1. A light emitting diode (LED) package comprising:
at least one LED chip; and
an active electrical element electrically connected to the at least one LED chip, the active electrical element configured to receive serial communication from a data stream, the serial communication comprising a command for controlling the at least one LED chip, and wherein the active electrical element is configured to generate a synchronization signal within the active electrical element for implementing the command that is correlated to data within the data stream, wherein the synchronization signal is configured to activate a counter within the active electrical element for implementing the command at a delayed time with respect to when the command is received from the data stream, and wherein the counter is configured to count the synchronization signal within the active electrical element;
wherein the active electrical element is configured to receive the data stream from a master controller and the data stream is derived from one or more color signals and one or more of a horizontal clock signal, a vertical clock signal, and a pixel clock signal.
