LED Display (light-emitting diode display) is a screen display technology that uses a panel of LEDs as the light source. Their brightness allows them to be used outdoors where they are visible in the sun store signs and billboards, and in recent years they have also become commonly used in destination signs on public transport vehicles, as well as variable-message signs on highways.

For led display consist by following :

1.Cabinet(Cabinet used to assembly the components together,like module,receiving card,power supply ,fan etc and have protect function.)

2.LED module (Consist by LED lamp, IC,PCB Board,Capacitance, resistance ,Signal socket ,power socket ,led module’s bottom case etc. It’s a most important part of led display.)

3.Sending card (Control system. Usually, sending card is installed on the PCI-E slot of the control PC, collects and transfers data to LED screen . People may use an external sending card with box outside. We call this as sender box or sending box. Its function is the same as sending card. The only difference is that it is external.)

4.Receiving card ( control system. Receiving card is installed in each cabinet of LED screen, receives the data from the sending card and runs the LED screen. )


5.Hub card. ( control system. Hub card is connected onto receiving card, distributes data to LED modules.)

6.web cable ( connect the sending card and receiving card. Use to transfer the signal )

7.220V Power cable ( connect outside voltage to power supply)

8.Three terminal block (used to connect the 220V power cable)

9.5V Flat cable ( connect receiving or hub card to module,module to module, use for signal transfer)

10.5V power cable( connect power supply to module, use for module to module’s power transfer)

11.Power supply ( use to transfer the power voltage which module acceptable. Usually from 220v change to 5v )

12.Fan ( for cooling the led screen)

13.Power / signal indicator(Check the power/signal cable if connected properly)
