LED electronic display assembly and connection

The LED electronic display is not easy to assemble 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 modules are assembled by many lamp beads. The steps are one ring after another, and the ring must be careful, otherwise the effect of the LED electronic display will be affected. .

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

1. Overall series connection form: LED1-n in the general simple series connection method are connected end to end, and the current flowing through the LED display screen is equal when working. The other is the improved way of series connection with bypass as 1.1.

2. Overall parallel form: one is a simple parallel form, and the other is an independent matching parallel form. In the simple parallel mode, the LED1-n are connected in parallel end to end, and the voltages on each LED are equal during operation. This kind of reliability is not high, but it also adopts an independent matching parallel form to solve this problem, which has the characteristics of good driving effect, complete protection of a single LED display, no impact on other work in case of failure, and large differences in matching.

3. Mixed connection form: the advantages of parallel connection and series connection mentioned in the appeal are comprehensive. It also includes 2 kinds. One is the hybrid mode of first serial and then parallel, and the other is the hybrid mode of first parallel and then serial.

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

There are various connection methods for LED display screens. Connection errors are not allowed in each step. Therefore, it is necessary for engineers and technicians to understand. The above four connection forms each have their own advantages and disadvantages. It is suitable for connecting to the LED display form. Many engineers and technicians tend to ignore this point, which leads to various problems with LED displays, and finally makes customers lose confidence in the company.
