LCD Backlight Inverter Module
Power
for
the
LCD
backlight
is
supplied
by
an
inverter
circuit,
which
is
integrated
on
the
LCD
controller
board
in
the
12.1”
LCD.
While
the
inverter
can
be
set
to
various
levels
of
brightness,
the
12.1”
LCD
can
only
turn
the
backlight
to
maximum
brightness
or
a
lower
brightness
for
dark
environments.
The
inverter
generates
the
high
voltage
necessary
to
start
and
run
a
dual
CCFL
backlight.
