1. A slave driving circuit comprising:
a shift register configured to store a reception packet by bit-by-bit shifting the reception packet, and output the reception packet;
a control circuit configured to generate a latch signal based on a value of a virtual identifier included in the reception packet, and to generate an updated value of the virtual identifier by increasing or decreasing the value of the virtual identifier;
a data register configured to latch and store luminance data include in the reception packet based on the latch signal; and
a driver configured to drive a light source connected to the slave driving circuit based on the luminance data stored in the data register,
wherein the slave driving circuit is configured to generate and output a transmission packet that includes the updated value of the virtual identifier.
