Direction is propagated, and braced frame 110 is grounded, so that interference electromagnetic wave is introduced underground, is avoided and is sent out in interference electromagnetism wave direction air
It penetrates.Conductive sheet 133 is arranged and embeds the mode of diversion column 134 between lamp plate 131 and bottom case 132, while in bottom case 132, it is real
The interior design for having showed electromagnetic diversion is connected ground terminal 1311 and braced frame 110 by copper wire or gold thread compared to traditional
The mode connect avoids the complexity of configuration on LED display 10, without laying additional route.Meanwhile it dismantling
In the case where display unit 130, EMC structure is externally invisible, and in disassembly process, and EMC structure also only has slight mill
Damage, will not damage EMC structure, and compared to the mode of traditional gold thread connection, EMC structure will not tearing open to LED display 10
The process of unloading brings interference.Bottom case 132 embeds the mode of diversion column 134, so that the plastics of lighter weight can be used in bottom case 132
It is made from material, to achieve the purpose that reduce cost, reduce weight and can make display unit while reducing weight
130 with being easy to splice, and is also easier to realize splicing between different LED displays 10.
Each technical characteristic of embodiment described above can be combined arbitrarily, for simplicity of description, not to above-mentioned reality
It applies all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, all should be considered as described in this specification.
The embodiments described above only express several embodiments of the present invention, and the description thereof is more specific and detailed, but simultaneously
It cannot therefore be construed as limiting the scope of the patent.It should be pointed out that coming for those of ordinary skill in the art
It says, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to protection of the invention
Range.Therefore, the scope of protection of the patent of the invention shall be subject to the appended claims.
