C.1 Auto-Dimming Configurations
The AFL series industrial monitor features an auto-dimming LCD that can automatically
adjust the backlight brightness according to the ambient light. If the auto-dimming function
is turned on, the backlight turns brighter when the ambient illuminance is high. The
backlight dims automatically when the ambient illuminance level is low.
The SI unit of illuminance is “lux.” Lux measures the intensity of light.
