The lifespan of LED displays is typically measured by "useful lifespan," not the time until they become completely unusable. The industry standard is that the useful lifespan ends when the display's brightness decays to 50% of its initial brightness. This time is usually between 50,000 and 100,000 hours.
Key factors affecting lifespan:
LED chip quality: The core factor. Using high-quality, anti-fading LED chips is the cornerstone of a long lifespan.
Operating environment: Prolonged exposure to high temperature and humidity significantly accelerates the aging of components and LED chips.
Usage intensity: Continuous use at maximum brightness for extended periods shortens lifespan.
Power supply quality: Unstable power supplies with surges can cause continuous damage to the entire system.
Heat dissipation design: Good heat dissipation effectively slows down light decay.
