Scanning mode: the ratio of the number of rows lighted at the same time to the number of rows in the whole area in a certain display area.

Indoor full color is generally 1/8, 1/16, 1/32 scan, and outdoor color is generally static, 1/2, 1/4 scan.

At present, there are two driving modes of LED display on the market, 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 is generally used in domestic HC595, Taiwan MBI5026, Japan Toshiba TB62726, which is generally 1/2 sweep, 1/4 sweep, 1/8 sweep and 1/16 sweep. For example, the pixel of a common full-color module is 16*8 (2R1G1B). If it is driven by MBI5026, the module USES: 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 dynamic 1/2 scanning virtual;

(3) if 8 MBI5026 chips are used, it is dynamic 1/4 scanning virtual; if two red lights are connected on the board;

(4) with 24 MBI5026 chips, it is a static real pixel;

(5) with 12 MBI5026 chips, it is a dynamic 1/2 scanning pixel;

(6) with 6 MBI5026 chips, it is a dynamic 1/4 scanning pixel; In the LED panel, the scanning mode is 1/16, 1/8, 1/4, 1/2, static.

How do you tell? One of the easiest ways to do this is to count the number of leds on the board and the number of 74HC595.

Calculation method: the number of leds divided by the number of 74HC595 divided by 8 = a fraction of a scan

The real pixels correspond to the virtual pixels: in simple terms, the real pixels screen refers to the red, green, and blue leds that make up the display. Virtual pixels use software algorithms to control the luminescent tubes of each color and eventually participate in the imaging of multiple adjacent pixels, thus enabling the realization of larger resolution with less lamp tubes and the enhancement of display resolution by four times.
