Led display assembly is a complex and cumbersome process, each link requires engineering and technical personnel have excellent professional skills, can be led display products do fine, fine. Insiders are aware, led display is made of a lot of modules from the stitch, and the module is assembled by a number of beads. In the led display assembly process, the assembly step followed by a ring, ring should be careful, otherwise led display effect will have an impact. To meet the led display large area, high brightness, dynamic display applications such as requirements, and supporting the drive with the LED drive matching requirements. The following describes the four led display connection form:
1, led display the entire screen series Assembly: generally simple series connection in the way LED1-n, end to end, led display work flow current equal. The other is the way with the bypass connection 1.1 for the improvement of the way.
2, led display the whole screen parallel assembly: one is a simple parallel form, the other is an independent match in parallel form. Simple parallel way in the LED1-n head-to-tail parallel, the work of each LED to withstand the same voltage. This reliability is not high, but also against this issue to take an independent match in parallel form, with a driving effect, a single led display to protect the integrity of the failure does not affect other work, you can match the characteristics of a large difference.
3, led display cross array assembly: cross array shape is mainly to improve the reliability of the led display work, reduce the failure rate put forward.
4, led display mixed assembly: by the appeal of the parallel and the series of their respective advantages of the synthesis. Also includes two kinds. One is the first string after the mixed way, the other is the first and then the string of mixed way.
More than four led display assembly connection 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, led to a variety of display led connection failure, and ultimately affect product quality, while reducing user trust. This shows, led display assembly, the details of the success or failure!
