LED video processor is also called picture processor, image converter, video controller, image processor, video format converter, independent video source, etc.
LED video processor is the witness and key equipment of the birth, growth and maturity of LED full-color display. The advantages and disadvantages of LED video processor directly affect the display effect of LED display screen. The binding use of LED video processor and display screen greatly facilitates the extensive application of end users and improves the depth of LED display.
Full color LED multi screen video image processor is a high-performance image processing and control equipment for full-color LED launched by national high-tech enterprises. The device integrates years of rich experience in video image processing, high-definition signal processing and display, adopts patented hardware design, combined with the special requirements of full-color LED display, and can receive and process a variety of different video graphics signals at the same time, and display on the full-color LED.
Main function editing
LED video processor is a high-performance image processing and control equipment for full-color LED display. Based on the video image processing and high-definition signal processing technology for many years, the patented hardware design and the special requirements of full-color LED screen display are adopted. It can receive and process a variety of different video graphics signals at the same time and display them on the full-color LED.
In short, LED video processor is a special LED video processor. The task it needs to complete is to transform the image signal from the outside (such as Blu ray DVD, computer, HD player box, etc.) into the signal that the LED display can accept, and optimize the video image to make the LED screen display clearer and smoother.
1、 Zoom
The display mode of LED display screen is point-to-point, which determines that led display screen can only display the same picture with its own physical resolution. LED video processor can zoom the image, output the picture in any size, and map the whole desktop to the LED screen.
2、 Signal conversion and switching
Video processing equipment can complete the format conversion between many signals. Another important function of video processor is to manage all kinds of signals when there are multi-channel signals, and switch between them flexibly.
3、 Image quality improvement
Because the pixel spacing of LED display screen is much larger than other flat panel display media, there are strict requirements for image processing technology, especially for image enhancement technology. High quality LED video processor can use advanced algorithms to modify the signal with poor image quality, perform a series of processing such as de interlacing, edge sharpening, motion compensation, etc., to enhance the details of the image and improve the image quality.
4、 Large screen splicing
At present, the point spacing of LED display is becoming smaller and smaller, and the overall size is becoming more and more huge, which makes the physical resolution of LED screen become very large. LED video processor has splicing function and can drive large resolution screen, which is a very cost-effective driving mode.
5、 Multi screen processing
In many special scenes, a display screen needs to display multiple pictures of the same or different signals. The video processor with multi image processing function can flexibly meet such display requirements.
The outdoor display screen is affected by regional weather, which requires the video processor to have better image quality improvement ability and advanced image scaling processing algorithm to ensure that the video image after zooming can maintain the image clarity and gray level to the greatest extent. In addition, the video processor is also required to have rich image adjustment options and adjustment effects, and process the brightness, contrast and gray of the image to ensure the soft and clear screen output.

Role editor
Multi picture full color LED splicing image processor can support up to 16 transmitting cards with different resolutions at the same time, and the single machine can support up to 30720 * 1080 LED dot matrix. The cascade of multiple machines can realize the real-time dynamic display of LED lattice with infinite amplitude.
The transmitting card can be arbitrarily configured for LED lattice stacking, and the gray level can be freely selected. The output lattice of single LED transmitting card can be set arbitrarily.
