LED display lifespan
High quality LED display's excellent visual performance and long lifespan are decided by the
following factors:high quality raw material,scientific design ,advanced production techniques,rich
installation and operation experience good maintenance and etc.
The operational lifetime of an LED Display is determined by the lifetime of the LEDs. LED
Manufacturers estimate the LED lifetime to be 100,000 hours under certain operating conditions.
LED Display end of lifetimes is when the frontal brightness has decreated to 50% of original
Three primary factors determine LED lifetime:
Manufacturing process of the LED
Driving (powering) method of the LED
Temperatures present at the LED die during operation
LED thermal management is vitally importent to maintaining LED lifetime. Increasing the power throught an LED
increases brightness but reduces its liftetime 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 mush be coated to protect from possible corrosion.
