Video processor on the role of full-color LED display

Recently, many customers asked why the full-color LED display video processor has to use this issue, it is no exaggeration to say that the merits of the video processor directly determines the full color LED display a display. Light Color today with the majority of users to in-depth understanding of this problem:
 
1, motion compensation
Motion compensation for slow and fast images. Good motion compensation technology can be very good to reduce the full-color LED display jagged edges of moving images.
 
2, to interlacing
Video signals to better reduce the bandwidth, so to improve the resolution must also use interlacing technology. Full-color screen at this time need to interlaced signal pre-processing signal. It works well with interlacing techniques and eliminates the tracing effects of live broadcasts and shots.
3, zoom
The full color screen is generally used modular design and stitching display, because it is one of the most flexible display products of all flat panel display media. However, this product has some drawbacks, that is, the flexibility will be slightly slowed down, especially the display resolution of each engineering application is hard to find in the standard. So special need video processor to provide zooming function.
 
4, the image is reduced
General screen engineering applications have a dot matrix resolution of 1024 * 768). The video processor is required to reduce each signal accessed to the resolution of the corresponding terminal and require the video processing device to have a pixel-by-pixel zoom function.
 
5, the image is enlarged
As more and more engineering applications such as advertising volume by leaps and bounds, full-color LED display resolution is no longer confined to conventional resolution or less, some engineering applications even reached the level of 2048 points in such applications , You need the video processor can have image amplification processing technology, as well as video processor internal processing bandwidth can reach or exceed the dot matrix area in atypical applications.
 
6, noise suppression
Due to the dot matrix nature of the full-color LED display, the insignificant noise in other flat panel display media will greatly challenge the LED display audience's psychological endurance. The noise mainly comes from the compression noise of the video signal and the random noise of the system itself. The excellent video processor can reduce the interference of the noise to the picture quality itself through noise suppression.
