LED display and link steps

Display which some main connection mode? The following main introduced the whole series, parallel, composite group, cross array that 4 links.

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.

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. 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.
