LED large screen assembly is a complex and cumbersome process, each link requires engineers and technicians to have excellent professional skills, in order to be able to make LED large screen products refined and meticulous. People in the industry know that the large LED screen is made up of many modules, and the modules are assembled from many lamp beads. Can the LED large screen be assembled by myself?
During the assembly process of the LED large screen, the assembly steps are one after the other, and the loop must be careful, otherwise the effect of the large LED screen will be affected. In order to meet the requirements of LED large screen, large area, high brightness, dynamic display and other applications, as well as the drive matching requirements of LED drivers. The following mainly introduces four types of LED large screen connection forms:
1. The LED large screen is assembled in series with the whole screen: 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 it is working. The other is the improved way of series connection with bypass as 1.1.
2. The parallel assembly method of the LED large screen and the whole screen: one is a simple parallel form, and the other is an independent matching parallel form. The LED1-n in the simple parallel mode 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 large screen, no impact on other work in case of failure, and large differences in matching.
3. LED large screen cross array assembly method: The cross array shape is mainly proposed to improve the reliability of the LED large screen operation and reduce the failure rate.
4. LED large screen mixed assembly method: the advantages of parallel and series 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.
The above four LED large screen assembly and connection methods have their own advantages and disadvantages, and the most suitable LED large screen connection method can be selected according to different applications. Many engineers and technicians tend to ignore this point, which leads to various connection failures on large LED screens, which ultimately affects product quality and reduces user trust. It can be seen that the assembly of the LED large screen, the details determine the success or failure!
