Today, LED display manufacturers will share with you how to make the LED display have a longer lifespan. The lifespan of an LED display is determined by a variety of factors. However, the end of life caused by many factors can be extended continuously through the replacement of parts (such as switching power supply). The LED is impossible to be replaced in large quantities, therefore, once the life of the LED ends, it means the end of the life of the display screen. In a certain sense, the life of the LED determines the life of the display.
In general, we can start from two aspects of device manufacturing and device application. From the perspective of device manufacturing: selecting high-quality epitaxial materials; increasing the chip area and reducing the current density; balancing the current density; reducing thermal resistance; selecting packaging materials with excellent performance and strong UV resistance, etc. .
From the perspective of device application: taking heat dissipation as a central task from module design to engineering implementation and even future system maintenance; reducing the LED operating current; correct configuration of the LED, so that the synchronous attenuation of each primary color LED can prolong the service life of the LED.

That is to say, from the procurement of raw materials to the standardization and standardization 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 switching power supply, these are the direct factors that affect the life of LED large screen. When we plan the project, we should specify the specific brands and models of reliable LED lamp beads, switching power supplies, and other raw materials. In the production process, we should pay attention to anti-static measures, such as wearing electrostatic rings, wearing anti-static clothes, choosing dust-free workshops and production lines to minimize the failure rate. Before leaving the factory, it is necessary to ensure the aging time as much as possible to achieve a 100% pass rate. During the transportation process, the product should be packaged well, and the fragile product should be marked on the outside of the package. If it is shipped by sea, it is necessary to take measures to prevent hydrochloric acid corrosion. The daily maintenance of the LED display is also very important. Regularly clean the dust accumulated on the screen so as not to affect the heat dissipation function. When playing advertising content, try not to stay in all white, all green, etc. for a long time, so as not to cause current amplification, cable heating and other faults such as short circuit. When playing programs at night, the brightness of the screen can be adjusted according to the ambient brightness, which not only saves energy, but also prolongs the service life of the LED display.
