Issue
What is the life expectancy of the LCD display of smart sensors with available display?
Environment
Smart sensor with LCD display
Cause
Display life expectancy.
Resolution
- The Life expectancy of an LCD Display is 50K hours. Note: Life is reduced if LCD works under direct sunlight.
-
If you use a LED backlight in a LCD module the life expectancy of the LED is 30K to 50K hours, depending on the forward current. EL backlights are available but we don’t recommend them because of their short life (3K hours) and EMC problems. The AC voltage is generated by the DC to AC inverter.
