1. A light emitting diode (LED) string control system, comprising:
an LED string, comprising a plurality of LED modules, and
a control module, coupled to the LED modules, and configured to provide a control signal to control the LED modules to generate lighting behavior based on a light command,
wherein the light command is composed of a plurality of first digital logics and a plurality of second digital logics in a specific sequence; the control module respectively provides a plurality of first voltage levels and a plurality of second voltage levels to form the control signal based on the first digital logics and the second digital logics of the light command,
wherein when the light command comprises the first digital logics and the second digital logics interlaced to each other, the control module directly adjusts the voltage level of the control signal from the first voltage level to the second voltage level or from the second voltage level to the first voltage level based on the interlaced sequence,
wherein when the light command comprises consecutive first digital logics and/or consecutive second digital logics, the control module provides a third voltage level as a distinction voltage level for distinguishing two consecutive first voltage levels and/or two consecutive second voltage levels.
