Many people may not know that all the components of the LED electronic display are not easy to assemble. It is as difficult as configuring a new assembled computer, even more difficult to assemble than a computer. Let us tell you more about it. One step. First of all, it is connected by a number of modules, and the module is composed of lamp beads. The steps are a ring and a ring, the ring should be careful, otherwise the LED electronic display effect will be significant. A negative impact.
Another important point of the LED display is that in the connection, once a connection is not good, the following work can not work properly. Only by knowing the thorough knowledge of this aspect, LED display will be more safe and the effect is better, because this is quite related to the brightness and power of the LED display. The high-power brightness LED of a single package is expensive. The power to enter a practical single-brightness LED display is small. Therefore, it is necessary to combine a plurality of LED display screens, on the one hand, it can meet the requirements of multiple applications such as a large range, high brightness, dynamic display, color change, and the like, and on the other hand, can meet the requirements of one driving device matched with the LED. . So what are the connection methods of the LED electronic display? Here are four ways to connect the LED display .
1, cross array: cross array is mainly to improve the reliability of LED display work, better reduce its failure.
2, series form: the LED in the simple serial mode will be connected end to end, the current flowing through the LED display will be equal.
3. Mixed form: The advantages of the cross-over and tandem combinations proposed by the appeal are combined. There are also two types. One is the hybrid mode of the first string and the back array, and the other is the hybrid mode of the first array and the last string.
4, the overall parallel form: one is a simple parallel, the other is an independent matching parallel. The LEDs in the simple parallel mode are connected in parallel at the beginning and the end, and the voltages on each LED are equal during operation. This reliability is not too high, but it also adopts an independent matching parallel form for such problems. It has a good effect of driving, and the protection of a single LED display is relatively complete. The fault does not affect other work and can be matched. Large differences and other related characteristics.
