The working principle is as follows. N1～Nn are 9-bit micro digital switch, when being set, each switch can only links to 1 bit(1~9), others are cut off. When all 1~9 are cut off, it indicates 0 . For example, if the front 3-bit digital pipes of N1～N3 indicate 098 , then N1 is off, the 9th bit of N2 is on, the 8th bit of N3 is conducting; the other set method is the same. Among the screens, N1～Nn are 1.5 inch highly bright overcast pipes, which are corresponding to N1~Nn.
