A fixing means 33 for fixing the plasma display device 31, a supporting means 34 provided on one side of the frame 32, and a plasma display device 31 coupled to the frame 32; And a case 35.

In more detail as follows.

As is well known, the plasma display device 31 is disposed so as to face the front panel 31a on which a sustain electrode and a bus electrode, a dielectric layer filling the electrodes, a protective layer are formed, and the front panel 31a. And an address electrode having a shape orthogonal to the sustain electrodes, a partition partitioning the discharge space, and a rear panel 31b having red, green, and blue phosphor layers applied to the partition wall.

The plasma display device 31 manufactures the front panel 31a and the back panel 31b, respectively, and then couples them by applying a sealing material along the edges, and exhausts the inside of the display device 31 by using an exhaust device. Then, a discharge gas of a mixed gas such as xenon (Xe) and neon (Ne) is injected, and then sealed and completed.

The frame 32 is coupled to the rear surface of the plasma display device 31. The frame 34 is provided with a circuit board (not shown) on which a plurality of electronic components are mounted so that an electrical signal can be transmitted to the plasma display device 31.

Fixing means 33 is interposed therebetween to couple the plasma display device 31 to the frame 32. The fixing means 33 is provided with a fixing portion 36 made of metal or synthetic resin, and a coupling portion 37 coupled to the fixing portion 36.

The fixing part 36 has a female screw 36a formed therein, and an adhesive member 38 made of a double-sided adhesive tape is attached to an end thereof so as to be fixed to the rear surface of the plasma display device 31. The coupling portion 37 is preferably a male screw threadable to the female screw 36a.

It is preferable that a plurality of fixing means 33 is provided at a portion of the backside of the plasma display device 31 where there is no connection terminal of the electrode. In addition, the fixing means 33 may employ other coupling methods such as bolts and nuts, rather than screw coupling methods.

The frame 32 is formed with a corresponding number of through holes 32a in order to couple the coupling portion 37 to the fixing portion 36, and a female screw may be formed when screwing. At least one or more of the upper and lower sides or the left and right sides of the frame 32 is provided with a support means 34, in one side may be formed in a single form, may be formed by separating a plurality. The support means 34 is made of metal or synthetic resin.

The support means 34 is integrally formed with a support part 34a coupled to an outer surface of the frame 32 and an extension part 34b extending from the support part 34a in the inward direction of the frame 32. .

In addition, the support part 34a is formed with a through hole 310 to be coupled to the coupling hole 32b formed in the frame 32 by a coupling means such as the male screw 300. The coupling hole 32b formed in the frame 32 is formed with a female screw so that the male screw 300 can be coupled thereto. At this time, the way that the support means 34 is coupled to the frame 32 may not only be a screwing method, but also other joining methods such as welding, riveting, fastening of the bolt and the nut.

The support part 34 extends a predetermined length from both ends of the support part 34a to a position where it does not interfere with the screen forming part of the plasma display device 31 on which the support means 34 is seated.

Meanwhile, a buffer member 39 may be further formed on the inner surface of the support means 34 in order to prevent the plasma display device 31 from being damaged due to shock or vibration when the plasma display device 31 is seated. . The buffer member 39 is preferably made of a material having excellent physical properties such as rubber or sponge, and may be formed in the entire region inside the support part 34a and the extension part 34b. It may be selectively formed only at a portion in contact with the plasma display device 31.

Meanwhile, the case 35 includes a front case 35a and a rear case 35b provided with a space part for accommodating the plasma display device 31 fixed to the frame 32. In this case, it may be said that the support means 34 may be installed at any one of the front case 35a and the rear case 35b to support the plasma display device 31.

Meanwhile, in order to couple the plasma display device 31 to the frame 32, the coupling part 37 is inserted through the through hole 32a of the frame 32 to be coupled to the fixing part 36. That is, the fixing part 36 has a female screw 36a formed therein, and the coupling part 37 made of a male screw is screwed together to enable mutual coupling.

At this time, in order to avoid interference between the plasma display device 31 and the support means 34 positioned on the upper side of the frame 32, the plasma display device 31 and the frame 32 are first combined. The support means 34 is fixed to the frame 32.

The long side portion (lengthwise direction) of the plasma display device 31 is in contact with the inner surface of the support means 34, or in contact with the upper surface when the buffer member 39 is formed.

Accordingly, the plasma display device 31 has the support part 34a or the buffer member of the support means 34 whose lower surface is installed on the frame 32 while being fixed to the frame 32 by the fixing means 33. 39, the adhesive member 38 can be stably supported even if the adhesive member 38 is separated from the display device 31 by external force or heat or magnetic weight generated during driving.

As a result, when the plasma display device 31 is fixed to the frame 32, a support means 34 that can be attached to or detached from the upper, lower, left, and right sides of the frame 32 is provided, or the front case 35a or the like. It is to provide this inside the rear case (35b).

Meanwhile, when the plasma display device 31 and the frame 32 are coupled to each other, a thermal conductive sheet may be interposed between the plasma display device 31 and the frame 32 so as to quickly discharge heat generated during the driving of the display device 31 to the outside. This thermally conductive sheet may also play the role of the above-mentioned adhesive member 38 in some cases.

FIG. 5 illustrates the plasma display device 31 and the frame 52 separately from the plasma display device assembly according to the second embodiment of the present invention.

Here, the same reference numerals as in the above-described drawings indicate the same members having the same function.

Referring to the drawings, the plasma display device 31 includes a plurality of electrodes, a dielectric layer, a phosphor layer, a front panel 31a and a rear panel 31b having partition walls formed thereon to form an image.

The plasma display device 31 is coupled with a frame 52 for fixing it. Fixing means 33 is interposed to couple the plasma display device 31 to the frame 52. The fixing means 33 is coupled to the fixing part 36 through a fixing part 36 fixed to the rear surface of the plasma display device 31 and a through hole 52a formed in the frame 52. The part 37 is provided.

An adhesive member 38 made of a double-sided adhesive tape is attached to the fixing portion 36 so that the plasma display device 31 is fixed to the end portion thereof, and a female screw 36a is formed therein. The female screw 36a is screwed with a coupling part 37 such as a male screw.

Here, the support means 54 is provided on one side of the frame 52. The support means 54 may be formed in a single type, or may be formed in a plurality of spaced apart a predetermined interval.

The support means 54 includes a support portion 54a having a predetermined width and an extension portion 54b extending inwardly of the frame 52 from the support portion 54a. The support part 54a extends integrally from one side of the frame 52 in the direction in which the plasma display device 31 is installed, and is formed to have a width at which the display device 31 can be seated. As such, since the support means 54 is formed integrally with the frame 52, it is not necessary to fix the frame 52 to the frame 52 using a separate coupling means.

On the other hand, the inner surface of the support portion 54a may be further provided with a buffer member 39, such as a rubber material, which can absorb shocks in order to prevent the plasma display device 31 from being damaged by external force or its own weight upon mounting. There will be.

FIG. 6 shows a supporting means 64 according to a third embodiment of the present invention, and FIG. 7 shows that the plasma display device 31 and the frame 72 are coupled using the supporting means 64 of FIG. 6. The state is shown.

Here, the same reference numerals as in the above-described drawings indicate the same members having the same function.

6 and 7, the support means 64 includes a flat plate portion 64a and a jaw portion 64b extending from both ends of the flat plate portion 64a. The jaw portion 64b protrudes upwardly from the flat plate portion 64a, and a part of the bottom surface 64c is formed to be elastically in contact with the rear surface of the frame 72 so as to be supported. To this end, the support means 64 is made of a metal material or synthetic resin having an elastic force.

The frame 72 coupled to the rear surface of the plasma display device 31 including the front panel 31a and the rear panel 32a has a corresponding number of through holes 72a for allowing the plurality of support means 64 to pass therethrough. ) Is formed.

The support means 64 is attached to the lower surface of the flat plate portion 64a by the adhesive member 38 so that the flat plate portion 64a is interposed therebetween and the plasma display device 31 is attached thereto through the through hole 72a. It is. The jaw portion 64b is positioned along the edge of the through hole 72a, and a part of the bottom surface 64c elastically contacts the rear surface of the frame 72 so that the jaw portion 64b is positioned with respect to the frame 72. The plasma display device 31 is fixed.

A plurality of fixing means 64 are provided to firmly and support the plasma display device 31 over the rear surface of the frame 72. In addition, a cover member 71 is installed on the upper portion of the jaw portion 64b to more firmly support the protection means 64 and to protect the support means 64. The cover member 71 completely surrounds the jaw portion 64b, and in some cases, the cover member 71 is coupled to the flat plate portion 64 and the frame 72 by coupling means to improve the bearing force.

As such, in the present embodiment, unlike the case of other embodiments, no additional fixing means, such as screwing or the like, is required to fix the plasma display device 31 to the frame 72. In addition, in order to detach the plasma display device 31 from the frame 72, when the jaw portion 64b is applied with a predetermined pressing force in a direction facing each other on both sides, the bottom surface 64c is exposed to the frame. It will be said that the back of 72 can be separated or supported. This is because the end of the jaw portion 64b elastically supports the frame 72.

FIG. 8 illustrates a separate state in which the plasma display device 31 and the frame 32 are coupled to each other in the plasma display device assembly according to the fourth embodiment of the present invention.

Here, the same reference numerals as in the above-described drawings refer to the same member having the same function, and only the features of the present embodiment will be described by explaining.

Referring to the drawings, the plasma display assembly includes a plasma display device 31 including a front panel 31a and a rear panel 31b, a frame 32 coupled to the plasma display device 31, and the frame ( It includes a support means 34 installed on at least one side of the 32.

The support means 34 is detachably coupled to the frame 32 as described above, and has a support portion 34a having a width at which the plasma display device 31 and the frame 32 are seated, and extending therefrom. It consists of an extension portion 34b. The support part 34a has a through hole 310 formed therein so as to be coupled to the frame 32, and the male screw 300 coupled to the coupling hole 32b formed in the frame 32 through the through hole 310. ) Are combined. In addition, a buffer member 39 may be formed inside the support part 34a. On the other hand, the support means may be molded in such a way as to extend integrally from the frame 32 instead of the detachable support means 34.

Here, at least one adhesive member 81 is attached to the plasma display device 31. The adhesive member 81 is attached to the rear surface of the rear panel 31b at a predetermined interval along one of the upper and lower surfaces.

The plasma display device 31 is attached to the front surface of the frame 32 via the adhesive member 81. Since the adhesive member 81 is locally attached to only one point, the frame 32 is attached. From this, it can be said that the plasma display device 31 is easily separated.

In this case, as shown in FIG. 9, a plurality of adhesive members may be attached to upper and lower surfaces of the rear surface of the plasma display device 31 in order to reduce the adhesive force.

At least one or more first adhesive members 81 may be attached to the upper surface of the plasma display device 31 at predetermined intervals, and at least one or more second adhesive members 91 may be attached to the lower surface thereof. In this case, the adhesion coefficients of the first adhesive member 81 and the second adhesive member 91 are different from each other.

That is, when the adhesion coefficient of the first adhesive member 81 is high, the second adhesive member 91 has a value lower than that of the first adhesive member 91. In addition, the adhesion coefficients of the first and second adhesive members 81 and 91 may be reversed.

Substantially, the Applicant said that the first adhesive member 81 uses an adhesive having a low adhesive coefficient, such as a brand name VHB No. 4920 tape produced by 3M, USA, and the second adhesive member 91 has an adhesive coefficient. High adhesives such as the trade name VHB No. The experiment was performed by applying a 4945 tape.

Examining the result, the adhesive force of the first adhesive member 81 is 90 N / cm, whereas the adhesive force of the second adhesive member 91 is 44 N / cm. The adhesive member 91 has about 1.7 times better adhesive strength than the first adhesive member 81.

When the adhesive members 81 and 91 having such different adhesion coefficients are respectively attached to the upper and lower parts of the back surface of the plasma display device 31, the first adhesive member 81, which has relatively weak adhesive force, is physically prioritized. After detaching, the display device 31 can be easily separated from the frame 32 by separating the second adhesive member 91 side. In addition, since the supporting means (see FIG. 8) is provided along the sides of the frame 32, it is possible to stably support the plasma display device 31.

As described above, the plasma display device assembly according to the present invention may have the following effects by supporting means for supporting the plasma display device with respect to the frame or the case.

First, even if the plasma display device is dropped from the frame by external force or its own weight, the plasma display device is supported by the support means supported on the upper, lower, left and right sides of the frame, thereby preventing damage.

Second, in the event that an abnormality occurs in the plasma display device to be disposed of, it can be easily separated from the frame, and the frame can be recycled, thereby reducing manufacturing costs.

Third, the method of combining the plasma display device with respect to the frame is simplified, thereby increasing production efficiency.

Although the present invention has been described with reference to one embodiment shown in the drawings, this is merely exemplary, and it will be understood by those skilled in the art that various modifications and equivalent other embodiments are possible. Therefore, the true technical protection scope of the present invention will be defined by the technical spirit of the appended claims.
