LED display installation in the outdoor environment should pay attention to the problem

Led display advertising media also has a high effective reach rate. LED displays are cheaper than other forms of media such as television and newspapers. 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 a wide range of interactive communication space with consumers. It is a unique form of screen that can meet the needs of individuals and has the idea of digital communication.

Great wisdom.

This kind of problem we often encounter when using LED display. When the product is used, the LED display can work normally, but after a period of time, there will be dark light, flickering, failure, intermittent lighting and other phenomena, which seriously damage the product. According to Shenzhen-based led display manufacturer Dayuan Intelligence, the reasons for this phenomenon are roughly as follows:

In the process of welding, there are some problems such as high welding temperature, long welding time and can not effectively prevent static electricity. More than 95% of these problems are caused by the packaging process.

The second is the quality of the LED display itself, that is, the production process.

Preventive measures

Strict control of the welding process;

2. Aging test of products.

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. The product improves performance after aging and helps maintain stable performance in later use. In product quality control, the aging test of LED display is very important, but because it is easy to be ignored, it can not be correctly and effectively carried out aging test. 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 it is not required to use this method. In the end, aging tests sacrifice the life of individual LED products. pay

The aging mode of LED has constant current aging and constant voltage aging. Constant current source means that the current is constant at all times. There is a frequency problem, not a constant current. That's 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 operation, and it is also a scientific method of LED aging. Impact overcurrent aging is also a new aging method used by Shenzhen LED display manufacturers. Using a constant current source with adjustable frequency and current, the quality and life expectancy of the LED can be judged in a short time, and potential problems that cannot be found by traditional aging methods can also be identified.
