The present invention relates to a plasma display device, and more particularly, to a plasma display device that enables simple and robust fixing without requiring a separate fastener such as a screw when mounting a filter.

In general, as shown in FIGS. 1 and 2, the plasma display apparatus includes a front case 1 in which a window is formed, a rear case 2 forming an inner space together with the front case 1, and A chassis (5) on which a plasma display panel (3) disposed in an interior space, a substrate (4) coupled to the plasma display panel (3), and a circuit for driving the plasma display panel (3) are wired are arranged; It is the structure comprised by the filter 6 located in front of the said plasma display panel 3. As shown in FIG.

Here, the filter 6 is installed by the filter holder 7 to be spaced apart from the plasma display panel 3 at a predetermined distance S, and a separate glass plate for maintaining flatness therein ( Not shown).

That is, the reason why the filter 6 is provided to be spaced apart from the plasma display panel 3 at a predetermined distance S is to discharge heat generated in the plasma display panel 3. For this reason, filters, such as a UV filter, a mesh filter, a near-infrared filter, and a protective filter formed from a thin film, were attached to the separate glass plate which can fix them flat.

However, in the conventional plasma display device, the installation of the filter 6 spaced apart from the plasma display panel 3 is cumbersome, and the weight of the product is greatly increased due to the separate glass plate, as well as the separate glass plate and the plasma display. There is a problem in that the cost increases due to ancillary parts such as the filter holder 7 spaced apart from the panel 3.

On the other hand, in order to solve the problems of the conventional plasma display apparatus, there have been attempts to attach the filter directly to the plasma display panel 3, but electrical grounding of the filter 6 is difficult, and the filter 6 is a panel. Because of covering (3), there was a problem such as poor heat radiation performance.

In addition, the method of attaching the filter 6 to the panel 3 and fixing it to the chassis is inevitably dependent on a separate fastener such as a screw, thereby increasing production time, work force, and production cost due to cumbersome fastening of a plurality of fasteners. There was a problem such as being.

An object of the present invention for solving the above problems, by using the locking portion and the hook portion to be bonded to each other to enable fast and accurate fastening of the filter to the chassis without a separate fastener production time and work force and production The present invention provides a plasma display device that can significantly reduce cost and to form a support that supports a hook portion in the front case to thereby strengthen the bonding strength, thereby enabling a more secure fastening.

Plasma display device of the present invention for achieving the above object, the front case is formed window; A rear case forming an inner space together with the front case; A plasma display panel disposed in the internal space; A chassis coupled to the plasma display panel and having a substrate wired with a circuit for driving the plasma display panel; A filter installed in front of the plasma display panel; And one end portion is connected to the filter to fix the filter, and is electrically grounded to the filter for shielding electromagnetic waves, and the other end portion is hooked to the chassis so that the other end is caught by a hook portion formed in the chassis. It characterized in that it comprises a; a ground body formed with a corresponding hook portion.

In addition, the hook portion is the end portion is bent in the shape of "c", the locking portion is a locking groove formed in the chassis reinforcement portion of the position corresponding to the bent end of the hook portion, or the hook portion is an end portion It is a shape bent to "c", it is possible that the locking portion is a locking blade formed on the chassis reinforcement portion of the position corresponding to the bent end of the hook portion.

In addition, it is preferable to form a support on the front case such as a rubber (rubber) for pressing the locking portion toward the locking portion in order to prevent the locking portion of the ground body from being separated from the locking portion of the chassis. .

On the other hand, it is preferable that the filter is a direct attachment filter attached directly to the plasma display panel.

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

First, as shown in FIG. 3, the plasma display apparatus according to an exemplary embodiment of the present invention includes a front case 1 having a window formed therein and a rear case forming an inner space together with the front case 1. (2), a chassis in which a plasma display panel 3 disposed in the inner space and a substrate coupled with the plasma display panel 3 and having a circuit for driving the plasma display panel 3 are wired are arranged. 5) and a filter 60 provided in front of the plasma display panel 3 and a grounding body 100 provided between the filter 60 and the chassis, and in particular, the grounding body 100. ), One end is connected to the filter 60 to fix the filter 60, electrically grounded with the filter 60 for shielding electromagnetic waves, the other end is formed in the chassis 5 To 110 The hook portion 120 corresponding to the hook portion 110 of the chassis 5 is formed at the other end to be hooked.

In this case, the filter 60 is preferably a direct filter 60 directly attached to the plasma display panel 3.

In addition, the hook portion 110 and the hook portion 120 may be formed in a variety of shapes, Figure 3 is an example, the hook portion 120 is the end is bent to "c" The hook portion 110 has a locking groove 111 formed in the chassis reinforcement 51 at a position corresponding to the bent end of the hook ring portion 120.

Accordingly, the operator may fix the ground body 100 to the chassis 5 so that the filter 60 may be firmly fixed to the plasma display panel 3 when the operator assembles the ground body 100. By hooking the bent end of the hook ring portion 120 into the hook groove 11 formed on the reinforcing portion 51 of the reinforcement portion (5), the hook ring portion 120 is inserted into the hook groove 111 and caught. It is possible to be firmly fixed without a separate fastener such as a screw.

Therefore, it is possible to greatly reduce the production time, labor and production costs by simplifying the fastening work.

On the other hand, the shape of the hook portion 110 and the hook portion 120 may be very diverse, in addition, as shown in Figure 4, the hook portion 120 is bent to the end "C" It is also possible that the hook portion 110 is a locking blade 112 formed on the chassis 5 reinforcement portion 51 of the position corresponding to the bent end of the hook ring 120. .

On the other hand, as shown in Figure 3 and 4, when assembling the front case 1 in order to further secure the fastening of the hook portion 110 and the hook portion 120, the ground body 100 Rubber to press the catch ring portion 120 toward the catch portion 110 to prevent the catch ring portion 120 from being separated from the catch portion 110 of the chassis 5. It is preferable to form the support body 130 is made of the elastic material of the front case (1).

Here, the support 130 may be manufactured in a wide variety of shapes that can press the locking ring 120 in the direction of the hook portion (110).

The present invention is not limited to the above-described embodiments, and of course, modifications may be made by those skilled in the art without departing from the spirit of the present invention.

Therefore, the scope of the claims in the present invention will not be defined within the scope of the detailed description, but will be defined by the following claims and the technical spirit thereof.

As described above, according to the plasma display device of the present invention, the filter can be fastened accurately and quickly without a separate fastener, thereby greatly reducing production time, work force, and production cost, and jamming the front case. By forming a support to support the ring portion to reinforce the bonding strength is to have a more robust fastening effect.
