LED display scan mode setting method
on the market of LED display driver way is divided into two kinds of static scan and dynamic scan, and can be divided into static static scan pixels and static virtual, dynamic scanning can also be divided into dynamic realities and dynamic virtual; MBI5026 drive devices commonly used in domestic HC595 are needed, Taiwan, Japan's Toshiba TB62726, generally has a 1/2, 1/4, 1/8, 1/16.
and the commonly used full-color module is 16 * 8 pixels ( 2 r1g1b) , if use MBI5026 drive, module is used: a total of 16 * 8 * ( 2 + 1 + 1) = 512, MBI5026 as 16 chip, 512/16 = 32
( 1) If use 32 MBI5026 chip, is static virtual
( 2) If use 16 MBI5026 chip, it is 1/2 and dynamic virtual
( 3) If use eight MBI5026 chip, is a dynamic 1/4 sweep virtual panel if two red lights together
( 4) With 24 MBI5026 chip, is static pixel
( 5) With 12 MBI5026 chip, is a dynamic 1/2 sweep real pixel
( 6) With six MBI5026 chip, is a dynamic sweep a quarter real pixel
that's technical personnel to introduce the full color LED display of photoelectric scanning mode setting method, on the LED unit board, scanning mode is divided into 1/16, 1/8, 1/4, 1/2, the static. How to distinguish? Has one of the most simple way is to count the number of the LED unit board and the number of 74 hc595 are needed.
