Many people may not know that it is not easy to assemble all the components of an LED electronic display. It is as difficult as configuring a new assembled computer, and even more difficult than assembling a computer. Here, Lianchengfa tells you that we have more to go. Pay attention to one of its steps. First of all, it is connected by many modules, and the module is composed of lamp beads. The steps in this are ring by ring, and the ring should be carefully, otherwise the LED electronic display effect will have a significant effect. A negative impact.

Another important aspect of the LED display is the connection. Once a connection is not good, the following work will not work properly. Only by thoroughly understanding this knowledge, LED display screens will be safer and more effective, because this is quite related to the brightness power of LED display screens. The cost of a single package of high-power brightness LEDs is high, and The power of a single-brightness LED display that enters the practical application is very small. Therefore, it is necessary to arrange and combine multiple LED display screens. On the one hand, it can meet the requirements of multiple applications such as a larger range, higher brightness, dynamic display, and color change, and on the other hand, it can meet the requirements of a driving device that matches the LED. . So what are the connection methods for LED electronic displays? Lianchengfa summarized four connection forms of LED display screens for everyone here.

 

1. Cross-array: The main purpose of the cross-array is to better improve the reliability of the LED display and reduce the occurrence of one of its failures.

2. Series form: Generally, the LEDs in the simple series form will be connected end to end, and the current flowing through the LED display screen will be more equal when it is working.

3, the form of mixed connection: the combination of advantages proposed by the crossover and tandem of the appeal theory. There are also 2 types. One is the mixed-connection method of stringing first and then the other is the mixed-connection method of stringing first and then stringing.

4. Overall parallel connection: one is simple parallel connection, and the other is independent matching parallel connection. In the simple parallel mode, the LEDs are connected in parallel end to end, and each LED bears the same voltage during operation. This kind of reliability will not be too high, but an independent matching parallel form is also adopted for this type of problem. It has a good driving effect, a single LED display screen is relatively complete, and it does not affect other work in the event of a failure. It can be matched with Relative characteristics such as large differences.

 

In summary, the above illustrates the diversity of LED display connection methods, and each step does not allow connection errors. Therefore, it is necessary for engineering and technical personnel to understand. Each of the above connection types has each The advantages and disadvantages, the specific analysis of the specific problems, and finally find the form that suits you to connect to the LED display. Many engineering and technical people often ignore this point, which leads to various problems with LED displays, and ultimately makes customers lose confidence in the company. From this lesson, it can be seen that a small detail determines success or failure. Therefore, in the LED display technology, Lianchengfa requires that the majority of LED display manufacturers and enterprises must be precise and detailed. Lianchengfa believes that as long as each company does its own every step , The majority of customers will certainly continue.
