LED display is linked by a lot of pieces of module, the module is made up of many lamp bead assembly, this step is a ring then a ring, inside have to be careful, otherwise the LED electronic display effect is produced. The LED display is important in terms of connection, once a connection is not good, the next link can't work normally. Below mainly introduces four kinds of LED electronic display connection forms: one, the whole series forms: general simple serial links LED1 - in the way N, end to end, equals the current flows through the LED display work. Another is in series connection with bypass to 1. One way of improvement. Second, the whole parallel forms: one is simple in parallel form, the other is a parallel form of independent match. Simple LED1 - in parallel way N fore and aft in parallel, work equals the withstand voltage on each LED. The reliability is not high, but also for parallel form adopted independent match about this problem, a single LED display driver with good results, protection, complete failure does not affect other work, can match has many characteristics, such as bigger difference. Three, hybrid forms: by telling on each of the parallel and series of the advantages of the proposed integrated. Also includes 2 kinds. One is after the first string and hybrid mode, the other is a first and after a string of hybrid mode. Four, cross array form: cross array shape is mainly for the sake of improving the working reliability of the LED display, reduce the failure rate. LED display connections are diverse, each step does not allow a connection error, so that engineering technical personnel is a must to know, the above four kinds of connection form the advantages and disadvantages of each have a, a specific analysis, finally found his form is suitable for connecting the LED display.
