A cross section taken along the line. Referring to FIG. 2, the plasma display module includes a chassis base 150 and a plasma display panel 130 that is supported in front of the chassis base 150 and implements an image, and is supported behind the chassis base 150. And a circuit unit (not shown) for driving the plasma display panel 130. In addition, a heat dissipation sheet 140 and a double-sided tape 145 surrounding an outer edge of the heat dissipation sheet 140 are interposed between the plasma display panel 130 and the chassis base 150.

The plasma display panel 130 is an image display unit that implements an image by using a discharge phenomenon, and includes a front panel 110 and a rear panel 120 that are coupled to face each other. Since a large amount of heat is generated in the plasma display panel 130 where discharge is performed, the heat generated by attaching the heat dissipation sheet 140 on the rear surface of the plasma display panel 130 is rapidly spread through the heat dissipation sheet 140. To this end, the heat dissipation sheet 40 may be formed of, for example, high oriented graphite or the like having excellent thermal conductivity. Although not shown in the drawing, a circuit part for supplying driving signals and power to the plasma display panel 130 is mounted to the rear of the chassis base 150. The circuit part includes various circuit elements and a circuit on which the circuit elements are mounted. It consists of a board | substrate, various wirings, etc.

As can be seen in the figure, the chassis base 150 is formed in a rectangle having a pair of long side portions 150a and a pair of short side portions 150b. Since the chassis base 150 functions as a supporting structure of the plasma display panel 130 made of glass, the rigidity of the chassis base 150 along each of the long side portion 150a and the short side portion 150b is achieved. It is preferable that the bent portion 151 is formed to contribute to. In addition, the reinforcing member 155 along the long side portion 150a direction is formed in each of the upper side and the lower side of the chassis base 150 in symmetrical direction. Another reinforcing member along the short side portion 150b may be mounted between the upper and lower reinforcing members 160. Meanwhile, since the chassis base 150 functions as a heat sink of the plasma display panel 130 supported at the front or the circuit part supported at the rear, the chassis base 150 is formed of a material having excellent thermal conductivity, for example, aluminum (Al). It is preferable.

3 and 4, the reinforcing member 155 in the long side portion 150a direction is a flange portion 155a fixed to the rear surface of the chassis base 150, protrudes rearward, and is substantially parallel to the chassis base 150. And a connection part 155b connecting the flange part 155a and the base part 155c. The flange portion 155a is screwed to the chassis base 150 by a fastening member 153 passing therethrough. Guide bases 155 'are formed in the base portion 155c in the longitudinal direction thereof, and the guide slots 155' are symmetrically formed inward from one end and the other end of the base portion 155c, respectively. The handle member 160 is inserted while sliding along the guide slot 155 ′.

Referring to FIG. 2, the handle member 160 is slidably coupled to the upper and lower reinforcement members 155, respectively, so as to be symmetrically paired at both ends of the reinforcement member 155. As shown in FIGS. 3 and 4, the handle member 160 protrudes rearward and is bent toward the chassis base 150 from the grip part 160b and the grip part 160b where the operator's hand is gripped so as to reinforce the member 155. It includes a support portion (160a) for supporting the grip portion (160b) in contact with the inner surface. The grip portion 160b is formed with a grip hole 160 ′ penetrated to allow a worker to grip.

As described above, in the plasma display module of the present invention including the present embodiment, the grip member as the gripping means is fixed by the sliding coupling method. In the prior art as shown in FIG. 1, since the handle member 60 is fixed by the screw 70 fastened to the boss 55, a plurality of bosses 55 and screws 70 are required to manufacture the display device. The unit cost rises, and in particular, the product yield is reduced due to the time required for screw fastening operation. However, in the present invention, the coupling of the handle member is made by the sliding method, thereby making it possible to structurally solve the above-mentioned problems, and also to prevent the phenomenon of detachment of the handle member due to the conventional screwing failure. There is this.

FIG. 5 is a modified example of the plasma display module shown in FIG. 3, and an excerpt perspective view of a part of the plasma display module according to the second embodiment of the present invention is shown, and FIG. 6 is a line VI-VI of FIG. 5. A cross section taken along is shown.

As can be seen in the drawings, also in this embodiment, the rear of the chassis base 250, for example, the back is provided with a reinforcing member 255 along the long side portion 250a direction, the reinforcing member 255 is a chassis A flange portion 255a coupled to the base 250, a base portion 255c protruding backward to be parallel to the chassis base 250, and a connecting portion 255b interconnecting the flange portion 255a and the base portion 255c. It is made, including. The base portion 255c is formed in pairs with guide slots 255 'extending inwardly from both ends thereof in a longitudinal direction, and a handle member 260 is inserted into and fixed to the guide slot 255'. The handle member 260 includes a support part 260a facing the inner surface of the reinforcing member 255 and a grip part 260b protruding backward from the support part 260a and held by an operator. The handle member 260 of the present embodiment has an open structure with one end open. The handle member 260 of such a structure may be formed by cutting the flat plate member to a predetermined size and then bending and bending the flat member. In this case, a sharp edge surface 260aa (refer to FIG. 6) may be formed at the open end of the handle member 260 having the cut surface, and may damage the opposite surface of the chassis base 250 during the sliding coupling process. Therefore, in the plasma display module of the present embodiment, a separate protective plate 265 is interposed between the open end of the handle member 260 and the opposing chassis base 250. That is, the protective plate member 265 is coupled to the inside while being guided by the reinforcing member 255, and then the handle member 260 is slidably coupled along the guide slot 255 ′. At this time, the handle member 260 is coupled while sliding on the pre-mounted protective plate 265, bar damage to the chassis base 250 in the bonding process is to be prevented. Reference numeral 260 ′, which is not described in the drawing, denotes a gripping hole in which a worker's hand is gripped, reference numeral 251 denotes a bent portion bent along the long side portion 250a and the short side portion 250b, and reference numeral 253 A fastening means for fastening the chassis base 250 and the reinforcing member 255 is shown.

Meanwhile, although the protective plate member 265 is illustrated as a separate structure separately formed from the handle member 260 in FIGS. 5 and 6, the protective plate member 265 may be integrally formed with the handle member 260. In this case, the handle member is formed in a closed structure. As a result, the inconvenience of having to couple the protective plate and the handle member can be eliminated, thereby further improving the workability.

Meanwhile, in the drawings attached to the present specification, the reinforcing member and the handle member slidingly coupled thereto are illustrated as having a cross-sectional structure of an approximately uneven shape, but the cross-sectional shape is merely exemplary, and the cross section of the reinforcing member or the handle member The shape need not be particularly limited as long as it has a shape corresponding to each other so as to be slidable.

According to the plasma display module of the present invention, the following effects can be achieved.

First, according to the present invention, since the handle member as a gripping means is coupled to the reinforcing member during the transport operation, there is no need for a separate mounting hole for mounting. That is, according to the prior art, four bosses and screws per handle member are required, which is a burden on the manufacturing cost, and in particular, four screw fastening operations are required, which causes a decrease in the yield of the product. In the present invention, since no separate manual fastening or manual work for fastening is required, the productivity of the product can be improved.

Secondly, according to the present invention, since the handle member is slidingly coupled, the detachment of the handle member generated when the screw is in a poor state, as in the prior art, is prevented, whereby the workability during the transport of the plasma display module is prevented. Is improved.
