How to identify the led display scan mode 1/2, 1/4, 1/8, 1/16
In a certain display area, the number of lines lit at the same time the ratio of the number of rows in the region, said scanning; indoor single color is generally 1/16 scan, indoor full color is generally 1/8 scan, outdoor single color is generally 1/4 scan, outdoor full color is generally static scanning.
Currently on the market led display drive mode has two kinds of static scanning and dynamic scanning, static scanning is divided into static real pixels and static virtual, dynamic scanning is also divided into dynamic real and dynamic virtual; drive devices commonly used domestic HC595, Taiwan MBI5026 , The Japanese Toshiba TB62726, generally 1/2 sweep, 1/4 sweep, 1/8 sweep, 1/16 sweep.
A common full-color module pixel 16 * 8 (2R1G1B), if the MBI5026 driver, the module is used in total:16 * 8 * (2 + 1 + 1) = 512, the MBI 5026 is a 16-bit chip, and 512/16 = 32
(1) If using 32 MBI5026 chips, it is static virtual
(2) if the chip with 16 MBI 5026, is dynamic 1/2 sweep virtual
(3) if the chip with 8 MBI5026, is dynamic 1/4 sweep virtual
If the two red light string on the board
(4) with 24 MBI5026 chip, is a static real pixels
(5) with 12 MBI5026 chip, is dynamic 1/2 scan pixels
(6) with 6 MBI5026 chip, is dynamic 1/4 scan real pixels
In the LED unit board, scanning mode 1/16, 1/8, 1/4, 1/2, static. If the distinction? One of the most simple way is to count the number of LED modules and the number of 74HC595.
Calculation method: the number of LEDs divided by the number of 74HC595 divided by 8 = a fraction of the scan
Real pixels and virtual is the corresponding: in simple terms, the real pixel screen means the composition of the three red, green and blue LED tubes in each of the final tube only involved in the imaging of a pixel to use, in order to obtain sufficient brightness .
The virtual pixel is a software algorithm to control each color LED tube ultimately involved in the imaging of multiple adjacent pixels, so that with less lamp to achieve greater resolution, can display resolution increased by four times.
IC to see the number of individual modules, the static drive ic control 16 points,
If a single module is 32 * 16 points, which only 8 ic, then 32 * 16/16/8 = 4, or 1/4 scan;
Personal point of view, for reference only, please correct me!
