Digital tube, also known as glow tube, is an electronic device that can display numbers and other information. The glass tube comprises an anode made of metal mesh and a plurality of cathodes. The cathode shape of most nixie tubes is digital. The tube is filled with a low pressure gas, usually mostly neon, plus some mercury and / or argon. To charge a cathode, the digital tube will emit color light, depending on the gas in the tube, generally orange or green. So how to use a digital tube to display numbers?
Digital tube display
1. First, we need to understand the structure of a digital tube.
2. Common anode and common cathode digital tube, the common end is the middle pin. The common cathode digital tube needs to be connected to GND, and the common anode digital tube needs to be connected to VCC.
3. Nixie tube is a kind of semiconductor light-emitting device, and its basic unit is light-emitting diode. According to the number of segments, the nixie tube is divided into seven segment nixie tube and eight segment nixie tube. The eight segment nixie tube has one more LED unit (one more decimal point) than the seven segment nixie tube
4. The common anode nixie tube is a kind of nixie tube that connects the anodes of all light-emitting diodes to form a common anode (COM). When the common anode nixie tube is applied, the common pole com should be connected to + 5V. When the cathode of a field led is at low level, the corresponding field will light up. When the cathode of a certain field is at high level, the corresponding field will not be on.
The common cathode nixie tube is a kind of nixie tube which connects the cathodes of all light-emitting diodes to form a common cathode (COM). When the common cathode nixie tube is applied, the common pole com should be connected to the ground wire GND. When the anode of a field led is at high level, the corresponding field will light up. When the anode of a field is low, the corresponding field will not be on.
