 [News] LED large screen video display system architecture manufacturers 
 [Tip] video host controller core, with a display control unit displays, scan board 
 LED large screen video display system manufacturers architecture: includes three parts. 

 1. Video source capture and transmission (video master) 

 (1) multimedia video cards (video capture, send Monitor to monitor, allocate the output in line with manufacturers of LED large screen display of the digital signal). Such as the east star of multimedia video card can achieve these functions, simple structure. But this drawback is not conducive to long-distance transmission. 

 (2) First frame controller directly from the PC's DVI interface to obtain the frame image, and then packed with fiber optic or Gigabit Ethernet transmission to the screen controller, display controller to transform data into line with manufacturers of LED large screen display of digital signal is sent to scan board. Can achieve long-distance transmission, but the structure is more complex. 

 2. Display (with display control unit) 

 He sent the board receive the scan data. Led display array is generally positive, on the back of the control unit is a shift register with latch function of constant current driver ic, ic with some gray-scale control 

 3. Scan board 

 The role of connecting the one hand, it receives the master controller of the video signal, the other belonging to the class data to their own individual display control unit, but also do not belong to the same level of data down a cascade of scanning plate transmission. It is responsible for coordinating the digital video signal and the large LED screen manufacturers display data in time, space, progressive and other aspects of difference, so a high degree of difficulty and complexity.
