LED digital tubes are mainly classified in the following ways:

1. According to the control mode, it can be divided into internal control mode (with a microcontroller inside, automatically changing color when powered on) and external control mode (requiring an external controller to change color).

2. According to the way of change, it can be divided into fixed color, rainbow, and full-color; Fixed colors are used for outlining, while full-color colors can be used for outlining and can also be used to display text, videos, etc. on a screen.

3. According to size: there are D50 and D30, which are diameters; Basically 1 meter in length (customizable); This needs to be selected according to actual needs.

4. According to internal controllability, there are 1.6-meter segments, 1.8-meter segments, 1.2-meter segments, 1.16-meter segments, and 1.32-meter segments. That is to say, there are several sections within a 1-meter pipe that can be independently controlled; The more 1-meter segments there are, the better the video effect. If the density is low, or if you want to achieve some chasing effect, you can do 1.6 meters.

5. According to the number of LEDs, there are 96 lights per meter and 144 lights per meter; The more lights there are, the better the effect. Generally, full-color products use 144 lamps per meter.

6. According to power supply: divided into high voltage power supply (direct 220V power supply) and low voltage power supply (12V power supply, 220V power supply requires switching power conversion); Generally, low voltage power supply is chosen for its reliability and stability, while high voltage power supply is prone to burning out.

7. Divided by pixels: A 1-meter 16 segment lamp tube means that a 1-meter lamp tube has 16 pixels. Generally, there are 6-segment digital tubes, 8-segment digital tubes, 12 segment digital tubes, 16 segment digital tubes, 32 segment digital tubes, etc., with 16 segment digital tubes being more common. A 6-segment digital tube is generally used for contour projects.
