The LED screen we supply can be installed in areas covered by wireless signals. Distant control of the LED screen can be maintained through wireless signals, GSM signals or GPRS signals.
The screen uses dotted light-emitting diodes and has memory for words or images, which can be displayed one after another in an upward direction or in an forward direction.
If the LED screen is controlled by way of short message, it can be applied in any area that is covered by telecom network. It is widely used in railway system, advertising boards, and other places.
