What is an LED digital tube?

A commonly used LED digital tube is composed of seven light-emitting tubes,which is composed of eight figures,with a decimal point inside the eight-section digital tube, Figure is shown as the digital tube shape and internal Structure Chart.From the internal structure,we can see that the digital tube can be divided into a common cathode digital tube and a common anode digital tube two.Figure 10-1b shows a common cathode digital tube circuit,eight LEDs ( 7 strokes and 1 decimal point ) the negative electrode connected together to ground,the decoding circuit according to the need to give different strokes the positive voltage of the LED is plus the positive voltage,so that it can show the corresponding number.Figure 10-1c shows the common anode digital tube circuit,eight LEDs ( 7 strokes and 1 decimal point ) are connected together to ground,the decoding circuit according to the need to give different strokes lED negative voltage plus negative voltage,so that it shows the corresponding digital,LED digital tube,the seven pen segment electrodes are 0 to 9 ( some of the information is capital letters ),the dp is the decimal point,and the figure 10-1a is shown as the digital tube pin arrangement diagram. The field display code of the LED digital tube is shown in Table.( in the table, hexadecimal number system ).
