Its further technical scheme is: described conductive layer is the conduction enamelled coating.
Its further technical scheme is: the outside surface of described casing all is coated with for antirust protective seam except described installation region.
Its further technical scheme is: the inside surface of described casing and installation region are coated with the rust-proof conductive layer.
Its further technical scheme is: described rust-proof conductive layer is the iron zinc coat.
Its further technical scheme is: described power supply and system card are installed in respectively primary importance and the second place in the described casing, and described primary importance and the second place are positioned at differing heights.
Its further technical scheme is: be provided with a shielding box in the described casing, described system card is installed in the described shielding box.
Its further technical scheme is: the input end of described power supply is connected with a wave filter.
Compared with prior art, the LED display that the utility model can improve EMC arranges conductive layer with the junction of casing and makes the LED module and casing consists of the galvanic circle on the LED module, thereby whole LED display becomes large shield, can greatly improve EMC, reduce the harm that electromagnetic radiation produces the user.
By following description also by reference to the accompanying drawings, it is more clear that the utility model will become, and these accompanying drawings are used for explaining embodiment of the present utility model.
