First, the whole series form: The General Simple series link in the way of Led1-n, end-to-end connection, LED display work flow of the same current. The other is the improved method of 1.1 by the concatenation link with the bypass.
Second, the whole parallel form: one is a simple parallel form, the other is independent matching parallel form. In the simple parallel mode, the led1-n are parallel to each other, and the voltage on each LED is equal. This reliability is not high, but also to the issue of the independent matching of the parallel form, with a good driving effect, a single LED display protection intact, the failure does not affect the other work, can be matched with a large difference in the characteristics.
Three, the mixed form: by the appeal said in parallel and in series the advantages of the respective proposed synthesis. Also includes 2 kinds. One is the first string followed by the mixed way, and the other is the first and subsequent strings of the mixed way.
Four, cross array form: Cross array is mainly to improve the reliability of LED display work, reduce the failure rate raised.
