Display on the control card types , production control card companies , such as the Qing, Yang Bang , Yi-wide , Kim Han , etc. is simply divided into : full-color synchronous card asynchronous offline card full-color video off-line card With nearly two years the rapid development of LED display , LED control card market becomes more extensive , especially in 2009 just new from the U disk LED control card is used up , available serial port connected to a computer , can also be U disk transmission of information , the provincial PC -free routing, support for analog clock , water frame , U disk LED control card can be saved by computer , the provincial wiring .

1. In the outdoor production, the glue is applied after the glue is applied, and then the kit is applied.2, the outdoor needs to be fully waterproof, semi-outdoor does not need waterproof.3, the outdoor brightness is higher, the brightness of the semi-outdoor can generally4, the outdoor is made of fully enclosed box, the protection level is high; semi-outdoor is mostly made of direct aluminum or simple box, the protection level is low

  Today, LED displays have become a part of people's lives.Streets and alleys, square stations, you can see a variety of LED electronic displays of various sizes and shapes.It is a systematic project integrating optical, structural mechanics, electronics and computer science.According to statistics, 90% of LED displays have large or small faults.To this end, we summarize the main reasons for these failures,I believe that with these, we can control the generation of faults from the source and improve the quality of the display.
