The calculation method: the number of led divided by the number of 74HC595 divided by 8 = a fraction of the actual pixel scan LED electronic screen is corresponding to the virtual LED electronic display: In short, the real pixel screen refers to constitute the LED display Each of the three types of LEDs in the red, green, and blue LEDs of the panel participates in the imaging of one pixel only to achieve satisfactory brightness.
The virtual pixel is the imaging edge that uses a software algorithm to manipulate the end of the light-emitting tube for each color to participate in multiple adjacent pixels, and then allows the display resolution to be quadrupled by using fewer tubes to complete the larger resolution.
There are 16 sweeps, 8 sweeps, and 4 sweeps in the full-color LED display series, and there are differences in the following:
1, LED screen scanning method is not the same;
2, LED screen brightness is not the same (16s less than 8s less than 4s)
3, the quote is not the same, perhaps interpreted as the number of driver IC chips used is not the same (the same type of 16s is less than 8s is less than 4s)
Current LED display on the market can be roughly divided into two methods: static scanning and dynamic scanning! Static scanning is further divided into static real pixels and static virtual! Dynamic scan is also divided into dynamic real images and dynamic virtual, with 2 sweeps, 4 sweeps, 8 sweeps, and 16 sweeps.
Elucidation: The color of a full-color module used in an outdoor PH16 full-color LED display is 16*8 (2R1G1B). If MBI5026 is used for driving, the module uses a total of:
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 full color LED display screen unit board with two red lights in series (4) with 24 MBI5026 chips, static solid pixels (5) with 12 MBI5026 chips, dynamic 1/2 sweep solid pixels (6) with 6 MBI5026 chips , is a dynamic 1/4 sweep pixel
What do you mean by a few swipes of LED display?
In LED electronic display full-color, monochrome, two-color series of products, scanning methods are 1/16, 1/8, 1/4, 1/2, static and so on. If the difference? One of the simplest methods is to count the number of leds on the LED large screen unit board and the number of 74HC595s.
