In specific implementation, as shown in fig. 1, the first sub-nixie tube array a and the second sub-nixie tube array are divided into a first sub-nixie tube array a and a second sub-nixie tube array B by the nixie tube arrays according to the LED nixie tube conducting currents, the LED nixie tubes with the same flow direction are divided into the first sub-nixie tube array a, the opposite LED nixie tubes are divided into the second sub-nixie tube array B, the two sub-nixie tube arrays are split along the diagonal line of the original nixie tube array during splitting, the first sub-nixie tube array a and the second sub-nixie tube array B formed after splitting have different ports, that is, the first sub-nixie tube array a formed after splitting has its own driving port, the second sub-nixie tube B formed after splitting has its own splitting port, so as to realize that the LED nixie tubes in the first sub-, the LED nixie tubes in the second sub-nixie tube array B carry out dot-matrix reverse leakage current measurement through split ports; it should be noted that, in the embodiment of the present invention, the number of LED nixie tubes in the first sub-nixie tube array a formed after splitting is the same as the number of LED nixie tubes in the second sub-nixie tube array B formed after splitting, and the nixie tube array before splitting does not limit the number of LED nixie tubes, and the embodiment of the present invention takes a nixie tube array in a form of an 8 × 8 matrix as an example.
Further, as can be seen from fig. 1, the anodes of all the columns of nixie tubes of the first sub-nixie tube array a formed after splitting are connected in common and are connected with one driving port, and the cathodes of a plurality of nixie tubes in each row are connected in common and are connected with the corresponding driving port, for example, the anodes of all the first columns of nixie tubes in the first sub-nixie tube array a are connected with the driving port LED0, the anodes of all the second columns of nixie tubes are connected with the driving port LED1, the cathodes of all the second rows of nixie tubes in the first sub-nixie tube array a are connected with the driving port LED2, the cathodes of all the third rows of nixie tubes are connected with the driving port LED3, and so on.

In this embodiment, the nixie tube array is split according to the conducting current direction of the LED nixie tube, so that the first sub-nixie tube array a formed after splitting has its own driving port, the second sub-nixie tube B formed after splitting has its own splitting port, thereby realizing that the LED nixie tube in the first sub-nixie tube array a can directly measure the reverse leakage current in a dot matrix form through the LED driving port, and the LED nixie tube in the second sub-nixie tube array B measures the reverse leakage current in a dot matrix form through the splitting port, thereby ensuring that when measuring the reverse leakage current of any one LED nixie tube, there is no influence of any forward conducted LED nixie tube current, and thus improving the measurement precision and accuracy of the reverse leakage current of the LED nixie tube.
Further, as an embodiment of the present invention, the plurality of driving ports of the first sub-nixie tube array a and the plurality of splitting ports of the second sub-nixie tube array B are connected in a one-to-one correspondence manner through wires.
In the embodiment of the present invention, the split port of the second sub-nixie tube array B may be used as a reverse current measurement point to provide a reverse current excitation input, and after the LED nixie tube is measured, the split port may be directly connected to the corresponding LED driving port at the board level through a wire, as shown in fig. 4, so as to recover the normal use function of the serial dot matrix LED.
In the embodiment, the split port is arranged in the split second sub-nixie tube array B, so that after the LED nixie tubes in the second sub-nixie tube array complete reverse leakage current measurement through the split port, the LED nixie tubes can be connected with the LED driving port through the wires, the convenience and the accuracy of measurement are guaranteed, the function of an actual serial dot matrix LED nixie tube is not influenced, and the split port is simple, visual and high in value.
Fig. 2 shows a method for measuring a reverse leakage current of a nixie tube according to an embodiment of the present invention, where the method for measuring a reverse leakage current of a nixie tube is based on the LED nixie tube structure shown in fig. 1, so that a detailed description of the LED nixie tube structure can be described with reference to fig. 1, where only an implementation process of the method is described in detail, and the implementation process is as follows:
step S21: and determining the sub-nixie tube array where the nixie tube to be detected is located.
In the embodiment of the present invention, please refer to fig. 1 and fig. 2, because the first sub-nixie tube array a and the second sub-nixie tube array B are divided according to the flow direction of the conducting current, in order to make the LED nixie tube in any one array not affected by the forward conducting current of other LED nixie tubes when performing the reverse leakage current measurement, before the measurement, it is necessary to determine the sub-nixie tube array where the nixie tube to be measured is located, that is, whether the nixie tube to be measured is the LED nixie tube in the first sub-nixie tube array a or the LED nixie tube in the second sub-nixie tube array B.
Specifically, the determining of the sub-nixie tube array where the nixie tube to be tested is located includes:
and acquiring the port type of the to-be-detected nixie tube connected in the nixie tube array, and determining the sub-nixie tube array where the to-be-detected nixie tube is located according to the port type.
In the embodiment of the present invention, since the split first sub-nixie tube array a and the split second sub-nixie tube array B have respective ports, when the sub-nixie tube array where the nixie tube to be tested is located is determined, it is possible to detect whether the port connected to the nixie tube to be tested is a drive port or a split port, if the port connected to the nixie tube to be tested only has a drive port, it indicates that the nixie tube to be tested is located in the first sub-nixie tube array a, and if the port connected to the nixie tube to be tested has a drive port and a split port, or only has a split port, it indicates that the nixie tube to be tested is located in the second sub-nixie.
In this embodiment, the sub-nixie tube array where the nixie tube to be measured is located is determined according to the type of the port to which the nixie tube to be measured is connected, so that the position of the nixie tube to be measured can be found in the corresponding sub-nixie tube array, and the reverse leakage current measurement can be performed quickly.
Step S22: and acquiring the row position and the column position of the to-be-detected nixie tube in the sub-nixie tube array.
In the embodiment of the present invention, the row position of the to-be-tested nixie tube in the sub-nixie tube array refers to a specific row number of the to-be-tested nixie tube in the sub-nixie tube array, and the column position of the to-be-tested nixie tube in the sub-nixie tube array refers to a specific column number of the to-be-tested nixie tube in the sub-nixie tube array.
Step S23: and inputting reverse voltage to the corresponding port of the column position where the nixie tube to be detected is positioned, and inputting forward voltage to the corresponding port of the row position where the nixie tube to be detected is positioned.
In the embodiment of the present invention, after the row position and the column position of the to-be-measured nixie tube in the sub-nixie tube array are determined, a reverse voltage can be input to the corresponding port of the column position of the to-be-measured nixie tube, and a forward voltage can be input to the corresponding port of the row position of the to-be-measured nixie tube, so as to measure the reverse leakage current of the to-be-measured nixie tube.
For example, when it is determined that the to-be-measured nixie tube is a certain LED nixie tube in the first sub-nixie tube array a, the reverse current value of the nixie tube can be measured only by applying positive and negative voltages to the two LED driving ports corresponding to the nixie tube; when the nixie tube to be measured is determined to be a certain LED nixie tube in the second sub-nixie tube array B, the reverse current value of the nixie tube can be measured only by applying positive and negative voltages to the two splitting connection points corresponding to the nixie tube.
Specifically, as an embodiment of the present invention, if the sub-nixie tube array where the nixie tube to be tested is located is the first sub-nixie tube array a, the inputting the reverse voltage to the corresponding port of the column position where the nixie tube to be tested is located, and the inputting the forward voltage to the corresponding port of the row position where the nixie tube to be tested is located includes:
and inputting reverse voltage to the corresponding driving port at the column position of the nixie tube to be detected, and inputting forward voltage to the corresponding driving port at the row position of the nixie tube to be detected.
For example, when the reverse current of the LED nixie tube X in the first sub-nixie tube array a needs to be measured, only the forward voltage needs to be applied to the driving port LED4, and the reverse voltage needs to be applied to the driving port LED 1.
Specifically, as another embodiment of the present invention, if the sub-nixie tube array where the nixie tube to be tested is located is the second sub-nixie tube array B, and the nixie tube to be tested is located in the first row in the second sub-nixie tube array, the inputting the reverse voltage to the corresponding port of the column position where the nixie tube to be tested is located, and the inputting the forward voltage to the corresponding port of the row position where the nixie tube to be tested is located includes:
and inputting reverse voltage to the corresponding split port at the column position of the nixie tube to be detected, and inputting forward voltage to the corresponding driving port at the row position of the nixie tube to be detected.
For example, when the reverse current of the LED nixie tube W in the second sub-nixie tube array B needs to be measured, only the forward voltage needs to be applied to the driving port LED0, and the reverse voltage needs to be applied to the splitting port T1; similarly, when the reverse current of the LED nixie tube Z in the second sub-nixie tube array B needs to be measured, only the forward voltage needs to be applied to the split port T4, and the reverse voltage needs to be applied to the LED7, and the measured current value is only the reverse current of the LED nixie tube Z, and there is no influence of any forward conducting current.
Further, as another embodiment of the present invention, if the sub-nixie tube array where the nixie tube to be tested is located is a second sub-nixie tube array, and the nixie tube to be tested is not located in the first row of the second sub-nixie tube array, the inputting a reverse voltage to the corresponding port of the column position where the nixie tube to be tested is located, and inputting a forward voltage to the corresponding port of the row position where the nixie tube to be tested is located includes:
and inputting reverse voltage to the corresponding splitting port at the column position of the nixie tube to be detected, and inputting forward voltage to the corresponding splitting port at the row position of the nixie tube to be detected.
For example, when the reverse current of the LED nixie tube Y in the second sub-nixie tube array B needs to be measured, only the forward voltage needs to be applied to the split port T1, and the reverse voltage needs to be applied to the split port T4, and the measured current value is only the reverse current of the LED nixie tube Y, and there is no influence of any forward conducting current.
Step S24: and measuring the reverse leakage current of the nixie tube to be measured according to the input forward voltage and the input reverse voltage.
In the embodiment of the present invention, after the corresponding forward voltage and the reverse voltage are input to the port to which the to-be-tested nixie tube is connected, a current flows through the to-be-tested nixie tube, and the current is measured, so that the reverse leakage current of the to-be-tested nixie tube can be obtained.
In this embodiment, when measuring any LED nixie tube in the first sub-nixie tube array a of the group a, the method for measuring reverse leakage current of the nixie tube only needs to apply positive and negative voltages to the two LED driving ports corresponding to the nixie tube to measure the reverse current value of the nixie tube, and when measuring any LED nixie tube in the second sub-nixie tube array B, the method only needs to apply positive and negative voltages to the two split ports corresponding to the nixie tube to measure the reverse current value of the nixie tube, so that when measuring the reverse current of any LED nixie tube, there is no influence of any forward conducting LED nixie tube current, the method is simple to operate, and the measurement accuracy is high.
