It is not easy to assemble all the LED electronic displays , just like configuring an assembled computer. Even the LED electronic display is more complicated to assemble, and more steps to be taken. It is connected by a number of modules, and the module is assembled by a number of lamp beads. The steps are one ring and one ring, the ring should be careful, otherwise the LED electronic display effect will be affected. . The LED display is important in terms of connection. Once a connection is not good, the next link will not work properly. Only by understanding the knowledge of these aspects, the led display will be safer and better, because it is also related to the high brightness power of the led display. The high-power high-brightness LED of a single package is expensive , and it is now put into practical use. The power of a single high-brightness led display is small. Therefore, it is necessary to arrange a plurality of LED display screens according to requirements, on the one hand, it can meet the requirements of a large range, high brightness, dynamic display, color change and the like, and on the other hand, can satisfy the driving of the driver matched with the LED . Matching requirements. The following mainly introduces the four LED electronic display connection forms: First, the overall series form: the LED1-n in the simple serial connection mode is connected end to end, and the current flowing through the led display is equal. The other is an improved way of bypassing the series connection of 1.1 . Second, the overall parallel form: one is a simple parallel form, and the other is an independently matched 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. Third, the mixed form: 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. Fourth, the cross-array form: cross-array shape is mainly to improve the reliability of the led display work, reduce the failure rate proposed. In summary, the LED display screens are connected in a variety of ways, and each step does not allow connection errors. Therefore, this must be understood by engineers and technicians. The above four connection forms have their own advantages and disadvantages. Analysis, and finally find yourself suitable for connecting led display form. Many engineering and technical people often ignore this point, leading to a variety of problems in the LED display , and ultimately let customers lose confidence in the company. It is thus found that often a small detail determines success or failure, so the LED display technology must be refined and fine. I believe this is also the culture advocated by every company !
