BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plasma display device, and more particularly, to a plasma display device having an attachment cloth which enables the plasma display panel to be firmly attached to the chassis base and which allows the plasma display panel to be easily separated from the chassis base. It is about.

Plasma display panels, which are recently attracting attention as replacing conventional cathode ray tube display devices, have a discharge voltage applied after a discharge gas is filled between two substrates on which a plurality of electrodes are formed. As a result, the phosphor formed in a predetermined pattern is excited by ultraviolet rays generated from the discharge gas, thereby obtaining a desired image. The display capacity, brightness, contrast, afterimage, and viewing angle are excellent in various display capacities. Has the advantage. The plasma display panel is coupled to a chassis base disposed to be substantially parallel to the plasma display panel at a rear side thereof, and to a driving circuit unit disposed at a rear surface of the chassis base and connected to electrodes of the plasma display panel. Achieves a plasma display device.

A conventional plasma display device is schematically shown in FIG. Along with the edge of the plasma display panel 110, a COF or TCP (chip on film, tape carrier package, 111) and a flexible printed circuit (FPC) 112 are formed, and the plasma display panel 110 of the chassis base 130 is formed. In order to compensate for the rigidity of the chassis base 130 formed in a thin plate on the opposite side, that is, the rear side of the chassis base 130, the horizontal reinforcement members 132 and 133 and the vertical reinforcement member 131 are disposed. The plasma display panel 110 is typically attached to the chassis base 130 by a double-sided adhesive tape 121 as shown in FIG. 1.

However, after the plasma display panel 110 is fixed to the chassis base 130 by the double-sided adhesive tape 121, the plasma display panel 110 is changed to the chassis base 130 by the adhesive force of the double-sided adhesive tape 121. It is not easily separated from. As a result, when the plasma display panel is separated from the chassis base, an excessive force may be applied to deform or damage the plasma display panel or the chassis base. This deformation or damage causes a problem in that it is difficult to separate and rearrange or recycle the plasma display panel and the chassis base. In addition, since the plasma display panel made of glass and the chassis base made of a metal material have different thermal expansion rates, the plasma display panel and the chassis base are caused by the heat generated from the plasma display panel when the plasma display device is operated. Thermal expansion causes a problem that the plasma display panel may be separated from the chassis base due to different thermal expansion between adjacent surfaces of both components, and the attachment of the low thermal conductive double-sided tape to the portion of the plasma display panel to which the double-sided tape is attached. Due to this, there is a disadvantage that the internal heat that can be generated during operation is not effectively released to the chassis base.

On the other hand, the plasma display device disclosed in Japanese Patent Application Laid-Open No. 1998-319863 has a structure for attaching the plasma display panel to the chassis base by using a fixing bolt and a boss corresponding to the fixing bolt, and a pin and plate having a flange. A structure for attaching a plasma display panel and a chassis base using a spring is also disclosed. However, in the case of the plasma display device according to the prior art, not only is the work process complicated in constructing and mounting the fixing bolt and the boss, but also causes a problem that the process cost and manufacturing cost increase as the number of components increases. Since the plasma display panel and the chassis base are fastened and held only by the fixing force of the thin plate spring, the plate spring provides sufficient support force during operation or when an external impact is applied. There is a problem in that it cannot be formed to maintain the mounting coupling between the plasma display panel and the chassis base.

The number of elements and the fabrication process can be greatly reduced to significantly reduce manufacturing costs, and sufficient support between the plasma display panel and the chassis base can be secured. In addition, by almost removing the double-sided tape that has been conventionally used when the chassis base and the plasma display panel are mounted, the heat generated from the plasma display panel can be smoothly transferred to the chassis base to achieve smoother heat dissipation of the plasma display panel. .

The plasma display device according to the present invention may take various structures for coupling the holder and the holder receiving member in a direction parallel to or perpendicular to the plasma display panel.

In the case of the plasma display device having a holder and a holder accommodating member coupled in a direction parallel to the plasma display panel according to the present invention, a holder having an appropriate rigidity is placed in the longitudinal direction in parallel with the long side of the plasma display panel. By extending the panel as a whole, it is possible to supplement or replace the reinforcement that was conventionally provided in the chassis base.

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 protection scope of the present invention will be limited by the technical spirit of the appended claims.
