Description
Technical field
The present invention relates to a kind of anti-electromagnetic wave structure module of plasma display, particularly a kind ofly on second holder of fixing filter, set up metal the 3rd holder, and the outer rim that is engaged in back casing is provided with L type flanging, to prevent the anti-electromagnetic wave structure module of plasma display of electromagnetic-wave leakage.
Background technology
Along with the quick progress and development of science and technology, the product arround various new sciences and technologies constantly are developed out and progressively are applied to live makes the common people can enjoy the convenience that science and technology is brought.With TV, from traditional iconoscope TV, projection TV to the plasma display (PDP) and the LCD (LCD) that rise to recently to main product.Though wherein plasma display is different with the principle of LCD, it is frivolous to have volume equally, the advantage that does not take up space, the primary selection when therefore having become most common people and changing planes.And plasma display is a kind of flat-panel screens luminous by gas discharge, and it mainly is that two parallel substrates are set in plasma display, is provided with electrode in substrate, is filled with ionized gas simultaneously between substrate.And its principle of luminosity is to utilize electrode discharge to produce plasma and ultraviolet light, utilizes the UV-irradiation that produced on fluorophor and send macroscopic color of light.Therefore inevitably, aforementioned plasma display utilizes the display mode of electrion, can produce many electromagnetic waves, though and electromagnetic wave is very many for the research report of health effects at present, also the definite research evidence of neither one can prove that it is to health affected, but various countries all pay much attention to for the electromagnetic problem of electric equipment products, and it are included in the standard of check.
And the manufacturing of plasma display at present can be divided into the two large divisions with sale is actual, one is the manufacturer that is responsible for producing Plasmia indicating panel, another then is the sale manufacturer that is responsible for last shell assembling and hangs up Own Brand, and whether a plasma display anti electromagnetic wave effect is good, the design of framework whole with it (comprising housing) has very important relation, and all know for the personnel that are familiar with electromagnetic characteristics, metal material has the special efficacy of counterchecking electromagnetic wave, therefore will effectively intercept electromagnetic wave leaks, the shell that the simplest and effective way just is to use metal material to make is coated on whole plasma display assembly in it.But in fact, if people are careful a little for the shell of the plasma display that is sold on the market, necessarily can find wherein to have only the machine of few part to use metal shell fully, especially procapsid, most manufacturer still adopts plastic casing, its chief reason is exactly to be conceived to considering of appearance design and cost, because though the shell made from metal material has the preferable function that electromagnetic wave leaks that blocks, but this relative metal shell but has the material cost height, processing is difficult for and the outward appearance shape design is limited and mould takes high disappearance, makes manufacturing cost increase.
See also the generalized section of commonly using plasma display at present shown in Figure 1, this plasma display mainly is made up of a procapsid A, a filter B, one first holder C, a plasma display floater D, one second holder E and a back casing F.Wherein, the first holder C, the second holder E and back casing F are made by metal material, this first holder C can be fixed thereon for Plasmia indicating panel D, and the end of the second holder E can link fixing with back casing F, the other end then can cooperate the both sides that are individually fixed in filter B with procapsid A, reach the effect that filter B is gripped, filter B is positioned at an inner side and is coated with layer of conductive film G again, uses and reduces the on-stream electromagenetic wave radiation that produces.
And in above-mentioned commonly using in the structure, the second holder E is provided with " L " type flanging with the end that back casing F links and can contacts with flat back casing F outer rim, and utilize screw both to be screwed togather locking in the mode of interval one suitable distance, because the second holder E all is that large tracts of land contacts with back casing F, therefore inevitably can produce many gaps at both contact-making surfaces, go out by this clearance leakage in order to prevent the electromagnetic wave that Plasmia indicating panel D is produced, therefore commonly use structure and between the two contact-making surface of the second holder E and back casing F, be provided with conducting foam H, but by being provided with of conducting foam H fill up between the second holder E and back casing F the subject of knowledge and the object of knowledge produce between the crack, reach the possibility that certain obstruct electromagnetic wave leaks, in addition, same reason, though coating is provided with layer of conductive film G on filter B in order to prevent electromagnetic wave from being leaked by the place ahead, but may have the doubt that electromagnetic wave leaks equally between this filter B and the second holder E, therefore promptly there is the manufacturer of part that one deck conducting foam I can be set between the second holder E and filter B, but by being provided with of this conducting foam I fill up between the second holder E and filter B the subject of knowledge and the object of knowledge produce between the crack, reach the possibility that certain obstruct electromagnetic wave leaks.But aforementioned conducting foam H, the I of utilizing intercepts electromagnetic design, though have certain effect, in actual manufacturing, still have many problems to take place and remain people and overcome, now its defective is enumerated explanation one by one.
At first, because this filter B that commonly uses in the structure utilizes the end of the second holder E and procapsid A that it is gripped respectively, therefore the design of this procapsid A must cooperate the second holder E, and the conductive film G that is coated with on the filter B must limit and coat a side that contacts with the second holder E, not only cause the degree of difficulty in procapsid A design and the variation to increase, and also increasing manufacturer is selecting and the difficulty of purchasing on the suitable filter B, in addition, because commonly using structure must be between the second holder E and back casing F, and between the second holder E and the filter B one deck conducting foam H and I are set respectively, and this conducting foam H, the kind of I and the specification of size are quite a lot of, can cause the puzzlement of assembling manufacturer equally, especially the place ahead is arranged at the conducting foam I between the second holder E and filter B, because the thickness of filter B itself, also has the distance between filter B and plasma display device D, all will directly influence the effect that filter B is provided, and this is located at the conducting foam I between the second holder E and filter B, will occupy a certain proportion of thickness inevitably, therefore the dealer just must be about to the material of this conducting foam I and thickness earlier and is beforehand with one and considers when design, not only increase the degree of difficulty in dealer's design, will purchase for assembling manufacturer simultaneously the identical conducting foam I of specification also is a very harsh requirement, all suitable inconvenience for both sides.
Except aforementioned disappearance, commonly using structure also has a very serious problem to exist, because the structure of commonly using except the big factory of small part can from Plasmia indicating panel D manufacture and design to the entire product assembling finish all finish on one's own account, the manufacturer (the especially less little factory of scale) of the overwhelming majority, it all is directly after the purchase of Plasmia indicating panel D manufacturer has Plasmia indicating panel D and part, assemble voluntarily again filter B and have a special formed procapsid A, only, thus, it must consider how to cooperate with the second holder E, and filter B gripped closely, not only make the structural design of procapsid A can become more complicated, and its whole electromagnetic obstruct effect also becomes and is difficult to control more, not only make the keyholed back plate difficulty more of quality, and for the manufacturer of frequent change procapsid A moulding white elephant very especially.
