Like other electronic products, LED display has a service life. Although the theoretical service life of LED is 100000 hours, and it can work for more than 11 years according to 24 hours a day and 365 days a year, the actual situation is much different from the theoretical data. According to statistics, the service life of LED display screen on the market is generally 6 ~ 8 years, and the large LED screen that can be used for more than 10 years is very good, especially the outdoor LED display screen. If we pay attention to some details in the use process, it will bring unexpected effects to our display screen.
From the procurement of raw materials to the standardization and standardization of production and installation process, it will have a great impact on the service life of LED display screen. The brands of electronic components such as lamp beads and IC, and the quality of switching power supply are the direct factors affecting the service life of LED large screen. When planning the project, we should specify the specific brands and models of reliable LED beads, well-known switching power supply and other raw materials. In the process of production, pay attention to anti-static measures, such as wearing electrostatic rings and anti-static clothes, and selecting dust-free workshops and production lines to minimize the failure rate. Before leaving the factory, the aging time shall be guaranteed as much as possible to achieve the factory qualification rate of 100%. During the transportation, the product shall be packaged well, and fragile shall be indicated on the outside of the package. In case of sea transportation, anti hydrochloric acid corrosion measures shall be taken.
For outdoor LED display screen, necessary peripheral safety equipment shall be provided, lightning protection and surge prevention measures shall be taken, and the display screen shall not be used in lightning and rainstorm weather. Pay attention to environmental protection. Try not to put it in a dusty environment for a long time. Water is strictly prohibited inside the display screen, and rainproof measures shall be taken. Select the correct heat dissipation equipment, install the fan or air conditioner according to the standard, and the screen environment shall be dry and ventilated as far as possible.
In addition, the daily maintenance of LED display screen is also very important. Regularly clean the dust accumulated on the screen to avoid affecting the heat dissipation function. When playing advertising content, try not to stay in all white, all green and other pictures for a long time, so as not to cause current amplification, cable heating and short circuit. When playing festivals at night, the screen brightness can be adjusted according to the ambient brightness, which can not only save energy, but also prolong the service life of LED display screen.
