What communication methods are usually used in LED displays?

(1) Staff use portable computers to update data at the equipment site. The disadvantage of this data transmission method is that it is difficult to update the display data in real time, and it is difficult to detect faults in the LED display in time. It also increases the labor intensity of the staff and increases the labor costs of enterprise operations. (2) The LED display screen is connected to the Internet through an Ethernet line to communicate with the server-side computer connected to the Internet, and the computer is used to transmit data to the LED display screen through the Internet. This data transmission method requires Ethernet cabling, which has the disadvantages of inconvenient installation and relatively expensive maintenance costs. (3) Control the LED display screen through short messages. The disadvantage of this data transmission method is that it is difficult to edit short messages and the amount of data transmitted is relatively small.
