Led display assembly is a complicated and complicated process. Each link requires engineering technicians to have a hard technical expertise to make the led display products to be refined and thin. Industry insiders know that led displays are assembled by a number of modules, which are assembled by a number of light beads. In the process of assembly of led display, the assembly step is followed by a ring and the ring should be careful, otherwise the effect of the led display will be affected. In order to meet the requirements of large area, high brightness, dynamic display and other applications of led display, and the driver matching requirement with led phase matching drive. Here are four forms of led display:
Led display screen is assembled in series: the led1-n and the head and tail of the general simple series connection mode are connected, and the current of the led screen is the same when working. The other is the improved way of the series with the bypass.
2. Integrated parallel assembly mode of led display screen: one is simple parallel form, and the other is the parallel form of independent matching. In simple parallel mode, led1-n in parallel, the voltage of each LED at work is the same. The reliability is not high, but also for parallel form adopted independent match about this problem, a single led display driver with good results, protection, complete failure does not affect other work, can match has many characteristics, such as bigger difference.
3. Assembly mode of led display cross-array: the cross array is mainly designed to improve the reliability of led display and reduce the failure rate.
4. Mixed assembly mode of led display screen: integrated with the advantages of parallel and series of the above, including 2 kinds. One is the first string and the other is the first and second string.
Each of the four led display modes has an advantage and disadvantage, which can be used according to different applications to select the most suitable mode of led display. Many engineers tend to ignore this, leading to a variety of connection failures in led displays, which ultimately affect product quality and reduce user trust. Thus, the assembly of led display screen, details determine success or failure!
