Recently, many customers have asked why full-color LED displays use video processors. It is no exaggeration to say that the quality of video processor directly determines the display effect of full-color LED display screen. If the color area appears today, it will guide most users to deepen their understanding of this problem.
1. Motion compensation
Motion compensation of slow image and fast image. Good motion compensation technology can reduce the sawtooth of moving image edge in full-color LED display.
2. Mobile interlacing
Video signal can better reduce bandwidth, so interlacing technology is also needed to improve resolution. The full-color screen must now stop the pre discarded signal of the interleaved scan signal. It can deal with interlaced scanning technology well and eliminate the scribing effect in the process of live broadcast and shooting.
3. Fast moving
Full color LED display screen usually adopts modular design and split screen display. Because it is the most sensitive display product in all flat display media. However, the product also has disadvantages, and the sensitivity may be slightly slow. In particular, the display resolution of various engineering applications is difficult to find in the specification. Therefore, it is particularly necessary for the video processor to provide amplification function.
4. Image restoration
The lattice resolution used in general display engineering is 1024 * 768). Video discarding needs to reduce each signal accessed to the resolution of the terminal, and the video discarding device needs to provide point-to-point pixel amplification function.
5. Expand the image
Nowadays, with the leap of more and more engineering applications, advertising and other businesses, the resolution of full-color LED display is no longer limited to ordinary resolution, and some engineering applications have reached 2048 points. In similar applications, the required video processing program can have image amplification processing technology, and the internal waste bandwidth of the video processing program can reach or exceed the dot matrix area in atypical applications.
