The function of the LED video processor is to convert the external image signal into a signal that can be accepted by the full color led wall.
How does the LED video processor complete the perfect display of the digital led display? Mainly include the following points:
1, The led wall zoom, the display mode of the full color led wall is point-to-point, which determines that the digital led display can only display pictures that are consistent with its physical resolution. The LED video processor can zoom the image, output the picture in any size, and complete the mapping of the entire 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 the video processor is to manage various signals when multiple signals are connected, and flexibly switch between the signals quickly.
3, The image quality is improved, because the pixel pitch of the full color led wall itself is much larger than some other flat display media. Therefore, there are strict requirements for image processing technology, especially image enhancement technology. The 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 picture quality.
4. Large led screen splicing. At present, the dot pitch of full color led video wall is getting smaller and smaller, and the overall size is becoming more and more giant. This makes the physical resolution of digital very huge. The LED video processor has a splicing function and can drive a large resolution screen, which is a very cost-effective driving method.
5. Multi-picture processing. In many special scenes, a led display needs to display multiple pictures with the same or different signals. A video processor with multi-picture processing can flexibly meet such display requirements.
In the era of high definition digital led display, video processors not only carry a lot of work such as image processing and analysis, encoding and decoding compression, but also embed a large number of intelligent analysis algorithms to analyze massive amounts of data.
Due to the influence of regional weather, outdoor full-color electronic screens are different from day to night, sunny days and rainy days. How can digital led display match the weather to display the perfect picture?
This requires the video processor to have more excellent image quality improvement capabilities, with advanced image scaling processing algorithms to ensure that the video image is zoomed to maintain the image's clarity and grayscale to the greatest extent. In addition, the video processor is also required to have rich image adjustment options and adjustment effects, and process the image brightness, contrast, and grayscale to ensure that the screen outputs a soft and clear picture.
