1. A display, comprising:
a control element configured to provide a serial communication signal; and
a plurality of light-emitting diode (LED) packages arranged to receive the serial communication signal from the control element, each LED package of the plurality of LED packages comprising:
at least one LED;
an LED driver electrically coupled with the at least one LED; and
an active electrical element electrically connected to the at least one LED, the active electrical element configured to receive a reset signal that comprises at least one pulse of the serial communication signal, and the reset signal is embedded in the serial communication signal with brightness level data or color select data received by the active electrical element at a common input port of the active electrical element, wherein the active electrical element comprises an input/output buffer electrically coupled between the common input port and the LED driver;
wherein the reset signal is configured to initiate a reset action that restarts the active electrical element of a first LED package of the plurality of LED packages from an error state.
