Can the LED display really be used for 100,000 hours?

The use of LED display is divided into indoor and outdoor, no matter indoor or outdoor, its service life is more than 100000 hours. General display parameters will be marked such as: mean time between failures: ≥10000 hours, half-life life: ≥50000 hours.
The theoretical lifespan of LED is 100,000 hours. According to 24 hours a day, 365 days a year, it can work for 11 years, and the half-life is 50,000 hours. The lifespan of an LED depends on the temperature. Using it at low brightness can greatly reduce heat generation and lower the temperature. Therefore, the life span of 30% brightness is about 10 times that of 100% brightness.
But the actual use is much different from the theoretical data.
According to statistics, the lifespan of LED displays on the market is generally 6 to 8 years, and the LED large screens that can be used for more than 10 years are considered very good, especially for outdoor LED displays, the lifespan is even shorter.
There are internal and external factors that affect the life of LED transparent screens.
Internal factors such as the performance of peripheral components, the performance of LED light-emitting devices, the fatigue resistance of products, the brand 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. For LED lamp beads, the main indicators are the following indicators: attenuation characteristics, waterproof vapor penetration characteristics, and anti-ultraviolet performance.
External factors include the working environment of the LED screen, etc. In terms of environment, the indoor temperature difference is small, without the influence of rain, snow and ultraviolet rays; the outdoor temperature difference can reach up to 70 degrees, plus wind, sun and rain. The harsh environment will increase the aging of the display screen, and the working environment is an important factor affecting the life of the transparent screen. Electronic products are a great test to the climate and temperature. The temperature, humidity and long-term ultraviolet radiation will affect the stability and life of the LED display.
The daily maintenance of the LED display is very important. Regularly clean the dust accumulated on the screen so as not to affect 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 festivals 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 display.
