What is the role of video processor to full color LED display?

Recently, many customers have asked why full color LED display screen must use video processor. It is not exaggeration that the advantages and disadvantages of video processor directly determine a display effect of full-color LED display. Today, mini photoelectric brings the vast number of users to understand this problem in depth:
1. Motion compensation
Motion compensation for slow and fast images. Good motion compensation technology can reduce the edge serration of motion image when full color LED is displayed.
2. De interlaced scan
In order to reduce the bandwidth of video signal better, interlaced scanning technology is necessary to improve the resolution. The full color screen needs to preprocess the interlaced signal. Good to deal with interlaced scanning technology and eliminate the line tracing effect in live broadcast and shooting.
3. Zoom
Full color screen usually adopts modular design and splicing display, because it is the most flexible display product in all flat panel display media. But there are some disadvantages in this product, that is, flexibility will be slightly slowed down, especially the display resolution of each engineering application is difficult to find in the standard. So it is necessary for video processor to provide zoom function.
4. Image reduction
The lattice resolution of general display engineering application is under 1024 * 768). The video processor is required to reduce the access signals to the resolution of the corresponding terminal, and the video processing equipment is required to have the function of pixel by pixel scaling.
5. Image magnification
With the rapid development of more and more engineering application advertising and other businesses, the resolution of full-color LED display is no longer limited to the conventional resolution. Some engineering applications even reach the level of 2048 in similar applications, so video processor is required to have image amplification processing technology, And the bandwidth of the video processor can reach or exceed the lattice area in the atypical applications.
6. Noise suppression
Because of the dot matrix characteristics of full color LED display, the negligible noise in other flat panel display media will greatly challenge the psychological tolerance of the LED display audience. The noise mainly comes from the compression noise of video signal and the random noise of the system itself. Excellent video processor can reduce the noise interference to the image quality to the greatest extent through noise suppression.
