The full-color LED display is a large LED screen spliced by multiple LED modules, and the display module is assembled from many LED lamp beads. Whether the effect of the LED display is good or not has a lot to do with the assembly of the LED display. The key to the assembly of the display screen is the connection method. If the connection is not good, it will affect the picture quality of the LED display screen, and even cause the display screen to fail to operate normally. So what are the connection methods of the full-color LED display? do you know? Let the LED display manufacturer LCF (www.lcf-led.com) share this knowledge with you.  

 

1. Overall series connection mode: LED1-n in the general simple series connection mode 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.the overall parallel mode: one is a simple parallel form, 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 good driving effect, complete protection of a single full-color LED display, does not affect the work of other screens in case of failure, and can be matched with larger differences, etc.

 

3. Mixed connection method: The advantages of parallel connection and series connection mentioned in the appeal are comprehensive. It also includes 2 types. 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 method: The cross array form is mainly proposed to improve the reliability of the full-color LED display and reduce the failure rate.

 

The above are the four connection methods of full-color LED display that LED display manufacturer Liancheng sent to you to share and summarize. Which one to choose depends on the actual situation of the project.
