The present invention relates to a plasma display device, and more particularly, to a plasma display device for reducing a noise signal by improving a cable connection structure.

In general, a panel of a plasma display device has a partition wall formed between an upper substrate and a lower substrate as one unit cell, and each cell includes neon (Ne), helium (He), or a mixture of neon and helium (Ne + He). Is filled with a main discharge gas such as) and a small amount of xenon. When discharged by a high frequency voltage, the inert gas generates vacuum ultraviolet rays and emits phosphors formed between the partition walls to realize an image. Such a plasma display panel has a spotlight as a next generation display device because of its thin and light configuration.

1 illustrates a panel structure of a general plasma display device. As shown, the plasma display panel is coupled in parallel with the upper substrate 100, which is the display surface on which the image is displayed, and the lower substrate 110 forming the rear surface, with a predetermined distance therebetween.

The upper substrate 100 is made of a scan electrode 101 and a sustain electrode 102, that is, a transparent electrode (a) formed of a transparent ITO material and a metal material to mutually discharge and maintain light emission of the cells in one discharge cell. The scan electrode 101 and the sustain electrode 102 provided as the bus electrode b are formed in pairs. The scan electrode 101 and the sustain electrode 102 are covered by one or more dielectric layers 103 which limit the discharge current and insulate the electrode pairs, and the magnesium oxide top surface of the dielectric layer 103 to facilitate the discharge conditions. A protective layer 104 on which (MgO) is deposited is formed.

The lower substrate 110 is arranged such that a plurality of discharge spaces, that is, barrier ribs 111 of a stripe type (or well type) for forming discharge cells are maintained in parallel. In addition, a plurality of address electrodes 112 which perform address discharge to generate vacuum ultraviolet rays are arranged in parallel with the partition wall 111. On the upper side of the lower substrate 110, R, G, and B phosphors 113 which emit visible light for image display during address discharge are coated. A white dielectric 114 is formed between the address electrode 112 and the phosphor 113 to protect the address electrode 112 and reflect visible light emitted from the phosphor 113 to the upper substrate 100.

An electrode array structure of a panel of the plasma display device having such a structure will be described with reference to FIG. 2.

2 is a diagram illustrating an electrode array structure in a panel of a general plasma display device. As shown in the drawing, the electrode array structure of the panel 20 of a typical plasma display device is sequentially arranged with X electrodes on one side of the rectangular panel 20 from X1 to Xn, and the X electrodes of the panel 20 are Y electrodes are sequentially arranged from Y1 to Yn on the other side of the formed side, and Z electrodes are sequentially arranged from Z1 to Zn on the side facing the surface on which the Y electrode of the panel 20 is formed. The panel of the plasma display device having the electrode array structure is then driven in connection with a predetermined driving module.

The coupling relationship between the panel of the plasma display device and the driving module for applying a predetermined driving signal to the panel is as follows.

3 is a view for explaining a method of coupling a panel and a driving module of a plasma display device. As shown in the drawing, in the method of coupling the panel and the driving module of the plasma display device, a frame 30 is attached to the panel 20, and predetermined supporter brackets 31 and 32 are attached to the frame 30. The driving module 33 is attached to the center portion of the upper portion of the frame 30.

The frame 30 supports the panel 20 and simultaneously dissipates heat generated when the panel 20 is driven.

The support brackets 31 and 32 are integrally formed with a predetermined groove (not shown) to enable the fastening with a housing (not shown) for protecting the panel 20 and mounting other components. In addition, a through hole through which a predetermined cable for electrical connection between the panel 20 and the driving module 33 passes is integrally formed.

The driving module 33 supplies a predetermined driving signal to the panel 20.

Looking at the coupling relationship between the panel and the drive module coupled through this process is as follows.

4 is a view for explaining a coupling relationship between a panel and a driving module of a plasma display device. As shown, the coupling relationship between the panel and the driving module of the plasma display device is attached to the frame 30 on one surface of the panel 20, the at least one driving module 33 in the center of the upper frame 30 At least one supporter bracket (31, 32) is attached to the periphery of the drive module (33). In addition, grooves for fastening with the housing and the like are formed in the upper portions of the supporter plackets 31 and 32, and through holes penetrating the supporter brackets 31 and 32 are formed in the side surfaces thereof.

At this time, the cable 41 for connecting each drive module 33 and the panel 20 passes through the supporter brackets 31 and 32 to electrically connect the drive module 33 and the panel 20 to each other. Accordingly, a predetermined drive signal output from each drive module 33 is applied to the panel 20 to drive the panel.

Here, look at the form that the cable for connecting the drive module and the panel passes through the supporter bracket as shown in Figure 5a to 5b.

5A to 5B are views for explaining a form in which a cable passes through the supporter bracket to connect the drive module and the panel. First, referring to FIG. 5, a cable penetrates the supporter bracket to connect the drive module and the panel to be formed through the supporter bracket 31 attached to the upper portion of the frame 30 attached to one surface of the panel 20. The cable 41 passes through the through hole 50. In this method of connecting the cable 41, after the cable 41 passes through the through hole 50, the cable 41 is tensioned by applying a force in both directions so that the current path becomes the shortest distance, and thus the cable 41 Predetermined portions A and B are fixed to the frame 30. At this time, the cable 41 is in close contact with the frame 30 and proceeds in the direction of the supporter bracket 31, but is not in close contact with the frame 30 from the predetermined point A and B to the through hole 50 of the supporter bracket 31. Proceed to float in the air.

In FIG. 5A, only the center portion of the supporter bracket 31 is not empty but is filled and described. However, the center portion of the supporter bracket 31 is considered when considering the convenience of the work and the manufacturing unit cost in manufacturing the supporter bracket 31. May be an empty state, that is, a state in which the center is cavitation (hereinafter referred to as a hollow state). For example, when the supporter bracket 31 is made using a predetermined object, for example, a metal rod, with a center portion filled, a predetermined drill such as a drill is formed to form a through hole, which is a passage through which a cable passes through a predetermined position of the metal rod. As a means, each of the metal rods should be drilled at a predetermined position. However, if the supporter bracket 31 is made of a predetermined metal plate, the supporter bracket 31 may be drilled at a predetermined position in the unfolded metal plate, and then only the folded metal plate may be folded. Thus, the supporter bracket 31 can be formed relatively easily using a relatively small amount of material. The case of using the hollow supporter bracket 31 is shown in FIG. 5B.

Referring to FIG. 5B, when the hollow supporter bracket 31 is used, the cable 41 has a hollow shape since the through hole 50 of the supporter bracket 31 is hollow. The through hole 50 of the supporter bracket 31 is not in close contact with the frame 30 and floats in the air, and the through hole 50 is not grounded and floats in the air.

When the cable 41 is floating in the air without being closely adhered to anywhere, the cable 41 is not grounded to the frame 30 and noise is generated in a signal passing through the cable 41. As a result, the driving of the panel 20 becomes unstable. In addition, there is a problem that the cable 41 is relatively easily broken by an external force because a tension of a predetermined size is generated at both ends of the cable 41.

In order to solve this problem, the present invention is to improve the connection structure of the cable that electrically connects the electrode of the panel and the drive module to reduce the noise of the cable, to prevent the damage of the cable by the external force of the plasma display device The purpose is to provide.

The present invention for achieving this object, the frame is attached to one surface of the panel, the supporter bracket attached to the upper portion of the frame, in order to dissipate heat generated when driving the panel, and attached to the upper portion of the frame A plasma display device including a driving module for applying a predetermined driving signal, wherein the supporter bracket has a through hole through which a cable passes, the panel and the driving module are electrically connected through a cable, and the cable is connected to the frame. And the panel and the driving module electrically connected to each other by passing through the through hole while being in close contact with the supporter bracket.                     

The cable may be a data cable for applying a data signal to the panel.

A cable support part is formed at a connection portion of the frame and the supporter bracket to increase the adhesion between the cable and the frame and the supporter bracket.

The through-hole is formed in the through-hole support is characterized in that to increase the adhesion with the cable passing through the through-hole.

The material of the through hole support and the cable support is characterized in that it is a predetermined conductive material.

Hereinafter, a plasma display device of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 6 is a diagram illustrating a form in which a cable passes through a supporter bracket in order to connect a driving module and a panel in the plasma display device of the present invention.

As shown in FIG. 6, in the plasma display device of the present invention, a cable passes through the supporter bracket to connect the drive module and the panel to include a top substrate and a bottom substrate, and have a predetermined gray scale according to a driving signal applied thereto. A supporter bracket 31 formed with a through hole 50, which is a passage through which the cable 60 passes, is attached to an upper portion of the frame 30 attached to one surface of the panel 20 that emits light, and the supporter bracket 31 is attached thereto. Cable 60 is installed in the form of penetrating through the through hole 50 of the). At this time, the cable 60 passes through the through hole 50 in close contact with the frame 30 or the supporter bracket 31.                     

The frame 30 supports the panel 20 and radiates heat generated when the panel 20 is driven.

The supporter bracket 31 is formed with a plurality of through holes 50 integrally to support the frame 30 to further improve the support force of the frame 30, and to fasten by fixing other components such as the housing.

The cable 60 electrically connects the panel 20 and a predetermined drive module (not shown). At this time, the driving module is a data driver, a scan driver or a sustain board. Since the panel 20 has a length in the horizontal direction in which the X electrodes are arranged longer than a length in the vertical direction in which the Y electrodes and the Z electrodes are arranged, the supporter bracket 31 is moved in the horizontal direction of the panel 20. It is more advantageous to install in terms of the stability of the panel 20. Therefore, the cable 60 is preferably a data cable that electrically connects the panel 20 and the data driver.

Here, when the cable 60 passes the supporter bracket 31 to electrically connect the panel 20 and the drive module, the cable 60 is in close contact with the upper part of the frame 30 toward the supporter bracket 31. In the connecting portion of the supporter bracket 31 and the frame 60 is bent at a predetermined angle. Then, the through hole 50 of the supporter bracket 31 proceeds to be in close contact with the supporter bracket 31, and at the starting point of the through hole 50, it is bent again at a predetermined angle to the inside of the through hole 50. The cable 60 passes through the supporter bracket 31. In this case, the adhesive material for closely contacting the cable 60 to the frame 60 or the supporter bracket 31 is preferably a conductive material.                     

In the plasma display device of the present invention having the cable connection structure as described above, the cable 60 electrically connecting the panel 20 and the driving module is installed in close contact with the frame 30 and the supporter bracket 31. The noise generated when the air is floating in the air is not generated. As a result, the driving of the panel 20 is stabilized. In addition, since the cable 60 is held in close contact with the frame 30 and the supporter bracket 31, the possibility of damage such as being broken by external force is significantly reduced. This increases the reliability of the panel 20.

In addition to the case of FIG. 6 described above, a form in which the cable is connected so that the cable is not sharply bent at the connection portion between the supporter bracket and the frame is as follows.

FIG. 7 is a view for explaining another form in which a cable passes through a supporter bracket to connect a driving module and a panel in the plasma display device of the present invention.

As shown in FIG. 7, another type of cable passing through the supporter bracket to connect the driving module and the panel in the plasma display device of the present invention is different from that of FIG. 6, in which the supporter bracket 31 is connected to the frame 30. A cable support 71 made of a predetermined conductive material is formed at a portion, that is, at a portion where the traveling path of the cable 70 changes rapidly.

The cable support 71 is formed by applying a predetermined conductive material, and is preferably the same material as that of the frame 30 or the supporter bracket 31.

Here, when the cable 70 passes the supporter bracket 31 to electrically connect the panel 20 and the driving module, the supporter bracket 31 is in a state in which the cable 70 is in close contact with the upper portion of the frame 30. While proceeding toward the support portion of the supporter bracket 31 and the frame 60 in a state in close contact with the cable support portion 71 is bent at a predetermined angle to proceed. Then, the through hole 50 of the supporter bracket 31 proceeds to be in close contact with the supporter bracket 31, and at the starting point of the through hole 50, it is bent again at a predetermined angle to the inside of the through hole 50. The cable 60 passes through the supporter bracket 31.

In this cable 70 connection structure, the noise generated when the cable 70 is floating in the air is not generated. As a result, the driving of the panel 20 is stabilized. In addition, the cable 70 is sharply bent at the connecting portion of the supporter bracket 31 and the frame 30 so that the cable 70 is damaged or the cable 70 at a part of the connecting portion of the supporter bracket 31 and the frame 30 is damaged. It is prevented from coming into close contact with the supporter bracket 31 or the frame 30. In addition, since the cable 70 is supported in close contact with the frame 30, the supporter bracket 31 and the cable support portion 71, the possibility of damage such as being broken by external force is significantly reduced. This increases the reliability of the panel 20. In addition, compared to the case of Figure 6 it is easier to close the cable 70 in the connection portion of the supporter bracket 31 and the frame 60.

6 to 7 described above, only the center portion of the supporter bracket 31 is not empty but is filled and described. However, the case in which the center portion of the supporter bracket 31 is empty, that is, in a hollow state will be described below. It is the same as FIG.

FIG. 8 is a view for explaining another form in which a cable passes through a supporter bracket to connect a driving module and a panel in the plasma display device of the present invention. As shown, the through hole support 80 is formed so that the cable 70 remains grounded even when the cable 70 passes through the empty center portion of the supporter bracket 31.

The through hole support 80 is formed by applying a predetermined conductive material, and is preferably the same material as that of the frame 30 or the supporter bracket 31. In addition, the through hole support 80 is formed to be electrically connected to the supporter bracket 31. Accordingly, the cable 70 does not float in the air when passing through the empty center portion of the supporter bracket 31, and is grounded through the through hole support 80.
