Precautions for installing LED display screens in outdoor environments

LEDs display advertising media also have a high effective reach rate. LED displays are relatively cheaper compared to media forms such as television and newspapers. This unique value makes LED advertising screen media a natural newcomer to outdoor media. Unlike traditional outdoor media, LED full-color screens are not just pure outdoor media. It also possesses the characteristics and advantages of media such as television. There is ample creative space and extensive interaction and communication with consumers. This is a unique screen form that can meet individual needs and embodies the concept of digital communication.

We often encounter this problem when using LED displays. When the product is first used, the LED display screen can work normally, but after a period of time, phenomena such as low light, flickering, malfunction, and intermittent lighting may occur, seriously damaging the product. According to Shenzhen based LED display manufacturer Dayuan Intelligence, the reasons for this phenomenon are roughly as follows:

There are problems such as high welding temperature, long welding time, and ineffective prevention of static electricity during the welding process. More than 95% of the problems are caused by packaging processes.

The second issue is the quality of the LED display screen itself, which is a production process problem.

preventive measures

Strictly control the welding process;

Aging test of the product

The service life is an important guarantee for ensuring the reliability of electronic products and a necessary link in the production of electronic products. This product can improve the performance after aging and help maintain stable performance in later use. In product quality control, aging testing of LED displays is very important, but due to its easy neglect, it cannot be conducted correctly and effectively. Based on the characteristics of the product failure rate curve, the LED aging test method is adopted to improve the reliability of the product, but this method is not required. Ultimately, aging testing sacrifices the lifespan of individual LED products.

The aging methods of light-emitting diodes include constant current aging and constant voltage aging. A constant current source refers to a current that remains constant at all times. There is a frequency issue, not a constant current. That is to say, alternating current or pulsed current. An AC or pulsating current source can be designed with a constant effective value, but this type of power source cannot be called a constant current source. Constant current aging is a characteristic of LED current operation and a scientific method for LED aging. Impact overcurrent aging is also a new aging method adopted by Shenzhen LED display manufacturers. By using a constant current source that can adjust both frequency and current, the quality and expected lifespan of LEDs can be determined in a short period of time, while also identifying potential issues that traditional aging methods cannot detect.
