LED display all assembled and its not easy, as if the configuration of an assembled computer, even LED display assembly is more complex, more to pay attention to the steps. It is connected by many blocks of module, and the module is assembled by many lamp beads, which the steps are a ring after a ring, ring to be careful, otherwise led display effect will have an impact. And led display is important in the connection, once the connection is not good, the next step is not good.
Therefore, today we will discuss what are the ways to connect the led display? Only understand these aspects of knowledge, led display will be more secure, better effect, because it is also related to the led display high brightness power, a single package of high power high brightness LED's cost is high, and at present into the utility of a single high brightness led display power is very small. Therefore must be more than one led display screen in accordance with the requirements of the arrangement and combination, on the one hand, to meet the larger range, higher brightness, dynamic display, color variation and other application requirements, on the other hand, to meet the LED with the matching driver drive matching requirements.
The following
LED Cotroller Store mainly introduces four kinds of led display connection form:
First, the overall series connection form: the general simple series connection link way in the LED1-n, first and last connected, led display work when the current flowing through the same. Another is the series connection with bypass for 1.1 improvement.
Second, the overall parallel form: one is a simple parallel form, another is an independent matching parallel form. Simple parallel mode in the LED1-n first and last parallel connection, work on each LED to withstand the voltage is equal. This reliability is not high, but also contend with this problem to take the parallel form of independent matching, has a good driving effect, a single led display protection integrity, failure does not affect the other work, can be matched with a large difference and so on.
Third, mixed form: by the above mentioned parallel and series connection of the advantages of each proposed synthesis. Also includes 2 kinds. One is the first series after the parallel mixed mode, the other is the first parallel after the series of mixed mode.
Fourth, cross array form: cross array form is mainly to improve the reliability of led display work, reduce the failure rate proposed.
