LED video processor is also called screen processor, image converter, video controller, image processor screen converter, video format converter independent video source, etc.
The LED video processor is the screen processor. The full-color LED display is the witness and key equipment for the birth, growth and maturity of the LED full-color display. The quality of the LED video processor directly affects the display effect of the LED display. The combination of the LED video processor and the display screen greatly facilitates the wide application of end users and improves the depth of use of the LED display screen.

The full-color LED multi-screen video image processor is a high-performance image processing and control device for full-color LED launched by a national high-tech enterprise. The equipment integrates many years of rich experience in video image processing, high-definition signal processing and display, etc., adopts patented hardware design, combined with the special requirements of the full-color LED screen display, and can simultaneously receive and process a variety of different video graphics signals , And displayed on the full-color LED display.
So how does the LED video processor work, do you know? Let me introduce you to the editor below.
LED display
1. Resolution specification conversion: Generally speaking, the signal resolution provided by the image signal source (such as Blu-ray DVD, computer, high-definition playback box, etc.) has a fixed specification (refer to VESA, ITU, SMPTE and other standards), and LED display The modular splicing display of the screen makes its resolution almost any value. The video processor converts various signal resolutions into the actual physical display resolution of the LED display.
2. Color space conversion: The color gamut of the LED display is very wide, and the color space of most image signals is relatively small (such as NTSC). In order for the LED display to have an excellent image display effect, color space conversion must be carried out.
3. Increased bit depth: The gray level of the current LED display has been increased to 16 bits and 17 bits, but the input signal source is mostly only 8 bits. Therefore, following the advent of the era of high-definition display, the application of 10-bit or even 12-bit processing technology in video processors has become a general trend.

4. Scaling: During the conversion of the resolution specification, the image needs to be scaled. Whether the resolution is increased or decreased, the complete image can be displayed on the screen.
5. Image processing and enhancement technology: Digital image processing technology has developed from the 1920s to the present, and a large number of patented technologies have emerged. For example, DCDi, ACC2, ACM3D and other Emmy award-winning Faroudja Laboratory's series of patented technologies. These technologies have undoubtedly greatly improved the visual effects of images.
