Why should a video processor be installed in the LED display?
Recently, many customers have asked why the full-color LED display must use a video processor. It is no exaggeration to say that the quality of the video processor directly determines a display effect of the full-color LED display.
1. Motion compensation
About motion compensation for slow and fast images. Good motion compensation technology can reduce the jagged edges of moving images in full-color LED display.
2. Deinterlacing
The video signal is better to reduce the bandwidth, so the interlacing technology must be used to increase the resolution. At this time, the full-color screen needs to preprocess the interlaced signal. Great for dealing with interlacing and eliminating scribing effects during live broadcasts and filming.

3. Zoom
The full-color screen usually adopts a modular design and mosaic display, because it is the most flexible display product among all flat-panel display media. But this product also has some drawbacks, that is, the flexibility will be slightly slowed down, especially the display resolution of each engineering application is difficult to find in the standard. Therefore, the video processor is especially required to provide the zoom function.
4. Image reduction
The dot matrix resolution of general display engineering applications is below 1024*768). The video processor is required to be capable of reducing the access signals to the resolution of the corresponding terminal, and the video processing device is required to have the function of pixel-by-pixel scaling.
5. Image enlargement
Due to the rapid development of more and more engineering applications such as advertising and other businesses, the resolution of full-color LED displays is no longer limited to conventional resolutions, and some engineering applications have even reached the level of 2048 points in similar applications. , it is necessary for the video processor to have image enlargement processing technology, and the internal processing bandwidth of the video processor can reach or exceed the dot matrix area in atypical applications.
6. Noise suppression
Due to the dot matrix characteristics of full-color LED display, insignificant noise in other flat panel display media will greatly challenge the psychological tolerance of LED display audiences. The noise mainly comes from the compression noise of the video signal and the random noise of the system itself. An excellent video processor can reduce the interference of noise to the image quality itself to the greatest extent through noise suppression.
