So the LED display cabinet is composed of the basic unit of the screen body. Using LED cabinet for benefits as follows: one is to facilitate scheduling, aging, site maintenance; 2 it is convenient for packaging, transport; 3 it is installation convenient disassembly. Waterproof outdoor LED display in front of the box body is equipped with a display module, the box body internal fixed display driver circuit board. Switching power supply installed in the case of the back cover. On the back cover of the enclosure also install a fan, shutters, etc. Enclosure used inside and outside surface coating processing, anti-corrosive, moistureproof, prevent oxidation, flame retardant function, guarantees the safety of the work for the screen body.

Another LED display cabinet structure perishable parts roughly screen body part of the metal column, circuit boards, terminal blocks, connectors; Sensitive to water vapor of the components for the circuit boards, electronic components pins. Suite, other parts of engineering plastics ( Polycarbonate) , epoxy resin, rubber, etc. , is not sensitive to water vapor. The current trend is that more and more customers in the LED display has more demand on the waterproof enclosure structure, began to thin, easy to remove the housing development, but from the professional point of view to analysis, not closed, the light we will be able to have waterproof effect, enclosure structure just dust, prevent a foreign body, and so on.
