The full-color LED display is a full-color display that can be more smoothly connected. The display image quality is HD / 2K / 4K / 8K. It is an indoor and outdoor full-color LED display.
Recently, many customers asked why the full-color LED display uses the video processor. It is no exaggeration to say that the quality of the video processor directly determines the display effect of the full-color LED display. If the color area appears today, it will lead the majority of users to deepen their understanding of this problem.
1. Motion compensation
Motion compensation for 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 effect of line drawing during live broadcasting and shooting.
3. Zoom
Full color LED display screen usually adopts modular design and split 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 slower. 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 reduction
The lattice resolution used in general display engineering is 1024 * 768). Video discarding is required to reduce each signal accessed to the resolution of the terminal, and video discarding equipment is required to provide point-to-point pixel amplification function.
5. Expand 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 the ordinary resolution, and the degree of reaching some engineering applications is 2048 points. In similar applications, the required video processing programs can have image amplification processing technology, The internal waste bandwidth of video processing program can reach or exceed the dot matrix area in atypical applications.
6. Noise suppression
Due to the dot matrix characteristics of LED full-color display screen, other LCD media will produce slight noise. LED display screen has the psychological patience of the audience. The noise mainly comes from the compressed noise of the video signal and the random noise of the system itself. A good video processor can suppress the noise and minimize the interference of noise on the image quality itself.
