When you buy a led display,why do you need a led video processor? LED video processor directly affect the display effect of the LED display.
The LED video processor is a professional video processor for LED display.In simple terms, the conversion of image signals from external sources (such as Blu-ray DVDs, computers, and HD broadcast boxes) into the LED display can accept signals. Because of the quality of the video processor can directly affect led display.
Benefits of LED Video Processors
1.Suppression Noise : Due to the characteristics of LED display screens, insignificant noise in other flat panel display media will greatly challenge the psychological tolerance of LED display audiences. 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 suppress the noise and minimize the interference of the noise on the picture quality itself.
2, Zoom: LED display is usually used in modular design and splicing, because it is the most flexible display product of all flat panel display media. However, led display also has some disadvantages, that is, the flexibility will be slightly slowed, especially the display resolution of each engineering application is difficult to find in the standard. Therefore, it is particularly necessary for the video processor to provide a zoom function.
3. Image Enlargement: As more and more applications are advancing rapidly in applications such as advertising volume, the resolution of LED displays is no longer limited to conventional resolution. Some engineering applications even reach a level of 2048 points. In similar applications, the video processor is required to have image amplification processing technology, and the video processor internal processing bandwidth can reach or exceed the dot area of the atypical application.
4. Deinterlacing: Video signals are better for reducing bandwidth, so increasing resolution requires interlaced scanning. The LED display now requires pre-processing of the interlaced signal. Good to deal with interlacing technology and eliminate the line drawing effect when live broadcasting and shooting.
5, the image is reduced: the general LED display engineering application of the resolution is below 1024 * 768. It is required that the video processor has the capability of reducing each of the accessed signals to the resolution of the corresponding terminal, and the video processing apparatus is required to have a pixel-by-pixel scaling function.
6. Motion compensation: Motion compensation for slow images and fast images. Good motion compensation technology can well reduce the sawtooth phenomenon of the edges of the changing picture when playing the LED display.
