Analysis of the main functional modules of LED display

 

Through multimedia video control technology and VGA synchronization technology, Shenzhen LED display can easily introduce various forms of video information sources into the computer network system, such as radio and television and satellite TV signals, camera video signals, VCD video signals of video recorders, computer animation information, etc., so as to achieve the following functions:

Shenzhen LED display supports VGA display, displaying various information, graphics, and images of the computer. Support a variety of input methods; Support PAL, NTSC and other systems. Real-time display of color video images for real-time transmission. Relay of radio and television, satellite and cable television signals. Real-time playback of video signals such as TVs, camcorders, video discs (VCR, VCD, DVD, LD). It has the function of playing pictures and text in different proportions at the same time.

 

Graphic display function: with editing, zooming, flowing, animation and other functions. Display a variety of computer information, graphics, images, as well as 2D and 3D computer animations and overlay text. The playback system is equipped with multimedia software, which can flexibly input and play various information. There are a variety of Chinese fonts and fonts to choose from, and you can also input characters such as English, Spanish, French, German, Greek, Russian, Japanese, etc. There are multiple playback modes, such as: single-line/multi-line PAN, single-line/multi-line/down, left/right pull, up/down, rotation, stepless zoom, etc. Edit, play and publish announcements, announcements, announcements and news instantly, with a variety of font options. Equipped with standard network interface, it can be connected to other standard networks (information query system, municipal publicity network system, etc.). Collect and play real-time data from each database to achieve remote network control. You can access the Internet through the network system, with a sound interface, can access audio equipment, to achieve audio and image synchronization.

 

The LED display screen controller controls the display effect of the corresponding display. It can automatically run the program in a continuous loop to obtain relevant display data according to the given program service, or it can manually intervene to produce a display effect on the screen. The pixels on the screen and the pixel display in the corresponding area on the screen controller are mapped one-to-one, and are directly mapped. The screen controller can manually adjust the brightness of the display and select the grayscale nonlinear correction data that is appropriate for the current environment. The screen controller can also automatically adjust the display brightness through the network system and select different grayscale nonlinear correction data according to the ambient brightness.

 

The screen control machine can adjust the contrast and chromaticity of the image display. The screen controller transmits the information to the video processing and control unit for video processing.
