The LED display in use suddenly appears garbled due to signal problems. If it is at a severe opening ceremony, it is irreparable to lose it. How to ensure the reliability and stability of signal transmission has become an issue that engineers have to face. During the transmission of the signal in LED Screen Parts, the signal weakens with increasing distance. The choice of transmission media is particularly important.
It is very necessary to determine the brightness of the LED display.
Familiar people know that there are two ways to adjust the brightness of the full-color LED display: automatic adjustment and manual adjustment. Among them, the automatic adjustment is an intelligent brightness adjustment method that is adaptive according to the ambient brightness, and the manual adjustment method is implemented by software. So let ’s take a look at the software to adjust the brightness of the LED display screen.
The small-pitch LED display is formed by splicing a matrix of display units of the same specifications.
With the increasing display area of LED small-pitch products, projects of dozens of square meters are common. The physical resolution of LED displays often exceeds 1920 × 1200, that is, each ultra-large-scale LED display consists of several It consists of several independent display areas driven by each LED controller. For the application of the splicer, it only needs to provide several DVI output interfaces corresponding to the number of LED controller, and the entire LED screen can be spliced. In the application of small pitch LED display parts, there are several key technologies worth paying attention to.

Signal Output Synchronization
The multi-channel DVI signal output of the splicer necessarily has the problem of signal synchronization. Unsynchronized signals are output to the LED display, and the screen tearing phenomenon will appear at the splicing place shop, especially when playing high-speed moving images. How to ensure the signal output synchronization becomes the key to measure the success or failure of a splicing system.
