Led display assembly is a complicated and cumbersome process. Each link requires engineers and technicians to have excellent professional skills to be able to fine-tune the LED display products. As people in the industry know, the LED display is made up of many modules, and the module is assembled by many lamp beads. In the assembly process of the LED display , the assembly step should be followed by a ring, and the ring should be careful, otherwise the effect of the led display will be affected. To meet the requirements of the application display led large area, high brightness, dynamic display, etc., and the LED driver drives matching matching requirements. The following mainly introduces four types of led display connections: 1 , led display screen series assembly mode: generally simple series connection mode LED1-n , end -to- end connection, the led display works the same current flowing. The other is an improved way of bypassing the series connection of 1.1 . 2 , led display screen parallel assembly method: one is a simple parallel form, the other is an independent matching parallel form. The LED1-n in the simple parallel mode is connected in parallel at the beginning and the end, and the voltages on each LED are equal when operating . This kind of reliability is not high, but it also strives to adopt an independent matching parallel form for this problem. It has a good driving effect, a single led display protection is complete, the fault does not affect other work, and the matching can be greatly different. 3 , led display cross array assembly method: cross array shape is mainly to improve the reliability of the led display work, reduce the failure rate proposed. 4 , led display mixed assembly method: the advantages of the parallel and series proposed by 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 combined first and last. The above four types of LED display assembly and connection methods have their own advantages and disadvantages, according to different applications, choose the most suitable led display connection. Many engineering and technical people often ignore this point, leading to a variety of connection failures in the LED display , which ultimately affects product quality and reduces user trust.
