BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plasma display having an improved flexible printed circuit board for connecting a display panel and a driving circuit and a method for manufacturing the same, and more particularly to plasma for preventing migration of electrodes formed on the display panel. The present invention relates to a display and a manufacturing method thereof.

2. Description of the Related Art In a dot matrix type display device such as a liquid crystal display device and a plasma display, a circuit for driving row electrodes and column electrodes formed on a panel substrate is required, but a drive circuit is provided on the panel substrate. Since it is technically difficult to integrally mount the drive circuits, a configuration is generally used in which those drive circuits are mounted on another board and connected to the panel electrodes by jumper wires. As such a jumper wire, a flexible printed wiring board (FPC:
Flexible Print Circuit Board) is commonly used.

Recently, a method of mounting a circuit element on an FPC has also been used, and one FPC having more than 100 wires is used.

However, even if 240 FPCs are used, for example, about 8 FPCs are required to connect the column electrodes of the VGA class color display panel.

FIG. 6 is a schematic diagram showing a conventional general connection structure using an FPC.
The connection terminal 13 on the PC side is aligned using an alignment mark and bonded with an anisotropic conductive adhesive material. FIG. 7 is a partially enlarged view showing the details of FIG. 6 above.
It shows the terminal structure of the central portion.

In the conventional general FPC, a plurality of connection terminals 13 extending in the direction perpendicular to the one edge near the one edge are formed on the base film 16 at equal intervals. Further, alignment marks FR and FL are formed at positions sandwiching the plurality of connection terminals 13.

On the other hand, in the connection terminal on the display panel 14 side, a plurality of panel-side connection terminals 15 extending in the direction near the one edge and in the direction perpendicular to the edge are formed on the transparent substrate 17.

The FPC 11 as described above is attached to the display panel 14
When connecting to F, first, F detected by a method such as image recognition from the two alignment marks FR and FL on the FPC side.
The position of the connection terminal on the PC side is compared with the position of the connection terminal on the panel side similarly detected from the two alignment marks PR and PL on the panel side, and the positions are adjusted so that the intermediate positions of the two match. Display panel 1 with FPC11
4. Temporarily crimp to No. 4 at a relatively low temperature.

Similarly, other PFCs are also temporarily pressure-bonded, and then the plurality of FPCs 11 are collectively pressure-bonded to the display panel 14 at a higher temperature. At this time, if the size of the FPC 11 is accurate, the center line of the FPC-side connection terminal 13 and the center line of the panel-side connection terminal 15 can be aligned to allow connection without displacement. . However, misalignment occurs due to various factors such as manufacturing error, position detection accuracy, or misalignment due to difference in thermal expansion during pressure bonding. Therefore, in a practical FPC, the connection terminal width and the connection terminal pitch are determined in consideration of them.

FIG. 8 is a schematic view showing the positional relationship between the connection terminals when the size of the FPC 11 becomes larger than the design value,
FIG. 9 is a schematic diagram showing the positional relationship between the connection terminals when the size of the FPC 11 becomes smaller than the design value. In addition,
In FIG. 8 and FIG. 9, the connection terminal described at the right end is the connection terminal at the intermediate position of the alignment mark.

When the dimension of the FPC 11 becomes larger than the design value, as the distance from the middle position of the alignment mark increases, the connection terminal on the FPC side and the connection terminal pair on the panel side which should be originally aligned are as shown in FIG. The center line of the FPC-side connection terminal 13 is largely displaced from the center line of the panel-side connection terminal 15 in the direction away from the intermediate position. As a result, in the connection terminal pair near the intermediate position, the influence of the shift is small, so that the connection terminal 15 on the panel side is covered with the connection terminal 13 on the FPC side, but in the connection terminal pair separated from the intermediate position by a certain distance or more. , The connection terminal 15 on the panel side is an FPC
Side connecting terminal 13 and a connecting terminal pair further distant from the center position, the connecting terminal 15 on the panel side and the FPC
The connection terminal 13 on the side may not be connected.

On the other hand, when the size of the FPC 11 becomes smaller than the design value, the farther away from the intermediate position of the alignment mark, the connection terminal on the FPC side to be originally aligned-the connection terminal pair on the panel side is as shown in FIG. In addition, the center line of the FPC-side connection terminal 13 is largely displaced from the center line of the panel-side connection terminal 15 in the direction toward the intermediate position. As a result, in the connection terminal pair separated from the intermediate position by a certain distance or more, the connection terminal 15 on the panel side is connected to the connection terminal 1 on the FPC side.
In the connection terminal pair protruding from 3 and further separated from the center position, the panel-side connection terminal 15 and the FPC-side connection terminal 1
3 may not be connected.

When connecting a display panel of a plasma display and a drive circuit using such an FPC, there are the following two points which must be considered in particular.

The first problem is that the panel size of the plasma display panel is significantly larger than that of the liquid crystal display device and the like. Therefore, the cause of the positional shift is the influence of the positional shift due to the difference in thermal expansion during pressure bonding. The ratio is to increase.

The second problem is that when the electrodes of the plasma display panel are formed by a printing process, a silver paste is usually used as a conductive material, but an electric field is continuously applied to a connection terminal containing silver. In this case, deposition of dendritic silver called migration is likely to occur along the direction of the electric field, and if this deposition progresses beyond the limit, a short circuit between connecting terminals may occur.

This deposition phenomenon is particularly likely to occur in a device, such as a plasma display, which requires driving at a high voltage because it utilizes a discharge phenomenon, and the growth rate is also high.

As a remedy for this, the width of the connection terminals containing silver on the side of the plasma display panel where migration easily occurs is narrowed, and the width of the connection terminals on the FPC side using a conductive material that does not easily migrate is increased. A structure has been considered in which the electric field generated between the adjacent connection terminals is prevented from acting on the silver-containing connection terminal side by forming the silver-containing connection terminal on the panel side so as to cover it.

On the other hand, with respect to the connection terminals at positions where they are easily affected by the difference in thermal expansion, the width of the connection terminals is narrowed at the center and widened at both ends for the purpose of ensuring more overlap. A structure is known (Japanese Patent Laid-Open No. 7-6
5885). FIG. 10 is a schematic diagram showing a conventional wiring board described in Japanese Patent Application Laid-Open No. 7-65885.

The conventional wiring board 21 described in this publication
In the above, a plurality of terminals 2 are provided on the edge of the synthetic resin film.
2 is formed. The widths of the terminals 22 and the intervals between the terminals 22 are symmetrically increased from the central portion toward both ends with a constant proportional constant in consideration of thermal expansion of the synthetic resin film.

The conventional wiring board thus constructed is
The terminal 22 in the central portion is used as a reference for pressure bonding to the liquid crystal display panel. Since the synthetic resin film thermally expands during this crimping, the position of the terminal 22 shifts.
Since the width and the interval are set, each terminal 22 overlaps with a plurality of predetermined terminals provided on the liquid crystal display panel.

[0021]

However, in the conventional wiring board described in Japanese Patent Laid-Open No. 7-65885, although the thermal expansion of the synthetic resin film is taken into consideration, the actual dimensions and design values are If there is a displacement of the terminals or if there is a displacement of the terminals during crimping, sufficient overlap cannot be obtained between the terminals. This conventional wiring board is premised on application to a liquid crystal display device, but considering application to a plasma display, the progress of migration of panel electrodes caused when the overlap between terminals becomes insufficient. Since it is fast, it cannot be directly applied to a plasma display.

Further, Japanese Patent Application Laid-Open No. 10-294332 proposes a tape carrier package in which the width of the terminals is set wider from the central portion toward both ends on the premise of application to a liquid crystal display device. Even when the carrier package is applied to a plasma display, the migration of the panel electrode cannot be prevented.

The present invention has been made in view of the above problems, and provides a plasma display capable of preventing the migration of the panel electrode even when an error occurs in the dimension from the design value, and a manufacturing method thereof. The purpose is to

[0024]

The amount of misalignment can be reduced, and even if the center lines between the connection terminal pairs are misaligned due to dimensional deviation of the flexible printed wiring itself, the connection terminals of the flexible printed wiring can be used to connect the connection terminals of the display panel. Can be coated. Therefore, migration at the connection terminals on the panel side is prevented.

The method is characterized by including a step of aligning each other and temporarily pressure-bonding, and a step of permanently pressure-bonding the connection terminals respectively provided on the display panel side and the flexible printed wiring side.

In addition, it is preferable that the widths of the plurality of connection terminals on the flexible printed wiring side are increased in a geometric progression so that the connection terminals on both the display panel side and the flexible printed wiring side are adjacent to each other. It is preferable that the distance between the center lines between the mating connection terminals is increased by an arithmetic progression. Furthermore, it is even more preferred that the tolerances of each geometric series are equal to each other.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, a flexible printed circuit board (FPC) according to an embodiment of the present invention will be described.
A plasma display using the it board) and a method for manufacturing the same will be specifically described with reference to the accompanying drawings.

FIG. 1 is a schematic diagram showing the relationship between the FPC-side connection terminal array and the display panel-side connection terminal array to which the plasma display according to the embodiment of the present invention is connected, and FIGS. 3 is an enlarged view of the FPC-side connection terminal row, showing the details of the right end portion and the left end portion of FIG. 1, respectively.

The FPC 1 of this embodiment has wirings formed on a base film 6 made of polyimide, for example, and (2k) connection terminals are formed on the edges thereof. Alignment marks FR and FL for position detection are formed at both ends of the connection terminal row composed of the (2k) connection terminals. A slit 2 extending in the same direction as the connection terminals is formed on the base film 6 at the center of the connection terminal row. In this embodiment, k connection terminals 3R-1 to 3R are provided between the alignment mark FR and the slit 2.
-K is arranged, the alignment mark FL and the slit 2
, And the example in which k connection terminals 3L-1 to 3L-k are arranged, the number of connection terminals arranged between the slit and both alignment marks is different. Good.

In FIG. 1, the connection terminals on the FPC side appear to have the same width, but as shown in FIG. 2, the distance between the alignment mark FR and the slit 2 increases as the distance from the alignment mark FR increases. , The width of the connection terminal is wide. Specifically, the width of the connection terminal 3R-1 closest to the alignment mark FR is W, the width of the connection terminal 3R-2 next to the alignment mark FR is (W + α), and the connection terminal 3R next to the alignment mark FR. The width of -3 is (W + 2α), the width of the connection terminal 3R-4 next to the alignment mark FR is (W + 3α), the width of the connection terminal 3R-5 next to the alignment mark FR is (W + 4α),
The width of the connection terminal 3R-6 next to the alignment mark FR is (W + 5α), the width of the connection terminal 3R-7 next to the alignment mark FR is (W + 6α), ...

Similarly, as shown in FIG. 3, between the alignment mark FL and the slit 2, the width of the connecting terminal 3L-1 closest to the alignment mark FL is W, and the connecting terminal 3L closest to the alignment mark FL is next. The width of -2 is (W
+ Α), the connection terminal 3 next to the alignment mark FL
The width of L-3 is (W + 2α), then the alignment mark F
The width of the connection terminal 3L-4 close to L is (W + 3α), the width of the connection terminal 3L-5 next to the alignment mark FL is (W + 4α), and the width of the connection terminal 3L-6 next to the alignment mark FL is ( W + 5α), and the width of the connection terminal 3L-7 next to the alignment mark FL is (W + 6α),
It has become.

That is, the widths of the connection terminals on the FPC side on both sides of the slit 2 are increased by arithmetic progression.

Further, the distance between the center lines of the connection terminals on the FPC side at the above-mentioned edge is determined by the alignment marks FR and FL.
It becomes larger as it moves away from. In particular,
Between the alignment mark FR and the slit 2, the center line interval between the connection terminals 3R-1 and 3R-2 is P, the center line interval between the connection terminals 3R-2 and 3R-3 is (P + α),
The center line distance between the connection terminals 3R-3 and 3R-4 is (P +
2α), ..., Between the alignment mark FL and the slit 2, the center line interval between the connection terminals 3L-1 and 3L-2 is P, and the center line between the connection terminals 3L-2 and 3L-3. The interval is (P + α), and the connection terminals 3L-3 and 3L-
The center line interval between 4 is (P + 2α), ...

That is, the center line intervals of the connection terminals on the FPC side on both sides of the slit 2 also increase in the arithmetic series.

On the other hand, in the display panel 4, (2k) panel-side connection terminals 5R-1 to 5R-k and 5L-1 to 5L-k which extend in the direction near the one edge and in the direction perpendicular to the one edge are provided.
Are formed on a transparent substrate 7 such as a glass substrate. The width of these connection terminals on the panel side is constant at w. This width w is narrower than the width W of the connection terminals 3R-1 and 3L-1 having the smallest width among the connection terminals on the FPC side.

As shown in FIG. 2, the alignment mark P
The center line distance between the connection terminal 5R-1 closest to R and the connection terminal 5R-2 next next is P, and the center line distance between the connection terminal 5R-2 and connection terminal 5R-3 next next is (P +
α), the connection terminal 5R-3 and the next closest connection terminal 5R-
4 is (P + 2α), and the center line distance between the connection terminal 5R-4 and the next closest connection terminal 5R-5 is (P + 2α).
3α), connection terminal 5R-5 and the next closest connection terminal 5R
The center line distance from -6 is (P + 4α), and the connection terminal 5R-6
And the center line distance between the connection terminal 5R-7 and the next closest terminal is (P
+ 5α).

Further, as shown in FIG. 3, the center line interval between the connection terminal 5L-1 closest to the alignment mark PL and the connection terminal 5L-2 next next is P, and the connection terminal 5L-2.
The distance between the center lines of the connection terminal 5L-3 and the next closest connection terminal 5L-3 is (P
+ Α), connection terminal 5L-3 and the next closest connection terminal 5L
-4 is (P + 2α), and the connection terminal 5L-4
And the center line interval between the connection terminal 5L-5 and the next closest terminal is (P
+ 3α), connection terminal 5L-5 and the next closest connection terminal 5
The center line distance from L-6 is (P + 4α), and the connection terminal 5L-
The center line interval between 6 and the next closest connection terminal 5L-7 is (P + 5α).

That is, the distance between the center lines of the connection terminals on the panel side on both sides of the slit 2 also increases in the arithmetic series. Then, the tolerance of the arithmetic series constituted by the width of the connection terminal on the FPC side, the tolerance of the arithmetic series constituted by the center line spacing of the connection terminals on the FPC side and the arithmetic series constituted by the spacing of the connection terminals on the panel side. The tolerances are equal to each other at α.

The distance between the alignment marks PR and PL is equal to the distance between the alignment marks FR and FL, and the distance between each alignment mark and the connection terminal closest to it is uniform.

The connection terminal on each FPC side is, for example, C
The u foil is plated with gold, and the connection terminal on each panel side is formed of, for example, an ultraviolet-sensitive Ag paste.

When the number of FPC side connection terminals and panel side connection terminals is 256, for example, the value of W is 110 μm.
The values of m and w are 70 μm, the value of P is 320 μm, and the value of α is 1 μm. Therefore, the widest panel side connection terminal interval is 447 μm, and the widest FPC electrode width is 237.
μm.

Next, a method of mounting the FPC 1 of this embodiment having the above-described structure on the display panel 4 will be described. First, the positions of the alignment mark FR and the alignment mark PR at one end of the FPC and the panel are made to coincide with each other, and the vicinity thereof is partially pressure-bonded and fixed with an anisotropic conductive adhesive so as to prevent misalignment in a later process. Next, the alignment marks FL and PL at the other end are similarly aligned and pressure-bonded and fixed. After similarly crimping other FPCs, all the connecting terminals of the plurality of FPCs 1 are collectively collectively press-bonded to the connecting terminals of the display panel 4. At this time, if the dimensions of the FPC 1 are accurate, the connection terminals 3R-n (1 ≦ n ≦
The center line of k) and the center line of the connection terminal 5R-n on the panel side are aligned, and the center line of the connection terminal 3L-n on the FPC side and the center line of the connection terminal 5L-n on the panel side are aligned. Each FP
Since the width of the connection terminal on the C side (W or more) is wider than the width w of the connection terminal on the panel side, all the connection terminals on each panel side are FP.
The connection terminal on the C side is completely covered. In other words, the upper surface of the panel-side connection terminal that faces the FPC 1 and the side surface that faces the adjacent panel-side connection terminal are covered with the FPC-side connection terminal.

In this way, the FPC 1 displays the display panel 4
In the plasma display configured by being attached to the panel, since the connection terminals on the panel side are completely covered by the connection terminals on the FPC side, migration at the connection terminals on the panel side is prevented.

However, as described above, it is extremely difficult to obtain the FPC 1 having no dimensional error. Then F
The case where the size of the PC 1 becomes larger than the design value and the case where the size becomes smaller than the design value will be described respectively. FIG. 4 is a schematic diagram showing the positional relationship between the connection terminals when the size of the FPC 1 is larger than the design value, and FIG. 5 is the schematic relationship between the connection terminals when the size of the FPC 1 is smaller than the design value. It is a schematic diagram which shows.

When the size of the FPC 1 becomes larger than the design value, the alignment marks FR and PR can be obtained from the slit 2.
On the side, as the distance from the alignment marks FR and PR increases, the center line of the FPC-side connection terminal 3R-n is closer to the panel side with respect to the FPC-side connection terminal 3R-n and the panel-side connection terminal 5R-n that should originally be aligned. From the center line of the connection terminal 5R-n in the direction away from the alignment marks FR and PR. However, in this embodiment,
As shown in FIG. 4, as the distance from the alignment mark FR increases, the width of the connection terminals on the FPC side is set wider, so that even if the deviation between the connection terminals becomes large, the connection terminals 5R-n on the panel side will be Both ends are connection terminals 3R-n on the FPC side
Within the width of. Therefore, the connection terminal 5R-n on the panel side is covered with the connection terminal 3R-n on the FPC side after the main pressure bonding.
That is, the upper surface and both side surfaces of the panel-side connection terminal are completely covered with the FPC-side connection terminal. Further, since the slit 2 is formed in the base film 6, even if the alignment marks are temporarily pressure-bonded, the thermal expansion of the base film 6 in the main pressure-bonding proceeds toward the slit 2. For this reason, no misalignment occurs between the temporarily-aligned alignment marks. 4 shows only the alignment marks FR and PR sides from the slit 2, but also on the alignment marks FL and PL sides from the slit 2, the panel-side connection terminal 5L-n similarly has the FPC-side connection terminal 3L after the main pressure bonding. -N. Therefore, also in this case, migration of the connection terminals on the panel side in the plasma display is prevented.

On the other hand, when the size of the FPC 1 becomes smaller than the design value, the more the distance from the alignment marks FR and PR is closer to the alignment marks FR and PR than the slit 2, the more the connection terminals 3R- on the FPC side that should be originally aligned.
n and the panel-side connection terminal 5R-n, the center line of the FPC-side connection terminal 3R-n is the panel-side connection terminal 5R.
A large deviation from the center line of −n toward the alignment marks FR and PR. However, in this embodiment, as shown in FIG. 5, the width of the connection terminal on the FPC side is set to be wider as the distance from the alignment mark FR increases. Both ends of the connection terminal 5R-n on the FPC side are connected to the connection terminal 3R on the FPC side.
-Within the width of n. Therefore, the connection terminal 5R- on the panel side
After the main pressure bonding, n is covered with the connection terminal 3R-n on the FPC side. That is, the top surface and both side surfaces of the connection terminal on the panel side are FP
It is completely covered by the connection terminal on the C side. Further, since the slit 2 is formed in the base film 6, even if the alignment marks are temporarily pressure-bonded, the thermal expansion of the base film 6 in the main pressure-bonding proceeds toward the slit 2. For this reason, no misalignment occurs between the temporarily-aligned alignment marks. FIG. 5 shows only the alignment marks FR and PR sides from the slit 2, but also on the alignment marks FL and PL sides from the slit 2, the panel-side connection terminals 5L-n similarly have the FPC-side connection terminals 3L after the main pressure bonding. -N. Therefore, also in this case, migration of the connection terminals on the panel side in the plasma display is prevented.

[0048]

As described in detail above, according to the present invention,
Since the width of the connection terminals that make up the connection terminal row is gradually increased from the alignment marks provided at both ends of the connection terminal row toward the slits, the flexible printed wiring itself has a dimensional error and is designed to be compatible. Even if the center lines are misaligned between the pair of connection terminals that form the connection terminals provided on the display panel side by the connection terminals provided on the flexible printed wiring side without causing misalignment between the temporarily pressured alignment marks. Can be coated. Therefore,
Even if Ag is contained in the connection terminal on the display panel side to generate a high electric field peculiar to the plasma display, migration in the connection terminal can be prevented.
