LED Display Lifetime



The operational lifetime of an led screen for advertising outdoor is determined by the lifetime of the LEDs. LED Manufacturers estimate the life of led monitor to be 100,000 hours under certain operating conditions. LED Display end of lifetimes is when the frontal brightness has decreased to 50% of original brightness.





Three primary factors determine LED lifetime:

The manufacturing process of the LED

Driving (powering) method of the LED

Temperatures present at the LED die during operation



LED thermal management is vitally important to maintaining LED lifetime. Increasing the power through an LED increases brightness but reduces its lifetime due to increased heat generation. Increased exposure to higher temperature also shortens the lifetime. LED thermal management can only be done through the LED lead frame by conducting the heat to a Printed Circuit Board (PCB) and by allowing airflow to cool the LED lead frame.



LED Display components must be designed to handle a wide range of outdoor environmental factors, such as temperature and humidity. All components must be coated to protect from possible corrosion.
