1. 1/16 scanning routing method

16 scan routing method

To achieve 1/16 scanning, there are usually 4 signals, A, B, C, and D. Then you can choose 1 4-16 decoder or 2 3-8 decoders to achieve 16-line scanning.

2. 1/8 scan routing method

Generally, there are three signals on the circuit board: A, B, and C. Then, a 3-8 decoder can be used to achieve 1/8 scanning.

3. 1/4 scan routing method

Generally, there are two signals A and B on the circuit board, and then a 2-4 decoder can be used. If a decoder is not used, four signals A, B, C, and D are required, that is, one row is selected for each signal.

Illustration of the colorful LED stage screen

　　One of the functions of the stage LED screen: enriching the performance content. As an extension and supplement to the stage performance, LED enriches the content of the performance and provides the audience with information beyond the performance itself. At the same time, the audience can get rid of the single
