LED electronic display assembly connection form

The assembly of the led electronic display is not easy, just like configuring an assembled computer, and even the assembly of the led electronic display is more complicated and more steps to pay attention to. It is connected by many modules, and the modules are assembled by many lamp beads. The steps are one by one, and the rings must be careful, otherwise the effect of the led electronic display will be affected. . The important thing about the led display is in connection, once one connection is not good, the next link will not work properly. Only with the knowledge of these aspects, the LED display will be safer and better, because it is also related to the high brightness power of the LED display. The cost of a single package of high-power high-brightness LED is high, and it is currently in practical use. The power of a single high-brightness LED display is very small. Therefore, it is necessary to arrange and combine multiple LED display screens according to the requirements. On the one hand, it can meet the requirements of applications such as larger range, higher brightness, dynamic display, and color change. On the other hand, it can meet the drive of the driver matched with the LED. Match requirements. The following mainly introduces four LED electronic display connection forms:

1. The overall series connection: LED1-n in the simple connection mode is connected end to end. The current flowing through the LED display screen is equal. The other is the improved way with a series connection with bypass of 1.1.

Second, the overall parallel form: one is a simple parallel form, the other is an independently matched parallel form. In the simple parallel mode, the LED1-n are connected in parallel from end to end, and the voltage on each LED is equal during operation. This reliability is not high, but it also strives to adopt an independent matching parallel form for this problem, which has the characteristics of good driving effect, complete protection of a single LED display, no other work is affected during failure, and it can be matched with large differences.

Third, the form of mixed connection: The advantages of the parallel and series mentioned by the appeal are comprehensive. Also includes 2 types. One is a serial-to-parallel hybrid, and the other is a parallel-to-parallel hybrid.

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

In summary, there are a variety of connection methods for led display screens. Connection errors are not allowed in each step, so this must be understood by engineering and technical personnel. The above four connection forms have their own advantages and disadvantages. The specific problems are specific Analysis, and finally found that he is suitable for connecting led display form. Many engineering and technical people often ignore this, leading to various problems with LED displays, which ultimately makes customers lose confidence in the company. From this, it is often found that a small detail determines success or failure, so in the LED display technology must be refined and fine. I believe this is also the culture advocated by each enterprise!
