Anyone who knows about LED displays should know that LED displays need to go through splicing and various inspections before they leave the factory. We have briefly learned about the inspection procedures that LED displays go through before leaving the factory. There is not too much here. The statement, next we mainly come to understand several different splicing technologies of LED display screens.

　　 First, it is the overall parallel connection of the LED display. One is a simple and common parallel connection, and the other is a parallel connection with this independent matching function. In the simple parallel connection, the first LED lamp to the Nth LED lamp are connected in parallel, and each LED bears an equal voltage during operation. This kind of reliability is not high, but to solve this problem, we often adopt an independent matching parallel form. This form has good driving effect, complete protection of a single LED display, and will not affect the work of other LED devices in the event of a failure, and can be matched. Features such as large differences in LED displays.

　The second is the overall tandem form. Generally speaking, a simple series connection method is to connect the first LED lamp to the Nth LED lamp end to end, and the same current flows through the LED display screen when it is working. The other is that the series connection with bypass is an improved way of simple series connection.

　　 There is also a cross-array form. The cross-array shape is mainly proposed to improve the reliability of the LED display screen and reduce the failure rate.

　　 Finally, there is a hybrid form. The advantages of parallel connection and series connection mentioned in the appeal are combined to form a mixed connection, which also includes two types. One is the series-first parallel and then the parallel, and the other is the first parallel and then the serial hybrid.

　　 Generally speaking, it can be said that all LED displays will go through the above-mentioned splicing before leaving the factory. Different splicing can make the LED display have different display functions, different working modes and power consumption.

　　Compared with traditional electronic products, outdoor LED displays are more complicated and changeable in terms of use time, installation procedures, etc., and they are also very simple in operation. Outdoor LED display manufacturers hereby remind everyone: in the process of using outdoor LED display, not only must pay attention to the methods and methods, but also be diligent in the maintenance of the display, so as to ensure the quality and life of the LED display products.

　　 1. Outdoor LED displays have the closest relationship with our users, and it is very necessary to do a good job of maintenance. Long exposure of LED to outdoor environment, wind, sun, dust, etc. can easily cause the display to be dirty.

　　 2. Water, iron powder and metal objects that are easy to conduct electricity are strictly prohibited from entering the screen. What are the maintenance tips for outdoor LED displays? Try to place the LED display in a low-dust environment. Large dust will affect the display effect. At the same time, too much dust will cause damage to the circuit. If the display is flooded, you should contact the electrician to cut off the power in time, and contact the professional personnel of the display for repair in time.
