Shenzhen Lianchengfa Technology Co., Ltd.

Recently, many customers asked Lianchengfa editor why full-color LED displays use video processors. 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 most users to deepen their understanding of this issue.

       1. Motion compensation

        Motion compensation for slow and fast images. Good motion compensation technology can reduce the jagged edges of the moving image in the full-color LED display.

        2. Move interlaced

        The video signal can reduce the bandwidth better, so interlacing technology is also needed to improve the resolution. The full-color LED screen must now stop the pre-drop signal of the interlaced scan signal. It can handle the interlaced scanning technology well, eliminating the line effect during live broadcast and shooting.

        3. Move fast

        The full-color LED display usually adopts modular design and split-screen display. Because it is the most sensitive display product among all flat display media. However, this product also has shortcomings, the sensitivity may be slightly slower. In particular, the display resolutions for various engineering applications are difficult to find in the specifications. Therefore, the video processor is particularly required to provide the zoom function.

        4. Image restoration

        The lattice resolution used in general display projects is 1024*768. Video discarding needs to reduce each incoming signal to the resolution of the terminal, and video discarding equipment needs to provide point-to-point pixel amplification.

        5. Expand the image

        Nowadays, with the rapid development of more and more engineering applications, advertising and other businesses, the resolution of full-color LED displays is no longer limited to ordinary resolutions, and some engineering applications reach 2048 points. In similar applications, the required video processing program can have image magnification processing technology, and the internal waste bandwidth of the 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 displays, other LCD media will produce slight noise. The LED display has the psychological patience of the audience. The noise mainly comes from the compression noise of the video signal and the random noise of the system itself. A good video processor can suppress noise and minimize the interference of noise on the image quality itself.
