The assembly of LED electronic display is not easy, the connection form needs to be kept in mind

It is not easy to assemble the LED electronic display as a whole, just like configuring an assembled computer, even the LED electronic display is more complicated to assemble, and there are more steps to pay attention to. It is connected by many modules, and the module is assembled by many lamp beads. The steps are one after another, and you must be careful, otherwise the effect of the LED electronic display will be affected. .

The most important thing about the LED display is the connection. Once one connection is not good, the next link will not work properly. Only by understanding these aspects of knowledge will the led display be safer and the effect better, because this is also related to the high brightness power of the led display. The cost of a single packaged high-power high-brightness led signage display is high, and it is currently entering practical use. The power of a single high-brightness LED display is very small. Therefore, it is necessary to arrange and combine multiple LED displays according to the requirements. On the one hand, it can meet the requirements of applications such as large range, high brightness, dynamic display, and color change. On the other hand, it can meet the requirements of the driver matching the LED. match requirements.

The following mainly introduces four kinds of LED electronic display connection forms:

First, the overall series connection form: the LED1-n in the general simple series connection method is connected end to end, and the current flowing through the LED display screen is equal when it is working. The other is an improved method with a series connection mode of 1.1 with a bypass.

Second, the overall parallel form: one is a simple parallel form, and the other is an independently matched parallel form. In the simple parallel connection mode, LED1-n are connected end to end in parallel, and the voltage on each LED is equal during operation. This kind of reliability is not high, but we also strive to take the parallel form of independent matching for this problem, which has the characteristics of good driving effect, complete protection of a single led display, no influence on other work when a fault occurs, and large differences in matching.

Third, the mixed connection form: the combination of the advantages proposed by the parallel connection and series connection mentioned in the appeal also includes two types. One is the hybrid connection method of serial first and then parallel, and the other is the hybrid connection method of parallel first and then serial connection.

4. Cross-array form: The cross-array form is mainly proposed to improve the reliability of the LED display and reduce the failure rate.

To sum up, it shows that there are many ways to connect the led display screen, and each step does not allow connection errors, so this is something that engineers and technicians must understand. The above four connection methods have their own advantages and disadvantages, and the specific problems are specific. Analysis, and finally find the form that is suitable for connecting to the led display. Many engineers and technicians tend to ignore this point, which leads to various problems in the LED display screen, and finally makes customers lose confidence in the company. From this, it is found that often a small detail determines success or failure, so the LED display technology must be fine and detailed. I believe this is also the culture advocated by every enterprise company!
