Several key technologies of small-pitch LED screen video processor
As the display area of ​​LED small-pitch products becomes larger and larger, projects of several tens of square meters are not uncommon, and the physical resolution of LED displays often exceeds 1920×1200, that is, each ultra-large LED display is composed of several It is composed of several independent display areas driven by each LED controller. For the application of the splicer, it is only necessary to provide several DVI output interfaces corresponding to the number of LED controllers, and to splicing and display the entire LED screen. In the application of splicer in small-pitch LED display, there are several key technologies worthy of attention.

Signal output synchronization

The multi-channel DVI signal output of the video processor must have the problem of signal synchronization. When the asynchronous signal is output to the LED display, screen tearing will occur at the splicing point, especially when playing high-speed moving images. How to ensure the output synchronization of the signal becomes the key to measure the success or failure of a splicing system.

Graphics Processing Algorithms

We know that the point-to-point image display effect is the best. If the image is reduced and processed, if only ordinary graphics processing technology or general FPGA graphics processing algorithm is used, the edges of the image will appear jagged, and even there will be pixel missing. The brightness will also decrease. However, high-end image processing chips or FPGA systems using complex graphics processing algorithms will maximize the display effect of the reduced image. Therefore, a good graphics processing algorithm is a key technology for a splicer applied to a small-pitch LED display.

Non-standard resolution output

The small-pitch LED display is composed of a matrix of display units of the same specification. The size and physical resolution of each display unit are fixed, but the entire large screen spliced ​​together is often not a standard physical resolution. For example, the resolution of the display unit is 128×96, which can only be spelled 1920×1152, but cannot be spelled 1920×1080. In a super large-scale splicing system, the LED display area driven by each LED controller may not be of standard resolution. At this time, it is critical that the output of the splicer has a non-standard resolution, which can help us quickly find a suitable The splicing method can reasonably allocate resources and effectively save the number of LED controllers and transmission equipment used.
