Pay attention to these problems when installing LED displays in outdoor environm

LED display advertising media also has a high effective reach rate. Compared with media forms such as TV and newspapers, LED displays are cheaper. This unique value makes LED advertising screen media naturally become the upstart of outdoor media. Different from traditional outdoor media, LED full color screen is not only pure outdoor media. At the same time, it also has the characteristics and advantages of TV and other media. There is a large creative space, and there is a wide range of interaction and communication space with consumers. It is a unique form of screen that meets the needs of the individual and embraces the concept of digital communication.
Great wisdom.
This kind of problem we often encounter when using LED display. When the product is first used, the LED display can work normally, but after a period of time, there will be dark light, flicker, failure, intermittent lighting and other phenomena, which will seriously damage the product. According to Shenzhen-based LED display manufacturer Dayuan Smart, the reasons for this phenomenon are roughly as follows:
In the welding process, there are problems such as high welding temperature, long welding time, and inability to effectively prevent static electricity. More than 95% of the problems are caused by the packaging process.
The second is the quality problem of the LED display itself, that is, the production process problem.



Precautions
Strict control of the welding process;
Second, the aging test of the product.
The service life is an important guarantee to ensure the reliability of electronic products, and it is also a necessary link in the production of electronic products. This product improves performance after aging and helps maintain stable performance in later use. In product quality control, the aging test of LED displays is very important, but because it is easily overlooked, the aging test cannot be carried out correctly and effectively. According to the characteristics of the product failure rate curve, the LED aging test method is used to improve the reliability of the product, but this method is not required. At the end of the day, burn-in tests sacrifice the life of an individual LED product. pay
The aging methods of light-emitting diodes include constant current aging and constant voltage aging. A constant current source means that the current does not change at any time. There is a frequency issue, not constant current. That is, alternating current or pulsed current. AC or pulsating current sources can be designed to be constant rms, but such sources cannot be called constant current sources. Constant current aging is the characteristic of LED current work, and it is also a scientific method of LED aging. Impact overcurrent aging is also a new aging method adopted by Shenzhen LED display manufacturers. Using a constant current source with adjustable frequency and current, it is possible to judge the quality and life expectancy of LEDs in a short period of time, while also identifying potential problems that traditional aging methods cannot.
