Problems solved by technology

However, even though the chassis supported by synthetic resin solves the problems related to its strength and the heat dissipation performance of the plasma display device, since the synthetic resin does not conduct electricity, an electrical grounding problem arises, and thus cannot be used to make circuit components mounted thereon grounding

Embodiment Construction

[0015] Referring now to the drawings, FIG. 1 is a schematic exploded perspective view of a plasma display device according to an embodiment of the present invention. Referring to FIG. 1 , a plasma display apparatus 100 includes a panel 103 , an adhesive member 108 , a base 109 , a circuit part 110 , a protection plate 120 , a connection member 130 , a thin metal plate 140 and a direct-attachment filter 160 .

[0016] The panel 103 displays an image by performing discharge from operation signals transmitted in accordance with circuit elements provided on the circuit part 110 . The panel 103 has barrier ribs, electrodes, fluorescent materials, dielectric materials, and protective layers formed between the two substrates 103a and 103b. In addition, the panel 103 has discharge cells defined by the substrates 103a and 103b and barrier ribs. A discharge is generated in the discharge cell. These discharge cells are filled with an inert gas that generates ultraviolet rays. The iner...

Abstract

A plasma display apparatus. The plasma display apparatus uses a synthetic resin chassis base. A thin metal plate is attached between the panel and the chassis base and is connected to grounded terminals of the circuit portion and to an electromagnetic wave blocking direct-attachment filter on a front of the panel. Such a structure is advantageous in that as the synthetic chassis base is employed in the plasma display apparatus, it is possible to reduce the amount of material used and to reduce molding costs, to simplify processes, and to decrease the weight and noise of a module. Second, the plasma display apparatus has another advantage of securing a ground for the circuit portion and improving the stability of the plasma display panel module, as the thin metal plate can be electrically connected to the direct-attachment filter and perform the grounding function.

Description

technical field [0001] The present invention relates to a plasma display device, and more particularly to a plasma display device having a base made of a synthetic resin instead of a metal such as aluminum, so that while improving workability, the overall weight is reduced, and the number of parts used is reduced. The number of components is reduced, the noise is reduced, and the production cost is reduced. A thin metal plate can also be used as a thin grounding plate to improve the electrical connection and grounding performance of the conductive circuit part and the panel. Background technique [0002] Recently, various flat panel display devices have been developed instead of cathode ray tubes. Representative examples of such flat panel display devices include liquid crystal display devices, electroluminescence display devices, electroluminescence display devices, and plasma display devices. Plasma display devices can display images through plasma discharge, and have th...
