At synchronization, the voltage of a connecting line in N bar connecting line, is only had to be that just the voltage of a connecting line is negative; Thus the LED lamp unit controlled in corresponding two LED lamp unit connected with these two connecting lines is lighted, all the other LED lamp unit are in OFF state.
