The LED display is divided into the following parts:
The screen part of LED display screen is the most intuitive part we see when we see the large LED screen, which is generally square. The LED
display screen mainly consists of the following parts:
Led box: the internal part of LED box includes power supply part, module part and control receiving part, which is mainly used for fixationandprotection. Fixation means that all components must be fixed inside the box to facilitate the splicing of the whole screen. Generally, the box has iron box, aluminum profile, die-casting aluminum box, etc., which can effectively protect the internal components and play a good protective role
LED module / unit board: LED module is the display device of the display screen. Its display principle is that the red, green and blue LEDs constitute the pixel points, and then many pixel points constitute the display surface of the LED display screen;
LED power supply: generally, the driving voltage required for LED display screen is 5V, and the commonly used alternating current is 220V, so the commonly used power supply is 220V to 5V, etc.; wire rod and screen body wire are generally divided into three types: power wire, signal wire (network wire), cable arrangement, etc.; power wire is divided into 220V cable and 5V power wire.
2. Screen display control system
This system is composed of computer special equipment, video processor, control card system and system software.
Video processor: provide the input port of video signal, reduce the signal source of amplification input and transmit it to the sender
The input signal source of the card can be
It is camera, DVD, TV signal, game console, KTV, etc., supporting HDMI, DVI, VGA, AV, NTSC、PAL、S_ Video and other systems.
Control card system: drive and control the LED of the LED display screen to make it emit light orderly to display the picture and scan The card tracing system includes a sending card system and a receiving card system.
System software: provide special software for LED screen debugging and playing, which is used together with control card system. Computer and special equipment: computer and special equipment directly determine the function of the system, which can be linked according to the user Different types are required for different requirements of the system. 、PAL、S_ Video and other systems.
2.1. LED display system classification
LED display control system, also known as LED display controller and LED display control card. It is the core component of LED display. It is mainly responsible for receiving picture and video display information from computer serial port or DVI interface, putting it into frame memory, generating serial display data and scanning control sequence recognized by LED display in the way of partition driving
