In a certain sense, the lifespan of LED screens is determined by the LED chip’s lifespan. The lifespan of LED chip is usually defined as a period from luminescence intensity attenuation to the initial value of 50%. As a semiconductor material, it is often said that LED chips have 10 million hours of lifespan, but that is a assessment under ideal conditions. In the actual application, the lifespan of LED screens are not up to that much. Rental LED display screens have gradually appeared in the streets and dress up our city with different ways. But LED screen also has a lifespan, if there is no reasonable maintenance, it cannot be used for long time. Then what are the determining factors to the lifespan of LED screens? Here are the answers.
LED chip’s lifespan determines LED screen’s lifespan, but it does not mean LED chip’s lifespan is equal to the screen’s lifespan. When the rental LED screens are working, not every LED are working at full capacity. When the LED screen normally playing the video programs, the lifespan of LED screens should be about 8 times of LED chip’s, when the LED chips working with small current conditions, its lifespan can be longer. 1.The LED chips influence the lifespan of LED screens; LED chips are the most critical and most relevant components to the screen’s lifespan. For the LED chips, we should mainly considering the following indicators: attenuation characteristics, anti water and vapor permeability and anti-UV properties. If the LED screen rental service providers applied low quality LED chips into their screens, it will lead to lots of quality problems, also will affect the screen’s lifespan. 2.The production technology influence the lifespan of LED screens; The production process of rental LED display screens determines the screen’s anti-fatigue properties. The LED modules produced with low technology has poor anti-fatigue property. When the temperature and humidity changes, there will be cracks on the surface of circuit board, and resulting in reduced protective performance. As for most LED screen rental service providers, the accumulation of experience is very important, a factory with many years of experience in production process controlling will be more effective. 3.The matching components influence the lifespan of LED screens; In addition to LED chips, there are other components also influence the lifespan of LED screens: circuit boards, shell, switches, connectors, etc., if any component has quality problems, it may also shorten the screen’s lifespan. Therefore, the life of the shortest life of rental LED display screens is influenced by the components with shortest lifespan. For example, the LED chips, switches and shells have 8 years lifespan, but the protection performance of circuit board can only support its work for 3 years, then the circuit board may corroded after 3 years, then we can only get a 3 years Lifespan LED display. 4.The working environment influence the lifespan of LED screens; The lifespan of rental LED screens will also different in different application conditions. From the environmental aspect, indoor environment has smaller temperature difference, there is no rain/snow and UV influence; outdoor environment has larger temperature difference, wind, sun and rain damage. Harsh environment will aggravate the aging speed of LED screens. This is also an important factor affecting the lifespan of LED screens.
