It is not easy to assemble LED electronic displays. It’s like configuring a computer to assemble. Even the assembly of LED electronic displays is more complicated and requires more steps. It is connected by many modules and the module is assembled by many lamp beads. The connecting ring is interlocked, otherwise the LED electronic display effect will be affected. LED electronic displays are important in terms of connectivity. Once the connection is not good, the next link will not work.
So today, what is the way to connect LED electronic display connections? Only by understanding these aspects of knowledge, LED electronic display will be safer and better, because it is also related to the high-brightness power supply of LED electronic display, and high-power high-brightness LED is higher than high-brightness LED in single package. The cost is high. However, the power of a high-power high-brightness LED of a single package currently used is small. Therefore, it is necessary to arrange a plurality of LED electronic display screens according to needs, on the one hand, it can meet the requirements of a wide range, high brightness, dynamic display, color change, etc., and on the other hand, can meet the driver matching requirements of the driver matched with the led.
The following mainly introduces the four LED electronic display electronic display connection forms:
First, the overall parallel form
One is a simple parallel form and the other is an independently matched parallel form. LED1-n in the simple parallel mode is connected in parallel at the beginning and at the end, and the voltage on the electronic display of each LED is equal during operation. This reliability is not high, but it also uses an independent matching parallel form to solve this problem. It has a good driving effect, complete protection of a single LED electronic display, does not affect other work during the fault, and can match large differences.
Second, the overall serial form
Typically, LED1-n in series connection mode is connected end to end, and the current flowing through the LED electronic display is equal.
Third, the cross array form
The cross array shape is mainly proposed to improve the reliability of the LED electronic display and reduce the failure rate.
Fourth, the mixed form
The advantages presented by the parallel and series in the appeal are combined. There are also two types. One is a hybrid mode in which the strings are first combined, and the other is a hybrid mode in which the strings are first and then followed by a string.
In short, the connection mode of the LED display is varied, and connection errors are not allowed in every step. Therefore, engineers and technicians must understand this. Each of the above four connection forms has advantages and disadvantages. Analyze and find a way to connect to the LED display. Many engineers and technicians often ignore this, causing various problems in the LED display, and ultimately let customers lose confidence in the company. Usually a small detail determines success or failure, so LED display technology must be improved. I believe this is also the culture advocated by every company!
