According to statistics, among the full-color LED display screen products, the scanning methods are 1/16, 1/8, 1/4, 1/2, static. How to distinguish between different LED full-color display scanning methods? One of the simplest methods is to count the number of LEDs of the LED electronic display screen unit board and the number of 74HC595. Of course, it also needs to be analyzed in conjunction with the corresponding LED drive scanning characteristics.
Calculation method: the number of LEDs divided by the number of 74HC595 and then divided by 8 = fractional scanning
The real pixel LED display screen corresponds to the virtual LED electronic display screen: in a nutshell, the real pixel screen refers to the red, green and blue light-emitting tubes constituting the display screen, each of which ends in only one pixel Imaging application to obtain satisfactory brightness.
Virtual pixels use software algorithms to control the end of each color luminous tube to participate in the imaging of multiple adjacent pixels, and then use fewer lamps to complete a larger resolution, which can increase the resolution of the display by four times.
There are 16 scans, 8 scans, 4 scans, etc. on the side of the full-color LED display screen series products, and there are also differences between the following:
16 * 8 * (2 + 1 + 1) = 512 lights, 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 scan virtual.
3. If 8 MBI5026 chips are used, it is dynamic 1/4 scan virtual. If it is a full-color LED display panel, two red lights are connected in series:
4. Use 24 MBI5026 chips, which are static real pixels.
5. With 12 MBI5026 chips, it is a dynamic 1/2 scan real pixel.
6. Use 6 MBI5026 chips, which are dynamic quarter-scan real pixels.
