LED Video Processor Function Introduction
LED video processors is specially Designed for LED display.It is high-performance image processing and control devices for full color LED displays. Generally, it can change the resolution format and color space, as well as image scaling; LED video processor integrates video image processing and high-definition signal processing technology. Designing combined with the special requirements of full-color LED screen display. It can simultaneously receive and process a variety of different video graphics signals and show on full-color LED display screens. Below we will introduce the main function of video processor.
A ,Display Scaling
Led display mode is point to point, which determines the led display can only show pictures consistent with their own physical resolution size. led video processor can scale the image and output to any size that realize the whole desktop screen show in the led display.
B,Signal Conversion And Switching
Led video processor can realize conversion between many different signal format. another very important function of video processor is to manage all kinds of signals, to quickly switch between multiple signals flexible input interface such as CVBS interface (compound), VGA (simulation), DVI (digital), HDMI (number) and DP (digital), S terminal (simulation), the standard definition components (YCbCr), HD (YPbPr), SD - SDI (digital), hd-sdi (number), and so on. So led video processor can change different image signals (such as computer, TV box, DVD, camera, karaoke machines, etc.) into the signals which LED display screen can accept. It makes the LED screen display performance more clear and smooth.
C, Improve Image Quality
The pixel pitch of LED display bigger than some other flat-panel display medium, for the image processing technology, especially the image enhancement technology has strict requirements. High quality LED video processor got advanced algorithms to decorate signals. execute interlaced scanning, edge sharpening, motion compensation and so on a series of processing, enhance the detail of the image, improve image quality
D, Led screen splicing
Now,LED screen pixel pitch become smaller while display size become bigger and bigger which made the resolution huge .LED video processor with splicing function can drive screen with big resolution and save cost at the same time.
E, Multi-screen processor
Many special situations a led screen need to display multiple images of the same or different signal, a multi-screen video processor can flexibly meet this requirement.Outdoor displays for regional weather influence which requires the video processor to have superior quality promotion ability, has the advanced image scaling processing algorithm, to ensure that the video images after scaling processing, maximum keep the image resolution and gray levels.In addition, you also need to video processor has rich image adjustment options and adjustment effect, to deal with image brightness, contrast, gray level, to make sure the screen output soft and clear image.
