in this embodiment, the lattice type nixie tube is also in a shape of "8", as shown in fig. 2, the outer ring of the 8 shape is sequentially divided into a, b, c, d, e, and f sections from the top clockwise, and the cross bar in the middle part is g section; that is, each of the diode groups includes first to seventh light emitting diodes, hereinafter, the first to seventh light emitting diodes of the first diode group are represented by LEDa1, LEDb1, LEDc1, LEDd1, LEDe1, LEDf1, LEDg 1; the first to seventh light emitting diodes in the second diode group are represented by LEDa2, LEDb2, LEDc2, LEDd2, LEDe2, LEDf2, LEDg 2; the first to seventh light emitting diodes of the third diode group are represented by LEDa3, LEDb3, LEDc3, LEDd3, LEDe3, LEDf3, LEDg 3; the first to seventh light emitting diodes of the fourth diode group are represented by LEDa4, LEDb4, LEDc4, LEDd4, LEDe4, LEDf4, LEDg 4; the first to seventh light emitting diodes of the fifth diode group are denoted by LEDa5, LEDb5, LEDc5, LEDd5, LEDe5, LEDf5, LEDg 5; the first to seventh light emitting diodes of the sixth diode group are represented by LEDa6, LEDb6, LEDc6, LEDd6, LEDe6, LEDf6, LEDg 6; the first to seventh light emitting diodes of the seventh diode group are denoted by LEDa7, LEDb7, LEDc7, LEDd7, LEDe7, LEDf7, LEDg 7; the first to seventh light emitting diodes of the eighth diode group are denoted by LEDa8, LEDb8, LEDc8, LEDd8, LEDe8, LEDf8, LEDg 8. And the first to eighth diode groups are represented by LED1, LED2, LED3, LED4, LED5, LED6, LED7, and LED 8.
That is, by lighting one or more light emitting diodes in the diode group, the display of different characters is realized; then, in the conventional lighting method, a high level or a low level is respectively input to different light emitting diodes to light the different light emitting diodes.
In the scheme, the anodes of the plurality of light emitting diodes are connected with the pins, and the cathodes of the N + i-th light emitting diodes in the diode group connected with the nth pin are connected with the N + i + 1-th pin, so that the nth pin, the N + i + 1-th pin and the N + i + 1-th pin are connected only by providing a high level for the nth pin, providing a low level for the N + i + 1-th pin and providing a high resistance state for the rest pins, and the nth pin, the N + i-th light emitting diodes and the N + i + 1-th pin are connected, thereby lightening the N + i-th light emitting diodes in the diode group; and because I is a natural number, namely, through the circuit design, one or more of the light-emitting diodes in the Nth and later light-emitting diodes in the diode group can be lightened only by arranging pins and I/O ports with the same number as that of the diode group (namely, the digit of the nixie tube).
For example, when N is 1 and i is 0, the cathode of the 1 st led in the led group to which the 1 st pin is connected to the 2 nd pin; when N is 1 and i is 1, the cathode of the 2 nd LED in the diode group connected with the 1 st pin is connected with the 3 rd pin; and so on, until N takes 1, i takes 6, the negative pole of the 7 th LED in the diode group that the 1 st pin is connected with the 8 th pin. Then, that is, for the nth and the nth leds in the diode group, different character displays can be realized only by adjusting the high level/low level/high resistance states provided to different pins according to the character display requirements; and the control is realized by connecting each diode group to one pin. Furthermore, the driving of the dot-matrix nixie tube only needs to use pins and I/O ports matched with the digits, namely two 4-digit nixie tubes are driven, only 8 pins and I/O ports are needed, and the improvement of the yield is facilitated due to the relation of pin reduction; the hardware design is simplified, and the cost is reduced; in addition, due to the reduction of the required number of the I/O ports, the utilization rate is improved, and the problems that the subsequent driving process is complicated, the yield is difficult to improve, and the cost is difficult to reduce are solved.
Preferably, the cathode of the mth light emitting diode in the diode group connected to the (N + i + 1) th pin is connected to the mth pin;
wherein M is a natural number greater than or equal to 1 and less than or equal to the N + i.
Further, the value of i cannot be equal to-N.
Specifically, in the present scheme, the cathode of the mth light emitting diode in the diode group connected to the (N + i + 1) th pin is connected to the mth pin, so that during driving, only the (N + i) th pin needs to be provided with a high level, the mth pin provides a low level, and the rest of the pins are provided with a high resistance state, and then the (N + i + 1) th pin, the mth light emitting diode in the diode group connected to the (N + i + 1) th pin, and the mth pin are turned on, so as to light the mth light emitting diode in the diode group connected to the (N + i + 1) th pin; and because M is a natural number which is more than or equal to 1 and less than or equal to the N + I, through the circuit design, one or more of the previous light-emitting diodes before the Nth in the diode group can be lightened only by arranging pins and I/O ports with the same number as that of the diode group (namely, the digit of the nixie tube).
For example, X is 8, when N is 1 and i is 0, N + i +1 is 2, and M is less than or equal to 1, that is, the cathode of the mth led in the diode group connected to the 2 nd led is connected to the mth led, that is, the 1 st led in the diode group connected to the 2 nd led is connected to the 1 st led; when N is 1 and i is 1, N + i +1 is 3, and M is less than or equal to 2, that is, the cathodes of the 1 st to 2 nd leds in the led group connected to the 3 rd led pin are respectively connected to the 1 st and 2 nd led pins; and so on, until N takes 7 and i takes 0, N + i +1 is 8, M is less than or equal to 7, that is, the cathodes of the 1 st to 7 th leds in the led group connected to the 8 th led pin are respectively connected to the 1 st, 2 nd, 3 rd, 4 th, 5 th, 6 th and 7 th led pins. Then, that is, the previous led in the group of leds only needs to adjust the high level/low level/high resistance provided to different pins according to the character requirement for display, so as to realize different character display;
in summary, the light emitting diodes before, nth, and after the nth in the diode group, that is, all the light emitting diodes in the diode group, can realize different character displays by adjusting the high level/low level/high resistance states provided to different pins according to the character display requirements; in the above process, in the case where only one diode group is lighted each time, the interval at which different diode groups are lighted is reduced, that is, the display refresh rate is increased, thereby achieving the effect of visually displaying the desired character.
And the control is realized by connecting each diode group to one pin. Furthermore, the driving of the dot-matrix nixie tube only needs to use pins and I/O ports matched with the digits, namely two 4-digit nixie tubes are driven, only 8 pins and I/O ports are needed, and the improvement of the yield is facilitated due to the relation of pin reduction; the hardware design is simplified, and the cost is reduced; in addition, due to the reduction of the required number of the I/O ports, the utilization rate is improved, and the problems that the subsequent driving process is complicated, the yield is difficult to improve, and the cost is difficult to reduce are solved.

and sequentially inputting high level/low level/high resistance state to different pins according to a plurality of groups of the level identification information.
Specifically, the number of the sets of level identification information is 8, which is the same as the number of the pins; the level identification information is embodied as a two-dimensional character string in which 1 represents a high level, 0 represents a low level, and H represents a high impedance state, such as "1000000H", "0100000H", and the like, and has corresponding meanings of "input high level, low level, high impedance state to 8 pins", "input low level, high level, low level, high impedance state to 8 pins";
