The block diagram shows that AR-B9413 still need components to be
used for LCD panel. The inverter board provides the control for the
brightness of the LCD panel while the inverter is the one that
supplies the high voltage to drive the LCD panel. Each item will be
explained further in the section.

NOTE : Be careful with the pin orientation when installing connectors and
the cables. A wrong connection can easily destroy your LCD
panel. The pin 1 of the cable connectors is indicated with a
sticker and the pin1 of the ribbon cable is usually with
different color.
The inverter board is the one that supplies the high voltage signals to
drive the LCD panel by converting the 12 volt signal from the
AR-B9413x into high voltage AC signal for LCD panel.
It can be installed freely on the space provided over the VR board, if
the VR board is installed on the bracket, you will have to provide a
place to install the inverter board into your system.
