Specifically:

The theoretical lifespan of an LED screen can reach approximately 100,000 hours, and under normal usage conditions, it can even last for decades.

The lifespan of an LCD screen is relatively shorter, with a maximum lifespan of about 50,000 hours and an average of around 30,000 hours.

However, it should be noted that the actual lifespan is affected by various factors such as the usage environment and user habits.
