When the singlechip is used for scanning and displaying the nixie tube, the characters are taken as a unit, namely the nixie tube is taken as a unit, each light emitting diode of each character (each nixie tube) is sequentially scanned section by section, a certain lighting time is kept after each character is lighted, the character is closed, the rest other characters are continuously lighted and closed in sequence within the visual delay time period of human eyes, and finally, the visual effect generated on the human eyes is that all the characters are simultaneously displayed.

The above is one display period, and the display effect is continued if the display period is continuously executed.
in some embodiments, gating all of the ith display segments of the nixie tubes comprises: and (4) gating the cathodes of the ith display segment of all the nixie tubes. Optionally, the cathodes of the ith display segment of all the nixie tubes are connected together to form a common cathode of the ith display segment, and the common cathode is gated. The ith display segment of all the nixie tubes can be gated only by performing gating operation on the common cathode once, and when the number of the nixie tubes is large, the method can greatly improve the gating speed, so that the display speed is improved.
in some embodiments, gating all of the ith display segments of the nixie tubes comprises: and (4) gating the anodes of the ith display segments of all the nixie tubes. Optionally, the anodes of the ith display segments of all the nixie tubes are connected together to form a common anode of the ith display segment, and the common anode is gated. The ith display segment of all the nixie tubes can be gated only by performing gating operation on the common anode once, and when the number of the nixie tubes is large, the method can greatly improve the gating speed, so that the display speed is improved.
in some embodiments, gating the nixie tube whose display content includes the ith display segment comprises: when the cathodes of the ith display segments of all the nixie tubes are gated, the gated display content comprises the common pole of the nixie tubes of the ith display segments, and the common pole is formed by connecting the anodes of all the display segments in the same nixie tube; when the anodes of the ith display segments of all the nixie tubes are gated, the gated display content comprises the common pole of the nixie tubes of the ith display segments, and the common pole is formed by connecting the cathodes of all the display segments in the same nixie tube.
when the ith display segment has a common cathode, connecting the anodes of all the display segments in each nixie tube together to form a common electrode (COM) of each nixie tube, and gating the common electrode of the nixie tube with display contents including the ith display segment; when the ith display segment has a common anode, the cathodes of all the display segments in each nixie tube are connected together to form a common pole of each nixie tube, and the common pole of the nixie tube of which the display content comprises the ith display segment is gated. A nixie tube can have two forms of common anode and common cathode. In the common-anode nixie tube, the anodes (or anodes) of all display segments are connected together, and the other joints are the cathodes (or cathodes) of the display segments. When the nixie tube needs to be lightened, different display sections can be controlled to be lightened only by gating the common anode and different cathodes, so that the nixie tube is controlled to display different contents. In the common cathode nixie tube, the cathodes (or negative electrodes) of all display segments are connected together, and the other joint is the anode (or positive electrode) of each display segment. When the nixie tube needs to be lightened, different display sections can be controlled to be lightened only by gating the common cathode and different anodes, so that the nixie tube is controlled to display different contents. Therefore, after the ith display segment is gated, if the ith display segment needs to be lighted up by the nixie tube, the common anode or the common cathode of the nixie tube is gated, and the ith display segment of the nixie tube can be lighted up.
In some embodiments, the common pole of each nixie tube is connected to a respective bit strobe control circuit, and the gating of the common pole of the nixie tube is controlled by the bit strobe control circuit. When the bit gating control circuit corresponding to the nixie tube to be displayed starts gating, the nixie tube can be gated, and when the display section of the nixie tube is also gated, the gated display section of the nixie tube can be lightened, so that the font is displayed.
In some embodiments, each bit gating control circuit is controlled by an independent input/output I/O line, when the singlechip outputs the font code, all nixie tubes receive the same font code, but which nixie tube displays the font code depends on the control of the singlechip on the bit gating control circuit.
In some embodiments, strobing the common pole of the nixie tube whose display content contains the ith display segment comprises: determining that the display content comprises a nixie tube of the ith display segment; gating the common pole of the nixie tube.
Before the nixie tubes are gated, whether the display content of each nixie tube contains the ith display segment needs to be determined so as to gate the correct nixie tube to achieve correct display.
In some embodiments, determining that the display content includes a nixie tube for the ith display segment comprises: obtaining a scanning array corresponding to the ith display segment; and determining that the nixie tube corresponding to the common pole information contained in the scanning array is the nixie tube of which the display content contains the ith display segment.
And splitting the display content of each nixie tube according to each display segment to form each display segment information corresponding to the display content. Optionally, when the display content includes the display segment 1, the display segment 1 information of the nixie tube is the common pole of the nixie tube (COMn, n represents the serial number of the nixie tube); when the display content does not include the display segment 1, the display segment 1 information of the nixie tube is 0. And respectively writing the information of each display segment of all the nixie tubes into the scanning array corresponding to each display segment, and determining the nixie tubes to be lightened through the scanning array in a scanning period.
