Do you know the key factors that determine the longevity of transparent LED displays?

LED transparent screens also have a life span similar to other electronic products. Although the theoretical life of LED is 100000 hours, according to 24 hours a day, 365 days a year can work for more than 11 years, but the actual situation and theoretical data are very poor, according to statistics, now on the market LED transparent screen life is generally 4 to 8 years, can be used for more than 8 years LED transparent screen has been very good. Therefore, the LED transparent screen life of 100,000 hours is more ideal to achieve, the actual situation of the use of 50,000 hours is good.
Factors affecting the life of LED transparent screen are internal and external factors, internal factors have the performance of peripheral components, LED light emitting device performance, product fatigue resistance; Internal reasons have LED transparent screen of the working environment and so on.
LED for a long time to work light deterioration caused by aging, especially for high-power LED, light deterioration problem is more serious. When measuring the life of LED, it is far from enough to only take the damage of the lamp as the end of the life of LED display. It is more meaningful to specify the life of LED by the percentage of light attenuation of LED, such as 5% or 10%.
Light decay: When charging the surface of the photosensitive drum, the potential increases as the charge accumulates on the surface of the photosensitive drum, and finally reaches the "saturation" potential, which is the highest potential. The potential of the surface will decline over time, and the potential of the general operation is below this potential, the potential of the natural decline over time process, known as "dark decay" process. When the photosensitive drum is exposed by scanning, the potential of the dark area (refers to the surface of the photoconductor which is not illuminated by light) is still in the dark decay process; Bright area (refers to the light irradiated part of the photoconductor surface) in the photoconductive layer, the carrier density increases rapidly, the conductivity rises rapidly, the formation of photoconductive voltage, the charge disappears rapidly, the surface potential of the photoconductor also decreases rapidly. It's called "light decay," and it slows down.
