How to identify the scanning method of the led display? At present, the driving methods of the led display on the market are static scanning and dynamic scanning. Static scanning is divided into static real pixels and static virtual, and dynamic scanning is also divided into dynamic real image and dynamic virtual; The driving device generally uses domestic HC595, Taiwan MBI5026, Japan Toshiba TB62726, generally has 1/2 scan, 1/4 scan, 1/8 scan, 1/16 scan.

　　How to identify the scanning method of the led display?

　　Explanation: A commonly used full-color module has a pixel size of 16*8 (2R1G1B). If it is driven by MBI5026, the total number of modules used is:

　　16*8*(2+1+1)=512, MBI5026 is a 16-bit chip, 512/16=32(1) If 32 MBI5026 chips are used, it is static virtual

　　 (2) If 16 MBI5026 chips are used, it is a dynamic 1/2 scan virtual (3) If 8 MBI5026 chips are used, it is a dynamic 1/4 scan virtual if two red lights on the board are connected in series

　　(4) 24 MBI5026 chips are used, which are static real pixels

　　(5) Use 12 MBI5026 chips, which are dynamic 1/2 scan pixels

　　(6) 6 MBI5026 chips are used, which is a dynamic 1/4 scanning real pixel

　　On the LED unit board, the scanning methods are 1/16, 1/8, 1/4, 1/2, static. How to distinguish? One of the easiest ways is to count the number of LEDs on the unit board and the number of 74HC595.

Calculation method: the number of LEDs divided by the number of 74HC595 and then divided by 8 = a fraction of scanning real pixels correspond to virtual: in simple terms, the real pixel screen refers to the red, green and blue lights that make up the LED display Each type of light-emitting tube in the tube finally only participates in the imaging use of one pixel to obtain sufficient brightness.

　　Virtual pixel is the use of software algorithms to control the light-emitting tube of each color to finally participate in the imaging of multiple adjacent pixels, so that a larger resolution can be achieved with fewer tubes, and the display resolution can be increased by four times.

　　Look at the number of ICs in a single module. The static drive IC controls 16 points. If a single module has 32*16 points and there are only 8 ICs, then 32*16/16/8=4, that is, 1/4 scan.
