LED display and other electronic products, there is a service life. Although the theoretical life of the LED 100000 hours, 24 hours a day, 365 days a year can work more than 11 years, but the actual situation and the theoretical data is much worse, according to statistics, now on the market LED display life expectancy is generally 6 ~ 8 years, can be used for more than 10 years of LED screen has been counted as a very good, especially outdoor LED display, the life expectancy is even shorter. If we pay attention to some of the details of the use process, it will bring unexpected effects to our display.

Starting from the procurement of raw materials, to the standardization and normalization of the production and installation process, it will have a great impact on the service life of the LED display. The brand of electronic components such as lamp beads and IC, to the quality of the switching power supply, these are the direct factors affecting the life of the LED screen. When we make the planning of the project, we should specify the LED lamp beads with reliable quality, the switching power supply with good reputation, as well as the specific brand and model of other raw materials. In the process of production, we should pay attention to good anti-static measures, such as wearing a static ring, wear anti-static clothes, choose the dust-free workshop and production line to minimize the failure rate. Before leaving the factory, the aging time should be ensured as much as possible, so as to achieve 100% qualification rate of the factory. In the transportation of the shipment, should do a good job of product packaging, in the packaging outside the indication of fragile, if the sea, need to do a good job of anti-hydrochloric acid corrosion measures.

 

For outdoor LED display, to have the necessary peripheral safety equipment, do a good job of anti-lightning and anti-surge measures, try not to use the display in lightning storms. Pay attention to the protection of the environment, try not to be placed in a dusty environment for a long time, the display is strictly prohibited from entering the water inside, and do a good job of rainproof measures. Choose the right cooling equipment, according to the standard to install fans or air conditioning, screen environment as dry and ventilated as possible.

 

In addition, the daily maintenance of the LED display is also very important, regularly clean the screen above the accumulated dust, so as not to affect the heat dissipation function. In the playback of advertising content, try not to be in all white, all green and other images for a long time, so as not to cause current amplification, cable heating and cause short-circuit and other failures. In the evening when playing festivals, according to the environmental brightness can be adjusted screen brightness, which not only saves energy, but also extends the service life of the LED display.
