Two.The basic structure of Nunin LED screen

1. Asynchronous allo:

Gabaɗaya, an haɗa shi da allon nuni (module), katin allo na allo, sauya wutar lantarki da hukumar HUB (na zaɓi) Haɗa zuwa kwamfutar ta hanyar layin tashar jiragen ruwa, yi canje-canje ga rubutun nuni, sannan kuma za ku iya cire haɗin kwamfuta don aiki.

2. Synchroscreen:

Synchronous screen system is relatively complex, the system can be large or small, generally by computer, DVI graphics card, data sending card, synchronous data receiving card, HUB board, network cable, Nunin LED screen and other components.The system always needs an online computer to work and display the images and words on the computer on the large LED screen.

3. LED Nuni koyaushe:

An independent unit consisting of an Nunin LED, as determined by the circuit and installation structure, and having display functions.To put it simply, for the convenience of assembly and display, semi-finished products from the factory are usually provided in the form of display modules, which combine multiple display modules and display drivers together.Interior screen commonly known as "unit board";Outdoor screen commonly known as "module", and then a number of modules plus chassis, fans, power supply and other structures together into a "box", mostly used for large full color screen.
