Wherein, be covered with casting glue on the described LED drive plate.
For solution reaches above-mentioned the 3rd purpose, the technical scheme that the utility model adopts is: a kind of LED display is provided, described LED display comprises some LED display Cells, video player and control system, described LED display Cell comprises unit box, be fixed in LED drive plate and the casing power supply that links to each other with the LED drive plate and system's receiving card in the unit box, described LED drive plate comprises drive circuit board, be welded in the LED bulb in drive circuit board front, mount or be welded in the drive IC and driving electrical equipment at the drive circuit board back side, and be welded in signaling interface and power interface on the circuit board, described drive circuit board is latticed hollow out pcb board, and described LED bulb is positioned at latticed intersection point place.
Wherein, be covered with casting glue on the described LED drive plate.
The beneficial effects of the utility model are: adopt the LED display of technical solutions of the utility model, the engraved structure in the middle of its grid will effectively alleviate the weight of display screen, save corresponding manufacturing cost, more convenient to install and dismounting; The printing opacity that can let in air when the curtain wall that is applied to build shows also helps the display screen self-radiating when lighting for buildings is ventilated not influencing.
