to prevent the flexible wiring board 603 from being shipped in a state where the flexible wiring board 603 is erroneously inserted into the gap 608.

  ADVANTAGE OF THE INVENTION According to this invention, it can prevent that a flexible wiring board is accidentally inserted in the clearance gap between a connector and a control board, and can prevent a flexible wiring board, a control board, or a connector being damaged or damaged. .
