DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to an inspection apparatus for inspecting whether or not an inspection object provided with a flexible wiring board operates normally. Further, the present invention relates to an inspection method for inspecting whether or not the liquid crystal display device performs a display operation normally. In particular, the present invention relates to an inspection method for a liquid crystal display device having a structure to which a flexible wiring board such as an FPC is connected.

[0002]

2. Description of the Related Art In the present industrial field, various electronic devices having a flexible wiring board are known. For example, considering a liquid crystal display device as an electronic device, a flexible wiring board is often conductively connected to a transparent substrate constituting a liquid crystal panel. This liquid crystal display device is a display device that modulates light by controlling the orientation of liquid crystal, thereby displaying visible information such as characters, etc. This liquid crystal display device usually has an external circuit. A flexible wiring board is provided for transmitting and receiving signals to and from the outside, or for receiving power supply from outside.

When manufacturing such a liquid crystal display device or other electronic equipment, it is necessary to check whether the completed liquid crystal display device or the like operates normally. As an inspection apparatus for performing such an inspection, conventionally, a plurality of inspection probes are prepared as inspection terminals, and the inspection is performed in a state where the electrode terminals of the flexible wiring board are in contact with the tips of the probes. There is a device like this. In general, in this apparatus, a method of pressing the flexible wiring board against the inspection probe using a pressing member is often adopted in order to ensure the contact between the inspection probe and the electrode terminal of the flexible wiring board.

[0004]

By the way, considering a liquid crystal display device, for example, the display surface of visible information and the electrode terminals of the flexible wiring board face each other, as in a reflective liquid crystal display panel. Some are configured. When an inspection is performed on this type of liquid crystal display device, the electrode terminals of the flexible wiring board are located on the back side when viewed from the operator because the display surface must be directed toward the operator.

When an inspection is performed on such a liquid crystal display device by using a pressing member, the inspection probe is hidden behind the flexible wiring board when viewed from an operator, and furthermore, the inspection probe is hidden behind the flexible wiring board. The electrode terminal portion is hidden behind the pressing member. Therefore, when the electrode terminals of the flexible wiring board are brought into contact with the inspection probe, it is not known whether or not both are correctly aligned. If accurate alignment is not performed, there is a problem that a correct inspection cannot be performed. In particular, since the flexible wiring board is easily deformed, the possibility that the electrode terminals of the wiring board are removed from the inspection probe is considered to be considerably higher than that of a wiring board having high rigidity. Therefore, especially with respect to the flexible wiring board, there was anxiety in the alignment between the electrode terminal and the inspection probe. In a transmissive liquid crystal panel, as shown in FIG. 7, a flexible wiring board is connected to opposing surfaces of upper and lower substrates, and one of them is always located on the back side when viewed from an operator.

The present invention has been made in view of the above problems, and has an inspection apparatus of the type in which an inspection is performed by contacting an electrode terminal on a wiring board side with an inspection terminal on the back side of a flexible wiring board. In view of the above, an object of the present invention is to provide an inspection apparatus that can always accurately contact an electrode terminal on a wiring board side and an inspection terminal.

[0007]

SUMMARY OF THE INVENTION An inspection apparatus according to the present invention is an inspection apparatus for inspecting the operation of an object to be inspected provided with a flexible wiring board having electrode terminals formed thereon. And a pressing member that presses the flexible wiring board against the inspection terminal. The inspection device includes a pressing side mark provided on the pressing member, a guide unit for guiding the pressing member such that the pressing side mark has a fixed positional relationship with respect to the inspection terminal, and And a mark to be inspected provided on the flexible wiring board in a fixed positional relationship with respect to the electrode terminal. Further, the inspection device according to the present invention is an inspection device for inspecting the operation of an object to be inspected provided with a flexible wiring board having an electrode terminal formed on one surface, wherein the inspection terminal contacted with the electrode terminal, A pressing member that presses the flexible wiring board against the inspection terminal from the side opposite to the one surface of the flexible wiring board, a pressing mark provided on the pressing member, and the pressing mark is relative to the inspection terminal. A guide means for guiding the pressing member so as to have a fixed positional relationship with the electrode terminals, and a test mark provided on the flexible wiring board with a fixed positional relationship with respect to the electrode terminals, The flexible wiring board is pressed against the inspection terminal by using the pressing member in a state where the pressing side mark and the inspection side mark are aligned.

According to this inspection apparatus, the position of the electrode terminal of the flexible wiring board can be accurately matched with the inspection terminal by aligning the mark to be inspected of the flexible wiring board with the mark of the pressing side of the pressing member. Therefore, a highly reliable inspection can be performed.

The mark to be inspected formed on the flexible wiring board can be formed by an arbitrary pattern. For example, the mark can be visually recognized when the flexible wiring board on which the electrode terminals are formed is viewed from the opposite surface of the electrode terminals. It can be the electrode terminal itself. To explain this more specifically, the following specific example can be considered. First, if the flexible wiring board is formed of a transparent or light transmissive member, and an electrode terminal is formed on one of the surfaces, a rear image of the electrode terminal can be seen through the opposite surface. Therefore, the rear surface image of the electrode terminal can be used as a mark to be inspected. The other one is that, regardless of whether the flexible wiring board is transparent or opaque, when an electrode terminal is formed on one surface of the flexible wiring board, the other surface corresponds to the electrode terminal on the opposite surface. An uneven pattern may be formed. Therefore, the concavo-convex pattern corresponding to the electrode terminal itself can be used as a mark to be inspected.

Next, the pressing mark can be provided at an arbitrary position of the pressing member, but is preferably provided on the side surface of the pressing member, particularly on the following side surface. That is, when the pressing member presses the electrode terminal portion of the flexible wiring board, many portions of the flexible wiring board project outside the pressing member. It is desirable to provide a push mark on the side surface of the member.

Next, the inspection terminal can have any configuration as long as it has a structure that can individually contact the individual electrode terminals. For example, it can be constituted by a needle-like terminal called a so-called inspection probe or another planar terminal. When a planar terminal is used, anisotropic conductive rubber must be provided on the planar terminal, and the electrode terminal of the flexible wiring board and the planar terminal must be conductively connected through the anisotropic conductive rubber. Is desirable.

The anisotropic conductive rubber is a conductive rubber having conductivity in the thickness direction but not in a plane direction perpendicular to the thickness direction. Processing such as dispersing in rubber or embedding a conductive fine wire in rubber gives conductivity in a single thickness direction.

Next, the pressing member may be transparent,
Alternatively, it may be opaque. However, if it is set to transparent, the electrode terminal portion of the flexible wiring board can be visually recognized through the transparent pressing member,
It is desirable that the pressing member be transparent. Next, the inspection apparatus according to the present invention can be applied to various inspection objects provided with a flexible wiring board, and such an inspection object may be any circuit component, a liquid crystal display device, or the like. .

Next, a method for inspecting a liquid crystal display device according to the present invention is an inspection method for inspecting a display operation of a liquid crystal display device having a flexible wiring board on which electrode terminals are formed, wherein a pressing member is used. This is an inspection method in which an electrode terminal of the flexible wiring board is connected to the inspection terminal by pressing the flexible wiring board against the inspection terminal to perform an inspection. In this inspection method, (1) the pressing side mark is provided on the pressing member, and (2) the inspection side mark is provided on the flexible wiring board so as to have a fixed positional relationship with the electrode terminal of the flexible wiring board. And (3) pressing the flexible wiring board against the inspection terminal using the pressing member in a state where the push-side mark and the inspection-side mark are aligned.

This inspection apparatus is mounted on a base 2 on which a liquid crystal display device 1 is mounted, a plurality of inspection probes 4 as inspection terminals fixed and installed in a long hole 3 formed in the base 2, and is mounted on the base 2. It has two guide rods 6 and a pressing member 7 supported by the guide rods 6. On the base 2
A pin 5 for positioning the liquid crystal display device 1 is provided.

The liquid crystal display device 1 includes a liquid crystal panel 9 and an FPC (Flexible Printed Circuit) 11 as a flexible wiring board connected to the liquid crystal panel 9. The liquid crystal panel 9 has a pair of glass substrates 8a and 8b stacked and bonded to each other, and a liquid crystal is sealed in a gap formed between the substrates, that is, a so-called cell gap. In the liquid crystal panel 9, the outer surface of the upper substrate 8a in the figure serves as a display surface 9a for displaying visible information such as characters.

The FPC 11 is an ACF (Anisotropic).
It is conductively connected to the end of the lower substrate 8b using a bonding agent such as a conductive film (anisotropic conductive film). This FP
C11 has a plurality of electrode terminals 12 formed on the back side (bottom side in the figure) of the tip. These electrode terminals are connected to a transparent electrode (not shown) formed inside the liquid crystal panel 9. The liquid crystal display device 1 is connected to an appropriate electronic device (not shown)
When used as an element for displaying a visible image, a liquid crystal drive signal or the like supplied from an external circuit (not shown) included in the electronic device is passed through these electrode terminals 12. The signal is transmitted to each pixel electrode in the liquid crystal panel 9. As a result, a visible image such as a character is displayed on the display surface 9a of the liquid crystal panel 9.

In this embodiment, the display surface 9 of the liquid crystal panel 9
a faces upward in the figure, and the electrode terminals 12 of the FPC 11 face downward in the figure. That is, the display surface 9a
And the electrode terminal 12 are set so as to face the opposite sides. This is the liquid crystal display device 1 according to the present embodiment.
This is a structure for satisfying the requirements from the internal structure of the electronic device using the.

In the present embodiment, the FPC 11 is formed of a material having optical transparency. The light transmissive property is not completely transparent but has a slight coloring but a property that the opposite side can be seen through. Therefore,
The electrode terminals 12 formed on the back side of the FPC 11
It can be visually recognized from the front side of C11, that is, the display surface 9a side of the liquid crystal panel 9. A guide hole 17 is formed at an appropriate position of the FPC 11. When the liquid crystal panel 9 is placed on the base 2, the guide holes 17, 17
Are fitted to the positioning pins 5 and 5 on the base 2 to position the FPC 11 with respect to the inspection probe 4.

Each of the plurality of inspection probes 4 is formed by a needle-like electrode terminal. The output terminals of the display test circuit 13 are connected to these test probes 4. The display test circuit 13 generates a liquid crystal drive signal for experimentally displaying appropriate characters, graphics, and other visible images on the display surface 9 a of the liquid crystal panel 9, and sends the signal to each inspection probe 4. Output.

While being guided by the guide rods 6, 6, the pressing member 7 can translate in a direction approaching or moving away from the base 2 as shown by an arrow AA '. However,
In the natural state, a force is applied by a spring or other elastic member 14 to move in the direction A ′. The pressing member 7 is formed of, for example, a transparent acrylic resin. The pressing member 7 is formed of a rectangular parallelepiped flat plate, and has a flat bottom surface. The flat bottom surface functions as a pressing surface for pressing the terminal portion of the FPC 11.

On the front side surface 7a of the pressing member 7, a plurality of linear marks 16 serving as pressing side marks are provided. These linear marks 16 have a fixed positional relationship with respect to the inspection probe 4. More specifically, the liquid crystal display device 1 to be inspected is placed at a predetermined inspection position on the base 2, and each electrode terminal 12 at the distal end of the FPC 11 is accurately aligned with the distal end of each inspection probe 4. And
When the distal end portion of the FPC 11 in this state is pressed by the pressing member 7, the position of each linear mark 16 is set so as to match the position of the back image of each electrode terminal 12.

The operation of the inspection apparatus having the above configuration will be described below.

First, the liquid crystal panel 9 of the liquid crystal display device 1 to be inspected is placed on the base 2 with its display surface 9a facing upward.
And guide holes 17, 17 of FPC 11.
Into the pins 5 and 5 on the base 2. Thereby, F
The electrode terminal of the PC 11 is positioned so as to cover the inspection probe 4. At this time, the electrode terminals 12 of the FPC 11
Are oriented in the direction of the base 2, so that their electrode terminals 12 cannot be directly recognized from above. However, in the present embodiment, since the FPC 11 has optical transparency, the rear image of the electrode terminal 12 can be visually recognized from above the base 2. This rear image is used as a mark to be inspected for specifying the position on the FPC 11 side.

After the liquid crystal display device 1 is placed at a predetermined inspection position on the base 2, the pressing member 7 is moved parallel to the base 2 as shown by an arrow A against the elastic force of the elastic member 14. FPC covering the inspection probe 4 as shown in FIG.
11 electrode terminal portions are pressed from above. By this pressing operation, each electrode terminal 12 of the FPC 11 individually comes into contact with the tip of the inspection probe 4. At this time, the operator performing the inspection determines whether or not each of the linear marks 16 provided on the pressing member 7 exactly matches each of the back images of the electrode terminals 12 that can be visually recognized through the FPC 11. It is confirmed, and if they match, the operation is continued as it is, and if they do not match, the FPC 11 is appropriately shifted in the plane direction to adjust the position. The fact that the straight line mark 16 exactly matches the rear surface image of the electrode terminal 12 means that each electrode terminal 12 accurately contacts the individual inspection probe 4.

In this way, when the electrode terminals 12 of the FPC 11 and the individual inspection probes 4 come into accurate contact with each other, the liquid crystal drive signal for inspection supplied from the display test circuit 13 is accurately applied to each electrode terminal 12 in FIG. Transmitted to
A predetermined visible image for inspection is displayed on the display surface 9a of the liquid crystal panel 9. If this visible image is normally displayed, the liquid crystal display device 1 to be inspected is determined to be good. On the other hand, if any defect is found in the displayed visible image, the liquid crystal display device 1 is turned off. It is determined that the product is defective.

In the present embodiment, as described above, the position of each electrode terminal 12 of the FPC 11 is adjusted according to the pressing side mark 16 of the pressing member 7.
Can always always accurately contact the inspection probe 4. Therefore, a highly reliable inspection can be performed.

(Second Embodiment) FIG. 2 shows another embodiment of the inspection apparatus and the inspection method according to the present invention. This embodiment differs from the previous embodiment shown in FIG. 1 in that the inspection terminals are modified. More specifically,
Instead of fixedly disposing a needle-like inspection probe on the base 2, an inspection terminal is constituted by a plurality of planar terminals 19 formed on a printed circuit board 18. Further, among the planar terminals 19, the electrode terminals 12 of the FPC 11 are provided.

1 is provided.

As shown in FIG. 4, the anisotropic conductive rubber 21 is formed by dispersing conductive particles 22 in an electrically insulating rubber 23, and has conductivity in the thickness direction BB. However, it has conductive anisotropy, ie, has no conductivity in the plane direction CC.

In FIG. 2, the liquid crystal display device 1 to be inspected is
When the inspection is performed, the electrode terminal portion of the FPC 11 is pressed against the anisotropic conductive rubber 21 by the pressing member 7. Also in this case, as shown in FIG. 3, the back surface image of each electrode terminal 12 of the FPC 11 is
To match.

(Third Embodiment) FIG. 5 shows a modification of the push-side mark provided on the pressing member 7. The push-side mark shown here is also formed by a plurality of straight-line marks 26, but these straight-line marks 26 are not provided on all of the back images of the electrode terminals 12 of the FPC 11, but are provided on these electrode terminals 12. On the other hand, a straight line mark 26 is provided every other mark.

(Fourth Embodiment) FIG. 6 shows a modified example of the push-side mark provided on the pressing member 7 and the inspection-side mark provided on the FPC 11. The push side mark shown here is 2
It is constituted by the straight line marks 36. The mark to be inspected is formed as a linear mark 32 on the front side of the FPC 11, that is, on the display surface 9 a side of the liquid crystal panel 9, separately from the electrode terminals 12. These linear marks 32 are formed with a fixed positional relationship with respect to each electrode terminal 12, and therefore, these linear marks 32
If the position of the FPC 11 is adjusted so as to coincide with the straight line mark 36, each electrode terminal 12 necessarily coincides exactly with the inspection probe 4 or the planar inspection terminal 19 (FIG. 2).

(Fifth Embodiment) FIG. 7 shows still another embodiment of the inspection apparatus and the inspection method according to the present invention. The inspection device shown here targets the liquid crystal display device 31 for inspection. The liquid crystal display device 31 has a pair of transparent substrates 33 and 34 which are adhered to each other by a sealing member 39 formed in a rectangular ring shape and face each other. In the figure, the transparent substrate 34 is located on the near side, and the transparent substrate 33 is located on the back side of the transparent substrate 34. Liquid crystal is sealed in a gap formed between these transparent substrates, a so-called cell gap.

A plurality of pixel electrodes 35 and a plurality of lead electrodes 3 are provided on the surface of the transparent substrate 33 on the cell gap side.
7 is formed. As shown in FIG. 8, the individual pixel electrodes 3
5 and the lead electrode 37, M
An IM device (Metal-Insulator-Metal: metal-insulator-metal) 38 is provided. As is well known, the MIM element 38 is formed by forming an anodic oxide film as an insulating film on a first metal extending from the lead electrode 37 and further forming a second metal thereon. It is formed in a metal laminated structure. The pixel electrode 35 is formed on the second metal.

In FIG. 7, on the cell gap side surface of another transparent substrate 34 facing the transparent substrate 33,
R (red), G (green), and B (blue) color filters (not shown) are formed, and a counter electrode 41 is further formed thereon. As shown in FIG. 8, each opposing electrode 41 is arranged so as to oppose each pixel electrode 35, and the opposing portions constitute individual pixels for liquid crystal display.

In FIG. 7, each lead electrode 37 extends to an end of the transparent substrate 33 and is connected to an external connection terminal 42. A driver IC 43 is mounted on a portion of the transparent substrate 33 where the external connection terminals 42 are formed. This mounting is performed by using a bonding material between the driver IC 43 and the transparent substrate 33, for example, an ACF (Anisotropic Conic).
This is performed by sandwiching a conductive film (an anisotropic conductive film). Further, the counter electrode 41 formed on the other transparent electrode 34 extends to the end of the transparent substrate 34 and is connected to the external connection terminal 44. Similarly to the driver IC 43, the driver IC 43 is also provided on the portion of the transparent substrate 34 where these external connection terminals 44 are formed.
45 are implemented.

At the end of the transparent substrate 33, a driver IC 4
FPC 46 for supplying power and signals to the ACF 3
Conductive connection is made by using such as. An FPC 47 for supplying power and a signal to the driver IC 45 is conductively connected to an end of the other transparent substrate 34 using an ACF or the like. These FPCs 46 and 47 have electrode terminals 52 on one of the front and back surfaces. Now, the transparent substrate 3
If the outer surface (front surface in the drawing) of the FPC 4 is a display surface 34a for displaying visible information, the electrode terminals 52 of the FPC 47 connected to one of the transparent substrates 34 face the same direction as the display surface 34a, The electrode terminals 52 of the FPC 46 connected to the other transparent substrate 33 face in the direction opposite to the display surface 34a.

When inspecting the display state of the liquid crystal display device 31 having the above-described configuration, the FPCs 46 and 47 are set with the display surface 34a facing the operator.
The inspection probe 54 is brought into contact with the electrode terminal 52 of the above, and an inspection signal is supplied to each counter electrode 41 and each pixel electrode 35. At this time, since the electrode terminals 52 of the FPC 47 connected to the transparent substrate 34 face the same direction as the display surface 34a, that is, the direction of the worker, it is not possible to bring the inspection probe 54 into contact with those electrode terminals. It can be done relatively easily.

On the other hand, with respect to the FPC 46 connected to the other transparent substrate 33, the electrode terminals 52 of the FPC 46 are in the opposite direction to the display surface 34a, that is, when viewed from the operator.
, It is very difficult to bring the inspection probe 54 into contact with those electrode terminals 52 accurately.
Therefore, it is desirable to apply the inspection device according to the present invention as shown in FIGS.

For example, if the inspection is performed on the FPC 46 shown in FIG. 7 using the inspection apparatus shown in FIG. 1, each of the linear marks 16 provided on the pressing member 7
Of the back image of each electrode terminal 52 that can be visually recognized through
Check if they match exactly one by one, and if they match, continue the operation as is, otherwise, check the FPC
46 is appropriately shifted in the plane direction to adjust the position.
Each electrode terminal 52 is brought into accurate contact with an individual inspection probe 54. In this state, a liquid crystal drive signal for inspection is supplied from the display test circuit 13, and visible information is displayed on the display surface 34a to perform the inspection.

(Other Embodiments) Although the present invention has been described with reference to the preferred embodiments, the present invention is not limited to the embodiments, and various modifications may be made within the technical scope described in the claims. Can be modified.

For example, in the above-described embodiment, the inspection apparatus according to the present invention is used for inspecting a liquid crystal display device. In addition, circuit components having an arbitrary circuit configuration and various other An electronic device or the like can be the inspection object.

The shape of the pressing mark provided on the pressing member 7 is not limited to a linear shape, but may be any shape. Further, the position at which the push-side mark is provided is not limited to the front side surface 7a of the pressing member 7, but may be provided at any other position. However, in consideration of the workability of the inspection, it is desirable to provide a push-side mark on the front side surface 7a adjacent to the FPC 11 to be inspected.

The mark to be inspected provided on the flexible wiring board such as the FPC 11 is not limited to the rear surface image of the electrode terminal 12. For example, the electrode terminal 1 is provided on one surface of the FPC 11.
When 2 is formed, a slight uneven pattern corresponding to the electrode terminal 12 may be formed on the opposite surface of the FPC 11 due to the formation. Therefore, in such a case, the concavo-convex pattern generated corresponding to each electrode terminal 12 can be used as a mark to be inspected.

The terminal accurately matches the inspection terminal, and thus a highly reliable inspection can be performed. Therefore, for example, when a liquid crystal display device in which the display surface of the liquid crystal panel and the electrode terminals of the flexible wiring board are located on opposite sides of the front and back is to be inspected, the wiring board is placed on the back side of the flexible wiring board. Even when the inspection is performed by contacting the side electrode terminal and the inspection terminal, the wiring board side electrode terminal and the inspection terminal can always be accurately contacted.

According to the second aspect of the present invention, if the electrode terminals are formed on the flexible wiring board, the mark to be inspected is automatically created, so that the process is simplified. In addition, since the mark to be inspected is the electrode terminal itself, the positional correlation between the mark to be inspected and the electrode terminal always maintains a fixed relationship accurately, and therefore, a more reliable inspection. Can be.

According to the inspection apparatus of the third aspect, since the position can be determined in a state where the pressing side mark and the inspection side mark are closest to each other, the inspection accuracy is improved.

According to the inspection apparatus of the sixth aspect, the contact portion between the electrode terminal and the inspection terminal can be seen from the outside through the transparent pressing member, so that the inspection workability is improved.
