Concept of LED Control System
LED display control system (LED Display Control System), also known as LED display controller, LED display control card. It is composed of the core components of the LED display, is mainly responsible for receiving from the computer serial port or DVI interface, the screen and video display information, into the frame memory, according to the district drive to generate LED display can identify the serial display data and Scan control timing.
System Composition
LED graphic display system consists of software control system, wireless transmission system, equipment, the main controller, LED display lattice, power and other components.
System work process
The main task of the software control system is the graphic editing, the font extraction and the preservation, the image preview and the document transmission. The wireless transmission system mainly completes the document information transmitted from the PC to the LED display. The main task of the LED dot matrix in the hardware control system is through the current Control to complete the information display, through the single-chip scanning drive mode control on the LED dot matrix row drive, to achieve the device driver and finally achieve the received graphics display.
1, the signal source can be cameras, laptops, desktop computers, DVD and other video output devices;
2, the signal through the video processor, converted into DVI signal, through the DVI cable to connect to the sending card;
3, the control room distance from the display screen is greater than 100M of the case, the use of fiber conversion card, the use of fiber optic cable communication;
4, each display box has a reception, the use of cable between the receiving card to connect communications;
5, because the display is T-shaped appearance, the system transmission from the bottom up the way of communication;
6, the display can play a variety of content, you can switch the input source;
7, the use of the camera can be real-time video signal broadcast to the display above, you can also link the digital set-top box, play TV content;
8, you can use the playback software, play on the computer pre-processed video image information.
System Advantages
Compared with the traditional display device, this huge demand for the future so that large-screen display technology has become the focus of attention:
(1) LED display color rich, display different ways (graphics, text, three-dimensional, two-dimensional animation, TV screen, etc.), high brightness, long life, information communication facilities epoch-making products;
(2) LED display is a set of optoelectronic technology, microelectronics technology, computer technology, information processing technology in one of the high-tech products can be used to display text, computer screen synchronization graphics. It is its large screen, super vision, flexible display of the advantages of living alone, is the current use of a wide range of international display system;
(3) LED display widely used, financial securities, bank interest rates, commercial advertising, cultural and entertainment, etc., have great social benefits and rich economic benefits.
