LED electronic display screen

   Led electronic display all together is not easy, like configure an assembly of the computer, even led electronic display together more complex, more should pay attention to the steps. It is linked by lots 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. Only by understanding these aspects of knowledge, the led display will be safer, better, because it is related on high brightness led display power, single packaging of high power high brightness led's cost is high, and now into the practical application of the single power of high brightness led display is very small. So must be multiple led display are arranged together in accordance with the requirements, on the one hand, able to meet the wide range, high brightness, dynamic display, color changes, such as application requirements, on the other hand can satisfy the drive led matching with driver matching requirements. Mainly introduces four kinds of led electronic display links below form:

One, whole series form: general LED1 in a simple way of series connection - n, end to end, equals the current flows through the led display work. Another is in series connection with bypass 1.1 way of improvement.
Second, the whole parallel forms: one is simple in parallel form, the other is a parallel form of independent match. LED1 in a simple way of parallel - 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.
In the led display connection mode 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 of advantages and disadvantages of each have a specific issue concrete analysis, finally found his form is suitable for connecting the led display. Many engineering technology people tend to ignore this, lead to led display appear all sorts of problems, finally let customers lost confidence to the company. , often a small detail decides success or failure, so do the must in led display technology, do fine. I believe that is advocated by each enterprise company culture!
