In typical applications, use of a software addressable on/off FET
switch allows application software control of the LCD backlight.
The output from the FET switch triggers power sequencing in the
flat panel driver, effecting backlight control at the flat panel.
In a simpler application, direct application of backlight power to the
flat panel provides direct backlight control. Refer to documentation
from the flat panel manufacturer for recommended voltages and
control methods.
