The 7401-2xxx and 3xxx have either a 12.1-inch TFT (active matrix) or a
15-inch TFT.
LCD Adapter Board
The signals from the LCD header on the Processor Board are brought
to the LCD on a harness. Since there are multiple pin configurations
and connector types being used on the LCD, a small adapter board is
used to receive the LCD harness and map the signals into the correct
pin-out for the LCD panel. This board has a connector that plugs
directly into the LCD panel.
LCD Backlight Inverter Module
An Inverter Board supplies power for the LCD Backlight, which is a
separate module in the terminal. The inverter has a connector that
receives power, ground, and a Backlight dimming signal from the
Processor Board. The inverter generates the high voltage necessary to
start and run dual CCFL (cold-cathode fluorescent lamps) Backlights.
