Problems solved by technology

[0010] However, the above-mentioned liner 8 is obtained by smearing a conductive substance on the periphery of a tinfoil-shaped rod, so the bonding ability with the above-mentioned bracket 6 or the front cover 7 is not strong, so the grounding ability may be reduced. It is fixed by a substance similar to double-sided tape with an adhesive component, so its fixing ability is also weak
[0011] As mentioned above, since the grounding ability and fixing force of the filter are weakened, the electromagnetic waves leaking outside without shielding will increase, so there is a problem that it may have adverse effects on the human body of consumers of audio-visual plasma display devices

Abstract

The disclosed plasma display device comprises: a substrate, a filter in front of the substrate to shield electromagnetic wave, a heat dispersion plate fixed on front of the substrate, and a grounding clamp to fasten all former members and fix two of the filter and the plate on edge of the substrate. This invention applies grounding clamp to fix the filter and heat dispersion plate, reduces the effusive electromagnetic wave, increases the cutting rate for electromagnetic wave, and easy fixes the filter, the substrate, and the heat dispersion plate.

Description

1. Technical field [0001] The invention relates to a plasma display device, in particular to a plasma display device which improves an electromagnetic wave shielding filter and improves grounding and fixing capabilities by using a grounding clip. 2. Background technology [0002] Recently, various flat panel display devices have been developed that reduce the disadvantages of cathode ray tubes (Cathode Ray Tube), that is, weight and volume. ), plasma display panels (Plasma DisplayPanel: PDP) and electroluminescent (Electro-Luminescence: EL) displays, etc. [0003] Among them, PDP is a flat-panel display device that uses plasma discharge to display images. It has a high response speed and is suitable for displaying large-area images, so it is used in high-resolution TVs, monitors, and indoor / outdoor advertising displays. [0004] 1 is a partial oblique sectional view showing a conventional plasma display device, and FIG. 2 is a sectional view showing a thin film filter groun...
