Everyone knows that LED film screens always have a service life. In many cases, they are damaged due to various reasons before the "end of life" time. The service life of LED film screens is determined by many factors. It can be extended by replacing the power supply and other components, but the LED lamp beads cannot be replaced in large quantities, so once the life of the LED lamp beads ends, the life of the film screen is also over. Then from what aspects can we prolong the service life of the LED film screen? Next, Liancheng will introduce to you one by one.

First of all, we must find a way to prolong the life of LED lamp beads. Choosing high-quality epitaxial materials; increasing chip area, reducing current density, reducing thermal resistance; choosing packaging materials with excellent performance and strong UV resistance can make LED lamp beads last longer. The lamp bead is the key to the LED film screen, in short, find a way to prolong the life of the lamp bead.

Secondly, taking heat dissipation as a central task from module design to project implementation and even future system maintenance; reducing LED operating current; correctly configuring LEDs to make each primary color LEDs decay synchronously can prolong the service life of LEDs. That is to say, from the purchase 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 film screen.

The quality of electronic components such as lamp beads, IC, switching power supply, etc. will affect the service life of the LED film screen. Therefore, at the beginning of production, it is necessary to choose high-quality and quality-guaranteed components, and never try to be cheap, cut corners, and shoddy.

In addition, it can start from two aspects of device manufacturing and device application. From the perspective of device manufacturing: choose high-quality epitaxial materials; increase chip area, reduce current density; balance current density; reduce thermal resistance; choose packaging materials with excellent performance and strong UV resistance, etc. long.

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; correctly configuring LEDs to make the LEDs of each primary color decay synchronously can prolong the service life of LEDs.

That is to say, from the purchase 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 film screen. The brands of electronic components such as lamp beads and ICs, and the quality of switching power supplies are all direct factors that affect the life of LED large screens. 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.

During the transportation, 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 anti-hydrochloric acid corrosion measures. The daily maintenance of the LED transparent screen is also very important. The dust accumulated on the screen should be cleaned regularly to avoid affecting the heat dissipation function. When playing advertisement content, try not to stay in all white, all green and other screens for a long time, so as not to cause current amplification, cable heating and cause short circuit and other faults. When playing programs at night, the brightness of the screen can be adjusted according to the brightness of the environment, which can not only save energy, but also prolong the service life of the LED film screen.

The daily maintenance of the LED film screen is also very important, such as cleaning the screen regularly to avoid affecting heat dissipation. Let the screen rest for a period of time every day, and check the maintenance screen. When playing content, don’t stay in the same color screen all the time, especially the high-brightness screen, to avoid burning the screen due to high temperature. Also pay attention to the use environment, such as deactivation in bad weather and so on. The above is the introduction of the six methods to prolong the service life of the LED film screen organized by the editor of Liancheng, and the maintenance work should be done normally, so as to prolong the service life.
