Talk about: several situations of full color LED electronic display screen driving scanning

According to statistics, there are 1 / 16, 1 / 8, 1 / 4, 1 / 2, static scanning methods in full-color LED electronic display screen series

products. How to distinguish between different scanning methods of LED full-color display? One of the simplest methods is to

count the number of LEDs and the number of 74HC595 in the LED electronic display screen unit board. Of course, it is necessary

to analyze the corresponding LED drive scanning characteristics.

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

The real pixel LED electronic display screen and virtual LED electronic display screen are corresponding: in brief, the real image

plain screen refers to the red, green and blue light emitting tubes that constitute the display screen, and each of them only

participates in the imaging application of one pixel at the end, so as to obtain the satisfied brightness.

Virtual pixel is to use software algorithm to control the end of each color led to participate in the imaging side of multiple adjacent

pixels, and then make use of fewer lamps to complete the larger resolution, which can make the display resolution improve four

times.
There are 16 scans, 8 scans and 4 scans in the full-color LED electronic display screen series, and there are also differences

between them
1、 The scanning methods of LED electronic display screen are different;
2、 The brightness of LED electronic display screen is different (16S less than 8s, less than 4S);
3、 The quotation is not the same, maybe it is understood that the number of driver IC chips used is different (the same type of

16S is less than 8s, less than 4S)
The LED electronic display screen in the current market can be roughly divided into static scanning and dynamic scanning! Static

scanning is divided into static real pixel and static virtual! Dynamic scanning is also divided into dynamic real image and dynamic

virtual image. There are 2 scans, 4 scans, 8 scans and 16 scans.
For example, the pixel of a field PH16 full-color module is 16 * 8 (2R1G1B). If the module is driven by mbi5026, the module uses:
16 * 8 * (2 + 1 + 1) = 512 lamps, mbi5026 is 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 scan virtual
3. If 8 mbi5026 chips are used, it is dynamic 1 / 4 scan virtual
If the two red lights on the full-color LED electronic display unit board are connected in series
4. With 24 mbi5026 chips, it is a static real pixel
5. With 12 mbi5026 chips, it is a dynamic 1 / 2 scan real pixel
6. With 6 mbi5026 chips, it is a dynamic 1 / 4 scanning pixel [LED electronic display screen]
