An interactive light emitting diode display having a plurality of individual light-emitting diode units. Each light-emitting diode unit further has at least one light-emitting diode die, an individual driving circuit operative to drive the light-emitting diode die, a micro-controller unit operative to transmit a driving signal to the driving circuit and an activation/inactivation signal, and a transceiver operative to transmit the activation/inactivation signal to activate/inactivate another light-emitting diode unit, and to receive an external activation/inactivation signal.
