Embodiment Construction

[0017] A kind of embodiment of the present invention is described below with reference to accompanying drawing:

[0018] Referring to Fig. 3, following several parts are represented among the figure: the PDP20 that produces hot air; Be positioned at the back cover 21 of PDP back side; The shape is changed to form a recessed installation groove 22; a porous sound-absorbing pad placed in the installation groove, etc.

[0019] The structural features are explained in detail below: Considering that the hot gas generated inside the PDP 20 moves upwards, the ventilation hole is opened above the rear cover 21 .

[0020] The above-mentioned installation groove 22 is disposed around the air hole 23 . The mounting grooves are of the same shape, and they can be arranged in a staggered or continuous manner around the air hole 23 . In order to make the sound-absorbing pad 24 be placed in all the installation grooves 22, the installation grooves 22 are made into a uniform shape and size. ...

Abstract

The structure comprises following parts: there are vent holes for discharging hot sir on back cover of the panel display. Cooling fan is setup on side of the vent holes at inner side of main body. Mounting groove is arranged around periphery of back cover with vent holes. Noise absorption pad is put inside the mounting groove. The structure makes display cooling effectively and cuts off noise effectively.

Description

technical field [0001] The invention relates to flat panel display technology, in particular to a flat panel display noise prevention device capable of reducing noise generated in the flat panel display to the greatest extent. Background technique [0002] Plasma displays (or PDPs) are thin, large screens that can present good-quality images. Due to these advantages, its application range is rapidly expanding, especially in public places. On the other hand, it has become a trend that plasma displays have begun to enter households recently due to lower prices. [0003] However, PDP picture reproduction is realized based on the principle of plasma generation, and the generation of plasma is inevitably accompanied by the generation of a large amount of heat, so it is an important issue to quickly dissipate heat outward. [0004] FIG. 1 illustrates the heat dissipation structure of a conventional PDP. Referring to FIG. 1 , the heat dissipation structure of a conventional PDP ...
